摘要:

We present a (1 + √3 + Ε)-approximation algorithm for the k-median problem with uniform penalties in polynomial time, 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. © Springer International Publishing AG 2016.
