Testing the equivalence of regular expressions
This problem is normally solved by transforming each regular expression to equivalent nondeterministic finite automata; convert those automata into equivalent |
An equivalence relation on the set of automata, which arises in the context of studying some individual internal properties of automata.
Such a property is usually the behaviour of automata (cf.
Automaton, behaviour of an), since two automata are considered equivalent if their behaviour is identical.
How do you convert regular expressions to automata?
Steps To Convert Regular Expressions To Finite Automata
Step 1: Make a transition diagram for a given regular expression, using NFA with ε moves.
Step 2: Then, Convert this NFA with ε to NFA without ε.
Step 3: Finally, Convert the obtained NFA to equivalent DFA.
What is equivalence between two automata?
Explanation: Two finite state machines are said to be equivalent if they recognize the same set of tokens.
Consider two automata M1 and M2, these are called equivalent for an input sequence if they produce the same output result.
What is equivalence between two regular expressions?
We say that two regular expressions R and S are equivalent if they describe the same language.
In other words, if L(R) = L(S) for two regular expressions R and S then R = S.
