Introduction to automata theory, languages, and computation / by John E. Hopcroft, .. The Formal Definition of Pushdown Automata A. 9 Jul This classic book on formal languages, automata theory, and computational complexity has been updated to present theoretical concepts. I have prepared a course in automata theory (finite automata, context-free grammars, decidability, and intractability), and it begins April 23, You can learn.
