Thanks! So, is the 100k visits "a lot" for KataGo, or not so much? I understand that without the special anti AI tactics described in the article this would result in "superhuman" play, but what is the reasonable practical limit for the number of such visits?
100K visits is a reasonably large amount. ELF OpenGo beat professional players 20:0 with 80K visits per move[0]. The AlphaGo version that beat Ke Jie likely did 200K visits per move, since the paper indicated that their 1600 simulations per move during training corresponds to 0.4s of think time (with 4 TPUs).
On a good consumer GPU (RTX 3060), I get 1.6K visits per second, so 100K takes about a minute. That makes a game last three to five hours typically.
But the paper emphasizes that even with 10M visits per move (>1h per move), KataGo loses 72% of games against this exploit[1].
