polyglot perft [-fen fen] [-max-depth depth]
DESCRIPTION
- PolyGlot as adapter and book engine
+ PolyGlot as adapter and book engine
+
PolyGlot is a "UCI adapter". It connects a GUI interface (such as
XBoard, Winboard, Arena or Chessbase) to a UCI chess engine.
NOTE: Not all options are exported, only those that make sense in the
given mode.
- Book making utilities
+ Book making utilities
+
PolyGlot supports the "PolyGlot opening book format". This is the
defacto standard non-proprietary opening book format. It is fully
documented here
Due to the possibility of transpositions this is not a fool proof
method.
- Epd test mode
+ 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
arguments specify when to stop the search in any given position.
- Perft counts
+ 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
however much slower than other more dedicated programs.
When invoked as
- polyglot make-book
+ polyglot make-book
+
PolyGlot supports the following options
-pgn (default: "book.pgn")
When invoked as
- polyglot merge-book
+ polyglot merge-book
+
PolyGlot supports the following options
-in1
When invoked as
- polyglot dump-book
+ polyglot dump-book
+
PolyGlot supports the following options
-bin (default: book.bin)
When invoked as
- polyglot info-book
+ polyglot info-book
+
PolyGlot supports the following options
-bin (default: book.bin)
When invoked as
- polyglot epd-test
+ polyglot epd-test
+
(possibly with a config file as first argument) PolyGlot supports
besides the generic options described above the following additional
options.
When invoked as
- polyglot perft
+ polyglot perft
+
PolyGlot supports the following options
-fen (default: starting position)
"Quoting" other characters in this way has no effect. In particular the
use of '\' as a path separator in windows should normally not affected.
- [PolyGlot] section
+ [PolyGlot] section
+
This section is used by PolyGlot only. The engine is unaware of these
options. The list of available options is detailed below.
move with the highest weight is selected.
BookLearn (default: false)
- Store learning information in the book (which must be writable).
- Currently no engine actually uses this information.
+ This is a noop.
BookDepth (default: 256)
Stop using the book after this number of moves.
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.
+ STFudge (default: 20)
+ PolyGlot will translate "st x" as "go movetime 1000*x-STFudge".
+ The rationale is that in the UCI specification the argument of
+ movetime is defined as the exact search time whereas the argument
+ of the st command is only an upperbound.
+
OnlyWbOptions (default: true)
If true then PolyGlot restricts the options it sends to those that
are potentially useful for WinBoard.
- Work arounds
+ 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).
to the way kibitzing is implemented, KibitzMove is disabled in that
case.
- [Engine] section
+ [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
