The group Steiner tree problem is a generalization of the Steiner tree problem where we are given several subsets (groups) of vertices in a weighted graph, and the goal is to find a minimum-weight connected subgraph containing at least one vertex from each group.The problem was introduced by Reich a
Given an undirected graph G = (V; E), an edge cost c(e) ΒΏ 0 for each edge e β E, a vertex prize p(v) ΒΏ 0 for each vertex v β V , and an edge budget B. The BUDGET PRIZE COLLECTING TREE PROBLEM is to ΓΏnd a subtree T = (V ; E ) that maximizes vβV p(v), subject to eβE c(e) 6 B. We present a (4 + )-appro
