The rule number of a Less-Equal-Greater Cellular Automata (LEG CA) determines how a cell's value changes in relationship to its immediate neighbors. The plot normalizes the values so they are displayed in the same gray range. The specific relationship between a cell and its neighbors is whether the center cell is less, equal, or greater than each of its two neighbors, making a total of nine conditions. Unlike a usual cellular automaton, the states can take arbitrary values, especially since the update rule involves addition.
Rule 5949 partitions random real initializations into subsequences which evolve by repetition of short cycles.
