## Abstract In this article we study the __group Steiner network__ problem, which is defined in the following way. Given a graph __G__ = (__V,E__), a partition of its vertices into K groups and connectivity requirements between the different groups, the aim is to find simultaneously a set of repres

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
