Synchronization and control of cellular automata

Franco Bagnoli, Raul Rechtman
We study the problem of targeted synchronization of stable chaotic extended systems, i.e., systems which are not chaotic in the usual sense, but are
unpredictable for finite perturbations. Examples are cellular automata, which are completely discrete dynamical systems. We show that the usual approach may lead to counter intuitive results, but that it is possible to exploit the characteristics of the system in order to reduce the distance between two replicas with less control.
