Packing Steiner trees: Further facets

Abstract

In this paper we continue the investigations in [3] for the Steiner tree packing polyhedron. We present several new classes of valid inequalities and give sufficient (and necessary) conditions for these inequalities to be facet-definining. It is intended to incorporate these inequalities into an existing cutting plane algorithm that is applicable to practical problems arising in the design of electronic curcuits. © 1995 Academic Press Limited.
