Abstract:
In this paper five different algorithms are proposed to solve the QoS-aware Web Services Composition (QWSC) problem in ten different search-space sizes and a realistic deadline (a point not covered in many related works). Differently from some related works, statistical techniques are adopted in this paper to ensure more precise results from the algorithms. The results obtained showed that the design of experiments and the performance evaluation can be used to determine which algorithms have better performance according to the different search-space sizes and the estabilished deadline; it is also possible to determine which genetic operators are better suited for the QWSC problem.
