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)

Cellular automaton doesn't make new cells

I'm trying to make a program that is able to create every kind of cellular automatons, such as Conway's game of life and everything else too. The graphic implementation works perfectly already, so I wouldn't waste your time with that (especially…

game of life cellular automata using c++ vectors in openframeworks

I am building a game of life CA in C++ (openFrameworks). As I am new to C++ I was wondering if someone could let me know if I am setting up the vectors correctly in the following code. the CA does not draw to the screen and I am not sure if this is…

Local, low-volume message passing for massively distributed cellular automata

I'm working on developing a simulation using massively distributed cellular automata. Cell simulations are distributed across nodes and coordinated using ZooKeeper. Persistent data is stored in Riak. The cellular automata themselves are written in…

2D Cellular Automata for tile based water

I have been trying to implement 2D tile based water into my game. I started out making the tiles appear on screen etc. I have a drawing function that draws each tile type. The problem I'm having is that when I call this function the Tiles that are…

Hydrodynamics on cellular automata (FHP, etc)

I am looking for CA-based fluid dynamics software like this Implementation of FHP model in Nvidia CUDA technology, but still no luck. I want to "play" with those simulations myself and at least read some related papers. It is even better, if…

Speeding up a Cellular Automata

Is it possible, with some sort of algorithm or something like that, to speed up a cellular automata? I'm using a Conway's Game of Life implementation made in XNA and it works perfectly, but the problem is that when I use a grid larger than 128x128…

Analyzing the Probability of Passenger Exit Preference in Emergency Evacuations

I'm working on an evacuation project where I'm assessing the likelihood of a passenger selecting one exit over another based on the proximity of people in the exit area. However, I'm encountering an issue where the sum of the two probabilities…

Color coding for Cellular Automation Model in R doesn't work properly

I am trying to write a basic Cellular Automation Model to model social contamination. The code itself seems to work fine and so does the plotting of images. For any x and any y the values in [x,y,3] will either be "0", "0.5", "0.75" or "1". Using…
