Shogi Engine

This is the Shogi game engine, implementing the USI (Universal Shogi Interface) protocol.

Building

# Standard build (SIMD optimizations enabled by default)
cargo build --release --bin usi-engine

# Build without SIMD optimizations (if needed for compatibility)
cargo build --release --bin usi-engine --no-default-features --features hierarchical-tt

Running

The engine runs as a USI-compatible process, communicating via stdin/stdout.

Features

• SIMD Optimizations: Enabled by default for optimal performance (x86_64 with AVX2/SSE, ARM64 with NEON). Provides 2-4x speedup for bitwise operations and 20%+ overall NPS improvement. Note: WebAssembly support has been removed - SIMD is native-only. Disable with --no-default-features if needed.
