Three Favorite Cellular Automata

Abstract

Cellular automata (CA) are attractive visually and offer strikingly simple definitions for well motivated models that can produce complex behavior. My study and research with CA began in earnest the 1990’s and since then I have explored many interesting automata. My research on CA has included models with the symmetry of snowflakes, self-organizing waves produced by prey-predator models, and cyclic CA on various nonrectangluar lattices and in three dimensions. In addition, I have explored many local image processing techniques that are essentially CA for applications to smoothing and enhancing images, and creating Vorinoi tilings and other patterns.
