Wireworld is a cellular automaton first proposed by Brian Silverman in 1987. It is particularly suited to simulating electronic logic elements, or "gates", and, despite the simplicity of the rules, Wireworld is Turing-complete.
This is a simple implementation in Python, with a basic GUI.
$ python ww.py source delay
Several samples are provided in the circuits folder. For example, an XOR gate with feeders with half second delay between each frame:
$ python ww.py circuits/xor-generators.txt 500
- Basic window sizing capabilities. The window and block sizes are computed within certain boundaries to accommodate the wireworld (no window resize though)
- Adjustable delay
engine.py: the automatongui.py: a Tkinter GUI
The project does not require any external dependencies.
From wikipedia: a Wireworld cell can be in one of four different states, usually numbered 0–3 in software, modeled by colors in the examples here:
Empty (Black)
Electron head (Blue)
Electron tail (Red)
Conductor (Yellow)
As in all cellular automata, time proceeds in discrete steps called generations (sometimes "gens" or "ticks"). Cells behave as follows:
Empty → Empty
Electron head → Electron tail
Electron tail → Conductor
Conductor → Electron head if exactly one or two of the neighbouring cells are electron heads, or remains Conductor otherwise.
