ε 0,1, 9 0,1, 9 Nondeterministic Finite Automata with ε transitions (ε-NFA) DFA / NFA / ε-NFA Equivalence DFAs and NFAs and ε-NFA are all equivalent

Formally, a Nondeterministic Finite Automata (NFA) is a quintuple A = (Q, Σ, δ, q 0 , F) 1 There is an NFA N with n+1 states that has no equivalent DFA with fewer than 2n states Equivalence of DFA and ε-NFA - Theorem Theorem: A

Proof Idea We will build the NFA NR for R, inductively, based on the number of operators in R, #(R) • Base Case: #(R) = 0 means that R is ∅,ϵ, or a (from some a
