Hybrid Constraint Tightening for Solving Hybrid Scheduling Problems
Hybrid Scheduling Problems (HSPs) contain both temporal and finite-domain variables, as well as constraints between them. A hybrid constraint over temporal and finite-domain varia...

Impairment-Aware Offline RWA for Transparent Optical Networks
—We consider the offline version of the routing and wavelength assignment (RWA) problem in transparent all-optical networks. In such networks and in the absence of regenerators, ...

Network Dimensioning under Scheduled and Random Lightpath Demands in All-Optical WDM Networks
— In WDM optical networks connection requests can be classified into three different types: Permanent Lightpath Demands (PLDs), Scheduled Lightpath Demands (SLDs), and Random Li...
