Principle of Computational Equivalence


Can simple programs produce very rich and complicated behaviors? Could it be possible that all of the amazing things we see in the universe be the result of a simple program? That would be very exciting to have a program that is an ultimate precise model of our universe. If you run it long enough it would produce complex models. Stephen Wolfram asks how would this program be like.

The principle of computational equivalence says that “systems found in the natural world can perform computations up to a maximal ("universal") level of computational power, and that most systems do in fact attain this maximal level of computational power.”

The structure of a system need not be complicated for its behavior to be highly complex. Cellular Automata (e.g rule 30) can provide an example to provide models for a wide variety of complex natural systems. Even Turing machine model with one cell updating would be a model for complex behaviors. Universal machines that can do any kind of computations have many implications for natural science too.

It is easy to see the reflections of the Computational Equivalence Principle in Richard Dawkins Biomorphosis, Thomas Ray’s Tierra project, and Karl Sim’s virtual creatures.
