Abstract

The k -partition problem seeks to cluster the vertices of an edge-weighted graph, G = ( V , E ), into k sets of | V |/ k vertices each, such that the total weight of the edges having both endpoints in the same cluster is maximized. Bottom-up type heuristics based on matchings are presented for this problem. These heuristics are shown to yield solutions that are at least one-half the weight of the optimal solution for k equal to | V |/3 and | V |/4.
