Does DFA have Epsilon transitions?

It's the same thing. DFA doesn't have epsilon transitions.If it had it, it could transit from current state to other state without any input i.e. with nothing , not even {} or phi. And as definition , we know that the input must be from the input set. Hope this cleared your doubt ... What if this transition was to a final state ?

What is the extended transition function of the -NFA?

Let ? denote the transition function and ? denoted the extended transition function of the ?-NFA whose transition table is given below: Explanation: Extended transition function describes what happens when we start in any state and follow any sequence of inputs.

What is an epsilon transition?

An epsilon transition allows two (or more) states to attempt to process the same input. When you enter a state that has epsilon transitions leaving it, you are also “entering” all the states that are targets of those epsilon transitions.

What is the difference between NFA and NFA with Epsilon?

NFA and NFA with epsilon both are almost the same; the only difference is their transition function. a * means there can be any number of ‘a’ in the expression, even 0 ( if the input symbol is null then also it is valid). b * means there can be any number of b’s in the expression, even 0 (if input symbol is null then also it is valid).
