WebWe present a rich, bi-objective generalization of the orienteering problem.A modular bi-objective large neighborhood search metaheuristic is proposed.We conduct an extensive computational study on real-life-inspired test instances.Near-optimal Pareto sets are rapidly found on instances solvable to optimality.Solution quality, computation time, and … WebJan 14, 2011 · In many mixed integer programs there is some embedded problem structure which can be exploited, often by a decomposition. When the relaxation in each node of a branch-andbound tree is solved by column generation, one speaks of branch-and-price. Optionally, cutting planes can be added in order to strengthen the relaxation, and this is …
