本文首先提出带宽延时约束、费用最小QoS组播路由模型
然后提出解决QoS组播路由问题的一种启发式遗传算法
该算法有以下特点:(1)预处理机制;(2)树结构编码;(3)启发式交叉策略;(4)指导性变异过程.最后通过仿真实验证明该算法快速有效.
We first introduce the bandwidth-delay-constrained least-cost multicast routing problem
and then propose a related heuristic genetic algorithm.The algorithm has the following characteristics:(1)the preprocessing mechanism
(2)the tree structure coding method
(3)the heuristic crossover technique
and (4)the instructional mutation process.Finally
simulations are showed to prove that the genetic algorithm is efficient and effective.
