摘要
为改变元胞自动机模型(CA)局部转换规则与现实世界中事物演化规律的不符,对CA基本构成进行扩展,并讨论扩展后CA的局部转换规则。然后基于扩展CA的原理对初等元胞自动机(ECA)进行扩展,通过ECA与扩展ECA的实验对比分析,将CA与扩展CA进行对比分析,得出结论:扩展CA具有比CA更丰富、复杂的局部转换规则,更能模拟复杂系统的复杂特性;扩展CA模型具有更高的模拟精度。
To change the disagreement between the local transition rule of cellular automata（CA） and the evolving rule of things in real world, in this paper, the CA was extended by adding attri- butions for each cell and macro-factors for cellular space, and the local transition rule of extended CA was analyzed. Then the comparison of CA and extended CA was carried out through compa- ring the Elementary CA（ECA） and extended ECA（extended according to the definition of extend- ed CA）. Two conclusions can been drawn： （1） extended CA has more rich and complex rules than CA, extended CA could simulate the complexity of complex system more well; （2） extended CA has higher accuracy of simulation result than CA model.
