A method to discern complexity in two-dimensional patterns generated by coupled map lattices

Complex patterns generated by the time evolution of a one-dimensional digitalized coupled map lattice are quantitatively analyzed. A method for discerning complexity among different patterns is implemented. The quantitative results indicate two zones in parameter space where the dynamics show the most complex patterns. These zones are located on the two edges of an absorbent region where the system displays spatio-temporal intermittency. (c) 2005 Elsevier B.V. All rights reserved.
