Questions tagged [cellular-automata]

A cellular automaton is a discrete model studied in computability theory.

By wikipedia,

A cellular automaton is a discrete model studied in computability theory, mathematics, physics, complexity science, theoretical biology and microstructure modeling.

A cellular automaton consists of a regular grid of cells, each in one of a finite number of states, such as on and off (in contrast to a coupled map lattice)

How can I iterate over a function

I'm simulating forest-fire, and one of my tasks is to plot the density of trees vs those currently burning and empty plots. I have the disparate parts, however I need assistance in putting them together as I can't work out how to put my code…

Why does my falling sand simulator have weird behaviour?

I've been spending the last two days trying to figure out why my falling sand simulation does weird things it obviously shouldn't. I have moved from 2D Arrays to HashSets and finally to ConcurrentSkipListMap, with my own Point class as keys, and…

Swapping multidimensional arrays in C

I'm doing a code for Elementary Cellular Automata and trying to get it more efficient. One of my goals is to combine it with the Game of Life Cellular Automata in the same array, computing one half values by the Elementary Wolfram rules, and the…

Errant segments in cellular automata encryption algorithm

I've been implementing a paper that is targeting IoT encryption using a 64-bit block cipher via elementary cellular automata. The paper is in the repository/linked in the README. I am trying to verify that an implementation of this algorithm…

Finding second-order cellular automaton

I've been generating cellular automaton with the following Python code. I'm trying to find reversible second-order automata for the second phase of the project but am having trouble understanding the core concept. Would I map the time steps of the…

Map generation by Cellular Automata not working

I have been developing a tile game and I implemented Cellular Automata for Random Map generation but it seems to not work properly. The steps using which I generate a Map are as follows: *First I generate noise in my Map using the following…

Cellular Automata returns all 0s [PYTHON]

I have written a program (see below) as an implementation of cellular automata in python. When I run the program, I receive a pattern of random seeded noise and the new pattern that has been run through the program. The "." are zeros and the "#" is…

How can I annotate a cell grid in matplotlib?

first, I'm sorry if my question seems really simple, but I am a python beginner. I've been writing for a while this code modeling the spread of an epidemic using cellular automata. The code is the following : import matplotlib.colors import numpy as…

Conway's Game of Life in Python generates random long lines in what should be dead zones

Decided to try my hand at implementing Conway's Game of Life in Python. Wasn't going for a particularly efficient implementation or anything, just wanted something that works. My board is a 2 dimensional list, each cell has a 1 or 0 to denote…

Python - numpy arrays - Abelian sandpile

I'm trying to do the Abelian sandpile model using a simple numpy array. When a 'pile' is 4 >=, then it collapse among its neighbors. I understand how the "gravity" thing works, but I can't think of a way of making it. Here's the code to make my…

std::vector VS std::string, which one is faster?

I've been messing around with cellular-automata for a while now, and the way I chose to implement them is by creating a 2D vector of cells, where each cell was initially a vector of integers itself (because I want each cell to store more than one…
