We combine mixed integer linear programming (MILP) and constraint programming (CP) to minimize tardiness in planning and scheduling. Tasks are allocated to facilities using MILP an...
The concept of dominance among nodes of a branch-decision tree, although known since a long time, is not exploited by general-purpose Mixed-Integer Linear Programming (MILP) enume...
Abstract— We explore network design principles for nextgeneration all-optical wide-area networks, employing light-trail technology. Light-trail [1] is a light-wave circuit that a...

Recently, there has been much interest in enhancing purely combinatorial formalisms with numerical information. For example, planning formalisms can be enriched by taking resource...
Passengers travelling in public transportation networks often have to use different lines to cover the trip from their origin to the desired destination. As a consequence, the rel...
