Transforming clique tree inequalities to induce facets for the 2-edge connected polytope

Conference ·
OSTI ID:35858

The 2-edge connected polytope Q{sub 2E}{sup n} is the convex hull of all 0-1 incidence vectors of 2-edge connected spanning subgraphs of the complete graph K{sub n}. This polytope is related to the travelling salesman polytope, which is a face of Q{sub 2E}{sup n}. By exploiting this relationship and applying the theory from Boyd and Pulleyblank (1991), we show how the clique tree inequalities for the traveling salesman polytope can be transformed into a large new class of facet-inducing inequalities for Q{sub 2E}{sup n}. We also discuss how this class can be generalized to include the lifted 2-cover inequalities introduced by Grotschel, Monma and Stoer (1989).
