Combined with the advantages of the genetic algorithm,social cognitive optimization and cultural algorithm,this paper devised a new hybrid bionic intelligent algorithm—genetic-cultural-social( GCS) cognition algorithm according to the evolution of the human social intelligence. It gave the algorithm model and calculation process of GCS,and defined the key functions in GCS. Finally,it applied the GCS algorithm to solve the problem of QoS-aware cloud services optimal composition. Experimental results indicate...
