WebThe problem of minimizing a given DFA (Deterministic Finite Automata) has a long history dating back to the beginnings of automata theory. Consider a deterministic finite automaton M as a tuple (Q, Σ, q 0 , F, δ) where Q, Σ, q 0 ∈ Q, F ⊆ Q and δ : Q × Σ → Q are a finite set of states, a finite input alphabet, the start state, the set of accepting (or final) states and … WebFewer DFA states is more eﬃcient For any regular languages: there is some minimal number of DFA states required Outcomes Understand algorithms for DFA state minimization: Hopcroft’s Algorithm Brzozowski’s Algorithm Dantam (MinesCSCI-561) L11: FiniteAutomataMinimization(PreLecture) Fall2024 2/22
