Re: RMO - Randomized Move Order - yet another Lazy SMP derivate

It is only the fixed depth tests that I prefer v4, but there is no reason not to stop the search if one thread reaches the depth limit. It turns out Stockfish can be made stronger by simply repeating a single-threaded search at a given depth a number of times. In fact, it seems a single-threaded se...

I'm quite aware that self-test are often over optimistic, but here :shock: :shock: This concern eval features that are taking into account "next move" possibilities (hanging pieces, forks...

Re: New Tool for Tuning with Skopt

I'm trying it now, using xboard protocol, and I'm not really successful because python-chess seems to be rejecting "usermove=1". Anyone experience this before ? Yes, this is frustrating. I had to implement usermove=0 in sunfish to get it to work with python-chess. Would be great if anyone could sen...

Re: LMP

Late Move Pruning can just as easily be thought of as "Maximally Aggressive Late Move Reduction". Instead of, as in LMR, reducing the remaining depth of a move by some amount depending on how late it is in the move order, you simply reduce the remaining depth to 0, no matter what the remaining depth...
