N2 - We give an implementation of the Goemans-Williamson clustering procedure which is at the core of several approximation algorithms including those for Generalized Steiner Trees, Prize Collecting Travelling Salesman, 2-Edge Connected Subgraph etc. On a graph with n nodes and m edge, our implementation gives &Ogr; (k(n + m) log 2 n) time approximation algorithms for all these problems at the expense of a slight additive degradation of 1/n k in the approximation factor, for any constant k.
