Hi,
I have just connected Crazy Stone (CS-8-26-10k-1CPU). It uses 10,000
playouts per move, and runs on 1 CPU. It should finish all its games in
less than 5 minutes. In my tests, it scores 41% against GNU Go 3.6 Level
10, and 73.5% against MoGo_release3 at 10k playouts per move (the
playouts of Mogo are about 10% slower than those of Crazy Stone). These
tests were run over 600 games, starting from 300 positions with two
stones located at random (but not on the first two lines), and
alternating colors.
(computational power provided by the Grid5000 project:
https://www.grid5000.fr/mediawiki/index.php/Grid5000:Home
(they ask for advertisement in exchange))
I am a bit surprised that Crazy Stone won so easily against MoGo,
because on the old server, it looked much stronger:

Olivier, do the numbers there indicate the number of playouts? Or is it
playouts per processor? Maybe I messed up something. The log of Mogo
indicates:
10000 simulations(average length:0) done, time used: 2.94 seconds.(
3401.4 games/sec)
So, it looks OK.
I have the feeling that, maybe, MoGo overfits GNU more than Crazy Stone
does. In particular, MoGo's romantic opening style is completely
confusing for GNU, but Crazy Stone has no problem with it. I'll run Mogo
10k against GNU to check.
