摘　　要：分析了一类基于遗传算法无限种群模型的协同进化系统,在此基础上构造了一类新的协同进化系统,并推导出了它在单基因位情况下的动力方程。对新系统在稳态情况下的复杂动力行为进行了分析,通过相图、分岔图和Lyapunov指数谱图,严格地证明了该系统具有混沌特性。A co-evolution system was analyzed based on infinite population model of the genetic algorithm. According to the analytical results, a new co-evolution system is constructed, and the iterative equations of the dynamical system model of the co-evolution system were derived in one-bit case. The complex behaviors of the system in steady state were investigated by phase portraits, bifurcation diagrams and Lyapunov-exponent spectrum. It is shown that the co-evolution system is a chaotic svstem.
