> As a result of its overconfidence in a win—assuming it will win if the game ends and the points are tallied—KataGo plays a pass move, allowing the adversary to intentionally pass as well, ending the game. (Two consecutive passes end the game in Go.) After that, a point tally begins. As the paper explains, "The adversary gets points for its corner territory (devoid of victim stones) whereas the victim [KataGo] does not receive points for its unsecured territory because of the presence of the adversary's stones."
This isn't how Go scoring works. If there's a dispute in what's considered territory after the two "pass" moves, the way to settle what's actual territory is by continuing play.

Kind of a shame that it is getting so much attention despite the fact that the result is so heavily exaggerated, and the actual accomplishment is pretty minimal.
- Tarsul 4y agoStill, even as a hobby go player i think the broader point that AI usually only works in the constraints that it is designed, bears repeating. Because if journalists/scientists (and us) wouldn't do it, people would maybe start believing the marketing messages about AI too much. But yes, there are better examples (e.g. those delivery robots that don't work in real life conditions).
- halfnormalform 4y agoWhite doesn’t fully control the disputed territory but black controls it even less. I’m rusty but don’t see why the few black stones in the disputed territory mean anything at all—as they aren’t alive. White should get the credit. Also, yes, play should continue. That’s the best answer.
