A chess engine.

Features:

  • Negamax search
  • Alpha-beta pruning

  • UCI compatibility
  • Iterative deepening
  • Transposition table (Zobrist hashing)
    • Currently only stores best move.

instructions

To run the engine (in UCI mode):

cargo run --release

Quick unit tests:

cargo test

Longer duration, more rigorous tests:

cargo test --release

Flamegraph (on perft):

export CARGO_PROFILE_RELEASE_DEBUG true
cargo flamegraph --test perft
