Why removing montecarlo?
Not well working in some guis and, in general, not fully mature.
Moreover, as demonstrated by the latest tcec, even on a gpu, MCTS is slower than classical alpha/beta.

Re: ShashChess

It can be an option in the future, but on a cpu, it's very slow.

Re: ShashChess

Sorry, and perhaps it is just me (totally low-tech concerning engine performance) but I always have trouble understanding your initial 'explanations'. Wording like this confuses me: "In this case, only one thread (the first not main) uses the MCTS. On a single thread mode, there is no MCTS." So, le...

Re: ShashChess

Thanks, Andrea! What does MCTS checked do? Looking forward to testing regards The MCTS is based on the original Sthepane Nicolet idea ( https://github.com/snicolet/Stockfish/tree/montecarlo/src ). Clearly, we can't on a cpu, use the MCTS on all threads, but, as for the net, we think we can effectiv...

Re: ShashChess

Hi.
Many thanks for the interesting question.
Clearly, Shashin's theory must be adapted to a chess engine.
If you sees the code, the position's nature is etablished at each depth from the previous depth static/quiescent position.
The initial position is "bootstrapped" by the three Shashin's options.
