Exercises on deterministc finite automata.
Non-determinism. Non-Deterministic Finite Automata (NDFA). Formal definition and representation by state diagrams. NDFAs have the same computational power than DFAs, that is, they recognize the same languages. (Sipser's book, Chapter 1.2)
 
Resolution of some exercises on Non-Deterministic Finite Automata (NDFA).
