- --check-table-size arg (=-1)
ignored. just for backward compatibility.
- --ignore-node-counts arg (=1)

- --use-log-linear-probability arg (=0) alternative configuration for
realization probability search (experimental)
- -N [ --num-cpus ] arg (=2)
num cpus for parallel search
- Evaluation options:
- -e [ --eval ] arg (=test)
evaluation function (test or progress
- -p [ --pair-table ] arg
filename for piece pair evaluation function
- --progress-file arg
filename for NewProgress data
- --eval-randomness arg (=0) add random value generated by normal distribution
of a given standard deviation, to evaluation values
- Match options:
- -b [ --black ] arg (=sente)
name of black player
- -w [ --white ] arg (=gote)
name of white player
- -T [ --time-left ] arg (=1500)
total time left
- -B [ --byoyomi ] arg (=0)
seconds for each move (byoyomi)
- -o [ --output-filename ] arg (=gpsshogi.csa)
filename of game record
- -f [ --initial-position ] arg
csa file of initial position
- -R [ --no-table-reuse ]
no effect (preserved only for backward compatibility)
- --save-pv arg (=1)
use pv of previous search results
- -c [ --csa ]
use csa protocol, instead of gnushogi compatible mode
- -a [ --alphabeta ]
use alphabeta, instead of mtd(f)
- -r [ --random ]
random playing
- -s [ --sente ]
computer play first (second if not specified)
- -P [ --opponent-time ]
search while the opponent is thinking
- -x [ --move-with-comment ]
send move with comment (this is a private extension to CSA protocol)
- Opening options:
- -K [ --kisen-file ] arg (=/usr/share/gpsshogi-data/data/kisen/01.kif)
kisen file for opening book (unused unless kisen-id is specified)
- -k [ --kisen-id ] arg (=-1)
id of kisen record for opening book (enabled if positive)
- --csa-file arg
csa file for opening book
- --opening-file arg
file for opening book (used for normal games)
- --no-opening-book
do not use opening book
- -m [ --book-moves ] arg (=30)
maximum depth traced in book
- --enable-determinate-book arg (=0)
if a specified value (N) > 0, a move is selected among the top N weighted moves with a probability propotional to each move's weight (default 0 [disabled])
- --weight-initial-coef arg (=16)
weight coefficient to the top moves, which is used to filter moves only for the initial one.
- --weight-coef arg (=10)
weight coefficient to the top moves, which is used to filter moves except the initial one.
- Other options:
- --benchmark
test search performance
