Population Diversity and Algorithm Realization of Sustainable HFC Model

HFC (Hierarchical Fair Competition) model is a kind of sustainable EA based on hierarchical search. On the basis of studying the sustainable evolutionary theory of HFC model deeply, in the HFC model the admission and export threshold are proposed to divide all fitness grade. And it is suggested that both static and active thresholds is used by the complication of different problems. In addition, through analyzing the parameters and topology space of HFC model, it is gained to the organize framework and detailed algorithm structure. Finally, it is proved by exercise that HFC model can maintain the diversity of population and assure the fair competition during individuals effectively.
