Finite Automata and Grammar – Learn with Examples

Theory of computation create a strong foundation for a lot of abstract areas of computer science. Automata theory is the study of abstract mathematical model and it deals with definitions and properties of different types of “computation models”. Theory of computation teaches you about the elementary ways in which a computer can be made to think.

The computational models are:

Finite Automata: used in text processing, compilers, and hardware design.
Context-Free Grammars: used to define programming languages and in Artificial Intelligence.
Context-Sensitive Grammars: used for compiler designing and in Artificial intelligence.

In this course, learner will learn designing of finite automata which is has lot of applications.
Finite automata and grammar are also used in certain areas of Mathematics like Number Theory.
Regular expressions can be beautifully represented using non-deterministic Finite Automata.
An algorithm can be expressed in the form of a finite state machine and is really helpful visual representation of the same.

why to study Theory of computation??

Answer:

To better understand the development of formal mathematical models of computation that reflect the real-world of computer.
To achieve deep understanding about the mathematical properties of computer hardware and software.
To learn mathematical definitions of the computation and the algorithm.
To correct the limitations of computers and answer what kind of problems can be computed?
