Cellular Automata

This Python package implements 2-d cellular automata by using pytorch. This package includes two types of 2-d cellular automata:

1. Totalistic CAs: cells update by the sum of its neighbors' (including it self) states;
2. Outer-totalistic CAs: cells update by the sum of its neighbors' (NOT including it self) states AND the cells' state;

Basic Usage

Game of Life

import CA
import matplotlib.pyplot as plt


s = CA.GameOfLife(init_state=CA.random_init(150), steps=150)

plt.figure(figsize=(8, 8))
plt.imshow(1-s, cmap='gray')
plt.show()

Totalistic CAs

import CA
import matplotlib.pyplot as plt


s = CA.TotalisticCA(30, init_state=CA.random_init(150), steps=150)

plt.figure(figsize=(8, 8))
plt.imshow(1-s, cmap='gray')
plt.show()

Outer-totalistic CAs

import CA
import matplotlib.pyplot as plt


s = CA.OuterTotalisticCA(20, init_state=CA.random_init(150), steps=150)

plt.figure(figsize=(8, 8))
plt.imshow(1-s, cmap='gray')
plt.show()
