多米诺元胞自动机的三层描述

Three-level description of the domino cellular automaton

Zbigniew Czechowski, Mariusz Białecki

摘要:

受气体运动论方法的启发,提出了元胞自动机的微观、介观和宏观三个层次的描述。为了提供一个分析处理一个简单的多米诺元胞自动机雪崩。导出了平衡态中密度、团簇、雪崩等参数的精确关系式。看来,一些关系是近似有效的偏离平衡,所以适当的伊藤方程可以构建。该方程在宏观水平上提供了一些变量的时间演化描述。研究结果还表明,动机的伊藤方程(从时间序列数据)的建设过程中应用到自然时间序列。

英文摘要:

Inspired by the approach of kinetic theory of gases, a three-level description (microscopic, mesoscopic and macroscopic) of cellular automaton is presented. To provide an analytical treatment a simple domino cellular automaton with avalanches was constructed. Formulas concerning exact relations for density, clusters, avalanches and other parameters in an equilibrium state were derived. It appears that some relations are approximately valid for deviations from the equilibrium, so the adequate Ito equation could be constructed. The equation provides the time evolution description of some variable on the macroscopic level. The results also suggest a motive for applying of the procedure of construction of the Ito equation (from time series data) to natural time series.
