I'm not being critical of anything that has already been presented, I just have not seen it myself and I've been pretty busy working on chess so my focus is not currently on this. But I look forward to reading the paper if it's public. (I'm not going to buy the paper.) Don 2010/2/18 Petr Bau

Hello Petr, thx for the diagram. A few question for clarification: Does RAVE mean pachi-with-RAVE? Does RAVE-linkomi mean pachi-with-RAVE-linkomi? Did all three bots (GNUGO, RAVE, RAVE-linkomi) have the same (weak) opponent in these experiments? Who was this "common" opponent? Was this on 19x19?

Ingo, I'm not a proper statistician, but I believe there's a crucial second step that's missing in your analysis of significance. Even if this were the only computer-go test that you personally had ever conducted, we would nevertheless need to take into account all of the other tests being con

Is this 23 cores SMP working on the same tree, or four by 6-cores? I'm running a cluster of four 4-core 2.3 GHz machines, using MPI to share the core of the trees a few times a second. The results between zen-1c, mfgo-16c and pachi-23c are interesting. Zen wins about 60% against many faces
