Dev Builds » 20210805-1441

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.

Revert futility pruning patches reverts 09b6d28391cf582d99897360b225bcbbe38dd1c6 and dbd7f602d3c7622df294f87d7239b5aaf31f695f that significantly impact mate finding capabilities. For example on ChestUCI_23102018.epd, at 1M nodes, the number of mates found is nearly reduced 2x without these depth conditions: sf6 2091 sf7 2093 sf8 2107 sf9 2062 sf10 2208 sf11 2552 sf12 2563 sf13 2509 sf14 2427 master 1246 patched 2467 (script for testing at https://github.com/official-stockfish/Stockfish/files/6936412/matecheck.zip) closes https://github.com/official-stockfish/Stockfish/pull/3641 fixes https://github.com/official-stockfish/Stockfish/issues/3627 Bench: 5467570
