The *average* length of a 9x9 playout is roughly 100 moves. The max length is much larger. On a 2.2Ghz Athlon64, I get about 10 000 playouts/second, at an average of 100 moves per game this is 1 million updates/second. There are many programs that are much faster. On the same hardware libego would be about 6 million updates/second. 19 x 19 is a bit slower, because strings are bigger on average. > > This also explains that when I read the games MoGo against GNUGo, toward > the > end of the game, GNUGo would play PASS, but MoGo would continue to play at > some very uncommon positions that a normal player would never consider. Pass behaviour has little to do with the playouts themselves. -- GCP _______________________________________________ computer-go mailing list [email protected] http://www.computer-go.org/mailman/listinfo/computer-go/
