Nebiyu-MCTS vs TSCP 1-0

Post by Daniel Shawul » Sun Dec 10, 2017 2:06 pm

So I am revisiting MCTS for chess after the awesome AlphaZero news. Note that it worked beautifully for checkers for me a few years ago, but I was never able to get a remotely decent engine with it due to the damn rollouts. It is just very hard to get the tactics right in the rollouts, which will then backpropagate and result in a play that is as dumb as not moving your queen out of threat by a pawn. So now I replaced the rollouts with a shallow tree search of depth 4 and it seems it has improved hugely. It has won against TSCP for the first time using 10 sec/move time control. Note that Nebiyu has only wood evaluation with piece-square tables. It will still probably loose hugely to Nebiyu with nullmove + lmr though. I am testing different depths for the shallow depth search that is a replacement for the NN of alphago. I am using RAVE (rapid action value esimation) in the upper parts fo the tree.

Re: Nebiyu-MCTS vs TSCP 1-0

If you like, please share your code, I'd really like to see a MCTS working implementation. I was never been able to use it with chess and I don't know if it's a MCTS problem or the fact that I implemented it wrongly.

Now put a neural network on top and you got BabyZero :lol:

Very nice! I hope it leads somewhere.

Have you tried an N.E.G.-like algorithm for move selection, which basically would be to just count number of attackers and protectors of each square, and then play with high probability the moves that are expected to gain material based on that (i.e. LxH captures, or when there are more attackers than protectors)? And suppress the probability of non-captures to squares that are not attacked more than protected?

This seems much cheaper to calculate than a 4-ply search, and should quickly find more complex tactics (like pins or batteries) by MCTS and the high efficiency of generating the refutation.

If I understand Daniel correctly then the 4-ply search is only done in the leaf nodes of the MC-tree as a replacement for the neural network. The move selection is done by the UCB rule.

I'm sorry I have been too direct, but I was writing from my smatphone and I had no time to write a longer message.

When I tried to study and implement mcts i didn't found a elegant solution to the problem of mcts tree storage.

Usually in chess we traverse a tree of some million nodes without storing it anywhere. we simply use a depth-first recursive approach without saving the data and using the stack to store temporary imformations, and the engine will oly occupy the memory assigned for the hashtable.

From what I have understood when building mcts tree I have to store it in ram and let it grow while the algorithm evolve in a breadth-first approach.

There is some result I don't know that let us traverse the mcts tree without storing it? or my interpretation is correct and the whole mcts tree shall be saved in ram while we perform the search occupying MB of ram?

I'm sorry if my request offended someone, but my actual interest is to understand this info.

thank you and good luck with your mcts effort :)

Daniel, In place of the piece square tables you would be better served by using two statistics to value the root moves of your shallow search, total number of beta cuts and checkmates for each side. Then return the best material score or in case of materially tied root moves return the score augmented by the statistics.

If you do not believe me then try this simple experiment. With an otherwise material only ab searcher collect only beta cutoffs at the root for the computer. Then play the materially best move and in the case of a material tie play the move with the highest number of beta cutoffs. You will be amazed at the play!
And of course that is just a baseline starting point for a statistical driven search.
Regards,
Mike

That is correct, but I think I am suffering in tactics heavily with this approach too. The problem is that when you have a forced move (e.g. a recapture), and you sample the other moves, obviously wrong ones, moves often enough the real score gets smeared out. That was the problem in the playout part of the MCTS before. In Checkers, captures are forced automatically excluding the non-captures so there is no "smearing problem". So I am gonna have to use the shallow search to bias sampling of moves heavily especially when there is a forced line. I need an efficient search that outputs a score and winning probabilities for each move -- just like the NN -- and then i will use it at the leaves AND in the internal nodes.

Good point H.G. I am gonna try and use something that plays forced moves with high probability. For example, in the following position, it played e2xd4 with the current approach.

[D] rnbqk1nr/pp3ppp/3b4/4p3/3pP3/5N2/PP1PNPPP/R1BQKB1R w KQkq - 0 7

I am gonna have to bias the probability of playing the recapture exd4 with high probability.

The MCTS tree in xml format looks like this after e1xd4 which is played with high probability.
