fast approximate nearest neighbor search
Header-only C++ HNSW implementation with Python bindings.
A common task in data analysis but also in scientific computations is to find data that is very close (multi-dimensional space) or similar (same thing) to a given data point. Also as heuristics for physics engines, it is the objects closest to you that you are most likely to collide with. This library knows how to do this fast.
