Topological Structure and Evolution Nature of Competitive System Based on Reverse Preferential Competition

Using the system architecture analysis method,this paper constructs a reverse preferential competition model of competition system in order to reveal the systemic structural features and evolution nature.Analysis and simulation results show that driven by the reverse preferential competition mechanism,large number of nodes with low competitiveness will be quickly eliminated from competition system,and that long-term existence of the system macro-structure has shown a strong time-independent state and stability structural features.At the same time,this study confirms that different micro-competition mechanisms will show different characteristics of macro-structure and evolution nature of systems.In addition,this study depicts a competition phenomenon of "survival of the fittest" prevailing in the objective world.
