CellularAutomata

Raku package for representation and evolution of cellular automata.

Installation

From Zef ecosystem:

zef install CellularAutomata

From GitHub:

zef install https://github.com/antononcube/Raku-CellularAutomata.git

Usage examples

Two steps of Rule 30 over a specified array:

use CellularAutomata;

cellular-automaton(30, [1, 0, 0, 0, 0, 0], 2)

# [[1 0 0 0 0 0] [1 1 0 0 0 1] [0 0 1 0 1 1]]

Four steps of initialization specification:

.say for cellular-automaton(30, [[1,], 0], 4)

# [0 0 0 0 1 0 0 0 0]
# [0 0 0 1 1 1 0 0 0]
# [0 0 1 1 0 0 1 0 0]
# [0 1 1 0 1 1 1 1 0]
# [1 1 0 0 1 0 0 0 1]

Show the table of rule 90;

rule-table(90, method => Whatever); # method takes also 'text' and 'html' 

# ■■■  ■■□  ■□■  ■□□  □■■  □■□  □□■  □□□
#  □    ■    □    ■    ■    □    ■    □

Show rules of rule 90:

use CellularAutomata::Utilities; 
cellular-automaton-from-number(90)

# ((1 1 1) => 0 (1 1 0) => 1 (1 0 1) => 0 (1 0 0) => 1 (0 1 1) => 1 (0 1 0) => 0 (0 0 1) => 1 (0 0 0) => 0)

Plot the array of 20 steps of Rule 30:

use Graphviz::DOT::Chessboard;

my @mat = cellular-automaton(30,[[1,], 0], 20);
dot-matrix-plot(@mat, :9graph-size, :0tick-font-size, :0tick-offset):svg
