I am interested in this improvemnt. Do you have any data to compare the performance of biased playouts with MoGo-style one? (the winning rate against GNU Go, etc) Also, how large and how many are your patterns? -- Yamato _______________________________________________ computer-go mailing list email@example.com http://www.computer-go.org/mailman/listinfo/computer-go/
