A generator written in Javascript for Elementary Cellular Automata. We call it eca. Made by Mund & Mart for their profielwerkstuk.

eca(rule, options) has one required parameter(the rule),the second parameter is optional. The rule can be a base 10 integer or an binary string. The second parameter is an object. That object can contain a seed. The seed is a binary string. The seed defaults to '1'. You can also determine the width of the eca. The width property defaults to 11. The .genLattice() method generates a new lattice and returns that lattice. A lattice is an binary string. The lattices are saved in the .lattices property. You can also use the .generateLattices(n) method to generate multiple lattices at once. This returns an array with the created lattices.

Examples:

const eca = require('eca')

const thirty = eca(30)
thirty.genLattice() // => '00001110000'
thirty.genLattice() // => '00011001000'
thirty.genLattice() // => '00110111100'
thirty.lattices
// => [ '00000100000', '00001110000', '00011001000', '00110111100' ]

A custom eca:

const custom = eca('00111001', {seed: '1001', width: 4})
custom.generateLattices(3) // => [ '0100', '0011', '1011' ]
custom.lattices
// => [ '1001', '0100', '0011', '1011' ]

npm i eca
