Order, Complexity and Chaos in one-dimensional Cellular Automata

( From the Internet DDlab gallery of Andrew Wuensche )

Space-time patterns are shown. From an initial one-dimensional configuration of cell states the Cellular Automaton proceeds its way along discrete time-steps according to a RULE. In these particular cases the neighborhood of each cell (i.e. its ' wiring') consists of five cells (itself included) : k = 5. The size of the system is 900 (n = 900), which means that the system consists of a row of 900 cells which are updated after every discrete time-step.
We must read each space-time pattern from top to bottom (In the displays of these space-time patterns, all previous (one-dimensional) patterns remain displayed, so that we can easily see the evolution of the system).

Directly following each Space-time pattern of Ordered, Complex and Chaotic CA's, the respective Basin of Attraction Fields (of Ordered, Complex and Chaotic CA's respectively) are shown, but in this case for systems only consisting of sixteen cells (n = 16). This is because for larger systems it becomes practically impossibe to compute their Basins of Attraction Fields. See the pictures below.
