Abstract:
We present a (1 + root 3 + is an element of)-approximation algorithm for the k-median problem with uniform penalties, extending the recent result by Li and Svensson for the classical k-median problem without penalties. One important difference of this work from that of Li and Svensson is a new definition of sparse instance to exploit the combinatorial structure of our problem. (C) 2018 Elsevier B.V.
