Dev Builds » 20211201-1722

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.

Correctly reset bestMoveChanges for searches not using time management (e.g. analysis, fixed node game play etc), bestMoveChanges was not reset during search iterations. As LMR uses this quantity, search was somewhat weaker. Tested using fixed node playing games: ``` ./c-chess-cli -each nodes=10000 option.Hash=16 -engine cmd=../Stockfish/src/fix -engine cmd=../Stockfish/src/master -concurrency 6 -openings file=../books/UHO_XXL_+0.90_+1.19.epd -games 10000 Score of Stockfish Fix vs Stockfish Master: 3187 - 3028 - 3785 [0.508] 10000 ./c-chess-cli -each nodes=30000 option.Hash=16 -engine cmd=../Stockfish/src/fix -engine cmd=../Stockfish/src/master -concurrency 6 -openings file=../books/UHO_XXL_+0.90_+1.19.epd -games 10000 Score of Stockfish Fix vs Stockfish Master: 2946 - 2834 - 4220 [0.506] 10000 ``` closes https://github.com/official-stockfish/Stockfish/pull/3818 bench: 5061979
