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)

New to C++, "EXC_BAD_ACCESS" error I don't understand

I am attempting to translate a 2 dimensional cellular automata from Processing to openFrameworks (C++). I have written classes for the cells and for the game of life functionality. The application builds successfully but crashes immediately with the…

Udacity CS101: Elementary Cellular Automaton in Python

Can anyone tell me what the issue with my code is (the line with "num" it seems). I'm getting string index out of range, but in an almost identical chunk of code it seems to work. If there's some code I can look at in python I'd love to see links…

Evaluation of arithmetic expressions with a cellular automaton

Stephen Wolfram talked about this thing called cellular automaton. The idea was building what are seemingly complex systems from simple rules and starting configurations. Some examples such as Milton Bradley's game of life are demonstrated in this…

Numpy Array object converting to List object in function?

I'm attempting to create a one-dimensional cellular automata. For a given rule (between 1 and 255), the number is converted into the corresponding 8-digit binary number and paired to all 8 possible combinations of 0's and 1's. The code seems to…

For loop that evaluates all values at once?

So i have a cellular automaton, where i can place pixels on an image and they just move down one pixel each "tick". Now the problem is since the for loop is like this: for(int x = 0; x < 100; x++){ for(int y = 0; y < 100; y++){ //Check if…

What's wrong with my (Conway's Game Of) life?

I tried to write an OOP implementation of Conway's Game of Life in processing. However, it seems to be some other sort of automaton. Interesting, but not what I was going for. I can't find any problems with my code, that's what I'm hoping you can…
