摘要
Complex Adaptive System (CAS) theory is widely used in social, economic, ecological and other areas recently. Research on the complexity, adaptability and other significant characteristics of CAS is important for better understanding of CAS. By Repast platform, we construct a typical CAS-an ecosystem constituted by the Artificial Life. Through the simulation of the system and analysis of simulation results, we analyze the complexity, adaptability and other characteristics of CAS.
