That's right. This isn't just a theoretical case: it happens in practice when I play the publicly available mogo on 9x9. If I reach an endgame position where it thinks it's unlikely to win, it goes into self-destruct mode and loses. But it is better than me at the 9x9 endgame, and if it were to lower its sights and wait for me to go wrong it could win (I can verify this after the end of the game by going back to an earlier position and fiddling the komi). One way to think of this is that the computer's opponent model has broken down (ie, its effective assumption that it's playing against another instance of mogo). This also suggests that trying to investigate such a rule using self-play is unlikely to work well. -M- _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
