Chess engine: Stockfish 19091210

-
Stockfish - UCI chess engine
Interesting compiled by Vizvezdenec

 This patch greatly scales down complexity of endgames when the 
following conditions are all true together: 

 - pawns are all on one flank 
- stronger side king is not outflanking weaker side 
- no passed pawns are present 

 This should improve stockfish evaluation of obvious draws 4 vs 3, 3 vs 2 and 2 vs 1 pawns in rook/queen/knight/bishop single flank endgames where strong side can not make progress. 

 passed STC 
LLR: 2.94 (-2.94,2.94) [0.50,4.50] 
Total: 15843 W: 3601 L: 3359 D: 8883 Elo +5.31

 passed LTC 
LLR: 2.96 (-2.94,2.94) [0.00,3.50] 
Total: 121275 W: 20107 L: 19597 D: 81571 Elo +1.46

New chess engine: HypnoS 190324 (derived from Stockfish)

-
Image
  HypnoS is a free and strong UCI chess engine derived from Stockfish  that analyzes chess positions and computes the optimal moves. HypnoS does not include a graphical user interface (GUI) that is required  to display a chessboard and to make it easy to input moves. These GUIs are  developed independently from HypnoS and are available online. HypnoS development is currently supported on the Openbench framework. OpenBench (created by Andrew Grant) is an open-source Sequential Probability Ratio Testing (SPRT) framework designed for self-play testing of engines. OpenBench makes use of distributed computing, allowing anyone to contribute CPU time to further the development of some of the world's most powerful engines. HypnoS 190324 download

Chess engine: SF 16.1 MPV

-

Author, Eduard Nemeth: This engine is better suited for analysis than the current newer developer versions. The following version is maybe even better. I implemented the network with Dimension 3072 as well as the Random Op. MultiPV mode. Other features include Minimum Thinking Time and Slow Mover. As default is Random Op. MultiPV = 3. I consider this setting to be the best for tactical analysis. With Random Op. MultiPV = 1 the engine behaves like Stockfish 16.1 with network dimension 3072. The original SF 16.1 uses a NNUE with dimension 2560. Download SF 16.1 MPV
