Differential evolution(DE)algorithm has attracted more and more attention due to its fast optimization performance and good stability.When DE algorithm is applied into multi-constrained multicast routing optimization problem,a common solution to such problem is to merge the paths into a tree after finding paths from the source node to each destination node.This method maybe obtains the better result,but it can consume a lot of computational time.To solve the problem,a tree-based DE algorithm is introduced in this paper.The central operations of the algorithm are realized with tree structure.This method saves the time of finding paths and integrating them to construct a multicast tree.The experiments show that the proposed algorithm can achieve higher success rate than several common algorithms with much smaller running time for different networks.
