Upper critical dimension of Kauffman cellular automata
S P Obukhov, Dietrich Stauffer · Journal of Physics A Mathematical and General · 1989
Random Boolean networks on nearest-neighbour d-dimensional lattices are argued to belong to the universality class of directed percolation with quenched disorder in d+1 dimensions. Hansen's computer simulations for d=4 are thus interpreted as being at the upper critical dimension.
