Multiobjective optimization in optical networks for multicast transmission using evolutionary algorithms and fuzzy logic

Abstract

Abstract
In this paper, we develop a fuzzy analytical model, which solves a multiobjective problem in multicast transmission with static trees over GMPLS networks. A model proponed by Donoso [4] was used. The multiobjective problem is solved through metaheuristic wit h evolutionary algorithms, in this case SPEA2 solving a NP-Hard problem in polynomial time. Additionally, a Fuzzy Evolutionary Algorithm based on SPEA2 is implemented.
Finally, the comparison between FSPEA2 and SPEA2 is realized and we are
giving some conclusions.
