Glider Collisions in Hybrid Cellular Automaton Rules

Elementary cellular automaton (ECA) rules 9 and 74, members of Chua’s Bernoulli shift rules and Wolfram’s class 2, can generate a host of gliders and complicated glider collisions by introducing the hybrid mechanism. These gliders and collisions are more plentiful than those generated by ECA rule 110. This paper presents a discussion of the symbolic dynamics of the gliders in hybrid cellular automaton (HCA) rules�9 and 74. Moreover, with regard to HCA rules that are composed of more than a couple of ECA rules, three other HCA rules endowed with gliders and glider collisions are discussed.
