Revolution 3.0 011125 - UCI chess engine (based on Stockfish)

Revolution - Revolution is a free, open-source UCI chess engine derived from Stockfish. Jorge Ruiz Centelles, with credit to ChatGPT, modifies and extends the code to explore new concepts. The engine implements cutting-edge search algorithms combined with neural network evaluation. Derived from fundamental chess programming principles, Revolution analyzes positions through parallelized alpha-beta search enhanced with null-move pruning and late move reductions.

As a UCI-compliant engine, Revolution operates through standard chess interfaces without an integrated graphical interface. Users must employ compatible chess GUIs (Arena, Scid vs PC, etc.) for board visualization and move input. Consult your GUI documentation for implementation details.

Revolution 3.0 011125 what's new?

Removed the statScore contribution from the futility pruning margin to align with the latest Stockfish simplification.

Dynamic adjustment of reductions in PVS.

Vectorization of feature evaluations.

Persistent killer move cache.

Rounded the half-draw contribution when converting precomputed WDL scores to win probabilities so the reported values no longer suffer from systematic downward bias.
