On the symmetric travelling salesman problem: Solution of a 120-city problem,trate 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 interactive way.

Quadratic knapsack problems,for the QK problem are derived, and their different uses in a branch-and-bound scheme for solving such a problem are discussed. Some theoretical results concerning the class of all upper planes, as well as extensive computational experience, are reported.
