Dev Builds » 20200210-0819

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.

Modify singular beta for ttPv positions. This patch lowers singular beta for positions that have been in pv and are not pv nodes. The idea of using ttpv && !PvNode improved scaling with TC and could be useful for other search heuristics. passed STC http://tests.stockfishchess.org/tests/view/5e3f6d7ce70d848499f63bbc LLR: 2.94 (-2.94,2.94) {-0.50,1.50} Total: 154953 W: 29688 L: 29272 D: 95993 Ptnml(0-2): 2616, 17912, 36037, 18210, 2673 passed LTC http://tests.stockfishchess.org/tests/view/5e405561e70d848499f63bfa LLR: 2.95 (-2.94,2.94) {0.25,1.75} Total: 70974 W: 9305 L: 8932 D: 52737 Ptnml(0-2): 466, 6658, 20920, 6826, 569 closes https://github.com/official-stockfish/Stockfish/pull/2550 Bench: 4932981
