【摘要】 Logistic混沌映射在真实轨道中迭代真值在最低数字位是5的时候,迭代真值高数字位部分表现出随机特性,迭代真值低数字位表现出线性递增的公共数字位.实验分析显示,在绝对精度条件下,混沌真实轨道保持随机性和公共部分稳定的结构特征,在有限精度条件下,迭代值随机性受计算精度影响很大,公共部分只能通过低位迭代法获取.更多还原

【Abstract】 The iterative real value of the Logistic chaotic map in true orbits exhibits obvious regularity when the lowest digit position is 5.The high digit part of its iterative real value shows random characteristics.The low digit part of its iterative real value represents a linearly increasing common digit positions.Experimental analysis shows that under absolute accuracy conditions,the chaotic real orbit keeps randomness and the structural characteristics of the common part are stable.Under finite accuracy conditions,the randomness of the iterative values is greatly affected by computational accuracy,and the common part can only be obtained through the iteration method with low positions.更多还原
