Big search tuning Most credits for this patch should go to @candirufish. Based on his big search tuning (1M games at 20+0.1s) https://tests.stockfishchess.org/tests/view/61fc7a6ed508ec6a1c9f4b7d with some hand polishing on top of it, which includes : a) correcting trend sigmoid - for some reason original tuning resulted in it being negative. This heuristic was proven to be worth some elo for years so reversing it sign is probably some random artefact; b) remove changes to continuation history based pruning - this heuristic historically was really good at providing green STCs and then failing at LTC miserably if we tried to make it more strict, original tuning was done at short time control and thus it became more strict - which doesn't scale to longer time controls; c) remove changes to improvement - not really indended :). passed STC https://tests.stockfishchess.org/tests/view/6203526e88ae2c84271c2ee2 LLR: 2.94 (-2.94,2.94) <0.00,2.50> Total: 16840 W: 4604 L: 4363 D: 7873 Ptnml(0-2): 82, 1780, 4449, 2033, 76 passed LTC https://tests.stockfishchess.org/tests/view/620376e888ae2c84271c35d4 LLR: 2.96 (-2.94,2.94) <0.50,3.00> Total: 17232 W: 4771 L: 4542 D: 7919 Ptnml(0-2): 14, 1655, 5048, 1886, 13 closes https://github.com/official-stockfish/Stockfish/pull/3926 bench 5030992
