Human won by +56.5 points. But Computer was not winner, and Human was not so strong. Computer was my program Aya because of highest rank program that author was in attendance. Human was a winner of dan-kyu certification tournament. And she got 1 dan. So this game was not for examining computer

Section 6 in http://lie.math.brocku.ca/twolf/papers/mono.pdf is about chains with a single eye who's status is ko (the original position does not have a ko-forbidden field) and where passing is one of the best moves of both sides. There also is a position at the end of the paper where the first tw

There was a posting on this list with an example of a (contrived?) situation where sacrificing a pass-alive group is appropriate, in order to win a ko that is more valuable.  Is even #1 "100% admissible"?

During the main search, pass is always one of the moves searched, and if is the best move found, and pass is allowed, it will play a pass. I never avoid searching "pass" in the main search since it gives a good lower bound on the score. If the search returns "pass" too early, I'll play the secon

2006-10-22 Thread Phil G
Does anyone have an example where "pass" is the best move, and not part of the two passes to end the game? I'm trying to determine if passes should ever be considered in a search for the best move, and if so, how to exclude them until it is really necessary.   Thanks,   Phil  _

I'm in a similar situation, I'm trying to identify classes of moves that I can eliminate in an admissible way - which means the move I am throwing out is either not the best move, or there are other equally good moves. I know that pass moves can be the best move in seki situations - and it's non-

How would it affect the game if KO's were handled like in chess? In other words, you may repeat the position in situational superko style, but you have achieved a draw if you do. It seems like it would be an interesting go variant. Presumably one side would always feel compelled to avoid KO (
