Is it really though? A big class of imperfect information games can be modeled by having a record of everything the agent has seen so far. Then it has exactly the same, if not more, information available than a human player in the same position. We know that with equal information AIs can make better decisions than humans (see also, AlphaGo :] ) so at that point the AI could reasonably be expected to achieve superhum…
The difficulty of imperfect information is from cross cutting through information sets and partial observability. With perfect information games like chess or Go, one can solve subgames with guarantees that the equilibrium is the same as for the full game. This is not the case for games like poker, which is why they have been difficult. In addition to that, for n > 2 players, there are no longer theoretical guarantee…

Table 2 is broken, but the rest is much more readable if you're on a phone.

The edits on this comment make it the second best HN comment of all time.
What's the first?
The whole thread is pretty hilarious. In another part of the same thread there is this comment:
we're in a similar space -- http://www.getdropbox.com (and part of the yc summer 07 program) basically, sync and backup done right (but for windows and os x). i had the same frustrations as you with existing solutions.
let me know if it's something you're interested in, or if you want to chat about it sometime.

Given the drawish tendency at top level, among human players, in correspondence chess and also in the TCEC final, I thought that even absolutely perfect play wouldn't score so well against a decent Stockfish setup (which 64 cores and 1 minute per move should be).
So when are they going to apply this to Atari Games or well anything? The next step is they have one AI figure out the rules by making a GAN that imitates player behavior and the other AI be Alpha Go which tweaks the GAN inputs to generate different moves to win. Voila...Almost General Purpose AI that can learn to play any game.
I smell a rat. The paper says: 'AlphaZero achieved within 24 hours a superhuman level of play in the games of chess and shogi' In the first game Stockfish's, 9. Qe1 is one of the strangest moves I've ever seen, which would never be considered by a human, let alone a superhuman. 11. Kh1 also makes little sense, but is not as bad. My Stockfish sees it as losing 0.2 pawns, which makes it highly suspect in such a positio…
Serious question: how does one evaluate the results reproducibility of this paper ? Maybe I'm missing some things but: - Are 1st gen TPUs even accessible ? You have to fill out a form to learn more about those second generation TPUs: https://cloud.google.com/tpu/ - I can't find the source code This does not look like a scientific paper, but a ( very impressive) tech demo.
Does it even qualify as a tech demo if the result only exists in DeepMind's lab?
Two things to note: 1) Alpha Zero beats AlphaGo Zero and AlphaGo Lee and starts tabla rasa 2) "Shogi is a significantly harder game, in terms of computational complexity, than chess (2, 14): it is played on a larger board, and any captured opponent piece changes sides and may subsequently be dropped anywhere on the board. The strongest shogi programs, such as Computer Shogi Association (CSA) world-champion Elmo, have…
Shogi is a fun game, it always feels a little sad that it doesn't get more exposure outside of Japan (and my understanding is that, by and large, in Japan it is considered an "old persons" game) Because captured pieces change sides, there is less of an "endgame" scenario, and as a beginner (like me) it is very easy to put too many captured pieces back into play, which makes it hard to defend everything and essentiall…
