Source code structure

main.cpp contains the entire base implementation of the engine.

I know what you're thinking - one big file, really? Yes. I've found it to be simpler this way;

• Faster compilation times.
• No annoying header files with decentralized code.

Implementation Considerations

The engine is implemented with UCI integration in mind, so a global state (enclosed in the state namespace) is used to maintain information about the position.

Performance-Enhancing Features

• Bitboards.
• Bitwise Move Encoding.
• Magic Bitboards, an amazing way to generate slider moves fast.
• Rudimentary Piece-Square Tables.
• MVV-LVA.
• Quiescence Search.
• Negamax as an implementation of Minimax.
• Alpha-Beta Pruning.
• History Heuristic.
• Killer Heuristic.
• Principal Variation Table.

Web Demo

web_build.cpp is used for the demo. make webassembly compiles the file to WebAssembly and exposes an API that the frontend script can interact with.
