An approximation algorithm for the k-generalized Steiner forest problem

In this paper, we introduce the k-generalized Steiner forest (k-GSF) problem, which is a natural generalization of the k-Steiner forest problem and the generalized Steiner forest problem. In this problem, we are given a connected graph null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null null...
