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.

On the application of formal language and automata theory to pattern recognition – ScienceDirect

The course first recapitulates basic knowledge concerning finite automata, context-free languages and Turing machines from the master studies; an emphasis is put on the rigorous approach and deeper understanding.

The main result presented here is that the nondeterministic 2-way and multi-head iterated pushdown automata characterize the deterministic iterated exponential time complexity classes.

This is proved by investigating both nondeterministic and alternating auxiliary iterated pushdown automata, for which similar characterization results are given. Subject has no prerequisities.

Abstract An iterated pushdown is a pushdown of pushdowns of … of pushdowns. In particular it is shown that alternation corresponds to one more iteration of pushdowns.
