Delayed congratulations to AyaMC, winner of last Sunday's KGS bot
Thank you for the tournament and report, Nick! Recently I got +100 Elo from selfplay by adding static bonus in UCB. I used Ikeda's paper method. Effciency of Static Knowledge Bias in Monte-Carlo Tree Search Kokolo Ikeda and Simon Viennot, CG2013 UCB is like this. UCB = w/n + C * sqrt( log(N) / n ); RAVE = Rw/Rn + C * sqrt( log(N*175) / (N*0.48) ); beta = Rn / (Rn + n * (W1 + W2 * Rn)); UCB_RAVE = beta*RAVE + (1-beta)*UCB + G*log(1+gamma)*sqrt( K / (K + n)); n : child nodes w : child wins Rn: child nodes (Rave) Rw: child wins (Rave) N : sum of children's nodes gamma : child gamma from MM C = 0.31 W1 = (1.0 / 0.9) W2 = (1.0 / 20000) K = 600 G = 0.01 Regards, Hiroshi Yamashita _______________________________________________ Computer-go mailing list [email protected] http://dvandva.org/cgi-bin/mailman/listinfo/computer-go
