Replicator (cellular automaton)

From HandWiki
Short description: Type of pattern that infinitely produces copies of itself
The evolution of the replicator in Highlife.

In cellular automata, a replicator is a pattern that produces copies of itself.

In the one-dimensional Rule 90 cellular automaton, every pattern is a replicator.[1] The same is true in the life-like cellular automaton rule Replicator (B1357/S1357).[2][3]

Highlife (B36/S23) rule has a simple replicator.[2]

On November 23, 2013, Dave Greene built the first replicator in Conway's Game of Life (B3/S23).[4][better source needed]
