Supercluster.KDTree

This is an extremely-fast and easy to use KDTree written entirely in modern C#. This is the fastest and simplest to use KDTree that I have been able to find for .NET. The project has thorough documentation and is open-source. This module is a part of the larger Supercluster project.

HNSWIndex

HNSWIndex provides a high-performance, approximate nearest-neighbor search solution using the HNSW data structure. It supports custom distance metrics, efficient searching with concurrency, and configurable parameters to balance speed, recall, and memory usage. Perfect for .NET applications that require fast similarity lookups (e.g., image retrieval, recommendation systems, or vector-based search).
