Approximating connected facility location problems via random facility sampling and core detouring
We present a simple randomized algorithmic framework for connected facility location problems. The basic idea is as follows: We run a black-box approximation algorithm for the unc...

Approximation algorithms for connected facility location problems
We study Connected Facility Location problems. We are given a connected graph G = (V, E) with nonnegative edge cost ce for each edge e E, a set of clients D V such that each cli...

Improved Primal-Dual Approximation Algorithm for the Connected Facility Location Problem
In the Connected Facility Location(ConFL) problem, we are given a graph G = (V, E) with nonnegative edge cost ce on the edges, a set of facilities F V , a set of demands, i.e., cl...
