R. Feldberg et al., RECURSIVE DEFINITION OF GLOBAL CELLULAR-AUTOMATA MAPPINGS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(2), 1994, pp. 1699-1711
A method for a recursive definition of global cellular-automata mappin
gs is presented. The method is based on a graphical representation of
global cellular-automata mappings. For a given cellular-automaton rule
the recursive algorithm defines the change of the global cellular-aut
omaton mapping as the number of lattice sites is incremented. A proof
of lattice size invariance of global cellular-automata mappings is der
ived from an approximation to the exact recursive definition. The recu
rsive definitions are applied to calculate the fractal dimension of th
e set of reachable states and of the set of fixed points of cellular a
utomata on an infinite lattice.
