bisec-tree's Introduction

bisec-tree

Bisector tree implementation in OCaml.

A bisector tree allows to do fast and exact nearest neighbor searches in any space provided that you have a metric (function) to measure the distance between any two points in that space.

Cf. this article for details: "A Data Structure and an Algorithm for the Nearest Point Problem"; Iraj Kalaranti and Gerard McDonald. ieeexplore.ieee.org/iel5/32/35936/01703102.pdf
