But you still prune moves like filling a one-point eye. We know that there is a pthological case where that indeed is a correct move. So Valkyria will never converge to perfect play even with unlimited CPU power. > But it is really hard to do this right and I still find a lot of bugs of > this kind.

That is a valid point. Not to the theoretical discussion, but in practical everyday life! -H -- Heikki Levanto "In Murphy We Turst" heikki (at) lsd (dot) dk _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
