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>".
- polyglot -ec engine
+ -ed This is an alias for -pg "EngineDir=<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.
+ -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".
+
+ -lf (default: "polyglot.log")
+ This is an alias for -pg "LogFile=<value>".
+
+ -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.
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.
+ Stop the search if the solution as been found and 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
option = value
...
- Lines starting with "#" are ignored.
+ 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
Show search information during engine pondering. Turning this off
might be better for interactive use in some interfaces.
+ ScoreWhite (default: true)
+ Report score from white's point of view in xboard mode.
+
KibitzMove (default: false)
Whether to kibitz when playing a move.
effect only if "KibitzPV" is selected, move kibitzes are always
sent regardless of the delay.
+ KibitzInterval (default: 0)
+ This is another form of throttling. PolyGlot will usually wait this
+ many seconds before doing the next kibitz.
+
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). The default value is always cor-
- rect for bug-free software.
+ various software (not just engines).
IMPORTANT: Any of these work arounds might be removed in future ver-
sions of PolyGlot. You are strongly recommended to contact the author
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.
+ however do not send a new pv string just before sending the move.
+ In that case the output of PolyGlot would be inconsistent. When
+ RepeatPV is false PolyGlot does not repeat the last pv string. Due
+ to the way kibitzing is implemented, KibitzMove is disabled in that
+ case.
+
+ WbWorkArounds (default: true)
+ 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.
