In automata theory, the transition function is a well-defined function that tells about the movement from one state to another upon receiving an input symbol. It is writen in set form as δ : Q X Σ - …

An extended transition function takes two arguments. The first argument is a state q and the second argument is a string w. It returns a state just like the transition function discussed in …

We present algorithms to convert a DFA to an equivalent one with a minimal number of states. First we define what DFA’s are, and then we explain how they are used to accept or reject …

In an extended finite automaton (EFA), the transition function is a total function mapping from Q × Q to R Σ, where Q is the set of states, Σ is the input alphabet, and R Σ represents the set of all …

Given an automaton \(M\), we define the extended transition function \(\hat{δ} : Q \times \Sigma^{\bf *} → Q\). Informally, \(\hat{δ}(q,x)\) tells us where \(M\) ends up after processing …

Difference between NFA and DFA Suppose that q is a state and a is an input symbol. In a DFA, we have (q;a) 2 Q, that is, (q;a) is a state. In a NFA, we have (q;a) 2 P(Q), that is, (q;a) is a set …

Let’s consider ε-transitions which can be taken without consuming any input symbol in finite automata. Let’s formally define ε-NFA, an extension of NFA with ε- transitions. = EClo(q2) ∪ …

Extended Transition Function • For a given dfa, the extended transition function * accepts as input a dfa state and an input string. The value of the function is the state of the automaton after the …

Using the extended transition function, evalDFA is easily defined: compute the state q = δ * (s, w) (where s is the start state, and w is the input string), and check if q is an element of the set F …
