[computer-go] Scaling to 19x19

2006-12-12 Thread Chaslot G (MICC)
Hi David, I have scaled my Monte-Carlo program (Mango) to 19x19. My idea is to bias the UCT distribution including big patterns. This seems to work quite well, and to lead to a much more human-like kind of play then pure Monte Carlo. The patterns were learnt automatically from professional games

Mango passes as soon as the opponent passes two times in a row. Might this lead to bugs in some situations? Anyway this is very nice for playing against humans and GnuGo. Guillaume -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Benjamin Teuber Sent: Tue

I also implemented RAVE in Mango. There was a few points of improvements (around 60 Elo points with gnugo as reference), but as much as in the paper of Gelly and Silver :( (around 250 Elo points if I remember well) It might be that the effect of RAVE depends a lot on the simulation strategy. In
