Windows x64 for Haswell CPUs Windows x64 for modern computers Windows x64 Windows 32 Linux x64 for Haswell CPUs Linux x64 for modern computers Linux x64 | Author: Vizvezdenec Date: Sat Apr 18 15:36:41 2020 +0200 Timestamp: 1587217001 Apply multicut pruning more often This patch increases number of nodes where we produce multicut cutoffs. The idea is that if our ttMove failed to produce a singular extension but ttValue is greater than beta we can afford to do one more reduced search near beta excluding ttMove to see if it will produce a fail high - and if it does so produce muticut by analogy to existing logic. passed STC https://tests.stockfishchess.org/tests/view/5e9a162b5b664cdba0ce6e28 LLR: 2.94 (-2.94,2.94) {-0.50,1.50} Total: 58238 W: 11192 L: 10917 D: 36129 Elo +1.64 Ptnml(0-2): 1007, 6704, 13442, 6939, 1027 passed LTC https://tests.stockfishchess.org/tests/view/5e9a1e845b664cdba0ce7411 LLR: 2.94 (-2.94,2.94) {0.25,1.75} Total: 137852 W: 17460 L: 16899 D: 103493 Elo +1.41 Ptnml(0-2): 916, 12610, 41383, 13031, 986 closes https://github.com/official-stockfish/Stockfish/pull/2640 bench 4881443 | Windows x64 for Haswell CPUs Windows x64 for modern computers Windows x64 Windows 32 Linux x64 for Haswell CPUs Linux x64 for modern computers Linux x64 | Author: protonspring Date: Sat Apr 18 15:29:24 2020 +0200 Timestamp: 1587216564 Simplify minPawnDistance This is a functional simplification which fixes an awkward numerical cliff. With master king_safety, no pawns is scored higher than pawn(s) that is/are far from the king. This may motivate SF to throw away pawns to increase king safety. With this patch, there is a consistent value for minPawnDistance where losing a pawn never increases king safety.
