A 6.55 factor 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 c e on the edges, a set of facilities ℱ⊆ V, a set of demands (i.e., clients)$\mathcal{D}\subseteq V$, and a parameter M≥1. Each facility i has a nonnegative opening cost f i and each client...
