usiのコマンド一覧

公式 http://www.geocities.jp/shogidokoro/usi.html

expectを使った実行コマンド

usi.sh

#!/usr/bin
expect -c "
spawn bin/release
expect \"info string Failed to open probability.bin.\"
send -- \"usi\n\"
expect \"usiok\"
send -- \"isready\n\"
expect \"readyok\"
send -- \"usinewgame\n\"
send -- \"position sfen l3g2G1/1+B+Rskp3/p1pp4p/4GB1K1/5Gps1/1LPP1P1n1/P+n2PGP1P/9/+s3s1SNL w R2BSN2L2P4 1\n\"
send -- \"go btime 0 wtime 0 byoyomi 30\n\"
expect \"bestmove resign\"
send -- \"exit\n\"
"

phpでsh動かす

<?php
$val_return = shell_exec('sh '.__DIR__."/usi.sh");

定跡選択命令はエラーが出なかったので読み込めてるようだが正常動作はしなかった

send -- \"setoption name BookFile value jouseki_all.bin\n\"
send -- \"setoption name UseBook value true\n\"
