The Application of Ant Colony Algorithm in Web Service Selection

As an intelligent algorithm with the mechanism of positive feedback, the ant colony algorithm is useful in solving the optimal problem. Web service selection is the foundation of the Web service composition which is one of the most important ways to satisfy the users´ personalized requirements. Firstly, analyzed the problem of Web service selection based on expounding the basic principle of ant colony algorithm and transformed the problem of Web service selection driven by QoS into the problem of finding the shortest path. Secondly, given the steps for solving the problem of Web Service selection based on the ant colony algorithm and contrasted the results under different parameters. Lastly, verified the validity of ant colony algorithm in Web Service selection.
