摘要

引入并改进NSGA-II算法，用于解决GMPLS光网络的流量工程问题.首先给出流量工程问题数学模型；然后提出一个基于线性规划和NSGA-II的混合启发性算法；最后对算法进行仿真，将结果与车比雪夫精确算法所得结果进行比较，验证了本算法的有效性.

Abstract

In this paper

we introduce and devise Non-dominated Sorting Genetic Algorithm (NSGA-II) for solving the constrained multipath traffic engineering problem in GMPLS optical networks.A formulation of this problem as a multiobjective constrained optimization is first extended.Then

we develop a hybrid heuristic algorithm based on linear programming.We also compare the performance of the proposed heuristic using a similar problem adopted from the literature with the exact solutions generated using a lexicographic Chebyshev method.
