Many Faces was running on a 16 core Xeon (AWS Cluster Compute 8x extra large), using 16 threads, 48 GB of memory. It started well in both handicap games, then fell apart in the endgame. In the main 19x19 tournament, ManyFaces beat Zen once. David -Original Message- From:

That's my impression too. It feels like Zen is slacking his way to the 4 stone wins. 3 stones will be a lot more interesting imo, as we will probably get to see some of the famous zen attacks. It's probably not a good idea to try to recruit well known players for the first 3 stone games. Takemiya

Hi, Aya was running on 10 machines, each has 12 cores @3.3GHz(10x12 =120 cores). I borrowed it from The University of Electro-Communications. Cluster is Root Parallelization with summing up root results each 0.5 sec. Aya uses GTP(Go Text Protocol) to communicate another machines. I tested this

Dear Ingo, Zen's settings are nothing special. Zen19S these days runs on a cluster of four desktop computers, a dual Intel Xeon X5680, Intel i7 3930K, Intel i7 980X and Intel Xeon W3680, all run at 4 GHz. The cluster paralellization code has been, though, improved a little since the match

Hi, Have you looked at Pachi's usage of virtual wins and virtual losses? I had read your paper. That was useful. Thanks. http://pasky.or.cz/go/pachi-tr.pdf I use VirtualLoss N=10 on single machine. I have not tried VirtualWin. I'll try. Winrate vs VirtualLoss N=1 Winrate N 0.457 0 0.532
