ملخص

In minimum power network design problems we are given an undirected graph G= (V, E) with edge costs { c_e: e∈ E}. The goal is to find an edge set F⊆ E that satisfies a prescribed property of minimum power pc(F)=∑v∈Vmax{ce:e∈Fisincidenttov}. In the Min-Power k Edge Disjoint st -Paths problem F should contain k edge disjoint st-paths. The problem admits a k-approximation algorithm, and it was an open question whether it admits an approximation ratio sublinear in k even for unit costs. We give a 42k -approximation algorithm for general costs.
