Abstra ct. Stephen wolfram int roduced the use of cellula r au tom ata. as mod els of complex sys tems and proposed a clas sification of th ese automata based on th eir st a t ist ical ly observed behavior. We invest igate various properti es of these classes; in part icular, we as k wheth er certain prop erties are effective, and we obtain several somewhat surpri sing result s. For examp le, we show th at it is undecidable wheth er all th e fini te configu rations of a given cellular automaton…

Cellular Automata with Regular Behavior

It is proven that CA with code 0110 behave regularly on seeds belonging to the set I = EO-r where E = {a, I} and r = EOUEOlll E O, where e, is some constant depending on r.

Complex Chaotic Behavior of a Class of Subshift Cellular Automata

A new class of cellular auto mata is identified that is characterized by shift like dynamics (simple and complex subshift rules); these cellular automata correspond to t he asymmet ric sit uations and they are chaotic dynamical syst ems.

Universal Cellular Automata and Class 4

It is shown that the identification of the Wolfram class depends crucially on the set of initial conditions used to simulate the given CA, indicating that a description of complex systems and information dynamics may need a new framework for non-equilibrium statistical mechanics.

Classsification of Cellular Automata

The Wolfram Classes Wolfram proposed a heuristic classification of cellular automata based on observations of typical behaviors, which comprises four classes: evolution leads to trivial configurations, to periodic configurations, evolution is chaotic, evolution lead to complicated, persistent structures.

Irreducibility and Computational Equivalence

It is shown that systems in Class III are indeed capable of computation and that there is no reason to believe that they are unable, in principle to reach Turing universality.

Monomial Cellular Automata

This work investigates the dynamical features of monomial cellular automata, whose next-st ate is given as a product of t he neighb orin g states, and analyzes monomials of higher degree via a superpos it ion prin ciple.

Computation theory of cellular automata

The sets of configurations generated after a finite number of time steps of cellular automaton evolution are shown to form regular languages and it is suggested that such undecidability is common in these and other dynamical systems.
