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.

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

Yes, even at pv 3, you can continue to use 4 threads

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...

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...

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.
