We show how to compute the entropy of two important classes of cellular automata namely, linear and positively expansive cellular automata. In particular, we prove a closed formula for the topological entropy of D-dimensional (D ≥ 1) linear cellular automata over the ring Zm (m ≥ 2) and we provide an algorithm for computing the topological entropy of positively expansive cellular automata.
