Cellular Automata

Command Line Tool

Mainly for testing runtime of the algorithm, without the disturbance of GUI packages and settings.

  • Normal

    Uses algorithm the same as the one used in GUI version. Compatiable to all patterns but can be relatively slow.

  • Hashlife

    Use quad tree to divide the canvas and has map to store existing patterns. Fast but require large memory especially for larger patterns.

To run, execute:

$ python3 normal.py

or

$ python3 hashlife.py

Then input .cellauto files and the number of steps for the simulation, or type QUIT to stop:

Input the filename or type "QUIT" to stop:
Patterns/breeder.cellauto
Input number of steps
100000

The program will then output the runtime for the simulation.

GUI

GUI tools for cellular automata.

overview

To run, execute

$ python3 __main__.py

Current version supports following functionalities:

  • Mode Selection

    Click Menubar -> Mode to select modes. Click "Customize Rule" and select an number within range [0, 255] to customize the rule for Sierpinski triangle.

    customize_rule

  • Sizing

    Canvas can be resized through Menubar -> Canvas -> Set Unit Number.

    The view of the canvas can be zoom in or zoom out by mouse wheel.

  • Graphing

    Create new cells by left clicking and delete by right clicking.

    Drawing a line of cells through continues left clicking.

    Randomly generate the pattern through Menubar -> Canvas -> Random.

    Clear the canvas by Menubar -> Canvas -> Clear or shortcut Ctrl + Tab.

  • Simulation

    Run one step of simulation by typing Return.

    Run continuous simulation by typing Whitespace. Type again to stop.

    Increase simulation speed (reduce time between every 2 steps) by typing "]".

    Decrease simulation speed (increase time between every 2 steps) by typing "[".

    Operations above can also be found at Menubar -> Control.

    Click Menubar -> Canvas -> Turn Back to return to the inital pattern before the simulation started.

    Current simulation status/info can be found at the lower side of the window, including cell population, step number since the start of simulation, time interval between every 2 steps, and the simulation mode.

  • File Saving and Reading

    Open a .cellauto file by clicking Menubar -> File -> Open or shortcut Ctrl + O

    Save intial canvas before the simulation by clicking Menubar -> File -> Save Initial or shortcut Ctrl + S.

    Save current canvas by clicking Menubar -> File -> Save Current or shortcut Ctrl + Shift + S
