Dev Builds » 20170508-0411

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.

Notice: NCM upgraded all servers to to Ubuntu 18.04 (from 16.04) on October 23rd. Binaries compiled on the upgraded disto are skewing measurements upwards. We are working on a fix.
