摘要: QoS multicast routing problem in WDM networks is investigated, and an improved algorithm Multi-granularity Evolution based Quantum Genetic Algorithm (MEQGA) proposed to address it. Based on (QGA) with quantum rotation gate strategy, MEQGA introduces multi-granularity evolution mechanism, which allows different chromosomes of one generation have angle step values update. In term this can significantly improve its capability exploration exploitation, since optimization performance does not over-depend the single scheme shared by all any longer. also presents adaptive mutation operation able avoid local search efficiently. A repair method applied eliminate illegal graphs as many possible hence more excellent solutions will appear each evolutionary generation. Simulation results show that, for problem, outperforms other heuristic algorithms characterized robustness, high success ratio, fast convergence global searching.
