In this study, the Brunn-Minkowski inequality for boxes is studied and a sharper version of derived by performing results based on abstract convexity.

This paper considers the Economic Lot Scheduling Problem, that is, the problem of scheduling several products on a single facility so as to minimize holding and setup costs. Combination of frequency and timing as well as production quantity make this problem Np-hard. A heuristic is developed to obtain a good solution to ELSP. The proposed heuristic makes use of the Simulated Annealing Technique...

In this paper we improve on some results of 3] and extend them to the setting of implicit deenability. We show a strong necessary condition on classes of structures on which PSPACE can be captured by extending PFP with a nite set of generalized quantiiers. For IFP and PTIME the limitation of expressive power of generalized quantiiers is shown only on some speciic nontrivial classes. These resul...
