Intersection Cuts and Corner Polyhedra,ion cuts. It turns out that they are equivalent: the nontrivial valid inequalities for the corner polyhedron are exactly the intersection cuts. Within this framework, we stress two ideas: the best possible intersection cuts are generated from maximal lattice-free convex sets, and formulas for these

Valid Inequalities for Structured Integer Programs,g plane scheme. All these valid inequalities are “general purpose,” in the sense that their derivation does not take into consideration the structure of the specific problem at hand. Many integer programs have an underlying combinatorial structure, which can be exploited to derive “strong” valid ine

Reformulations and Relaxations,example, when the constraints can be partitioned into a set of nice constraints and the remaining set of complicating constraints, a Lagrangian approach may be appropriate. The Lagrangian dual provides a bound that can be stronger than that obtained by solving the usual linear programming relaxation
