基于参数自适应差分进化算法的Web服务组合
Web Service Composition Based on Differential Evolution Algorithm with Adaptive Parameters
摘要
Abstract
In order to accurately reflect the user satisfaction with the quality of service experience,we put forward a Web service composi-tion model based on QoE (quality of experience) and solve it by algorithm of differential evolution(DE).Firstly,we establish a fuzzy expert evaluation system based on QoE,by which the parameters are transformed into QoE mathematical expression.In the second place, on the basis of the standard DE,the chaos initialization and parameter adaptive mechanism are introduced.Using the characteristics of cha-os and DE parameters not only can overcome the shortcomings of falling into local optimal for DE,but also improve the performance and the ability to find the global optimal of DE,as well as its stability and reliability.Finally,it is made a comparison with PSO,ACO,the standard DE and Chaotic initialization DE.The experiments show that the parameter adaptive DE in Web services on combinatorial opti-mization problems has the characteristic of fast convergence and high stability.关键词
