| Abstract: | This paper combined Pareto optimization and genetic algorithm, built a mathematic model to describe the preferential choice of service provider, used the Pareto genetic algorithm to optimize the multi-objective problems, presented the suitable ways of initializing the population, selection, crossover, mutation for the model and got a Pareto optimal set. Also it gave the arithmetic for selecting the solution among optimal set according to the status of service provider. The results of experiments show that this algorithm can make the system resources more efficient than that introduced in reference [3]. |
