On the Additive Constant of the k-server Work Function Algorithm

Data Structures and Algorithms 2009-02-10 v1

Abstract

We consider the Work Function Algorithm for the k-server problem. We show that if the Work Function Algorithm is c-competitive, then it is also strictly (2c)-competitive. As a consequence of [Koutsoupias and Papadimitriou, JACM 1995] this also shows that the Work Function Algorithm is strictly (4k-2)-competitive.
