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.
