A high-performance C++ library for approximate nearest neighbor search with SIMD optimizations and multiple backend implementations

Strengths

Excellent code organization with clear separation of concerns, comprehensive SIMD optimizations, robust build system, and well-documented architecture. Strong focus on performance with memory-efficient designs and flexible backend support.

Weaknesses

Some Python bindings appear incomplete compared to C++ implementation. Error handling could be more explicit for edge cases like empty indices or dimension mismatches in certain modules.
