AyaMC and StoneGrid were the winners of yesterday's KGS bot tournament, both undefeated, with 6/6 and 9/9 wins respectively. My report is at http://www.weddslist.com/kgs/past/39/index.html It is longer than usual, because I found quite a few of the games interesting. Nick -- Nick Wedd

Is it possible to show the board for the round 1 open division game? You refer specifically to a choice made at move 60... Also, the processor description for HBotSVN is incorrect. Rounds 1-6 were through a virtual machine on a box with a 2GHz Intel Core Duo.Rounds 7-9 was running native on

After I review the game, it is hard to say ManyFaces made a mistake at move 60 or around, since the white group at the lower left corner has a flaw. It is a sente for black to settle its F1 group. If white takes two steps to take the ko and A7 group, then black can settle down the F1 black group

[computer-go] Ladders and UCT

2008-06-16 Thread Peter Drake
In Sunday's tournament, Orego lost a game embarrassingly by playing out a lost ladder. I know how to write a ladder checker in general, but I'm not sure how to incorporate such a thing into UCT. What are other people doing? Peter Drake http://www.lclark.edu/~drake/

Thank you for a long, very interesting report, Nick. I found a typo(?), however, about the version of HBotSVN. Jason wrote earlier games were played by r761 but you wrote by r763. -Hideki Nick Wedd: [EMAIL PROTECTED]: In message [EMAIL PROTECTED], Jason House [EMAIL PROTECTED] writes Is it
