Introduction to Undecidability In the theory of computation, we often come across such problems that are answered either ‘yes’ or ‘no’. The…

Conversion from NFA to DFA In this section, we will discuss the method of converting NFA to its equivalent DFA. In NFA,…

DFA (Deterministic finite automata) DFA refers to deterministic finite automata. Deterministic refers to the uniqueness of the computation. The finite automata are…

Minimization of DFA Minimization of DFA means reducing the number of states from given FA. Thus, we get the FSM(finite state machine)…

Conversion from NFA with ε to DFA Non-deterministic finite automata(NFA) is a finite automata where for some cases when a specific input…

Examples of DFA Example 1: Design a FA with ∑ = {0, 1} accepts those string which starts with 1 and ends…

Pushdown Automata(PDA) Pushdown automata is a way to implement a CFG in the same way we design DFA for a regular grammar.…

Conversion of RE to FA To convert the RE to FA, we are going to use a method called the subset method.…
