Optimal solutions for a class of point retrieval problems

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

Let P be a set of n points in the Euclidean plane and let C be a convex figure. We study the problem of preprocessing P so that for any query point q, the points of P in C + q can be retrieved efficiently. If constant time suffices for deciding the inclusion of a point in C, we then demonstrate the existence of an optimal solution: the algorithm requires O(n) space and O(k + log n) time for a query with output size k. If C is a disk, the problem becomes the well-known fized radius neighbor problem, to which we thus provide the first known optimal solution.
