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.

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.

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 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.

Zen has been registered for this Sunday's tournament on KGS.  I hope 
that other programs will compete.

(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

Hi Martin & Rémi, thanks for having interest in my program.
Zen runs on Quad-Core AMD Opteron. I suppose it has nearly the same

Dear Yamato-san,
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?
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?

Thank you

Thanks for reporting it. You are right, I was not aware of the KGS rule.
I think I have fixed the problem now.

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:

Yes, very strong results. Congratulations to Yamato-san for beating

I am curious about hardware. On CGOS, Crazy Stone is running on core2
