Paper accepted to 25th International Conference on Principles and Practice of Constraint Programming

Our paper "Exploiting Counterfactuals for Scalable Stochastic Optimization" (with co-authors Dr. Meinolf Sellmann and Stefan Kuhlemann) has been accepted to the 25th International Conference on Principles and Practice of Constraint Programming. The paper provides a machine learning-based mechanism for providing robust solutions to optimization problems with uncertain input parameters.

Paper accepted in European Journal of Operational Research


Our paper "A Branch and Bound Approach for Large Pre-marshalling Problems" has been accepted to the European Journal of Operational Research. The paper was coauthored with Prof. Shunji Tanaka, Consuelo Parreno-Torres, Prof. Ramon Alvarez-Valdes and Prof. Ruben Ruiz. We provide new lower bounds and a specialized branch-and-bound approach for solving the container pre-marshalling problem, an optimization problem found in certain types of container terminals. Our exact approach is extremely fast, providing solutions to even large scale problems in under an hour.
