Prize-collecting steiner network problems

Abstract

In the Steiner Network problem, we are given a graph G with edge-costs and connectivity requirements r uv between node pairs u,v . The goal is to find a minimum-cost subgraph H of G that contains r uv edge-disjoint paths for all u,v ∈ V . In Prize-Collecting Steiner Network problems, we do not need to satisfy all requirements, but are given a penalty function for violating the connectivity requirements, and the goal is to find a subgraph H that minimizes the cost plus the penalty. The case when r uv ∈ {0,1} is the classic Prize-Collecting Steiner Forest problem.
