In this paper, we introduce a new class of valid inequalities for the polytope associated with the minimum cost 2-edge-connected subgraph problem, and give necessary and sufficient conditions for these inequalities to be facet inducing for this polytope. We believe it will be possible to use these inequalities efficiently in a cutting plane procedure for designing minimum cost survivable communication networks. 2009-03-23T16:03:56Z 2009-03-23T16:03:56Z 1991 1991 Thesis Source: Masters Abstracts International, Volume: 31-01, page: 0345. 9780315680937 http://hdl.handle.net/10393/7818 http://dx.doi.org/10.20381/ruor-15519 62 p.

In this paper, we introduce a new class of valid inequalities for the polytope associated with the minimum cost 2-edge-connected subgraph problem, and give necessary and sufficient conditions for these inequalities to be facet inducing for this polytope. We believe it will be possible to use these inequalities efficiently in a cutting plane procedure for designing minimum cost survivable communication networks. |
