Finite Automata
In this chapter, we introduce the definition of Finite Automaton (FA) and also some real-time problems that can be solved using FA. Representation of FA is done using 5-tuple form, transition table and transition diagram. Definitions of non-deterministic and deterministic FAs are explained with examples and, further, how these automata act as language acceptor is elaborated. Equivalence of NFAs-with-ɛ to NFAs-without-ɛ, and equivalence of NFAs to DFAs are explained. Minimizing the given automaton using Myhill Nerode and π construction method, and testing the equivalence of two FAs are discussed. Moore and Mealy machines, which represent Finite Automaton with output, are explained with examples.
