Zengzhi Li · Beijing Youdian Xueyuan xuebao · 2009
A global optimal algorithm based on particle swarm optimization(PSO) is presented to resolve services selection with quality of service(QoS) global optimal in web service composition.This method will transform a web service selection global optimal problem into an optimization problem based on web service QoS.This algorithm is utilized multi-objective particle swarm optimization intelligent optimization principle to produce a set of optimal Pareto with constraint principle by optimizing multi QoS parameters simultaneously.Experiments show the feasibility and efficiency of this algorithm.
