Deterministic cellular automaton rule emulating 2D diffusion

Abstract

Files defining 8-state cellular automaton emulating diffusion in 2 dimensions. Rule definition is in golly's .rule format. Sample initial pattern is included. Details of the rule are described in: H. Fukś. Four state deterministic cellular automaton rule emulating random diffusion. In B. Chopard, editor, Cellular Automata, ACRI 2022, LNCS 13402, pages 142--152.
