WebMar 1, 2024 · If is a cover, then the inequality is valid for the knapsack polytope [8]. It is called a cover inequality (CI). A cover (and the associated CI) is minimal if for all . Minimal CIs dominate all other CIs. Unfortunately, minimal CIs do not in general define facets of the knapsack polytope. WebA cutting plane is a valid inequality that cuts off a portion of the linear relaxation space. This thesis presents a new class of cutting planes referred to as merged knapsack cover inequalities (MKCI). These valid inequalities combine information from a cover inequality with a knapsack constraint to generate stronger inequalities.
