Fig. 8. Integrated information peaks at the edge of chaos.

(a) Sample runs from a random 6-color, range-2 cellular automaton with different λ values, starting from a blank tape with 20 randomized cells in the middle. The parameter λ corresponds to the fraction of non-blank cells in an automaton’s update rule. (b) Integrated information Φ^R peaks at an intermediate level of λ. (c) When plotted against Δλ, the distance from a transition event, all runs align on a similar Φ^R profile.
