hello I downloaded CrazyStone-0006-7x7 . The program is a gtp machine. Unfortunately it doesnt know all the commands, in particular it does not know loadsgf nor get/set_random_seed They claim that they can play the best 7x7 game always. They also say they have beaten a professional. So I played a few games. here are a few remarks and I append the games.
1. It plays much better than gnugo, but i think one could write a special fuseki module for 7x7 and then gnugo might play just as well or maybe better ? 2. Counting I am counting "Chinese style" and I get the impression they do the same. Towards the end the program is usually playing meaningless moves, which dont harm if you count "chinese", but if you play japanese rules, they would cost points and CrazyStone would lose. 3. Komi They say the correct komi is nine. If you dont set it explicitly you get 6.5. I thought this might be important for their move statistics, but i dont get that impression. 4. game 1 The first game I played was CrazyStone vs CrazyStone. I dont know, if you get the optimum game for both sides this way. But I played a few variations and could not improve the result. So maybe this is it. However the log tells you that the first 26 moves are book moves. I guess these are moves hard wired in a data base. Afterwards both sides play more or less meaningless moves. 5. game 2 So mow I play Black. I win 10 points. Moreover I play a pretty bad game. 6. game 3 i play again black and win 6 points. 7. game 4 here CrazyStone plays a lot better. (or i play worse) It ends as a draw 8. game 5 Now I play white. I had a hell of a time to find a winning startegy. Eventually I managed to win by 9 points. I do not imagine that I played good moves, the whole thing looks like pure hamete to me. It would be nice to know where black lost the game, but this goes beyond my competence. I can see quite a few doubtful moves, but would not dare to say what it should have played instead. Conclusion The book moves played by CrazyStone seem to be correct. The moves it plays "in thinking mode" rank from very good to bad. The quality of the game varies very much, depending on which random number you get. Nevertheless it seems to avoid the really bad moves which gnugo plays from time to time. There is no doubt this is not " THE BEST " 7x7 game. But there is hope wolfgang game 1 (;FF[4]GM[1] SZ[7] PW[CrazyStone-0006] PB[CrazyStone-0006] DT[2007-05-20] KM[9]RU[Chinese] ;B[dd] ;W[dc] ;B[ec] ;W[cd] ;B[de] ;W[cb] ;B[db] ;W[cc] ;B[ce] ;W[eb] ;B[fb] ;W[da] ;B[fc] ;W[be] ;B[bf] ;W[bd] ;B[af] ;W[fa] ;B[ae] ;W[gb] ;B[ad] ;W[ac] ;B[fe] ;W[ea] ;B[gc] ;W[ga] C[# sofar all book moves] ;B[cf] C[# meaningless] ;W[bb] C[# crazy] ;B[ee] C[# with chinese rules we dont worry] ;W[ef] ;B[gf] ;W[ab] ;B[dg] ;W[ba] ;B[ag] ;W[gd] ;B[bg] ;W[gg] C[# here B resigns ???] ) game 2 (;FF[4]GM[1] SZ[7] PW[CrazyStone-0006] PB[wm] DT[2007-05-20] KM[9]RU[Chinese] ;B[dd] ;W[dc] C[#book move] ;B[ed] ;W[cc] C[#book move] ;B[cd] ;W[ec] C[#book move] ;B[fc] ;W[fb] C[#book move] ;B[bc] ;W[fd] ;B[fe] ;W[gc] ;B[bb] ;W[cb] ;B[ge] ;W[ba] ;B[gd] ;W[bd] ;B[be] ;W[ee] ;B[ef] ;W[gf] ;B[de] ;W[ff] ;B[fc] ;W[ad] ;B[gb] ;W[ac] ;B[eb] C[#should be ae] ;W[ae] ;B[af] ;W[ab] ;B[bf] ;W[cf] C[#should be db] ;B[df] C[#wrong ?] ;W[cg] ;B[da] C[#finally !] ;W[fa] ;B[ea] ;W[db] ;B[ga] ;W[ca] ;B[dg] ;W[fa] ;B[fb] ;W[ag] ;B[bg] ) game 3 (;FF[4]GM[1] SZ[7] PW[CrazyStone-0006] PB[wm] DT[2007-05-20] KM[9]RU[Chinese] ;B[dd] ;W[dc] ;B[ed] ;W[cc] ;B[cd] ;W[ec] ;B[fc] ;W[fb] ;B[bc] ;W[fd] ;B[fe] ;W[gc] ;B[bb] ;W[ff] ;B[ef] ;W[ge] ;B[ee] ;W[gf] ;B[ea] ;W[cb] ;B[ca] ;W[bd] ;B[be] ;W[fg] ;B[eg] ;W[da] C[#problem colour W not found] ;B[db] ;W[df] ;B[da] ;W[bf] ;B[af] ;W[ad] ;B[ae] ;W[ba] C[#problem colour W not found] ;B[aa] ;W[cg] ;B[ce] ;W[cf] ;B[ac] ;W[fa] ;B[ba] ;W[gb] ;B[eb] ;W[fc] ;B[ag] ;W[de] C[#problem colour B not found] ) game 4 (;FF[4]GM[1] SZ[7] PW[CrazyStone-0006] PB[wm] DT[2007-05-20] KM[9]RU[Chinese] ;B[dd] ;W[dc] ;B[ed] ;W[cc] ;B[cd] ;W[ec] ;B[fc] ;W[fb] ;B[bc] ;W[fd] ;B[fe] ;W[bb] ;B[bd] ;W[gc] ;B[ab] ;W[ee] ;B[ef] ;W[ge] ;B[ff] ;W[ba] C[#problem colour W not found] ;B[gf] ;W[gd] ;B[ac] ;W[de] ;B[df] ;W[ce] ;B[be] ;W[cf] ;B[bf] ;W[cb] ;B[aa] ;W[ea] ;B[cg] ;W[ga] C[#problem colour B not found] ;W[de] C[#problem colour B not found] ) game 5 (;FF[4]GM[1] SZ[7] PB[CrazyStone-0006] PW[wm] DT[2007-05-20] KM[9]RU[Chinese] ;B[dd] C[# book move] ;W[ce] ;B[cd] C[# book move] ;W[ec] ;B[ee] ;W[cc] ;B[bd] ;W[ed] ;B[fe] ;W[dc] ;B[bc] ;W[de] ;B[bb] ;W[fd] ;B[df] ;W[cb] ;B[ba] ;W[ge] ;B[gf] ;W[ff] ;B[ef] ;W[gg] ;B[cf] ;W[ca] ;B[fb] ;W[eb] ;B[fg] C[#problem colour B not found] ;W[eg] ;B[gb] ;W[fa] ;B[gd] C[#problem colour B not found] ;W[gc] ;B[ea] C[#problem colour B not found] ;W[da] ;B[ga] C[#problem colour B not found] ;W[fc] ;B[ad] ;W[gf] ;B[cg] ;W[gd] ) _______________________________________________ gnugo-devel mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnugo-devel
