41. Cellular automata have been proposed for public key cryptography. 42. ATNs used an equivalent set of finite state automata that were called recursively. 43. Automata theory is closely related to formal language theory.44. Autom is in the process of being commercialized ( see Intuitive Automata ). 45. DFAs are equivalent in computing power to nondeterministic finite automata ( NFAs ). 46. This property is useful in the applications of cellular automata to physical simulation. 47. Packard is known for his contributions to both chaos theory and cellular automata . 48. Two fundamentally spatial simulation methods are cellular automata and agent-based modeling. 49. We can represent grammars as finite state automata or context-free grammars. 50. Ginsburg's early work concentrated on automata theory.
