Global optimization method of Web services composition based on QoS
Su Liang · Computer Engineering and Applications Journal · 2007
This paper investigates the QoS-based online global optimization method which can be used in the Web services pre-optimization phase and the replanted Web services composition in the running fault-tolerance phase.Our main contribution is that we propose a method which composites the modified simplex method and the heuristic enumerate method to solve the multi-objective global optimization problem,which makes the convergent rate of searching solution space faster and enhance the optimization level of the target function.
