I don't know why all of a sudden there are problems with this. But I need to take a look when I get a chance. - Don Jason House wrote: Additionally, I noticed the update time is labeled UCT instead of UTC Sent from my iPhone ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/ ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
Re: [computer-go] 9x9 CGOS web updates have stopped
I see the problem - I just looked at the log file. I think I can fix it but right now I don't have the time. Right now I force the server to restart once every 24 hours - so at least it won't more than a day out of date. - Don Jason House wrote: Additionally, I noticed the update time is labeled UCT instead of UTC Sent from my iPhone ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/ ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/

[computer-go] Super ko in random playouts
I now tracked down another super ko bug. I'm curious if anyone has worked out which infinite cyles can occur in random playouts that avoid eye-fills and suicides. Additionally, how do people handle this type of situation in playouts? I believe libego checks game length and assigns "no result" if the game is too long. This certainly seems simple enough to do... A single ko will either be a capture when one side takes it or else it'll be legal to fill the ko when the other side passes from no legal moves left. A double ko can end up with one side owning both ko's, so either the ko will naturally do a capture, or filling a ko will be legal. A triple ko occurred in the attached game. It's 3 ko's between two eyeless groups. Each time a color can move, it owns 1 out of 3 ko's, and has only one legal move option, take the only legal ko (according to simple ko rules) Can any other triple ko situations occur? What about more complex ko situations? I think the triple ko is the only case, but I have not rigorously proven it. superko.sgf Description: application/go-sgf ___ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
RE: [computer-go] Super ko in random playouts
There can be more than 3 kos in a cycle. There are some pathological cases of loops involving captures of two-stone groups, but I've never seen this in a real game. Here are some example odd positions: http://www.cs.cmu.edu/~wjh/go/rules/bestiary.html http://www.goban.demon.co.uk/go/bestiary/molasses_ko.html David > -Original Message- > From: [EMAIL PROTECTED] [mailto:computer-go- > [EMAIL PROTECTED] On Behalf Of Jason House > Sent: Tuesday, July 22, 2008 8:19 PM > To: computer-go@computer-go.org > Subject: [computer-go] Super ko in random playouts > > I now tracked down another super ko bug.
