On column generation formulations for the RWA problem

On column generation formulations for the RWA problem We present a review of several column generation formulations for the Routing and Wavelength Assignment ( rwa ) problem with the objective of minimizing the blocking rate. Several improvements are proposed, together with a comparison of the different formulations with respect to the quality of their continuous relaxation bounds and their computing solution ease. Experimental results are presented on several classical network and traffic instances. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Discrete Applied Mathematics Elsevier

Abstract

We present a review of several column generation formulations for the Routing and Wavelength Assignment ( rwa ) problem with the objective of minimizing the blocking rate. Several improvements are proposed, together with a comparison of the different formulations with respect to the quality of their continuous relaxation bounds and their computing solution ease. Experimental results are presented on several classical network and traffic instances.
