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

In this paper, we consider the Steiner problem in graphs, which is the problem of connecting together, at minimum cost, a number of vertices in an undirected graph with nonnegative edge costs. We use the formulation of this problem as a shortest spanning tree (SST) problem with additional constraint
