We note that with the patch the last use of the venerable "Score" typeĭisappears in Stockfish codebase (the Score type was used in classicalĮvaluation to get a tampered eval interpolating values smoothly from theĮarly midgame stage to the endgame stage). To move, testing the result both on our standard book on positions withĪ strong White bias, and an alternate book with positions with a strong Implementation with a psqt replacement from the point of view of the side The psqt replacement formula was always from the point of view of White,Įven if the side to move was Black. The values obtained via this tuning session were for a model where Tuned weights using spsa at 45+0.45 with: The positional piece square tables (psqt) in the semi-classical complexityĬalculation. This huge simplification uses a weighted material differences instead of Simplify the "Prune moves with negative SEE" formula,īy removing one multiplication and subtraction operation. Tweak formula for pruning moves losing material (this thus is closer to the main search function, which uses the static eval). This patch uses minimum between this tt value and the static eval instead Score is obsolete with the removal of psqt.Ĭurrent master used value from transposition table there if it existed, Makefile script now correctly removes it before trying to download a clean version.
