摘要:
提出了确定的有限元胞自动机的概念,通过对演化构形的惟一性特征的分析,证明了确定的有限元胞自动机的状态演化最终处于稳定状态或者循环状态;具有相同演化结果的状态构成等价关系两个性质.利用初等元胞自动机对其进行了验证,在此基础上,对元胞自动机的四个普遍性分类进行了三个层次的探讨.

Abstract:
Defines a determined finite cellular automata (DFCA) and analyzes its evolution. It is proved that the finally spatial status of a DFCA tends to keep steady or circulating and the status having the same evolution result compose an equivalence relation. These two conclusions are checked by an elementary cellular automata. Furthermore, three levels of discussion are given in order to study the four kinds of general classification of the cellular automata.
