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 study the Node Weighted Steiner Tree Problem (NSP). This problem is a generalization of the Steiner tree problem in the sense that vertex weights are considered. Given an undirected graph, the problem is to find a tree that spans a subset of the vertices and is such that the total
In this paper we present an RNC approximation algorithm for the Steiner tree problem in graphs with performance ratio 5r3 and RNC approximation algorithms for the Steiner tree problem in networks with performance ratio 5r3 q β for all β ) 0. This is achieved by considering a related problem, the min
