Dev Builds » 20200418-1336

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

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 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 Ptnml(0-2): 916, 12610, 41383, 13031, 986 closes https://github.com/official-stockfish/Stockfish/pull/2640 bench 4881443
