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 not working

I am trying to create a Cellular Automaton based on this. I have managed to do it in a simple way that would follow only rule 90 but when I changed it to accept any rule I did something wrong. This is how the result should…

Cellular automation get non-living neighbours

I'm trying to develop a cellular automata simulation and the problem is I want to get the close neighbours and far neighbours of each cell (illustrated as blue and beige) and determine which cells are dead and using some rules bring them to life. So…

Conway's Game Of Life - Incorrect Algorithm?

The algorithm I created (implementation of Conway's Game of Life's rules) doesn't match Conway's GoL. I've tried just about everything I can do, but it just doesn't match. Additionally, if anyone knows how to make it into an infinite plane or…

Python: Replacing random.random with a .txt list

I'm trying to modify a python script that models a version of Conway's game of life. In which a set of cells in X number of columns and Y number of rows are each given a value that determines if they will switch between two states of active or…

MPI_Exchanging sides of vector between processes

In my code I have an arbitrary number of processes exchanging some parts of their local vectors. The local vectors are vectors of pairs and for this reason I've been using an MPI derived datatype. In principle I don't know how many elements each…

How to interpret Turing Machine illustrations on p79 of Stephen Wolfram's “A New Kind of Science” book?

I am reading Stephen Wolfram's "A New Kind of Science". At present, I cannot understand how the cellular automata illustrations on p79 are created. In the patterns, the active cell, representing the head, appears to change orientation between up and…

Multi agent system vs Cellular Automata

Could someone describe the difference between MAS and CA? Is MAS derived from CA or do they share similar principles, or are they completely different entities that are used together to simulate complex behaviors?
