Dev Builds » 20140101-1158

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.

Simplify move_importance() Drop a useless parameter. This works because ratio1 and ratio2 are ratios of linear combinations of thisMoveImportance and otherMovesImportance and so the yscale cancels out. Therefore the values of ratio1 and ratio2 are independent of yscale and yscale can be retired. The same applies to yshift, but here we want to ensure move_importance() > 0, so directly hard-code this safety guard in function definition. Actually there are some small differences due to rounding errors and usually are at most few millisecond, that's means below 1% of returned time, apart from very short intervals in which a difference of just 1 msec can raise to 2-3% of total available time. No functional change.
