Generalizing Constraint Models in Constraint Acquisition

Dimos Tsouros, Senne Berden, Steven Prestwich, Tias Guns

AAAI 2025technical

Constraint Acquisition (CA) aims to widen the use of constraint programming by assisting users in the modeling process. However, most CA methods suffer from a significant drawback: they learn a single set of individual constraints for a specific problem instance, but cannot generalize these constrai…

Solver-Free Decision-Focused Learning for Linear Optimization Problems

Senne Berden, Ali İrfan Mahmutoğulları, Dimos Tsouros, Tias Guns

NeurIPS 2025poster

Mathematical optimization is a fundamental tool for decision-making in a wide range of applications. However, in many real-world scenarios, the parameters of the optimization problem are not known a priori and must be predicted from contextual features. This gives rise to predict-then-optimize probl…
