TOTALISTIC TWO-DIMENSIONAL CELLULAR AUTOMATA EXHIBITING GLOBAL PERIODIC BEHAVIOR
N. Boccara, M. Röger · International Journal of Modern Physics C · 1999
We have determined families of two-dimensional deterministic totalistic cellular automaton rules whose stationary density of active sites exhibits a period two in time. Each family of deterministic rules is characterized by an "average probabilistic totalistic rule" exhibiting the same periodic behavior.
