Santa Fe CSSS95 Picture #1

This is a one-dimensional cellular automata. This is done with real numbers rather than discrete values for the states, and to make the math simple I did all of the arithmetic "mod 1". In this picture, black represents 1.0 and white represents 0.0 (which is the opposite of the way most people think about these things).

The initial condition is the top row of cells, which was set randomly (but is not actually displayed in this clipping, from the middle of a larger CA run). The update rule was: a_n(T+1) = 0.496 a_n(T) - 0.380 ( a_(n-1)(T) + a_(n+1)(T) )
