  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 240324 download

A kimbo   is a UCI compatible Chess (and Chess960) engine written in Rust. Rating CEDR =3504 v.1.0.0: This (probably) marks the final release where akimbo's NNUE is wholly original, I have spent (wasted?) hundreds of hours of compute generating training data on 6 threads, and really cannot be bothered to do any more of it, so future releases will likely use external data. I have thus incremented the major version number to indicate this, as well as the fact that akimbo now contains all of the biggest functional features (SMP, DFRC, etc). Main Features NNUE Speedups A few small search improvements Replaced oldest data with new data New network, trained on 1.5bn positions with arch (768x4hm -> 1024)x2 -> 1 Full Changelog: v0.8.0...v1.0.0 Self-Play against v0.8.0 Couldn't be bothered to run a full progtest, it should hopefully scale better due to the larger network.

LcZero - CEDR Rating=3708 v0.31.0-rc1: In this version: The blas, cuda, eigen, metal and onnx backends now have support for multihead network architecture and can run BT3/BT4 nets. Updated the internal Elo model to better align with regular Elo for human players. There is a new XLA backend that uses OpenXLA compiler to produce code to execute the neural network. See https://github.com/LeelaChessZero/lc0/wiki/XLA-backend for details. Related are new leela2onnx options to output the HLO format that XLA understands. There is a vastly simplified lc0 interface available by renaming the executable to lc0simple. The backends can now suggest a minibatch size to the search, this is enabled by --minibatch-size=0 (the new default). If the cudnn backend detected an unsupported network architecture it will switch to the cuda backend. Two new selfplay options enable value and policy tournaments. A policy tournament is using a single node policy to select the move to play, while a value tournament ...
