From: H.G. Muller Date: Fri, 13 Sep 2013 13:42:27 +0000 (+0200) Subject: Implement undo command X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=6186adc13f7366b1ad78355b2693f2fa8269dd9e;p=bonanza.git Implement undo command This is decoded with the native bonanza commands, and should thus work both in xboard and native mode. It resets the game by faking a 'new' command, and then loads all moves except the last. For this the move list and startup string needed to be remembered. --- diff --git a/makemove.c b/makemove.c index 17713d3..210dfae 100644 --- a/makemove.c +++ b/makemove.c @@ -420,6 +420,7 @@ make_move_root( tree_t * restrict ptree, unsigned int move, int flag ) } root_turn = Flip( root_turn ); + move_list[move_ptr++] = move; // [HGM] undo: remember all moves played in root /* detect checkmate */ if ( check && is_mate( ptree, 1 ) ) { game_status |= flag_mated; } @@ -515,6 +516,7 @@ int CONV unmake_move_root( tree_t * restrict ptree ) ptree->nrep -= 1; game_status &= ~( flag_drawn | flag_mated ); root_turn = Flip(root_turn); + move_ptr--; // [HGM] undo: clip last move off game history for ( i = NUM_UNMAKE-1; i > 0; i -= 1 ) { diff --git a/proce.c b/proce.c index 6538fb9..3de4d5e 100644 --- a/proce.c +++ b/proce.c @@ -90,6 +90,7 @@ static int CONV cmd_move( tree_t * restrict ptree, char **lasts ); static int CONV cmd_new( tree_t * restrict ptree, char **lasts ); static int CONV cmd_read( tree_t * restrict ptree, char **lasts ); static int CONV cmd_resign( tree_t * restrict ptree, char **lasts ); +static int CONV cmd_undo( tree_t * restrict ptree ); // [HGM] undo static int CONV cmd_time( char **lasts ); @@ -122,6 +123,9 @@ procedure( tree_t * restrict ptree ) return proce_cui( ptree ); } +char *start_pos, start_data[512]; // [HGM] undo: for remembering start position +int move_list[1024], move_ptr; + #ifdef XBOARD #define IF(X) else if(!strcmp(command, X)) @@ -200,7 +204,8 @@ Out("# from=%d\n",from); sprintf(line, "%c%c%c%c%s", 'a'+'9'-fromX, '1'+'9'-fromY, 'a'+'9'-toX, '1'+'9'-toY, astr_table_piece[abs(BOARD[from]) + (promo == '+' ? promote : 0)]); } - plyNr++; return 0; + plyNr++; + return 0; } IF("undo") { ; } IF("remove") { ; } @@ -227,6 +232,7 @@ static int CONV proce_cui( tree_t * restrict ptree ) if ( ! strcmp( token, "xboard" ) ) { xboard_mode = 1; game_status |= flag_noprompt; return 1; } } #endif + if ( ! strcmp( token, "undo" ) ) { return cmd_undo( ptree ); } // [HGM] undo if ( is_move( token ) ) { return cmd_usrmove( ptree, token, &last ); } if ( ! strcmp( token, "s" ) ) { return cmd_move_now(); } if ( ! strcmp( token, "beep" ) ) { return cmd_beep( &last); } @@ -496,6 +502,27 @@ cmd_mnjmove( tree_t * restrict ptree, char **lasts, int num_alter ) #endif +static int CONV +cmd_undo( tree_t * restrict ptree ) +{ // [HGM] undo: restart the game, and feed all moves except the last + int i, last = move_ptr; + char *p = start_data; + if( move_ptr <= 0 ) { + str_error = "undo past start of game ignored"; + return -2; + } + + AbortDifficultCommand; + + last--; + cmd_new( ptree, &p ); + for(i=0; i make -f Makefile gcc - -- Intel C++ Compiler on Linux -> make -f Makefile icc - -- Microsoft C/C++ Compiler on Windows -> nmake -f Makefile.vs cl - -- Intel C++ Compiler on Windows -> nmake -f Makefile.vs icl - -The C source codes are written by using ANSI C plus a small number of -new features in ISO C99.

You can find these in "winbin/" -directory. Without the NO_LOGGING option, Bonanza must find "log/" -directory to dump log files. - - -5. Command List ---------------- - -- beep on -- beep off - These commands enable (on) or disable (off) a beep when Bonanza - makes a move. The default is on. - -- book on -- book off - These commands enable (on) or disable (off) to probe the opening - book, "./book.bin". The default is on. - -- book narrow -- book wide - When the command with "narrow" is used, Bonanza selects a book - move from a small set of opening moves. The default is "wide". The - narrowing of the opening moves is useful if you want Bonanza - choose a common opening line. - -- book create - This command creates the opening book file, "./book.bin", by using - numerous experts' games in a single CSA record file, "./book.csa". - It also uses another CSA record file, "book_anti.csa", where you - can register bad moves that may appear in the experts' games at - the last moves in the record file. Here is the example: - - ---------------------------------------- - PI, +, +6978KI, %TORYO - / - PI, +, +6978KI, -8384FU, %TORYO - / - PI, +, +7776FU, -4132KI, %TORYO - / - PI, +, +7776FU, -4132KI, +2726FU, %TORYO - ---------------------------------------- - - This command becomes effective when MINIMUM macro is not defined - in the Makefile. - -- connect 'addr' 'port' 'id' 'passwd' ['ngame'] - This command connects Bonanza to a shogi server by using the CSA - protocol. The first four arguments specify the network address, - port number, user ID, and password, respectively. The last - argument limits a number of games that will be played by Bonanza. - This command becomes effective when CSA_LAN macro is defined in - the Makefile. - -- dfpn go - Bonanza does DFPN search at a current position. - -- dfpn hash 'num' - This command is used to initialize the transposition table of - DFPN search and set the size of the table to 2^'num'. This - command becomes effective when DFPN macro is defined in the - Makefile. - -- dfpn connect 'hostname' 'port#' 'ID' - This command is used to connect to the server script - dfpn_server.pl as a worker. This command becomes effective when - DFPN macro is defined in the Makefile. - -- dfpn_client 'hostname' 'port#' - This command is used to connect to the server script - dfpn_server.pl as a client. With this, a root and its child - posittions are examined by the DFPN worker(s). This command - becomes effective when DFPN_CLIENT macro is defined in the - Makefile. - -- display ['num'] - This command prints the shogi board. If you want to flip the - board, set 'num' to 2. If not, set it to 1. - -- s - Bonanza makes a prompt reply while thinking as soon as this - command is used. - -- hash 'num' - This command is used to initialize the transposition table and - set the size of the table to 2^'num'. - -- hash learn create - This command is used to make a zero-filled position-lerning - database, "hash.bin". This command becomes effective when MINIMUM - macro is not defined in the Makefile. - -- hash learn on -- hash learn off - These commands enable (on) or disable (off) the position learning. - The default is on. - -- learn 'str' 'steps' ['games' ['iterations' ['num1' ['num2']]]] - This command optimizes a feature vector of the static evaluation - function by using numorous experts' games in a single CSA record - file, "./records.csa". If you want to use a zero-filled vector as - an initial guess of the optimization procedure, set 'str' to - "ini". If not, set it to "no-ini". The third argument 'games' is a - number of games to be read from the record file. If the third - argument is negative or omitted, all games are read from the file. - - The learning method iterates a set of procedures, and the number - of iteration can be limited by the fourth argument. It continues - as long as the argument is negative. The procedures consist of two - parts. The first part reads the record file and creates principal - variations by using 'num1' threads. The default value of 'num1' is - 1. The second part renews the feature vector 'steps' times by using - 'num2' threads in accord with the principal variations. The default - value of 'steps' and 'num2' is 1. Note that each thread in the - second procedure uses about 500MByte of the main memory. The two - arguments 'num1' and 'num2' become effective when TLP macro is - defined in the Makefile. After the procedures, the optimized - vector is saved in "./fv.bin". This command become effective when - MINIMUM macro is not defined in the Makefile. - -- limit depth 'num' - This command is used to specify a depth, 'num', at which Bonanza - ends the iterative deepening search. - -- limit nodes 'num' - When this command is used, Bonanza stops thinking after searched - nodes reach to 'num'. - -- limit time 'minute' 'second' ['depth'] - This command limits thinking time of Bonanza. It tries to make - each move by consuming the time 'minute'. When the time is spent - all, it makes each move in 'second'. The last argument 'depth' can - be used if you want Bonanza to stop thinking after the iterative - deepening searches reach sufficient depth. - -- limit time extendable -- limit time strict - The command, "limit time extendable", allows Bonanza to think - longer than the time limited by the previous command if it wishes - to. The default is "strict". - -- mnj 'sd' 'seed' 'addr' 'port' 'id' 'factor' 'stable_depth' - This command connects Bonanza to the majority or parallel server in - src/server/. The first two integers specify the standard - deviation and initial seed of pseudo-random numbers which are - added to the static evaluation function. Experiments suggested - that an appropriate value for the standard deviation is 15. Note - that all clients should use different seeds. The following three - arguments are network address, port number, user ID, - respectively. You can specify factor as a voting weight. Also - stable_depth is useful to detect opening positions. Here, when - Bonanza reaches the specified depth, then this is reported to the - server to reduce thinking time. This command becomes effective - when MNJ_LAN macro is defined in the Makefile. - -- move ['str'] - Bonanza makes a move of 'str'. If the argument is omitted, Bonanza - thinks of its next move by itself. - -- mpv num 'nroot' -- mpv width 'threshold' - These commands control the number of root moves, 'nroot', to - constitute principal variations. The default number is 1. A root - move that yields a smaller value than the best value by 'threshold' - is neglected. The default threshold is about 200. These commands - become effective when MPV macro is defined in the Makefile. - -- new ['str'] - This command initializes the shogi board. The argument 'str' - controls an initial configuration of the board. If you want to - play a no-handicapped game, set 'str' to "PI" and this is the - default value. In a handicapped game, specify squares and pieces - to drop, e.g. "new PI82HI22KA" or "new PI19KY". - -- peek on -- peek off - The command "peek on (off)" enables (disables) peeks at a buffer - of the standard input file while Bonanza is thinking. The default - is on. This command is useful when you want to process a set of - commands as "> ./bonanza.exe < infile". - -- ping - Prompt Bonanza to print "pong". - -- ponder on -- ponder off - The command "ponder on (off)" enables (disables) thinks on the - opponent's time. The default is on. - -- problem ['num'] - This command is used to solve problems in "./problem.csa". Here - is an example of the problem file. - - ----------------------------- - $ANSWER:+0024FU - P1-KY-KE-OU-KI * * * * -KY - P2 * * * * * -KI * * * - P3 * * -FU-GI-FU * -KE * -KA - P4-FU * * -FU-GI-FU-HI * -FU - P5 * * * * * * * -FU+KY - P6+FU+KA+FU+FU+GI+FU+KI * * - P7 * +FU * * +FU * * * * - P8 * +OU+KI+GI * * +HI * * - P9+KY+KE * * * * * +KE * - P+00FU00FU - P-00FU00FU00FU - + - / - $ANSWER:+0087KY:+0088KY - P1-OU-KE * * * * * +GI * - P2-KY-KI * * * * * * * - P3-FU-HI * -KI * * -GI * * - P4 * * -KE * * * * * -FU - P5 * +GI * -FU-FU-FU-FU-FU * - P6+FU+HI-FU * * * * * * - P7 * * * +FU * * * * +FU - P8 * * +OU+KI+KI * * * * - P9+KY+KE * * * * * +KE+KY - P+00KA00GI00KY00FU00FU - P-00KA00FU00FU00FU00FU00FU - + - ----------------------------- - - The argument 'num' specifies the number of problems to solve. - -- quit - The quit command and EOF character will exit Bonanza. - -- read 'filename' [(t|nil) ['num']] - This command is used to read a CSA record 'filename' up to 'num' - moves. Set the second argument to "nil" when you want to ignore - time information in the record. The default value is "t". Bonanza - reads all move sequence if the last argument is neglected. If - 'filename' is ".", the command reads an ongoing game from the - initial position. - -- resign - Use this command when you resign a game. - -- resign 'num' - This command specifies the threshold to resign. 'num' is a value - of the threshold. The default is around 1000. - -- stress on -- stress off - When the command "stress on" is used, last-move shown in shogi - board is stressed. The default is on. - -- time remain 'num1' 'num2' - This command tells Bonanza the remaining time. 'num1' ('num2') is - the remaining time of black (white) in seconds. - -- time response 'num' - This command specifies a margin to control time. The time margin - saves Bonanza from time up due to TCP/IP communication to a server - program, sudden disc access, or imperfection of time control of - Bonanza. 'num' is the time margin in milli-second. The default - value is 200. - -- tlp 'num' - This command controls the number of threads to be created when - Bonana considers a move to make. The command becomes effective - when TLP macro is defined in the Makefile. 'num' is the number of - threads. The default value is 1. - -- # - A line beginning with # causes all characters on that line - to be ignored. - -- [move command] - A move command consists of four digits followed by two - capital alphabets, e.g. 7776FU. The first two digits - are a starting square and the last two are a target square. The - starting square is "OO" if the move is a dorp, e.g. 0087FU. The - following two alphabets specify a piece type as the following, - - FU - pawn (Fuhyo) TO - promoted pawn (Tokin) - KY - lance (Kyousha) NY - promoted lance (Narikyo) - KE - knight (Keima) NK - promoted knight (Narikei) - GI - silver general (Ginsho) NG - promoted silver (Narigin) - KI - gold general (Kinsyo) - KA - Bishop (Kakugyo) UM - Dragon horse (Ryuma) - HI - Rook (Hisha) RY - Dragon king (Ryuo) - OU - King (Osho) - - Here, words in parentheses are romanization of Japanese words. +---------------------------------------------------------------------- + Bonanza 6.0 - Client Source Code + Kunihito Hoki, May 2011 +---------------------------------------------------------------------- + + +1. Introduction +---------------- + +Bonanza is a state-of-the art computer shogi engine which runs on +Windows and Linux machines, and this directory contains a +platform-independent source code. + +This source code is distributed with a hope that it will be useful in +addition to the main part of the shogi engine. This program includes +many useful functions such as manipulating a shogi board, reading and +writing a CSA record file, speaking of a CSA protocol with a socket +communication, and controlling time, and etc.. I believe this program +can be a good starting point if you are interested in making shogi +programs. + +One main feature of this program is that it employs a brute-force +search method together with bitboard techniques as many chess programs +do. Another notable feature is a machine learning of shogi evaluation +functions. The details of the learning algorithm (aka Bonanza method) +were already presented [1], and this source code provides an example +of implementation of the learning method. + +I admit that some parts of the source code are cryptic, e.g. codes in +"mate1ply.c". I hope that I will have some time to make a quality +documentation and comments on the program code, or someone else could +decrypt my program and provide a documentation. + +Any comments or suggestions are welcome [2]. + +[1] K. Hoki, "Optimal control of minimax search results to learn + positional evaluation", Game Programming Workshop, Hakone, Japan + 2008. + +[2] Contact to "bonanza_query [at] hotmail.com". + + +2. Legal Notices +----------------- + +This program is protected by copyright. Without a specific +permission, any means of commercial applications are prohibited. +Furthermore, this program is distributed without any warranty. +Within these limits, you can use, redistribute, and/or modify it. + + +3. Change Logs +--------------- + +Version 6.0 + +Search() function is modified to ignore moves which receive negative +values from Static Exchange Evaluation (SEE) at frontier and +pre-frontier nodes. Self-play experiments showed that this modification +makes Bonanza slightly stronger. Similar results were also observed in +experiments using a shogi program YSS, +http://www32.ocn.ne.jp/~yss/horizon.txt. Moreover, the branch cut by +means of SEE at frontier nodes can also be found in a chess program, +Stockfish. + +Now Bonanza does Late Move Reduction (LMR) at root nodes, and recursive +iterative deepening more often. Self-play experiments showed that these +modifications make Bonanza slightly stronger. + +DFPN searcher is added to the set of Bonanza source codes (dfpn.c, +dfpn.h, and dfpnhash.c). You can use the searcher by using 'dfpn' +command with a compile option -DDFPN turned on. To make use of the DFPN +searcher in ordinary search, use 'dfpn_client' command with a compile +option -DDFPN_CLIENT turned on. To provide a proper service to the DFPN +client, you also need to use a server script 'src/server/dfpn_server.pl' +with one or more DFPN worker(s) connected with 'dfpn connect' command. +I am thankful to Dr. A. Nagai for his kind and fruitful advice. + +Now Bonanza can be a client of parallel searches using cluster computing +environment with mnj command. 'src/server/parallel_server.pl' is a +server script of root-node parallelizations, and the server can be a +client of majority voting cluster computation. + +Some techniques which increase computational efficiency of Bonanza are +reported by E. Ito, http://aleag.cocolog-nifty.com/. In his website, +two ideas are shown, i.e., (i) speed up of the computation of the static +evaluation function, and (2) use of SSE instructions of Intel processors +for bitboard operations. By adopting his ideas to Bonanza, NPS value +nearly doubled. This is amazing. To use SSE instructions, specify -DSSE2 +or -DSSE4 compiler option. I am thankful to Mr. E. Ito for his kind and +fruitful advice. + +-DINANIWA_SHIFT compilation flag is supplied to enable an Inaniwa-strategy detection + +There are many other modifications and bug fixes. + + +Feliz 0.0 + +- Some results from Y. Sato's experiments with Bonanza inspired me + to use the history table in LMR in Shogi, as Fruit did in chess. By + doing so, some improvement in performance of the tree search is + made. + +- From private communications with Yaneurao, it turned out that the + 3-ply-mate detections in 'mate3.c' can search game trees more + efficiently by using several heuristic pruning techniques. Now + 'mate3.c' adopts some of these techniques. + +- E. Ito kindly reported two bugs in the source codes. One is in + hash_store(), and the other is in ehash_probe() and + ehash_store(). Now these are fixed. + +- The structure of history table is modified from 'square-to' and + 'square-from' method to an exact match method by using the perfect + hash technique. The hash function of moves in 'phash.c' is generated + by codes at http://burtleburtle.net/bob/hash/perfect.html. + +- A command 'mnj' is added to connect to the cluster-computing server + in src/cluster/. + +- In client_next_game(), the way of dealing with REJECT message from a + CSA Shogi server is revised. Now Bonanza connects to the server again + when the game is rejected by an opponent. + + +Version 4.1.3 +- The owner of 'LS3600 Blog Webpage' pointed out that there were two + serious bugs. Thank you very much! According to his indication, + is_hand_eq_supe() in 'utility.c' and read_CSA_line() in 'csa.c' are + revised. +- In MPV code in 'searchr.c', a test of 'root_abort' flag had been + forgotten. Now the flag is tested after every call of search(). +- 'lan.txt' is added to 'src/executable/' directory. This is an + example of an input sequence to connect to CSA Shogi server. +- 'book.bin' now has smaller moves and positions than previous one does. + Also, 'book_anti.csa' is added to 'src/executable/' directory. This + is an example of bad moves which apear in records of human experts. +- 'Legal Notices' in this document is corrected. + +Version 4.1.2 +- In 'Makefile' and 'Makefile.vs', targets which require profile-guided + optimization are removed. Furthermore, an option, which controls + optimization, has been reverted from the aggressive flag, -O3, to a + moderate one, '-O2'. These modifications were necessary for avoiding + abnormal terminations of the program. +- In 'ini.c', the attribute of POSIX thread in a global-variable + 'pthread_attr' is set to 'detach-state'. Because threads will never + join with any other threads in this program, the thread should be + created in the detached state to free system resources. +- In 'ini.c', the default size of the transposition table is lifted + from 12MByte to 48MByte. +- In 'iterate.c", probing the opening book is avoided when the move + history of a current game has repetitions. +- In 'shogi.h', the margins of futility pruning are increased in + accord with new positional evaluation of the feature vector in + 'fv.bin'. +- The quality of an opening book, 'winbin/book.bin', has been improved + at the expense of quantity. + +Version 4.1.0 and 4.1.1 (26 Apr 2009) +- In 'Makefile' and 'Makefile.vs', some options of Intel C compiler + are modified. Here, agressive optimization '-O3' is substituted for + the default '-O2', pthreads support '-pthread' is substituted for + '-lpthread', and an obsolete '-static-libcxx' is removed. +- In 'Makefile', the conformance of GNU C and Intel C compilers are + set to GNU extensions of ISO C99 by setting '-std=gnu99' because a + POSIX function 'strtok_r()' is not in the C99 standard library. +- In 'Makefile', targets for GNU C with gprof and profile-guided + optimization of GNU C are removed. +- In 'shogi.h', inline assemblies and intrinsics are used on x86-64 as + well as x86. To detect the targets, pre-defined macros '__i386__' + and '__x86_64__' are examined. +- In 'evaluate.c', the evaluation function looks up the table + 'stand_pat[ply]' to see if the position have been evaluated since + the previous move is made by 'make_move_[bw]()' functions. Also, the + evaluation function probes the hash table 'ehash_tbl[]' to avoid + re-evaluation of the same position. +- In 'io.c', an immediate value 0 is substituted for 'fileno(stdin)' + because the POSIX function 'fileno()' is not part of ANSI C. POSIX + requires that the file descriptor associated with 'stdin' be 0. +- In 'iterate.c', a criterion for aging of transposition-table, i.e., + increment of a global variable 'trans_table_age', is lifted from 7% + to 9% of saturation ratio of the table. +- In 'learn1.c', the macro 'SEARCH_DEPTH' is set to 2. The macro + specifies the depth threashold of searches for finding all of + principle variations of positions in a set of games. +- In 'learn1.c', a step size of increment/decrement of feature vectors + is fixed to 1 in 'learn_parse2()' function. +- In 'hash.c', when a node can be pruned by using a hash value based on + futility pruning, a return value of the node is set to beta. +- In 'rand.c', some codes of initialization of PRNG variables are + moved to 'ini_genrand()' from 'ini()' function. +- In 'sckt.c', a function 'send_crlf()' is removed. +- In 'search.c', now 'search()' calls 'search_quies()' and returns if + a search depth reaches a threashold. So that we can call 'search()' + function anytime, and this makes source codes simple. +- In 'search.c', the static evaluation value is evaluated and used to + see if the late-move reduction is applicable or not. The evaluation + value is also used by the futility pruning. +- In 'search.c', the futility pruning is not applied if the node is in + check or the move is a check. +- In 'search.c', now Bonanza sends the keep-alive command '0x0a' to + the server in 'detect_signals()'. +- In 'time.c', 'set_seach_limit_time()' is simplified. +- In 'time.c', the second argument of 'gettimeofday()' is set to 'NULL'. + +Version 4.0.4 (2 Feb 2009) +- An error of GCC inline assembly for spinlock in "thread.c" is fixed. +- In Windows OS, Bonanza now opens all streams with file sharing by + using "_SH_DENYNO" constant in "io.c". +- GCC built-in functions are substituted for GCC inline assemblies for + bit-scan operations in "bitop.h". Furthermore, "bitop.h" is removed, + and some of macros in the header are integrated into "shogi.h". + +Version 4.0.3 (Jan 2008) + + +4.

Therefore, I think this can be easily built +in many platforms without much effort. + +It may be necessary to define some macros in Makefile or +Makefile.vs. The macros are: + +- NDEBUG (DEBUG) builds release (debug) version of Bonanza + +- MINIMUM disables some auxiliary functions that are not + necessary to play a game, e.g., book composition + and optimization of evaluation functions + +- TLP enables thread-level parallel search + +- MPV enables multi-PV search + +- CSA_LAN enables Bonanza to communicate by CSA Shogi TCP/IP + protcol + +- DEKUNOBOU enables dekunobou interface (available only for + Windows) + +- CSASHOGI builds an engine for CSA Shogi (available only for + Windows) + +- NO_LOGGING suppresses dumping log files + +- HAVE_SSE2 use SSE2 instructions for speed + +- HAVE_SSE4 use SSE2 and SSE4.1 instructions for speed + +- MNJ_LAN enables a client-mode of cluster searches + +- INANIWA_SHIFT enables an Inaniwa strategy detection + +- DFPN build the DFPN worker of mate-problems server + +- DFPN_CLIENT enables the client-mode of mate-problem server + + +Bonanza is an application that does not provide graphical user +interface. If you could build "bonanza.exe" properly without CSASHOGI +macro, it shows a prompt "Black 1>" when you execute it at a computer +console. + +Bonanza uses three binary files: a feature vector of static evaluation +function "fv.bin", an opening book "book.bin", and a +position-learning database "hash.bin". You can find these in "winbin/" +directory. Without the NO_LOGGING option, Bonanza must find "log/" +directory to dump log files. + + +5. Command List +--------------- + +- beep on +- beep off + These commands enable (on) or disable (off) a beep when Bonanza + makes a move. The default is on. + +- book on +- book off + These commands enable (on) or disable (off) to probe the opening + book, "./book.bin". The default is on. + +- book narrow +- book wide + When the command with "narrow" is used, Bonanza selects a book + move from a small set of opening moves. The default is "wide". The + narrowing of the opening moves is useful if you want Bonanza + choose a common opening line. + +- book create + This command creates the opening book file, "./book.bin", by using + numerous experts' games in a single CSA record file, "./book.csa". + It also uses another CSA record file, "book_anti.csa", where you + can register bad moves that may appear in the experts' games at + the last moves in the record file. Here is the example: + + ---------------------------------------- + PI, +, +6978KI, %TORYO + / + PI, +, +6978KI, -8384FU, %TORYO + / + PI, +, +7776FU, -4132KI, %TORYO + / + PI, +, +7776FU, -4132KI, +2726FU, %TORYO + ---------------------------------------- + + This command becomes effective when MINIMUM macro is not defined + in the Makefile. + +- connect 'addr' 'port' 'id' 'passwd' ['ngame'] + This command connects Bonanza to a shogi server by using the CSA + protocol. The first four arguments specify the network address, + port number, user ID, and password, respectively. The last + argument limits a number of games that will be played by Bonanza. + This command becomes effective when CSA_LAN macro is defined in + the Makefile. + +- dfpn go + Bonanza does DFPN search at a current position. + +- dfpn hash 'num' + This command is used to initialize the transposition table of + DFPN search and set the size of the table to 2^'num'. This + command becomes effective when DFPN macro is defined in the + Makefile. + +- dfpn connect 'hostname' 'port#' 'ID' + This command is used to connect to the server script + dfpn_server.pl as a worker. This command becomes effective when + DFPN macro is defined in the Makefile. + +- dfpn_client 'hostname' 'port#' + This command is used to connect to the server script + dfpn_server.pl as a client. With this, a root and its child + posittions are examined by the DFPN worker(s). This command + becomes effective when DFPN_CLIENT macro is defined in the + Makefile. + +- display ['num'] + This command prints the shogi board. If you want to flip the + board, set 'num' to 2. If not, set it to 1. + +- s + Bonanza makes a prompt reply while thinking as soon as this + command is used. + +- hash 'num' + This command is used to initialize the transposition table and + set the size of the table to 2^'num'. + +- hash learn create + This command is used to make a zero-filled position-lerning + database, "hash.bin". This command becomes effective when MINIMUM + macro is not defined in the Makefile. + +- hash learn on +- hash learn off + These commands enable (on) or disable (off) the position learning. + The default is on. + +- learn 'str' 'steps' ['games' ['iterations' ['num1' ['num2']]]] + This command optimizes a feature vector of the static evaluation + function by using numorous experts' games in a single CSA record + file, "./records.csa". If you want to use a zero-filled vector as + an initial guess of the optimization procedure, set 'str' to + "ini". If not, set it to "no-ini". The third argument 'games' is a + number of games to be read from the record file. If the third + argument is negative or omitted, all games are read from the file. + + The learning method iterates a set of procedures, and the number + of iteration can be limited by the fourth argument. It continues + as long as the argument is negative. The procedures consist of two + parts. The first part reads the record file and creates principal + variations by using 'num1' threads. The default value of 'num1' is + 1. The second part renews the feature vector 'steps' times by using + 'num2' threads in accord with the principal variations. The default + value of 'steps' and 'num2' is 1. Note that each thread in the + second procedure uses about 500MByte of the main memory. The two + arguments 'num1' and 'num2' become effective when TLP macro is + defined in the Makefile. After the procedures, the optimized + vector is saved in "./fv.bin". This command become effective when + MINIMUM macro is not defined in the Makefile. + +- limit depth 'num' + This command is used to specify a depth, 'num', at which Bonanza + ends the iterative deepening search. + +- limit nodes 'num' + When this command is used, Bonanza stops thinking after searched + nodes reach to 'num'. + +- limit time 'minute' 'second' ['depth'] + This command limits thinking time of Bonanza. It tries to make + each move by consuming the time 'minute'. When the time is spent + all, it makes each move in 'second'. The last argument 'depth' can + be used if you want Bonanza to stop thinking after the iterative + deepening searches reach sufficient depth. + +- limit time extendable +- limit time strict + The command, "limit time extendable", allows Bonanza to think + longer than the time limited by the previous command if it wishes + to. The default is "strict". + +- mnj 'sd' 'seed' 'addr' 'port' 'id' 'factor' 'stable_depth' + This command connects Bonanza to the majority or parallel server in + src/server/. The first two integers specify the standard + deviation and initial seed of pseudo-random numbers which are + added to the static evaluation function. Experiments suggested + that an appropriate value for the standard deviation is 15. Note + that all clients should use different seeds. The following three + arguments are network address, port number, user ID, + respectively. You can specify factor as a voting weight. Also + stable_depth is useful to detect opening positions. Here, when + Bonanza reaches the specified depth, then this is reported to the + server to reduce thinking time. This command becomes effective + when MNJ_LAN macro is defined in the Makefile. + +- move ['str'] + Bonanza makes a move of 'str'. If the argument is omitted, Bonanza + thinks of its next move by itself. + +- mpv num 'nroot' +- mpv width 'threshold' + These commands control the number of root moves, 'nroot', to + constitute principal variations. The default number is 1. A root + move that yields a smaller value than the best value by 'threshold' + is neglected. The default threshold is about 200. These commands + become effective when MPV macro is defined in the Makefile. + +- new ['str'] + This command initializes the shogi board. The argument 'str' + controls an initial configuration of the board. If you want to + play a no-handicapped game, set 'str' to "PI" and this is the + default value. In a handicapped game, specify squares and pieces + to drop, e.g. "new PI82HI22KA" or "new PI19KY". + +- peek on +- peek off + The command "peek on (off)" enables (disables) peeks at a buffer + of the standard input file while Bonanza is thinking. The default + is on. This command is useful when you want to process a set of + commands as "> ./bonanza.exe < infile". + +- ping + Prompt Bonanza to print "pong". + +- ponder on +- ponder off + The command "ponder on (off)" enables (disables) thinks on the + opponent's time. The default is on. + +- problem ['num'] + This command is used to solve problems in "./problem.csa". Here + is an example of the problem file. + + ----------------------------- + $ANSWER:+0024FU + P1-KY-KE-OU-KI * * * * -KY + P2 * * * * * -KI * * * + P3 * * -FU-GI-FU * -KE * -KA + P4-FU * * -FU-GI-FU-HI * -FU + P5 * * * * * * * -FU+KY + P6+FU+KA+FU+FU+GI+FU+KI * * + P7 * +FU * * +FU * * * * + P8 * +OU+KI+GI * * +HI * * + P9+KY+KE * * * * * +KE * + P+00FU00FU + P-00FU00FU00FU + + + / + $ANSWER:+0087KY:+0088KY + P1-OU-KE * * * * * +GI * + P2-KY-KI * * * * * * * + P3-FU-HI * -KI * * -GI * * + P4 * * -KE * * * * * -FU + P5 * +GI * -FU-FU-FU-FU-FU * + P6+FU+HI-FU * * * * * * + P7 * * * +FU * * * * +FU + P8 * * +OU+KI+KI * * * * + P9+KY+KE * * * * * +KE+KY + P+00KA00GI00KY00FU00FU + P-00KA00FU00FU00FU00FU00FU + + + ----------------------------- + + The argument 'num' specifies the number of problems to solve. + +- quit + The quit command and EOF character will exit Bonanza. + +- read 'filename' [(t|nil) ['num']] + This command is used to read a CSA record 'filename' up to 'num' + moves. Set the second argument to "nil" when you want to ignore + time information in the record. The default value is "t". Bonanza + reads all move sequence if the last argument is neglected. If + 'filename' is ".", the command reads an ongoing game from the + initial position. + +- resign + Use this command when you resign a game. + +- resign 'num' + This command specifies the threshold to resign. 'num' is a value + of the threshold. The default is around 1000. + +- stress on +- stress off + When the command "stress on" is used, last-move shown in shogi + board is stressed. The default is on. + +- time remain 'num1' 'num2' + This command tells Bonanza the remaining time. 'num1' ('num2') is + the remaining time of black (white) in seconds. + +- time response 'num' + This command specifies a margin to control time. The time margin + saves Bonanza from time up due to TCP/IP communication to a server + program, sudden disc access, or imperfection of time control of + Bonanza. 'num' is the time margin in milli-second. The default + value is 200. + +- tlp 'num' + This command controls the number of threads to be created when + Bonana considers a move to make. The command becomes effective + when TLP macro is defined in the Makefile. 'num' is the number of + threads. The default value is 1. + +- undo + This command causes the latest move to be taken back. + +- # + A line beginning with # causes all characters on that line + to be ignored. + +- [move command] + A move command consists of four digits followed by two + capital alphabets, e.g. 7776FU. The first two digits + are a starting square and the last two are a target square. The + starting square is "OO" if the move is a dorp, e.g. 0087FU. The + following two alphabets specify a piece type as the following, + + FU - pawn (Fuhyo) TO - promoted pawn (Tokin) + KY - lance (Kyousha) NY - promoted lance (Narikyo) + KE - knight (Keima) NK - promoted knight (Narikei) + GI - silver general (Ginsho) NG - promoted silver (Narigin) + KI - gold general (Kinsyo) + KA - Bishop (Kakugyo) UM - Dragon horse (Ryuma) + HI - Rook (Hisha) RY - Dragon king (Ryuo) + OU - King (Osho) + + Here, words in parentheses are romanization of Japanese words. + diff --git a/shogi.h b/shogi.h index 23a7329..62800dd 100644 --- a/shogi.h +++ b/shogi.h @@ -956,6 +956,7 @@ extern const int aikkp_hand[8]; extern const char ach_turn[2]; extern const unsigned char aifile[ nsquare ]; extern const unsigned char airank[ nsquare ]; +extern int move_list[], move_ptr; // [HGM] undo: game history (used in proce.c and makemove.c) #if defined(DFPN_CLIENT) # define DFPN_CLIENT_SIZE_SIGNATURE 64
