摘要
介绍了细胞自动机的基本思想,利用随机指令序列充当“外场”,控制一维细胞自动机中运行多种演化规则,结果发现多种演化规则的运行有利稳定的本地自组织结构的形成。随时间缓慢变化的随机指令序列会造成自组织结构的逐步消亡;控制运行规则的循环序列会使本地稳定的周期模式的数目减少,显露出模式过滤效应。
This paper presents the fundamental ideas of cellular automata. With a random sequence or a periodic sequence as an 'xternal field', two or more rules operate in cellular automata. The results show that this practice helps the growth of stable local structures. The random sequence as a time-varying instruction causes the self-organizing structures to die out gradually, while the periodic sequences as instructure cause the modes of the stable structure decrease and seem to exhibit effects of the filtering mode.
