The DFA minimization is the process of reducing states in a deterministic finite automaton (DFA) and maintaining its language recognition abilities. That means, DFA minimization … Read more

Construct NFA without ∈ transitions NFA with ∈ Sol. Step 01: Find ∈-closure of (q1), (q2) and (q3). ∈-closure of (q1) = {q1, q2, q3}  … Read more

Indirect Method:  In this method, Step 01: Convert NFA with ∈ moves to NFA without ∈ moves. Step 02: Than NFA without ∈ moves is … Read more

NFA with ∈ moves is exactly same as NFA without ∈ moves.  But differece exist in the transition function δ. δ must include information about ∈ … Read more

Arden’s law is used in simplification of regular expression. It is states as, for p, q and r to be regular expressions, and if ∈ is … Read more

A regular expression is a sequence of patterns that defines a string. The language accepted by finite automata can be easily described by simple expressions … Read more

Example 1: Let Σ = {a, b}. Write regular expression to define language consisting of strings w such that, w contains only a’s or only b’s … Read more

A Mealy machine is a type of finite state automaton (FSA) that produces output on transitions between states. Unlike a Moore machine, which produces output … Read more

A Moore machine is a type of finite state automaton (FSA) that is characterized by its output function. Unlike a Mealy machine, which produces output … Read more

Example of NFA, Consider the NFA that accepts all string ending with 01. In this NFA,  M = {Q, Σ, δ, q0, F}  where,  Reference:
