    abstract = {With the drastic increase in the availability of functionally similar web services, the users take the
herculean task of selecting the apt service that suits his needs. The services are although functionally similar,
they differ with respect to their non functional parameters, in the name of Quality of Service (QoS). But still,
dynamic optimal selection of services can be made possible by getting user preferences and by the use of
computational intelligence techniques. QoS are analyzed and it is designed at the middleware to implement web
service selection and composition. In this study, Improved Gravitational Search Algorithm (IGSA) is proposed
to solve dynamic consumer needs and various QoS parameters are considered for composition of services. The
results indicate that the proposed method shows improvement when compared with other methodologies such
as Hybrid Intelligent Water Drops (HIWD) algorithm and Gravitational Search Algorithm (GSA).}
