Equivalence of automata states that ____________(a) two automata accept the same set of input strings(b) two automata have same set of states(c) two automata does not contain initial input symbols(d) two automata share equal transition functionThis question was addressed to me in an interview for internship.My enquiry is from Modeling Computations in division Boolean Algebra and Modeling Computations of Discrete Mathematics

Answer»

The correct ANSWER is (a) two automata accept the same set of INPUT strings

Easy explanation: The formal definition is if two automata J and K are EQUIVALENT then if there is a path from the start state of J to a final state of J and there is a path from the start state of k to a final state of K as WELL as if there is a path from the start state of K to a final state of K, where there is a path from the start state of J to a final state of J. Two automata J and K are said to be equivalent if both automata accept exactly the same set of input strings.
