Abstract: In the process of QoS-sensitive business, the user not only cares about whether the function of the process will be finished successfully, but also pays great attention to the QoS of the whole process. Thus, how to make a choice among the candidate web services so that the selected ones can not only finish the assigned task and conform to the local restriction, but also can cooperate with other web services and optimize the QoS of the process, becomes a key problem. In order to solve this problem, an approach based on the generic algorithm was proposed. The experimental results show the effectiveness of this method.

Key words: generic algorithm , QoS, Web service composition
