The XOROR sequence

Cellular Automata are truly fascinating. The ones that are usually talked about are the binary ones, i.e., the ones representable by a number. However, those, in my opinion, have been done to death. ...

Electrons bouncing in a wire

Imagine a "wire" that has n spaces. Imagine further that there are "electrons" in that wire. These electrons only live for one unit of time. Any spaces in the wire that are adjacent to exactly one ...

Bacterial expansion

Colonies of bacteria labelled 1 through 9 live on a segment of equally-spaced cells, with empty cells indicated by 0 0 0 2 0 0 0 1 2 0 0 3 3 0 0 Every second, each colony spreads to adjacent empty ...

Digital Cellular Automata

Write a program or function that takes in an odd positive integer N and a string of decimal digits (0123456789). The string represents a ten-state one-dimensional cellular automaton. Each digit ...

Shortest Wireworld [duplicate]

Wireworld is fun for the whole family! Your goal is to create a Wireworld implementation in the shortest amount of code possible. A Wireworld cell can be in one of four different states, usually ...

Identifying Sequences for Cellular Automata

Background For the purposes of this challenge, an n-state cellular automaton is simply a binary function f that takes two numbers from the state set {0, 1, ..., n-1} as inputs, and returns another ...

Emulate Rule 110 with Conway's Game of Life (or vice versa)

Can you find initial conditions for either Rule 110 or Conway's Game of Life to emulate the other? That is, produce output (in any form, not necessarily the familiar pixel grid) which corresponds ...

Create a universal two-dimensional cellular automaton cell using two-way universal logic processors

In Conway's Game of Life, a cell is in a state of either on or off, depending on the on-and-off state of the eight cells surrounding it. We can simulate this using a logic gate network with some sort ...

Implement the Game of Life on Anything but a Regular Grid

Conway's Game of Life is (almost) always played on a regular square grid, but it doesn't need to be. Write a program that implements the standard cell neighboring rules from Conway's Game of Life on ...

Simulate Rule 110

Rule 110 is a cellular automaton with some interesting properties. Your goal is to simulate a rule 110 in as few characters as possible. For those who don't know, rule 110 is simulated line by line. ...

Build a working game of Tetris in Conway's Game of Life

Here is a theoretical question - one that doesn't afford an easy answer in any case, not even the trivial one. In Conway's Game of Life, there exist constructs such as the metapixel which allow the ...

Simple redstone simulator

Redstone is a material in the game Minecraft, and it is used for many complex contraptions. For this program, you will only need to simulate three items: the redstone wire (noted with R), redstone ...

Simulate the Wireworld cellular automaton

Wireworld is a cellular automaton that was designed to be resemble electrons flowing through wires. Its simple mechanics allow the construction of digital circuits. It has even permitted the ...
