CellularAutomata
Raku package for representation and evolution of cellular automata.
Installation
From Zef ecosystem:
zef install CellularAutomataFrom GitHub:
zef install https://github.com/antononcube/Raku-CellularAutomata.gitUsage 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;

use Graphviz::DOT::Chessboard;
my @mat = cellular-automaton(30,[[1,], 0], 20);
