Formal definition of DFA
What is the formal definition of DFA ?
Expert
A deterministic finite automaton is a 5-tuple
(Q, Σ, δ, q0, F)
- Q is a finite set called the states- Σ is a finite set called the alphabet- δ:Q x Σ→ Q is a function called the transition function - q0 is an element of Q called the start state- F is a subset of Q called the accept states
How can we characterize DFA languages ?
Give an algorithm that, given a grammar G = (V, Σ, R, S), decides whether the grammar G can derive the empty string.
Let α be a regular expression of length n. (a) Using procedures shown in class, if we convert α into a regular expression β such that L(β) = L(α). How long β might be? Give a reasonably tight upper bound.
