摘要: Finding optimal solutions for QoS-aware Web service composition with conflicting objectives and various restrictions on quality matrices is a NP-hard problem. This paper proposes the use of multi-objective evolutionary algorithms (MOEAs short) optimisation. More specifically, SPEA2 introduced to achieve goal. The algorithm good at dealing combinational optimisation problems. Experimental results reveal that able approach Pareto-optimal front well spread distribution. Pareto approximations provide different trade-offs, from which end-users may select better one based their preference.
