  ShashChess -  is a free UCI chess engine derived from Stockfish family chess engines.  Rating CEDR=3398 Android builds were generated with CECSA (Chess Engine Compiler Script for Android). Chess engines are located in the libs directory and are available for arm64-v8a, armeabi-v7a, x86 and x86_64 based devices. If a chess engine supports NNUE (Neural Network Updated Efficiently) technology and the network is not embedded in the binary, you will find the missing network file in the networks directory.

Author: Connor McMonigle  Rating CEDR=3049 v.2.7.0 This release adds an estimated 50 Elo in self play under UHO testing conditions. This improvement in strength can be attributed to further optimizations to the network inference implementation, an improved network trained using a new regularization scheme, and a number of miscellaneous search improvements in roughly equal measure. As was the case for the prior release, the embedded network was trained solely on data originating from Seer produced by way of many self play iterations starting with the initial "retrograde learning" network bundled with v2.0.0-v2.1.0 as a base. Android builds were generated with Android NDK Seer 2.7.0 for Android download Seer 2.7.0 NNUE for Windows

CederChess - a chess engine by Claus Cederberg CederChess is a chess engine written in the C++ programming language. It is an ungoing project, and hopefully the future versions will become better and better. Currently I'm working on version 2. It all started many years ago when I was a student. Me and a co-student wrote a chess engine called ChickenChess in the start 1990s. All programs we wrote at that time was called something starting with "Chicken". I can't remember why. The engine wasn't particulary good, but we passed the examination. Then around 2014 or so, I read a paper describing an engine where the evaluation score only depended on material and positions, nothing else. I can't find the paper now. I implemented it in Java and forgot all about it. Then in 2022, I was again interested in chess and chess engines and decided to rewrite the Java program to a C program and get it on CCRL Blitz. The rewriting took some effort, because I also wanted it to b...
