The input to the metric maximum clustering problem with given cluster sizes consists of a complete graph G=(V,E) with edge weights satisfying the triangle inequality, and integers c"1,...,c"p. The goal is to find a partition of V into disjoint clusters of sizes c"1,...,c"p, maximizing the sum of weights of edges whose two ends belong to the same cluster. We describe an approximation algorithms for this problem with performance guarantee that approaches 0.5 when the cluster sizes are large.
