First thing: Don Dailey is talking about equivalent player to PythonBrown in 9x9 CGOS, not Random. However, for remainder of mail I'm talking mainly about actual random player. I think it has finite, albeit negative rank at 9x9 CGOS. Random statistics against PythonBrown: Result: 348/2511 Win: 13.9% It manages enough often to pass in position where weak opponent has passed and its winning ;-) On 19x19 I think win % would be significantly lower. > Or if it is set at zero ELO all other non random bot will slowly > drift toward +infinity. Actually given *enough* games "fully random including eye filling and passing moves" will win against a pro player. I did find one game where pseudorandom player (==Random at CGOS) wins against GNU Go on 5x5 board. Haven't found one in 7x7 though. I don't know about if this holds true for "non eye filling random player", sometimes it's impossible for it to randomly to play best move ;-) -- Aloril <[EMAIL PROTECTED]> _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
