rshogi-core

A high-performance shogi (Japanese chess) engine core library written in Rust.

Features

• Bitboard-based board representation - Fast move generation and position evaluation
• NNUE evaluation - Neural network-based evaluation with HalfKP architecture support
• Alpha-beta search - With various pruning techniques (null move, futility, LMR, etc.)
• Transposition table - Lock-free concurrent hash table
• Time management - Adaptive time control for various time settings
• Multi-threaded search - Lazy SMP parallel search support

Installation

Add this to your Cargo.toml:

[dependencies]
rshogi-core = "0.1"

Usage

use rshogi_core::{Position, SearchOptions, Engine};

// Create a new position (starting position)
let mut pos = Position::default();

// Create engine and search
let mut engine = Engine::new();
engine.set_position(pos);

let options = SearchOptions {
    depth: Some(10),
    ..Default::default()
};

let result = engine.search(&options);
println!("Best move: {}", result.best_move);
