摘要：
In the present paper in terms of the graph theory we describe the structure and vertices adjacency criterion of b-factors polyhedron. The special attention is paid to nonintegral vertices. Results of the present paper, in particular, generalize properties of nonintegral vertices of TSP polyhedron, give vertices adjacency criterion of a transportation polytope. © 2014 Allerton Press, Inc.
