A matheuristic for tri-objective binary integer programming
Duleabom An, Sophie N. Parragh, Markus Sinnl +1
Many real-world optimisation problems involve multiple objectives. When considered concurrently, they give rise to a set of optimal trade-off solutions, also known as efficient sol…
A lexicographic maximin approach to the selective assessment routing problem
Mohammadmehdi Hakimifar, Vera Hemmelmayr, Fabien Tricoire
Max-min approaches have been widely applied to address equity as an essential consideration in humanitarian operations. These approaches, however, have a significant drawback of be…
An outer approximation algorithm for multi-objective mixed-integer linear and non-linear programming
Fritz Bökler, Sophie N. Parragh, Markus Sinnl +1
In this paper, we present the first outer approximation algorithm for multi-objective mixed-integer linear programming problems with any number of objectives. The algorithm also wo…
A LP relaxation based matheuristic for multi-objective integer programming
Duleabom An, Sophie N. Parragh, Markus Sinnl +1
Motivated by their success in the single-objective domain, we propose a very simple linear programming-based matheuristic for tri-objective binary integer programming. To tackle th…
A branch-and-Benders-cut algorithm for a bi-objective stochastic facility location problem
Sophie N. Parragh, Fabien Tricoire, Walter Gutjahr
In many real-world optimization problems, more than one objective plays a role and input parameters are subject to uncertainty. In this paper, motivated by applications in disaster…
