Quoting Rémi Coulom <[EMAIL PROTECTED]>:
Regarding the question of null move in Go, I remember that some programmers who tried it in alpha-beta programs did not manage to make it work (Peter MacKenzie comes to mind, maybe others). As Don wrote, the main problem of null move is the depth reduction. It hides long-term threats that the evaluation function might not be able to evaluate.
I used null-moves in my old program Viking which used alpha-beta with lazy MC-Evaluation. It worked in the sense that it searched deeper, but I never observed an increase in playing strength. This might of course mean that the implementation was buggy or could be improved somehow. -- Magnus Persson Berlin, Germany _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
