The chess engine discussed in this book is Rustic, which is written in the Rust programming language. The engine is an original work, but it implements many well-known concepts, both from computer science in general, and chess programming in particular.
Rustic is an open-source engine licensed under GPL v3, so anyone can download the source code and change it to their liking, and compile it for their particular platform or CPU. Creating derivative works is possible, within the rules stated by GPL v3.
At the time of writing, March 23rd of 2021, the engine's version is Rustic Alpha 2, with the following features:
- Board representation
- Fancy magic bitboards
- Move generator
- Make/Unmake move
- Alpha-Beta search
- Transposition Table
- MVV-LVA move sorting
- Transposition table move sorting
- Material count + PST evaluation
- Simple time management
- UCI protocol support
Obviously the feature list will grow longer as the engine gets developed further. The book will chronicle those developments and descibe how each feature is implemented. Example code will be in Rust, coming straight from a working version of the engine, but there will be enough explanation so that each feature can be rewritten in any desired programming language.
The programming language obviously needs the right capabilities, so please note that something like WhiteSpace is probably out; and even if the language can do it, it's your own responsibility. Any and all suffering will be of your own making. Choose your language wisely.
