ndautomata 0.1.2

Multidimensional cellular automata in Python.

ndAutomata

Awesome cellular automata library created by Borja Esteban.

Install it from PyPI

$ pip install ndautomata

Usage

This package is designed in order to create your own automata definitions based on 2 attributes:

• neighbours: List with relative indexes to cell neighbours.
• states: Number possible cell states.

from ndautomata import BaseAutomaton, neighbours

class Automaton(BaseAutomaton):
    neighbours = neighbours.regular(ndim=1, r=1)
    states = 2

Note the automata dimensions are defined with neighbours.ndim.

After you have defined your automaton, you can instantiate automata passing the initial configuration and the rule to the constructor function. Use the module initializers, based on numpy to generate the required arrays passing the number of states and size.

from ndautomata import initializers

rule = initializers.random(states=2, size=[2, 2, 2])
ic = initializers.center(states=2, size=[200])
ca = Automaton(ic, rule)

Note the shape of the rule must always be [states] * neighbours.size.

Plot the cellular automaton using matplotlib or your favorite tool.

import matplotlib.pyplot as plt

plt.rcParams["image.cmap"] = "binary"
plt.matshow([next(ca) for _ in range(100)])
plt.show()

See examples for more detailed use cases and examples on how to generate some plots.
