What are equivalent states in FSM?
Definition (state equivalence): Two states Si and Sj of a Moore FSM are equivalent if (.
1) Si and Sj produce identical outputs; and (2) for every combination of inputs, Si and Sj transition to equivalent states.
How do you convert a finite automata for a given regular expression?
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.
Finite automata are formal (or abstract) machines for recognizing patterns.
These machines are used extensively in compilers and text editors, which must recognize patterns in the input.
Regular expressions are a formal notation for generating patterns.

What is equivalent of finite automata?

DFAs are equivalent in computing power to nondeterministic finite automata (NFAs).
This is because, firstly any DFA is also an NFA, so an NFA can do what a DFA can do.

Equivalence of Regular Expressions and Finite Automata Regular expressions and finite automata have equivalent expressive power: For every regular expression R, there is a corresponding FA that accepts the set of strings generated by R.
