F. Jimenezmorales et Jj. Luque, COLLECTIVE BEHAVIOR OF A PROBABILISTIC CELLULAR AUTOMATION WITH 2 ABSORBING PHASES, Physics letters. A, 181(1), 1993, pp. 33-38
A cellular automaton, with two states per site and with a probabilisti
c behaviour for the transition, is studied. With the selected rule the
automaton has two absorbing phases. A reanimation factor epsilon is i
ntroduced along with a factor p related to the probability of the tran
sition. Results of a mean-field approximation are compared with numeri
cal simulations of the automata showing the existence of collective be
haviour for some values of p and epsilon.
