Overcoming Over-Fitting in Constraint Acquisition via Query-Driven Interactive Refinement
Vasileios Balafas, Dimos Tsouros, Nikolaos Ploskas +1
Manual modeling in Constraint Programming is a substantial bottleneck, which Constraint Acquisition (CA) aims to automate. However, passive CA methods are prone to over-fitting, of…
Integer programming models for the semi-obnoxious p-median problem
Nikolaos Ploskas, Kostas Stergiou
The p-median problem concerns the location of facilities so that the sum of distances between the demand points and their nearest facility is minimized. We study a variant of this…
Optimization of circuitry arrangements for heat exchangers using derivative-free optimization
Nikolaos Ploskas, Christopher Laughman, Arvind U. Raghunathan +1
Optimization of the refrigerant circuitry can improve a heat exchanger's performance. Design engineers currently choose the refrigerant circuitry according to their experience and…
