An Information-Based Classification of Elementary Cellular Automata

for each rule, shown for two different inputs: single cell (a) (either one black cell or one white cell) and random (b). Equivalent rules are represented by a common marker. The association of equivalent inputs with equivalent rules is chosen heuristically as the one that maximizes the averaged TE. The dashed line corresponds to the highest value of for any Wolfram Class I or II rule. Individual markers are shown only for Wolfram Classes III (black) and IV (orange) rules.
