Revolution 3.80 021225 - 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 3.80 021225 what's new?

Summary

  * Moved static evaluation, correction history adjustment, and improving/opponent-worsening calculations ahead of TT cutoffs, including the updated hindsight reduction threshold of 173 to match the latest upstream patch.

  * After tablebase probing, in-check nodes now jump straight to move generation while using the earlier static evaluation placement
