What to learn in automata tutorial?
In this Automata Tutorial, you’ll learn all the basic to advanced topics like Regular languages and finite automata, Context free Grammar and Context-free language, turning machines, etc. DFA in LEX code which accepts even number of zeros and even number of ones.
What is automata theory?
Automata Theory is a branch of computer science that deals with designing abstract selfpropelled computing devices that follow a predetermined sequence of operations automatically. An automaton with a finite number of states is called a Finite Automaton.
What is a finite automata tutorial?
This is a brief and concise tutorial that introduces the fundamental concepts of Finite Automata, Regular Languages, and Pushdown Automata before moving onto Turing machines and Decidability. This tutorial has been prepared for students pursuing a degree in any information technology or computer science related field.

Deterministic Finite Automata

A formalism for defining languages, consisting of: A finite set of states (Q, typically). An input alphabet (Σ, typically). A transition function (δ, typically). A start state (q 0, in Q, typically). A set of final states (F ⊆ Q, typically). “Final” and “accepting” are synonyms. infolab.stanford.edu

The Transition Function

Takes two arguments: a state and an input symbol. δ(q, a) = the state that the DFA goes to when it is in state q and input a is received. infolab.stanford.edu

Graph Representation of DFA’s

Nodes = states. Arcs represent transition function.  Arc from state p to state q labeled by all those input symbols that have transitions from p to q. Arrow labeled “Start” to the start state. Final states indicated by double circles. infolab.stanford.edu

Delta-hat

In book, the extended δ has a “hat” to distinguish it from δ itself. Not needed, because both agree when the string is a single symbol. δ(q, ˄ a) = δ(δ(q, ε), ˄ a) = δ(q, a) Extended deltas infolab.stanford.edu

Regular Languages

A language L is regular if it is the language accepted by some DFA.  Note: the DFA must accept only the strings in L, no others. Some languages are not regular.  Intuitively, regular languages “cannot count” to arbitrarily high integers. infolab.stanford.edu

But Many Languages are Regular

Regular Languages can be described in many ways, e.g., regular expressions. They appear in many contexts and have many useful properties. Example: the strings that represent floating point numbers in your favorite language is a regular language. infolab.stanford.edu
