Title
An Approximation Algorithm For The 2-Dispersion Problem
Abstract
Let P be a set of points on the plane, and d(p, q) be the distance between a pair of points p, q in P. For a point p. P and a subset S subset of P with vertical bar S vertical bar >= 3, the 2-dispersion cost, denoted by cost(2)( p, S), of p with respect to S is the sum of (1) the distance from p to the nearest point in S\{p} and (2) the distance from p to the second nearest point in S\{p}. The 2-dispersion cost cost(2)(S) of S subset of P with vertical bar S vertical bar >= 3 is min(p is an element of S) {cost(2)( p, S)}. Given a set P of n points and an integer k we wish to compute k point subset S of P with maximum cost(2)(S). In this paper we give a simple 1/(4 root 3) approximation algorithm for the problem.
