Cellular Automata/Information Dynamics


 * Information speed


 * $$ v = \frac{ \Delta x }{ \Delta t } $$

It is defined as the number


 * Speed of light

Is the maximum speed information can travel inside CA.It depends on the size and shape of the neighborhood and it may depend on the direction.

For asymmetric 1D CA (left and right direction)


 * $$ c_L = k_0 $$ $$ c_R = k-k_0-1 $$

For symmetric 1D CA (radious $$r$$)


 * $$ c = r $$
