The cover tree is a type of data structure in computer science that is specifically designed to facilitate the speed-up of a nearest neighbor search. It is a refinement of the Navigating Net data structure, and related to a variety of other data structures developed for indexing intrinsically low-dimensional data. * Nesting: * Covering: For every point , there exists a point such that the distance from to is less than or equal to and exactly one such is a parent of . * Separation: For all points , the distance from to is greater than .
