pyca

Cellular Automata, CA, in Python.

Features

• easy to add new rules, check Rule30
• you can even witch rules during compute
• multiple dimensions universes (1d and 2d) support
• support multiply cell types in one universe
• support customized neighbour search
• unit tests (more is coming)

Get started

1. Clone the code
2. Install libraries: pip install -r requirements.txt
3. Pick a script form example/ folder
4. Magic...

Explore the code

from pyca.universe1d import Universe1D
from pyca.rules.Rules import Rule30
from pyca.observer import plot1d_universe

universe = Universe1D(300)
universe.register_cell_type(Rule30, 'random', prob=0.5)
universe.initialize()
universe.compute(300)
plot1d_universe(universe)

Or for classic rulexxx system, you can just pus a str represent rule for ClassicRule!

from pyca.universe1d import Universe1D
from pyca.rules.BaseRule import ClassicRule
from pyca.observer import plot1d_universe

size = 600
universe = Universe1D(size)
universe.register_cell_type(ClassicRule, 'single', pos=size-1, rule='01101110')  # Rule110 here
universe.initialize()
universe.compute(size)
plot1d_universe(universe)

Concepts

• Universe, contains all the cells, and function to trigger computation
• CellType, rule of the cell is defined here
• observer, way to observe universe, well it can be visual, but it can also be something else, like sounds!

Currently, 2 2D universe is supported, you can define a CA by injecting a new type of CellType.

Road map

• 3D universe
• HyperGraph Universe
• Interactive Observers
• Musical Observers

Rule 0 - Rule 255
