摘要
The natural linear programming formulation of the maximum s-t-flow problem in path variables has a dual linear program whose underlying polyhedron is the dominant P(s-t-cut)(up arrow) of the s-t-cut polytope. We present a complete characterization of P(s-t-cut)(up arrow) with respect to vertices, facets, and adjacency.
