摘要：There are number of similar functional Web services are available. Trusting to find the most appropriate services from the similar functional available services is an issue. Web service composition is a new software development paradigm, and can done service oriented computing successfully. Web services composition problem can solve with optimization algorithms with QoS. The preference of various QoS of compound service is users wishes. We have proposed the services composition algorithm based on quality of services for various optimization algorithms. In this paper, to identify the best web service, the various optimization algorithms such as PSO algorithm, Cuckoo search and Cuckoo modified algorithm, Gravitational search algorithm and Intelligent water drop algorithm are used and compared. The experimental comparison result shows the best algorithm for web service composition is based on the access rate, speed of the system. This paper presents the QoS calculation of non functional requirements such as availability, response time, reliability and access rate.
