1) If we're sorting bitmaps into categories (for deciding on the next move), the sorting will be most efficient when we can ask questions with probability of 1/2 of "true" or "false," as in playing a sort of "Twenty Questions." [ These bitmaps wouldn't be necessarily maps of stones on the boar

(no limit hold 'em example) if "no. of hands" can be taken to be "# of distinct 2 card hands, mod suit isomorphism" for the first action, and "no. of hands" is taken to be "# of distinct 3 card hands given the first two cards" for the second action, etc., then it's easy to see that the vast bulk o

Let's recalculate the game space size for poker. For a given hand there are N possible actions. For a given hand and a given action, there are m posssible bets. Then the game space size is N*M*(no. of hands). DL AOL now

I'm not familiar with the tournament poker. So I may be wrong. shouldn't the 'no.hands' in your formular be replaced with a single number that is the probability that oppenent's hand is better than me? If so,it factors out. The only scenarios left to be considered becomes (no. of my actions)^(

Hi Erik, you are right about the parity effect. If you sample game length uniformly from {100,101} then the results are almost everywhere 50%, i.e. no information. With 95% correctly playing agent you get 50.27% correctness for the final result which could be significant enough to be detected

Hi Antti, I had a quick look at your numbers. Maybe I misunderstood something, but at first glance there appears to be a parity effect (an even number of 100% blunder moves always get it right). How do the statistics look if the game length is odd? If it matters, maybe you should sample over a r

Hi, there was some time ago discussion about whether it pays off to improve the quality of an MC play-out agent or not, and how important it is to keep it "balanced", so I performed the following abstract experiment: Assume that we start from a position that is game-theoretic win for Black. I
