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 PolyGlot is invoked as an adapter of in epd-test mode it gets its
+ options from a config file and then from the command line. The default
+ config file is "polyglot.ini" but an alternative one may be optionally
+ included as first argument. The config file format is described below.
- When invoked as
+ The following engine options may be specified on the command line.
+
+ -noini
+ Do not use a config file, even if one was specified on the command
+ line.
+
+ -pg The argument is a string of the form <name>=<value>. This option
+ will set the Polyglot option <name> to <value>.
+
+ -uci
+ The argument is a string of the form <name>=<value>. This option
+ will set the engine option <name> to <value>.
+
+ -ec This is an alias for -pg "EngineCommand=<value>".
+
+ -ed This is an alias for -pg "EngineDir=<value>".
+
+ -en This is an alias for -pg "EngineName=<value>"
+
+ -hash
+ This is an alias for -uci "Hash=<value>".
+
+ -log
+ This is an alias for -pg "Log=true".
- polyglot -ec engine
+ -lf (default: "polyglot.log")
+ This is an alias for -pg "LogFile=<value>".
- PolyGlot simply starts "engine" and acts as an adapter. No config file
- is used and thus it is expected that all properties will be set by the
- GUI.
+ -bk This is an alias for -pg "Book=true" -pg "BookFile=<value>".
When invoked as
polyglot epd-test
- (possibly with a config file as first argument) PolyGlot supports the
- following options
+ (possibly with a config file as first argument) PolyGlot supports
+ besides the generic options described above the following additional
+ options.
-max-depth (default: 63)
Unconditionally stop the search when this depth has been reached.
The characters "#" and ";" serve as comment characters.
- NOTE: There can be spaces in option names or values. Do not use
- quotes. Boolean values are written as "true" or "false".
+ By default initial and final white space is stripped from option val-
+ ues. If you want to avoid this, or if you want use one of the comment
+ characters # or ; in option values (such as for NalimovPath), enclose
+ the value in quotes.
[PolyGlot] section
UCI (default: false)
If true PolyGlot will not understand xboard commands.
- Chess960 (default: false)
- Play Chess960 (also called Fischer Random Chess or FRC),
-
MateScore (default: 10000)
Mate score reported to GUI when in xboard mode.
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.
+ BookRandom (default: true)
+ Select moves according to their weights in the book. If false the
+ move with the highest weight is selected.
+
+ BookDepth (default: 256)
+ Stop using the book after this number of moves.
+
+ BookTreshold (default: 5)
+ Do not play moves with a weight (probability) lower than this (in
+ per mil).
UseNice (default: false)
Run the engine at nice level 5, or "NiceValue" if it set. On some
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.
+ SaveSettingsOnExit (default: true)
+ If true then PolyGlot will implement persistence by loading its
+ options from an additional INI file which is specified by the
+ option "SaveFile". At exit PolyGlot will also save its options to
+ this INI file.
+
+ SaveFile (default: <EngineName>.ini)
+ The name of the file from which to take the additional options.
+
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).
- 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:

WbWorkArounds (default: true)
- The intention of this option is to provide work arounds for
- xboard/winboard bugs should they arise. Currently it decapitalizes
- the word Draw in options that contain this word. Some versions of
+ The intention of these options is to provide work arounds for
+ xboard/winboard bugs should they arise. This one decapitalizes the
+ word Draw in options that contain this word. Some versions of
xboard/winboard contain a bug which causes such options to be
interpreted as draw claims by the engine.
Engines that send options with "Draw" in their name are Rybka and
HIARCS.
+ WbWorkArounds2 (default: false)
+ Old version of Winboard clear the engine output window at depth 1.
+ With this work around PG will send info lines at depth >=2. This
+ may or may not improve the display.
+
[Engine] section
This section contains engine UCI options. PolyGlot does not understand
polyglot epd-test -epd test.epd -max-time 420
- The command line for using the UCI engine "fruit" in a GUI which uses
- the xboard protocol.
+ The command line for using the UCI engine "fruit" with 128M hash in
+ xboard with logging enabled.
- polyglot -ec fruit
+ xboard -fcp "polyglot -noini -log -ec fruit -hash 128"
- The equivalent config file:
+ The equivalent config file would be:
[PolyGlot]
EngineCommand = fruit
+ Log = true
[Engine]
+ Hash=128
EXIT STATUS
PolyGlot always returns 0 on exit.
