Popis: Given a set P of n points on which facilities can be placed and an integer k, we want to place k facilities on some points so that the minimum distance between facilities is maximized. The problem is called the k-dispersion problem. In this paper we consider the 3-dispersion problem when P is a set of points on a plane. Note that the 2-dispersion problem corresponds to the diameter problem. We give an O(n) time algorithm to solve the 3-dispersion problem in the \(L_{\infty }\) metric, and an O(n) time algorithm to solve the 3-dispersion problem in the \(L_1\) metric. Also we give an \(O(n^2\log n)\) time algorithm to solve the 3-dispersion problem in the \(L_2\) metric.
