Dev Builds » 20230822-0914

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.

Simplify Square Clipped ReLU code. Squared numbers are never negative, so barring any wraparound there is no need to clamp to 0. From reading the code, there's no obvious way to get wraparound, so the entire operation can be simplified away. Updated original truncated code comments to be sensible. Verified by running ./stockfish bench 128 1 24 and by the following test: STC: https://tests.stockfishchess.org/tests/view/64da4db95b17f7c21c0eabe7 LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 60224 W: 15425 L: 15236 D: 29563 Ptnml(0-2): 195, 6576, 16382, 6763, 196 closes https://github.com/official-stockfish/Stockfish/pull/4751 No functional change
