Personalized service composition based on multi-strategy discrete differential evolution in mobile internet

With the popularity of mobile internet technology,people are not satisfied with the service that provides a single function and hope to gain the personalized or composition service according to their needs.A muti-strategy discrete differential evolution(MDDE) algorithm applied in Web service composition was put forward.The algorithm,which adopts a random selection framework and multi-mutation strategies with different properties,was the balance of search ability and convergence speed.The results indicate that the proposed algorithm is better than traditional differential evolution algorithm in solving Web service combination optimization problems in terms of the solution quality and stability.
