The limit language is defined from limit set and its complexity is studied by using formal language theory. It is proved that this language is not a regular language. This result shows that the dynamics of this cellular automaton is actually complicated.展开更多

Wolfram has become a new branch of cellular automata. In this paper, we obtain two interesting relationships between elementary cellular automata of rules 126, 146（182） and 18, and prove that if the limit language of rule. 18 is not regular, nor are the limit languages of rules 126 and 146（182）.展开更多
文摘In this paper, the limit set of the elementary cellular automaton of rule 22 is considered. The limit language is defined from limit set and its complexity is studied by using formal language theory. It is proved that this language is not a regular language. This result shows that the dynamics of this cellular automaton is actually complicated.

文摘Limit language complexity of cellular automata which is first posed by S. Wolfram has become a new branch of cellular automata. In this paper, we obtain two interesting relationships between elementary cellular automata of rules 126, 146（182） and 18, and prove that if the limit language of rule. 18 is not regular, nor are the limit languages of rules 126 and 146（182）.
