A mixed-integer approximation of robust optimization problems with mixed-integer adjustments
Optimization and Engineering, 2023 AbstractIn the present article we propose a mixed-integer approximation of adjustable-robust optimization problems, that have both, continuous and discrete variables on the lowest level. As these trilevel problems are notoriously hard to solve, we restrict ourselves to weakly-connected instances. Our approach allows us to approximate, and in some cases

Automatic instantiation of a Variable Neighborhood Descent from a Mixed Integer Programming model
Operations Research Perspectives, 2017 In this paper we describe the automatic instantiation of a Variable Neighborhood Descent procedure from a Mixed Integer Programming model. We extend a recent approach in which a single neighborhood structure is automatically designed from a Mixed Integer

IDOL: A web application for mixed integer linear multiobjective optimization
SoftwareX, 2022 Practical decision-making very often results in complex multiobjective optimization problems that can be solved only by advanced software. At present, it is available for singleobjective optimization and much less for multiobjective optimization ...
