21. Church introduced RRA in 1955 as an axiomatic formalization of finite automata . 22. Von Neumann also worked on what he called the cellular automata environment. 23. Continuous Valued Cellular Automata or Continuous Automata are CA with continuous resolution. 24. Continuous Valued Cellular Automata or Continuous Automata are CA with continuous resolution. 25. The global state approach was continued in automata theory for nondeterministic versions. 26. There is a connection between quantum-dot cells and cellular automata . 27. As an example, semiautomata underpin the concept of quantum finite automata . 28. For such a discrete motion, the cellular-automata type rule. 29. Automata were popular in the imaginary worlds of medieval literature.30. His work on automata theory investigates determinization and complementation of Rabin automata.
