Re: [computer-go] The Zen Program
Probably the most original part of Zen is in the playout. I don't think MC simulations must be always fast, so it has a lot of hard-coded Go knowledge. Yamato Hello Are your playouts simple enough so you could publish the exact algorithm in (pseudo) source code? I'm sure many will be interested if you are willing to share it. Regards, Isaac -- Pt!

I need to keep details secret for a while, to retain its commercial value. But I can say that Remi's work was more important than mine. If you don't use minorization-maximization yet, I recommend studying it. -- Yamato ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] The Zen Program
Zen has been registered for this Sunday's tournament on KGS. I hope that other programs will compete. Nick (Repeat of message posted here a few days ago follows) The April 2009 KGS computer Go tournament will be next Sunday, April 5th the Asian evening, European morning and American night, starting at 07:00 UTC/GMT (08:00 BST)) and ending at 13:00 UTC/GMT (14:00 BST). There will be only one division. It will be a 6-round Swiss with 19x19 boards and 29 minutes each of main time. It will use Chinese rules with 7.5 points komi, and a very fast Canadian Overtime, of 25 moves in 20 minutes. There are details at http://www.gokgs.com/tournInfo.jsp?id=447. Registration is now open. To enter, please read and follow the instructions at http://www.weddslist.com/kgs/how/index.html. The rules are given at http://www.weddslist.com/kgs/rules.html. Please send your registration email (with the words KGS Tournament Registration in the title) to me at maproom at gmail dot com (converted to a valid address in the obvious way). -- Nick Weddn...@maproom.co.uk ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] The Zen Program
Thank you for your friendly offer. I think many people on this list will be curious to hear more about what makes Zen such a strong program. Is it similar to Mogo or CrazyStone? Do you use any extra Go knowledge? Which other improvements have you found? Zen is similar to partly MoGo, partly Crazy Stone. It has shape patterns that are generated by minorization-maximization algorithm like Crazy Stone. But they are directly combined with UCT - I don't use progressive widening. Probably the most original part of Zen is in the playout. I don't think MC simulations must be always fast, so it has a lot of hard-coded Go knowledge. I am also interested in hearing your future plans. Will this be a commercial product? Will you participate in the Olympiad and in the next KGS tournament? Will you have a massively parallel version as well? I hope it will be a commercial product but currently I have no specific plans. I don't have plans about a massively parallel version either. Unfortunately I cannot participate in the Olympiad. For KGS, I can. -- Yamato ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] The Zen program
Yamato, It looks like Zen19 doesn't implement handicap stone komi compensation the same way kgs does for Chinese rules. It's the only reason I can think that it lost this game: http://files.gokgs.com/games/2009/3/27/TaPaHka-Zen19.sgf - Andy, aka yoyoma On Thu, Mar 26, 2009 at 5:54 PM, Yamato yamato...@yahoo.co.jp wrote: Rémi Coulom wrote: Martin Mueller wrote: Zen has been getting very impressive results on CGOS.
