Web service selection based on genetic algorithm with tree dual-structure code
基于树型二重结构编码遗传算法的服务选择

A concept of syntactic business process tree for Web service was proposed. And considering the characteristics of service global selection based on QoS, a genetic algorithm with tree dual-structure code for Web service global selection named GATD was studied. This algorithm was established on syntactic business process tree for Web service (SBPT4WS) and dealt with restriction conditions with dual-structure code. And it can not only effectively select service resource meeting users' QoS requirements, but also preferably support rapid replanning on service executione.
