Marvin 3.5.0

Post by Martin » Thu Feb 13, 2020 5:44 pm

Marvin 3.5.0 is now available. It's about 30 elo stronger than 3.4.0, and maybe 20 elo stronger than the version that played in TCEC S17. Most of the work for this release have been focused on the evaluation so that's where most of the improvements comes from. For the next release I plan to focus more on the search.

Release notes:
  • Increased max hash size to 128GB
  • Increased max number of threads to 512
  • Added threat evaluation (inspired by Stockfish, Ethereal and Arasan)
  • Added evaluation of connected pawns
  • Added space evaluation
  • Improvements to time management

Binaries: ... tag/v3.5.0
