Stefano Moncada,Lino Briguglio,Leonard Nurseertain inequalities, also called conditional. If such a conditional lower bound exceeds some known upper bound, then every solution better than the one corresponding to the upper bound violates at least one of the conditional inequalities. This yields a valid disjunction, which can be used to partit

The algorithm uses a set of heuristics to find prime covers, another set of heuristics to find feasible solutions to the dual linear program which are needed to generate cuts, and subgradient optimization to find lower bounds. It also uses imp

Marc Dumas-Johansen,Andreas Thulstruptrate how the knowledge of the facets of this polytope can be utilized to solve large-scale travelling salesman problems. In particular, we report how the shortest roundtrip through 120 German cities was found using a commercial linear programming code and adding facetial cutting planes in an intera

We implemented a LIFO implicit enumeration algorithm based on this id

Besides a unified formulation of the earlier results some modifications and extensions are presented here underlining the central role which the greedy algorithm plays in combinatorial optimization.
