1 # Stellar 2 3 UCI bitboard chess engine written in C++20 4 5 6 ## Description 7 8 The goal of the project is experimentation. I want to see how far I can push 9 the engine to play better while learning various techniques of optimization. 10 11 To see the games played or play a game on your own checkout the profile on 12 [lichess](https://lichess.org/@/StellarBOT), bullet, blitz and rapid challenges, ranked or casual, are accepted. 13 14 Check out the games carried out by [CCLR](http://computerchess.org.uk/ccrl/404/) 15 for up to date rating against other engines. 16 17 18 ## Getting Started 19 20 ### Dependencies 21 22 - Linux 23 * CMake 3.25.2 or latter 24 * Compiler with C++20 support (tested: clang 16.0.5, gcc 13.2.0) 25 26 - Windows 27 * Visual Studio (tested: Community 2022 17.9.2) 28 29 30 ### Installing 31 32 * Clone the repo 33 * Make a build folder and cd into it 34 * Run `cmake -DCMAKE_BUILD_TYPE=Release <path to cloned repo>` 35 36 37 ### Executing program 38 39 * Run the engine by running: `./bin/engine` 40 41 * The engine accepts commands on the standard input and produces results to the standard output 42 * To communicate with the engine use UCI command. Reference for UCI protocol can be found [here](http://download.shredderchess.com/div/uci.zip) 43 44 45 ## Help 46 47 * To see the options for additional tools run one of the following commands form the build directory: 48 ``` 49 ./bin/perft -h 50 ``` 51 * Changes to the move generation can be tested with `ctest` on a predefined set of positions 52 53 54 ## Version History 55 56 - 1.4 57 * Better time management 58 * Pawn hash table 59 60 - 1.3 61 * Build engine on Windows using Visual Studio 62 * Improve compilation time 63 64 - 1.2 65 * Improved evaluation using interpolation 66 * Incremental sorting 67 * Fix timeouts 68 69 - 1.1 70 * Add Arena 71 72 - 1.0 73 * Initial Release 74 75 ## License 76 77 This project is licensed under the MIT License - see the LICENSE.md file for details 78 79 80 ## Acknowledgments 81 82 Big thanks to [Gabor Szots](https://github.com/SzotsGabor) from CCRL testing 83 group, for taking an interest in this project by allowing Stellar to compete 84 with other engines. 85 86 Inspiration, code snippets, etc. 87 * [Chess Programming Wiki](https://www.chessprogramming.org/) 88 * [Code Monkey King](https://github.com/maksimKorzh) 89 * [Lichess-Bot](https://github.com/lichess-bot-devs/lichess-bot) 90
