As MC program often find good shapes, i believe shape is a kind of "average knowledge" of a local problem, like fluid dynamics laws are average knowledge of random move. So including shapes in MC should spare computational effort (and it seems it does for some bots). No simple metric seems possible, except "it works (better) for what we can get" and there we fall back to evaluation of local/global situation: ....c.. ..Oab.. .XXO... choice for O in a, b, c or d ? (all well known shapes) .XOd... Alain. _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
