Dev Builds » 20230723-2356

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 14. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Commit ID 4b2979760f3862700c6a0b8d3ab0f6a6e0a638c0

Check clock more often This patch changes the frequency with which the time is checked, changing frequency from every 1024 counted nodes to every 512 counted nodes. The master value was tuned for the old classical eval, the patch takes the roughly 2x slowdown in nps with SFNNUEv7 into account. This could reduce a bit the losses on time on fishtest, but they are probably unrelated. passed STC: https://tests.stockfishchess.org/tests/view/64bb8ae5dc56e1650abb1b11 LLR: 2.95 (-2.94,2.94) <-1.75,0.25> Total: 76576 W: 19677 L: 19501 D: 37398 Ptnml(0-2): 274, 8592, 20396, 8736, 290 closes https://github.com/official-stockfish/Stockfish/pull/4704 No functional change
