Re: [computer-go] 9x9
congratulations to mogo on its performance today! it was an excellent result (1-2) versus a professional, Thanks a lot. MoGo has also played some games against other players (including a professional player) and I hope people will accept that we publish the results (they are better than against Catalin :-) ). We have also records of games against very high level players a few weeks before the challenge. Unfortunately, the cluster could not be used during the first game and during the 19x19 game. Catalin said that for the 9x9 games: - mogo was very weak during the first game (the one during which the cluster was replaced by a standard machine); - Catalin had made a mistake in the second game (won by MoGo), and mogo played quite well; - the third game was interesting; Catalin won. Catalin had been warned that it would be more difficult than a few years ago - in particular he was aware of very good results against players of professional level a few weeks ago. He has pointed out that the conditions of the games were ok and that the time was sufficient for working seriously. According to Catalin, the komi 7.5 is too strong; he has been very fair-play, saying that he would perhaps have lost 2 games instead of 1 if the random choice win/black was different (all games were won by white). In 19x19, Catalin won in spite of the 9 handicap stones. Catalin said that MoGo was close to Dan level, as Catalin said it is usually easier for him to win against a 1st Dan player with 9 stones than in that game against MoGo. The cluster was unavailable during the 19x19 game, seemingly due to a trouble in the internet connection. The won game is due in great part to the computer-go mailing list; thanks a lot to all of you. For the two games played by the cluster, it was 32 nodes of 8 cores, 3 GHz as far as I remember. The people providing the hardware can give more details if they want to, I guess they read this mailing list. I also want to point out that someone (probably reading this mailing list) has claimed he has found a solution for winning against mogo, not in the sense of a deterministic sequence but as a kind of situations in which mogo is weak (as the Nakade trouble previously, kindly pointed out by M. Fotland and others). I am unfortunately not able to understand the situations, I'll publish his comment if he can formalize it (well, if he read this mailing list, he will perhaps do it himself :-) ). We have removed most of the openings, because they have been generated before we modify the behavior of mogo in front of Nakade, and the mogo with new nakade-behavior seemingly does not like the openings generated before the nakade-improvement. I guess a very strong improvement will come easily, just by restarting the complete (long and boring) process of generating opening books.

Hey, are you going to stop playing games like http://cgos.boardspace.net/9x9/SGF/2008/03/25/364672.sgf ? MonteGNU had learned that sequence and played from book all the way up to move 31. How is MonteGNU now supposed to be able to win any games against MoGo? ;-) /Gunnar ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/

Re: [computer-go] 9x9
Olivier, and the rest of the Mogo team, Congratulations! I am looking forward to seeing the games. I'm sorry that you weren't able to use the full cluster on the 19x19 game, it would have been interesting to see how much of an improvement would result with such a network of computers.

Re: [computer-go] 9x9 challenge
I attempted to access the games of IaGoChall, and could not; the KGS client beeped at me. Is there a method to review the game records? Thanks!
