Abstract or Table of Contents
We give a simple algorithm for the Minimum Directed Multicut problem, and show that it gives an O(√n)-approximation. This improves on the previous approximation guarantee of O(√n log k) of Cheriyan, Karloff and Rabani , which was obtained by a more sophisticated algorithm.
