Estimation of the order parameter exponent of critical cellular automata using the enhanced coherent anomaly method.

Abstract

The stochastic cellular automaton of Rule 18 defined by Wolfram [Rev. Mod. Phys. 55 601 (1983)] has been investigated by the enhanced coherent anomaly method. Reliable estimate was found for the $\beta$ critical exponent, based on moderate sized ($n\le 7$) clusters.
