Date: Sun Dec 19 08:03:41 2021 +0100 Timestamp: 1639897421 Reintroduce futility pruning for captures This is a reintroduction of an idea that was simplified away approximately 1 year ago. There are some tweaks to it : a) exclude promotions; b) exclude Pv Nodes from it - Pv Nodes logic for captures is really different from non Pv nodes so it makes a lot of sense; c) use a big grain of capture history - idea is taken from my recent patches in futility pruning. passed STC https://tests.stockfishchess.org/tests/view/61bd90f857a0d0f327c373b7 LLR: 2.96 (-2.94,2.94) <0.00,2.50> Total: 86640 W: 22474 L: 22110 D: 42056 Elo +1.46 Ptnml(0-2): 268, 9732, 22963, 10082, 275 passed LTC https://tests.stockfishchess.org/tests/view/61be094457a0d0f327c38aa3 LLR: 2.95 (-2.94,2.94) <0.50,3.00> Total: 23240 W: 6079 L: 5838 D: 11323 Elo +3.60 Ptnml(0-2): 14, 2261, 6824, 2512, 9 https://github.com/official-stockfish/Stockfish/pull/3864 bench 4493723 see source |
