If, for example, the update scheme consists of applying the vertex functions synchronously one obtains the class of generalized cellular automata (CA). In this case, the global map F: K<sup>n</sup> → K<sup>n</sup> is given by | If, for example, the update scheme consists of applying the vertex functions synchronously one obtains the class of generalized cellular automata (CA).
