基于改进遗传算法的QoS感知Web服务组合
Web Service Composition Supporting QoS Based on Improved Genetic Algorithm
摘要
Abstract
Even or random selecting is the common method used for generating initial population in genetic algorithm, however, the average fitness of the population generated by this method is low, and it is hard to ensure the searching efficiency of algorithm. In this study, propose a novel genetic algorithm (GA) for handling QoS-aware Web service composition, combining two initialized algorithms with GA at initialization stage to improve the algorithm effectiveness. Besides, build a path-template and variable length chromosomes service composition solution, for template paths will make the work easy and variable length chromosomes can support multi-path QoS-aware service composition. The superiority of the algorithm is analyzed theoretically and its effectiveness is demonstrated by experimental results.关键词
