Simulate One Dimensional Finite Automata in Terminal

Usage

$python3 eca.py <width> <rule> [-r] [-s0 <sym>] [-s1 <sym>] [-eth] [-d <delay>] [-p <pattern>]

<width> int >= 1 (width of automaton)

<rule> int 1-256 (cellular automaton to simulate)

-r randomize initial state (default sets all cells to 0 except rightmost)

-s0 <sym> display 0 cells as <sym> (default = ' ')

-s1 <sym> display 1 cells as <sym> (default = █)

-eth show rule 110 background ether as different color (mostly-accurate)

-d <delay> set delay between steps to <delay> seconds (default = 0.01)

-p <pattern> supply initial state via string pattern. {0,1,a,b,c,B,E,x}* (see eca.py for pattern defs)

Examples

600 cell Rule 110 with default parameters:

$python3 eca.py 600 110

600 cell Rule 90 with randomized initial state:

$python3 eca.py 600 90 -r
