Given a set S of starting vertices and a set T of terminating vertices in a graph G = (V,E) with non-negative weights on edges, the minimum Steiner network problem is to find a subgraph of G with the minimum total edge weight. In such a subgraph, we require that for each vertex s $${\in}$$ S and t $${\in}$$ T, there is a path from s to a terminating vertex as well as a path from a starting vertex...
