Title: When is the set covering polyhedron integral?
| Speaker: | Ahmad Abdi |
| Affiliation: | University of Waterloo |
| Room: | MC 5501 |
Abstract: A 0,1 matrix is perfect if its set packing polyhedron is
integral, and it is ideal if its set covering polyhedron is integral. The
Strong Perfect Graph Theorem provides a characterization of perfect
matrices. Is there such a characterization of ideal matrices? So far, there
has not been any...
