本文分析了具有复杂时空动力学的两个耦合初等元胞自动机的动力学。以概率p为特征的耦合机制是随机的。从数值模拟中，我们发现两个元胞自动机的完全同步发生在临界值p处。这种转变可以用差分自动机的演化近似半解析描述，并且可以在对称和非对称耦合中找到。本文认为元胞自动机在耦合作用下的行为可以启发对其个体动力学的分类。@s1063 - 651 x ~ 98 !51407 - 9 #
We analyze the dynamics of two coupled elementary cellular automata with complex spatiotemporal dynamics. The coupling mechanism, characterized by a probability p, is stochastic. From numerical simulations, we find that a sharp transition to full synchronization of the two cellular automata occurs at a critical value of p. This transition admits an approximate semianalytical description in terms of the evolution of the difference automaton, and is found both for symmetric and asymmetric coupling. It is argued that the behavior of cellular automata under coupling may inspire a classification of their individual dynamics. @S1063-651X~98!51407-9#
