Approximate ,-MSTs and ,-Steiner Trees via the Primal-Dual Method and Lagrangean Relaxation,ation algorithms. We also derive a constant-factor approximation algorithm for the .-Steiner tree problem using these ideas, and point out the common features of these problems that allow them to be solved with similar techniques.

Circuit Mengerian Directed Graphs,ty is closed under digraph minors, thus Circuit Mengerian digraphs can be characterized by a list of minor minimal non Circuit Mengerian digraphs. In this paper we give such an excluded minor characterization.
