# What is a Cellular automaton?

A Cellular automaton is a special kind of universe: space is divided into a finite number of cells, while time advances in time ‘hops'(t=0,1,2,3,…)

Each cell has a state ( for ex.: ‘Dead’, ‘Alive’, ‘True’, ‘False’, ‘Red’, ‘Blue’). A cell represents a Finite State Machine.

The cells are connected together. A group of connected cells is called a neighborhood/cluster. The state of the cell is affected by the states of its neighbors.

In the common scenario when time changes(for ex. t=1) each cell changes its current state in parallel to the other cells in the automaton.

A cellular automaton could exist in multiple dimensions: 1-D, 2-D, 3-D, …

One could think of a cellular automaton as a multi-agent system. Each cell represents an agent. Global emerging behavior could be observed in result of local interactions between cells.

# Intro: Life-like Cellular automata

Life-like cellular automata are composed of “living” cells. A living cell has two possible states: Dead or Alive.

By default a cell dies except in these cases:

- A cell survives if surrounded by N living neighbors
- A cell comes to life if surrounded by K living neighbors

where N and K are integers (for ex. N=2, K=3)

# Interesting facts:

Life-like automata are able to produce self-replicating patterns.

Life-like cellular automata display emerging behavior – global behavior resulting from local interactions

It is interesting

are there any tutorials for the “cellular automata”?

Very interesting

.

Thanks so much for this article!! FYI you used “it’s” in a few places rather than “its,” which changes the meaning.

nice
