RESUMO

A combinatorial optimization problem can be completely caracterized by linear constraints, called facets if they are maximum dimensional faces of the polyhadron defined by the convex hull of the problem. On a polyhedral curts resolution scheme we use this linear description of the problem: we solve by linear classes of the linear description (the ones of a reasonable number of constraints); on the optimal solution we identify facets to be introduced on the problem; surveying the papers on the area, present-ing a description of the TSP facets, and procedures for facet idenfication.
