Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..319af6b --- /dev/null +++ b/ChangeLog @@ -0,0 +1,102 @@ +=========1.4w10UCIb15=========== +- Due to refactoring time stamps in Windows would be written twice. +This has been fixed. +- More refactoring; the number of #ifdef _WIN32's has again been +drastically reduced. +=========1.4w10UCIb14=========== +- option to alter priority now also works on windows +(Eric Mullins) +- refactoring so that posix and win32 part share more +code +- a number of potential busy loop scenarios have been eliminated +in the Windows code (Windows uses polling) +- the return value of CreateProcess is now checked +=========1.4w10UCIb13=========== +- perft mode exposed. +=========1.4w10UCIb12=========== +- Replaced %lld everywhere by S64_FORMAT. +=========1.4w10UCIb11=========== +- Crash bug fix (wrong parentheses in instruction that checked for help +option). +=========1.4w10UCIb10=========== +- It is now possible to do "make rpm" to make an rpm binary package. +- Trivial bug fixes. +- Documentation added for epd-test functionality (man page). +- Cosmetic cleanups of output of epd-test. +- "polyglot --help" output added. +- Added polyglot book format specification to distribution. +=========1.4w10UCIb9=========== +- Trivial cosmetic fixes +- Some engines do not support the "Hash" options. +So we do not send memory=1 in that case. +=========1.4w10UCIb8=========== +- Support for egtpath command in xboard protocol +=========1.4w10UCIb7=========== +- Debianization: it is now possible to do "make deb" to build a Debian/Ubuntu +package. +=========1.4w10UCIb6=========== +- UCI GUI support added.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 6. Often, you can also type `make uninstall' to remove the installed + files again. + +Compilers and Options +===================== + +Some systems require unusual options for compilation or linking that the +`configure' script does not know about. Run `./configure --help' for +details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + +You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + +Installation Names +================== + +By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + +Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + +There may be some features `configure' cannot figure out automatically, +but needs to determine by the type of machine the package will run on. +Usually, assuming the package is built to be run on the _same_ +architectures, `configure' can figure that out, but if it prints a +message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + +If you want to set default values for `configure' scripts to share, you +can create a site shell script called `config.site' that gives default +values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + +Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf bug. Until the bug is fixed you can use this workaround: + + CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + +`configure' recognizes the following options to control how it operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..49e424b --- /dev/null +++ b/Makefile.am @@ -0,0 +1,25 @@ +#AM_CPPFLAGS=-DDEBUG +#AM_CXXFLAGS=-g + +bin_PROGRAMS = polyglot +polyglot_SOURCES = adapter.cpp attack.cpp board.cpp book.cpp book_make.cpp book_merge.cpp colour.cpp engine.cpp epd.cpp fen.cpp gui.cpp game.cpp hash.cpp io.cpp line.cpp list.cpp main.cpp move.cpp move_do.cpp move_gen.cpp move_legal.cpp option.cpp parse.cpp pgn.cpp piece.cpp pipe.cpp posix.cpp random.cpp san.cpp search.cpp square.cpp uci.cpp uci2uci.cpp util.cpp adapter.h colour.h hash.h move_gen.h piece.h uci2uci.h attack.h config.h gui.h io.h move.h pipe.h posix.h uci.h board.h engine.h line.h move_legal.h random.h util.h book.h epd.h list.h option.h san.h book_make.h fen.h main.h parse.h search.h book_merge.h game.h move_do.h pgn.h square.h + +dist_doc_DATA = README README1.3 README1.4 README1.4w README1.4w10UCI book_format.html + +man6_MANS = polyglot.man + +polyglot.man: polyglot.pod + pod2man -c "" -r "" -s 6 polyglot.pod > polyglot.man + +README: polyglot.man + groff -t -e -mandoc -Tascii polyglot.man| col -bx > README + +deb: + dpkg-buildpackage + +rpm: + make dist + rpmbuild -ta polyglot-@VERSION@.tar.gz + +EXTRA_DIST=makefile.gcc polyglot.man polyglot.pod polyglot.spec debian/changelog debian/control debian/docs debian/README debian/compat debian/copyright debian/files debian/polyglot.substvars debian/rules + diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..3dc2037 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,705 @@ +# Makefile.in generated by automake 1.10.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, +# 2003, 2004, 2005, 2006, 2007, 2008 Free Software Foundation, Inc. +# This Makefile.in is free software;

It connects a GUI interface (such as + XBoard, Winboard, Arena or Chessbase) to a UCI chess engine. + + By specifying an opening book (in PolyGlot book format) chess engines + can transparently use such books. + + PolyGlot understands the two main GUI protocols: UCI and xboard. Nor- + mally the protocol will be auto detected but this can be overridden in + the configuration file. + + In xboard mode PolyGlot fully translates between the xboard and UCI + protocols. In addition it tries to solve known problems with other + adapters. For instance, it detects and reports draws by fifty-move + rule, repetition, etc ... It also supports Chess960. + + When in UCI mode PolyGlot mostly passes commands from the GUI to the + engine and vice versa, except that it will play book moves on behalf of + the engine when the occasion arises. + + Book making utilities + + PolyGlot supports the "PolyGlot opening book format". This is the + defacto standard non-proprietary opening book format. It is fully docu- + mented here + + http://alpha.uhasselt.be/Research/Algebra/Toga/book_format.html + + Roughly speaking a PolyGlot opening book is a collection of triples + (position, move, weight). A "position" is represented by a 64-bit + Zobrist hash key. The weight is proportional to the probability the + move should be played. + + Other opening book formats such as ChessBase's .ctg format and Arena's + .abk format are undocumented and proprietary. They can only be used by + their own GUIs. + + PolyGlot can compile a pgn file into a binary PolyGlot book and fur- + thermore it can merge two such binary books into a third one. + + Epd test mode + + In epd test mode, PolyGlot will search positions in an epd file and + record the number of times the right best move was found. The argu- + ments specify when to stop the search in any given position. + + Perft counts + + A perft count is the number of legal move sequence in a given position + up to a given depth. PolyGlot can perform such perft counts. It is how- + ever much slower than other more dedicated programs. + +OPTIONS + When invoked without options or with a config file as argument PolyGlot + acts as an adapter. The config file format is documented below. The + default config file is "polyglot.ini". + + When invoked as + + polyglot make-book + + PolyGlot supports the following options + + -pgn (default: "book.pgn") + Input file in pgn format. + + -bin (default: "book.bin") + Output file in PolyGlot format. + + -max-ply (default: 1024) + Specifies the maximum ply-depth of lines included in the book. + + -min-game (default: 3) + Specifies the minimum number of games that have to contain this + move for it to be included in the book. + + -min-score (default: 0.0) + Specifies the minimum score (or weight) this move should have + received for it to be included in the book. The score is + 2*(wins)+(draws), globally scaled to fit into 16 bits. + + -only-white + Include only moves for white in the book. + + -only-black + Include only moves for black in the book. + + -uniform + Set all weights to 1. In other words, all moves will be selected + with equal probability. + + When invoked as + + polyglot merge-book + + PolyGlot supports the following options + + -in1 + First input file (in PolyGlot book format). + + -in2 + Second input file (in PolyGlot book format). + + -out (default: out.bin) + Output file (in PolyGlot book format). + + Input files are not symmetrical, "in1" has priority over "in2". In + other words when a position occurs both in "in1" and "in2" only the + moves and weights from "in1" will be retained in "out". + + When invoked as + + polyglot epd-test + + (possibly with a config file as first argument) PolyGlot supports the + following options + + -max-depth (default: 63) + Unconditionally stop the search when this depth has been reached. + + -max-time (default: 5.0) + Unconditionally stop the seach after this amount of time. + + -depth-delta (default: 3) + Stop the search if the best move has been constant for this many + depths, on condition that the mininal depth and minimal time have + been reached. + + -min-depth (default: 8) + Minimal search depth when the search is stopped using + "-depth-delta". + + -min-time (default: 1.0) + Minimal search time when the search is stopped using + "-depth-delta". + + When invoked as + + polyglot perft + + PolyGlot supports the following options + + -fen (default: starting position) + Fen at which to start searching. + + -max-depth (default: 1) + Maximum depth to search. + +CONFIG FILE FORMAT + There should be a different config file for each engine. + + The config file is in the traditional INI format. + + [PolyGLot] + option = value + ... + [Engine] + option = value + ... + + Lines starting with "#" are ignored. + + NOTE: There can be spaces in option names or values. Do not use + quotes. Boolean values are written as "true" or "false". + + [PolyGlot] section + + This section is used by PolyGlot only. The engine is unaware of these + options. The list of available options is detailed below. + + EngineName (default: UCI name) + This is the name that will appear in the GUI. It is cosmetic only. + You can use different names for tweaked versions of the same + engine. + + EngineDir (default: ".") + Full path of the directory where the engine is installed. You can + use "." (without the quotes) if you know that PolyGlot will be + launched in the engine directory or the engine is in the "path" and + does not need any data file. + + EngineCommand + Put here the name of the engine executable file. You can also add + command-line arguments. Path searching is used and the current + directory will be "EngineDir". + + Log (default: false) + Whether PolyGlot should log all transactions with the interface and + the engine. This should be necessary only to locate problems. + + LogFile (default: polyglot.log) + The name of the log file. Note that it is put where PolyGlot was + launched from, not into the engine directory. + + WARNING: Log files are not cleared between sessions, and can become + very large. It is safe to remove them though. + + Resign (default: false) + Set this to "true" if you want PolyGlot to resign on behalf of the + engine. + + NOTE: Some engines display buggy scores from time to time although + the best move is correct. Use this option only if you know what + you are doing (e.g. you always check the final position of games). + + ResignMoves (default: 3) + Number of consecutive moves with "resign" score (see below) before + PolyGlot resigns for the engine. Positions with only one legal + move are ignored. + + ResignScore (default: 600) + This is the score in centipawns that will trigger resign "count- + ing". + + ShowPonder (default: true) + Show search information during engine pondering. Turning this off + might be better for interactive use in some interfaces. + + KibitzMove (default: false) + Whether to kibitz when playing a move. + + KibitzPV (default: false) + Whether to kibitz when the PV is changed (new iteration or new best + move). + + KibitzCommand (default: "tellall") + xboard command to use for kibitzing, normally "tellall" for kibitz- + ing or "tellothers" for whispering. + + KibitzDelay (default: 5) + How many seconds to wait before starting kibitzing. This has an + effect only if "KibitzPV" is selected, move kibitzes are always + sent regardless of the delay. + + UCI (default: false) + If true PolyGlot will not understand xboard commands. + + Book (default: false) + Indicates whether a PolyGlot book should be used. This has no + effect on the engine own book (which can be controlled with the UCI + option "OwnBook" in the [Engine] section). In particular, it is + possible to use both a PolyGlot book and an engine book. In that + case, the engine book will be used whenever PolyGlot is out of + book. Remember that PolyGlot is unaware of whether the engine is + itself using a book or not. + + Chess960 (default: false) + Play Chess960 (also called Fischer Random Chess or FRC), + + MateScore (default: 10000) + Mate score reported to GUI when in xboard mode. + + BookFile (default: book.bin) + The name of the (binary) book file. Note that PolyGlot will look + for it in the directory it was launched from, not in the engine + directory. Of course, full path can be used in which case the cur- + rent directory does not matter. + + NOTE: When using PolyGlot with a UCI GUI this parameter can be set + via the UCI option "Polyglot BookFile". + + BookRandom (default: true) + Select moves according to their weights in the book. If false the + move with the highest weight is selected. + + BookLearn (default: false) + Record learning information in the opening book. Naturally this + requires the opening book to be writable. + + UseNice (default: false) + Run the engine at nice level 5, or "NiceValue" if it set. On some + operating systems it may be necessary to run the engine at lower + priority for it to be responsive to commands from PolyGlot while + searching. + + NiceValue (default: 5) + Nice levels go from -20 to 20 with 20 being the lowest priority. + On Unix only root can set negative nice levels. On Windows the + standard Win32 priority levels are mapped in a sensible way to Unix + nice levels. + + Affinity (default: -1) + This a bit vector in which each bit represents the processors that + a process is allowed to run on. This option works only on Windows. + + Work arounds + + Work arounds are identical to options except that they should be used + only when necessary. Their purpose is to try to hide problems with + various software (not just engines). The default value is always cor- + rect for bug-free software. + + IMPORTANT: Any of these work arounds might be removed in future ver- + sions of PolyGlot. You are strongly recommended to contact the author + of faulty software and truly fix the problem. + + PolyGlot supports the following work arounds: + + UCIVersion (default: 2) + The default value of 2 corresponds to UCI+. Use 1 to select plain + UCI for engines that have problems with UCI+. + + CanPonder (default: false) + PolyGlot now conforms to the documented UCI behaviour: the engine + will be allowed to ponder only if it (the engine) declares the + "Ponder" UCI option. However some engines which can actually pon- + der do not declare the option. This work around lets PolyGlot know + that they can ponder. + + SyncStop (default: false) + When a ponder miss occurs, Polyglot interrupts the engine and IMME- + DIATELY launches a new search. While there should be no problem + with this, some engines seem confused and corrupt their search + board. "SyncStop" forces PolyGlot to wait for the (now useless) + ponder search to finish before launching the new search. + + PromoteWorkAround (default: false) + Some engines do not specify a promotion piece, e.g. they send + "e7e8" instead of the correct "e7e8q". This work around enables + the incorrect form (and of course promotes into a queen). + + RepeatPV (default: true) + When true, PolyGlot repeats the last pv string (which also contains + score,depth and time usage) it got from the engine. Some engines + however do not send a new pv string just before sending the move + and the now old pv string might confuse debugtools that parse the + winboard debug files. + + [Engine] section + + This section contains engine UCI options. PolyGlot does not understand + them, but sends the information to the engine at startup (converted to + UCI form). You can add any UCI option that makes sense to the engine + (not just the common options about hash-table size and tablebases). + + NOTE: use INI syntax, not UCI.

The bug is related to +searching in draw positions (e.g. 50-move rule or repetition). I had +only been able to make PolyGlot crash by using analysis mode and +performing manual takebacks. I believe that this bug can only happen +in highly-interactive use (e.g. manual analysis). It is present in +all versions of PolyGlot, including this one. + +I attempted a work around in February. I vaguely remember the change +prevents crashing (not sure) but it is possible that PolyGlot now gets +stuck in some rare case, i.e. it refuses to produce a move. In any +case, the bug cannot occur silently, e.g. in a game that terminated +normally. + +Because of the small expected impact (nobody ever reported it to me) +and because fixing the bug would require a whole redesign of the +xboard module, I have no intention of working on it at the moment (!). + +Make sure to let me know if it appeared in any circounstance, thanks! +In particular if the bug ever occurs during a non-interactive session +(e.g. engine vs. engine game), then I will do something. + + +Thanks +------ + +Big thanks go to: + +- Dann Corbit for spending a lot of time compiling, testing, making + files available, etc ... + +- Leo Dijksman for hosting the PolyGlot distribution on his web site + (see Links) and also for thorough testing + +- Tord Romstad, Joshua Shriver and George Sobala for compiling and + testing on Mac OS X + +- users in the WinBoard forum for their feedback and encouraging + words: Roger Brown, Leo Dijksman, Igor Gorelikov, Mogens Larsen, + Volker Pittlik, Norm Pollock, Günther Simon and Salvo Spitaleri + in particular + + +Links +----- + +- Tim Mann's Chess Pages: http://www.tim-mann.org/xboard.html +- Leo Dijksman's WBEC Ridderkerk: http://wbec-ridderkerk.nl/ +- Volker Pittlik's Winboard Forum: http://wbforum.volker-pittlik.name/ + + +Contact me +---------- + +You can contact me at fabien_letouzey@hotmail.com + +If I am not available, you can discuss PolyGlot issues in Volker +Pittlik's Winboard Forum: http://wbforum.volker-pittlik.name/ + +In fact for questions regarding specific Windows-only engines, you are +advised to ask directly in the WinBoard forum, as I don't have Windows +myself. + + +The end +------- + +Fabien Letouzey, 2005/06/03. + diff --git a/README1.4 b/README1.4 new file mode 100644 index 0000000..edd4e8f --- /dev/null +++ b/README1.4 @@ -0,0 +1,615 @@ + +Legal details +------------- + +PolyGlot 1.4 Copyright 2004-2006 Fabien Letouzey. + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or (at +your option) any later version. + +This program is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Polyglot book format

+The following description of the Polyglot book format is obtained +by inspecting the freely available source code of Polyglot. +

A note on copyright

I believe that the algorithm described +below may be freely implemented by all GUIs, adapters and engines, +including closed source ones. Polyglot itself is GPL but the GPL only +covers actual code and not algorithms. +

+The array of 781 random numbers is of course taken from the Polyglot +source code but I am pretty sure that a table of random numbers +cannot be covered by copyright. +

+Look below for some sample code which is released +in the public domain. +

+At the end of this document we discuss an extension of the Polyglot +opening book format for Chess960. This extension is implemented in +upcoming versions of xboard/winboard. +

Outline

+A Polyglot book is a series of "entries" of 16 bytes +

+

+key    uint64
+move   uint16 
+weight uint16
+learn  uint32
+
+

+All integers are stored highest byte first (regardless of size) +

+The entries are ordered according to key. Lowest key first. +

+

key

+"key" is a 64 bit hash of a board position. Its computation +is explained below. +

+The starting point is given by the following declaration + +

+
+#ifdef _MSC_VER
+#  define U64(u) (u##ui64)
+#else
+#  define U64(u) (u##ULL)

+The array Random64 is in fact a concatenation of four subarrays +
+RandomPiece     (offset:   0, length: 768)
+RandomCastle    (offset: 768, length:   4) 
+RandomEnPassant (offset: 772, length:   8)
+RandomTurn      (offset: 780, length:   1)
+
+"key" is a so-called "Zobrist hash function". In other words it is +the exclusive or of entries taken from each of the +subarrays described above. + +Thus we have +
+key=piece^castle^enpassant^turn;
+
+ +

piece

+"piece" is the exclusive or of entries from +RandomPiece, one for each piece on the board. The offset of the entry +in RandomPiece corresponding to a piece is computed as follows. +
+offset_piece=64*kind_of_piece+8*row+file;
+
+"row" and "file" are counted from 0 to 7. With this convention one has +
+square      file   row
+======================
+a1             0     0
+h1             7     0
+a8             0     7
+h8             7     7
+
+ +"kind_of_piece" is encoded as follows +
+black pawn    0
+white pawn    1
+black knight  2
+white knight  3
+black bishop  4
+white bishop  5
+black rook    6
+white rook    7
+black queen   8
+white queen   9
+black king   10
+white king   11
+
+ +

castle

+"castle" is the exclusive or of entries from +RandomCastle. The offsets are computed as follows. +
+white can castle short     0
+white can castle long      1
+black can castle short     2
+black can castle long      3
+
+If none of these flags apply then castle=0. +

+Note that these flags represent "potential future castling" as in the +FEN standard even if such castling is currently not possible due to blocking +pieces or enemy attacks. +

+In other words these flags are all true in the starting position and are +only updated after the appropriate king, rook or castling moves. + + + +

enpassent

If the opponent has performed a double pawn push +and there is now a pawn next to it belonging to the player to move then +"enpassant" is the entry from RandomEnPassant whose offset is the file +of the pushed pawn (counted from 0(=a) to 7(=h)). If this does not +apply then enpassant=0. +

+Note that this is different from the FEN standard. In the FEN standard +the presence of an "en passant target square" after a double pawn push +is unconditional. +

Also note that it is irrelevant if the potential en passant +capturing move is legal or not (examples where it would not be legal are +when the capturing pawn is pinned or when the double pawn push was a +discovered check). + + +

turn

+If white is to move then "turn" is the sole entry of RandomTurn. +If not then "turn" is zero. + +

move

+"move" is a bit field with the following meaning (bit 0 is the least +significant bit) +
+bits                meaning
+===================================
+0,1,2               to file
+3,4,5               to row
+6,7,8               from file
+9,10,11             from row
+12,13,14            promotion piece
+
+"promotion piece" is encoded as follows +
+none       0
+knight     1
+bishop     2
+rook       3
+queen      4
+
+If the move is "0" (a1a1) then it should simply be ignored. It seems to me that +in that case one might as well delete the entry from the book. + +

Castling moves

Castling moves are represented somewhat +unconventially as follows (this convention is related to Chess960, see +below). +
+white short      e1h1
+white long       e1a1
+black short      e8h8
+black long       e8a8
+
+It is technically possible that these moves are legal non-castling +moves. So before deciding that these are really castling moves the +implementation may for example verify that there is really a king +present on e1/e8. +

weight

+In the Polyglot source code this field is called "count" but it is in fact +a measure for the quality of the move. It should be at least one. +

+The Polyglot book generator sets it to 2*(wins)+(draws), globally +scaled to fit into 16 bits. A move with a weight of zero is deleted +from the book. This is just a convention and book authors +are free to set this field according to their taste (as long as it is at least one). +

+If random play is enabled in Polyglot then the probability that +a move is selected is its weight divided by the sum of the weights +of all the moves in the given position. +

A note on zero weights

+Polyglot assumes that weights are at least one since a zero +weight means the move should not be played, and hence you might as +well delete the entry from the book (which the Polyglot book generator does). + +Nonetheless, if you really insist, an entry with zero weight can be +approximated by giving it very low probability. This is what Scid does. + +

learn

"learn" is set to zero by the Polyglot book generator. +If you set "BookLearn=true" in polyglot.ini then this field +is used to record learning information. However I do not know of any +program that uses this information. Also this means the Polyglot should +have write access to the opening book which on Unix systems will probably +not be the case if the book has been installed centrally. +

+

Sample code

+The following sample code is released in the public domain. +
    +
  • +pg_key.c: This little utility computes the PG key +of a FEN. Note that it does ZERO error checking on the legality +of the FEN and hence will segfault if something is wrong. +
    • +
  • +pg_show.c: This utility looks up a PG key in a PG book +and prints out the moves and their (relative) weights. +
    • +
+

+Here are a few utilities: pg_utils-0.2.tar.gz. They are released under the FreeBSD license. +

Extension to Chess960

+We assume that the reader is familar +with the rules of Chess960 (also called Fisher Random Chess or +FRC). See e.g. +http://en.wikipedia.org/wiki/Fischer_Random_Chess. +

+The Zobrist hash function used in Polyglot does not keep track of +which rook has castling rights if there are multiple rooks present on +the same side of the king. However it is rather unlikely that this +situation would occur in the opening. So the ambiguity can be resolved +in a satisfactory way by making the following convention. +

+ Positions in which a rook has castling rights which is not an outer +rook (closest to a or h file) should not be included in the book. +

+Nonetheless this is an unsatisfactory situation. Therefore the +upcoming versions of xboard/winboard extend the Polyglot hash function +in such a way that it takes into account the full castling rights in +Chess960, therefore +removing the need of the above disambiguating convention. This is done in a backward compatible way. I.e. ordinary +chess positions or Chess960 positions in which there is no castling +ambiguity will keep their old hash key. +

+The above declaration of RandomCastle is replaced by +

+const uint64 RandomCastle[16]={
+< to be filled in >
+}
+
+In this case "castle" will be the exclusive or of entries taken from +RandomCastle, one for each rook that has castling rights (so at most +four offsets). + +The offset for a rook that has castling rights is computed as follows. +
    +
  • If the rook is an outer rook (i.e. closest to the a or h file) then +the offset is +
    +0    if the rook is white and on the king side
+1    if the rook is white and on the queen side
+2    if the rook is black and on the king side
+3    if the rook is black and on the queen side
+
    +(this is like in ordinary chess) +
    • +
  • If the rook is not an outer rook then the offset is +
    +3+file    if the rook is white
+9+file    if the rook is black
+
    +where "file" denotes the file the rook is on, encoded in the usual way, i.e. +b=1,c=2,d=3,e=4,f=5,g=6. +

A castling move is encoded as a usual move +(see above) in which the "from square" is the position of the king and +the "to square" is the position of the rook. This is to maintain +compatibility with various Fruit derivatives. + + + + + diff --git a/book_make.cpp b/book_make.cpp new file mode 100644 index 0000000..ffffc9b --- /dev/null +++ b/book_make.cpp @@ -0,0 +1,540 @@ + +// book_make.cpp + +// includes + +#include +#include +#include +#include +#include + +#include "board.h" +#include "book_make.h" +#include "move.h" +#include "move_do.h" +#include "move_legal.h" +#include "pgn.h" +#include "san.h" +#include "util.h" + +// constants + +static const int COUNT_MAX = 16384;

The list of available options is detailed below. + +=over 4 + +=item B (default: UCI name) + +This is the name that will appear in the GUI. It is +cosmetic only. You can use different names for tweaked versions of +the same engine. + +=item B (default: ".") + +Full path of the directory where the engine is installed. You can use +"." (without the quotes) if you know that PolyGlot will be launched in +the engine directory or the engine is in the "path" and does not need +any data file. + +=item B + +Put here the name of the engine executable file. You can also add +command-line arguments. Path searching is used and the current +directory will be "EngineDir". + +=item B (default: false) + +Whether PolyGlot should log all transactions with the interface and +the engine. This should be necessary only to locate problems. + +=item B (default: polyglot.log) + +The name of the log file. Note that it is put where PolyGlot was +launched from, not into the engine directory. + +WARNING: Log files are not cleared between sessions, and can become +very large. It is safe to remove them though. + +=item B (default: false) + +Set this to "true" if you want PolyGlot to resign on behalf of the +engine. + +NOTE: Some engines display buggy scores from time to time although the +best move is correct. Use this option only if you know what you are +doing (e.g. you always check the final position of games). + +=item B (default: 3) + +Number of consecutive moves with "resign" score (see below) before +PolyGlot resigns for the engine. Positions with only one legal move +are ignored. + +=item B (default: 600) + +This is the score in centipawns that will trigger resign "counting". + +=item B (default: true) + +Show search information during engine pondering. Turning this off +might be better for interactive use in some interfaces. + +=item B (default: false) + +Whether to kibitz when playing a move. + +=item B (default: false) + +Whether to kibitz when the PV is changed (new iteration or new best move). + +=item B (default: "tellall") + +xboard command to use for kibitzing, normally "tellall" for kibitzing +or "tellothers" for whispering. + + +=item B (default: 5) + +How many seconds to wait before starting kibitzing. This has an +effect only if "KibitzPV" is selected, move kibitzes are always sent +regardless of the delay. + +=item B (default: false) + +If true PolyGlot will not understand xboard commands. + +=item B (default: false) + +Indicates whether a PolyGlot book should be used. This has no effect +on the engine own book (which can be controlled with the UCI option +"OwnBook" in the [Engine] section). In particular, it is possible to +use both a PolyGlot book and an engine book. In that case, the engine +book will be used whenever PolyGlot is out of book. Remember that +PolyGlot is unaware of whether the engine is itself using a book or +not. + +=item B (default: false) + +Play Chess960 (also called Fischer Random Chess or FRC), + +=item B (default: 10000) + +Mate score reported to GUI when in xboard mode. + +=item B (default: book.bin) + +The name of the (binary) book file. Note that PolyGlot will look for +it in the directory it was launched from, not in the engine directory. +Of course, full path can be used in which case the current directory +does not matter. + +NOTE: When using PolyGlot with a UCI GUI this parameter can be set +via the UCI option "Polyglot BookFile". + +=item B (default: true) + +Select moves according to their weights in the book. If false the move +with the highest weight is selected. + +=item B (default: false) + +Record learning information in the opening book. Naturally this requires +the opening book to be writable. + +=item B (default: false) + +Run the engine at nice level 5, or "NiceValue" if it set. On some +operating systems it may be necessary to run the engine at lower +priority for it to be responsive to commands from PolyGlot while +searching. + +=item B (default: 5) + +Nice levels go from -20 to 20 with 20 being the lowest priority. +On Unix only root can set negative nice levels. On Windows the standard +Win32 priority levels are mapped in a sensible way to Unix nice levels. + + +=item B (default: -1) + +This a bit vector in which each bit represents the processors that a +process is allowed to run on. This option works only on Windows. + + +=back + +=head2 Work arounds + +Work arounds are identical to options except that they should be used +only when necessary. Their purpose is to try to hide problems with +various software (not just engines). The default value is always +correct for bug-free software. + +IMPORTANT: Any of these work arounds might be removed in future +versions of PolyGlot. You are strongly recommended to contact the +author of faulty software and truly fix the problem. + +PolyGlot supports the following work arounds: + +=over 4 + +=item B (default: 2) + +The default value of 2 corresponds to UCI+. Use 1 to select plain +UCI for engines that have problems with UCI+. + +=item B (default: false) + +PolyGlot now conforms to the documented UCI behaviour: the engine will +be allowed to ponder only if it (the engine) declares the "Ponder" UCI +option. However some engines which can actually ponder do not declare +the option. This work around lets PolyGlot know that they can ponder. + +=item B (default: false) + +When a ponder miss occurs, Polyglot interrupts the engine and +IMMEDIATELY launches a new search. While there should be no problem +with this, some engines seem confused and corrupt their search board. +"SyncStop" forces PolyGlot to wait for the (now useless) ponder search +to finish before launching the new search. + +=item B (default: false) + +Some engines do not specify a promotion piece, e.g. they send "e7e8" +instead of the correct "e7e8q". This work around enables the +incorrect form (and of course promotes into a queen). + +=item B (default: true) + +When true, PolyGlot repeats the last pv string (which also contains +score,depth and time usage) it got from the engine. Some engines +however do not send a new pv string just before sending the move and +the now old pv string might confuse debugtools that parse the winboard +debug files. + + +=back + + +=head2 [Engine] section + +This section contains engine UCI options. PolyGlot does not +understand them, but sends the information to the engine at startup +(converted to UCI form). You can add any UCI option that makes sense +to the engine (not just the common options about hash-table size and +tablebases). + +NOTE: use INI syntax, not UCI. For example "OwnBook = true" is +correct. It will be replaced by PolyGlot with "setoption name OwnBook +value true" at engine startup. + +Standard UCI options are + + Hash + NalimovPath + NalimovCache + OwnBook + +Hidden options like "Ponder" or "UCI_xxx" are automatic +and should not be put in an INI file. + +The other options are engine-specific.
