Abstract

This entry provides a formalization of multidimensional binary trees, also known as k-d trees. It includes a balanced build algorithm as well as the nearest neighbor algorithm and the range search algorithm. It is based on the papers Multidimensional binary search trees used for associative searching and An Algorithm for Finding Best Matches in Logarithmic Expected Time.
