We give the rst algorithmic result using the bidi-rected cut relaxation for the metric Steiner tree problem: a 3=2+ factor approximation algorithm, for any > 0, for the special case of quasi-bipartite graphs; these are graphs that do not have edges connecting pairs of Steiner vertices. This relaxation is conjectured to have integrality gap close to 1; the worst example known has integrality gap...
