Turing machines for computer science is an interesting topic from where you can expect a few questions in the GATE exam. It aims at testing the students' knowledge in deciding formal language and solving the mathematical functions. Tricky questions from this section can be solved easily when you are clear about the basics.

Turing machines MCQs are asked in a number of competitive exams. Thus, it is essential to practice the turing machines questions, mock tests, online quizzes to be thorough with this topic for GATE CS Exam.

Important Turing Machines topics for GATE CS

While preparing the Turing machines notes for CS, you will come across the following important topics:



Turing machine basics

You will learn about the definition and Turing machine transition function.

Behaviour of Turing machine

Here you will learn about deterministic and non-deterministic Turing machines.

Language recognition by Turing machine

CFL, CSL, Type-0 are the languages recognized by the Turing machine. You will also learn about recursive and recursively enumerable languages.

Tips to follow while preparing for Turing Machines topic for GATE:

  • Check the Turing machines syllabus for GATE, and accordingly start preparing on the subtopics. This will eliminate the chances of wasting time by going beyond what needs to be learned since there are a lot of things to be covered in depth. It is important to manage your time efficiently by creating a schedule for each of them.
  • When you start to study the turing machines topic, make Turing machines GATE notes. Refer to these while revising the topic before the exam. If you don't like preparing notes, try downloading Turing machines notes for GATE pdf from sites like BYJU'S Exam Prep, to save your time and learn quickly.
  • While solving the Turing machines MCQ questions, you may find some questions difficult to solve. It is better to get them clarified from the mentors immediately. Never wait till the end to clarify doubts.
  • Every chapter comes with some shortcuts and tricks that are quite necessary for solving the Turing machines online quiz. You can find them in the books, as well as in most online sites that provide Turing machines study material for GATE CS. Initially, you may find it difficult to use them, but it will become easier with practice.

Importance of Turing machine topic for GATE CS

  • The Turing machine has been the basis of the development of a lot of theoretical computer science. You can find a lot of basic results in the language of the Turing Machine because of its simplicity, which makes it easy to analyse.
  • The Turing machines GATE questions intend to gauge the efficiency of a candidate in undecidability, undecidable problems, post correspondence problem, and Modified PCP.
  • Correctly solving the problems from this topic shows the efficiency of a student in understanding the given scenario, and using the right concepts to reach the final answer in a limited time.
  • A higher score in the topic indicates the proficiency of a student to pursue higher studies in the related specialisation.

Recommended Books for learning Turing machines for GATE

Some of the Turing machines book that can be used for learning the concepts, and covering the Turing machines GATE syllabus are as follows:



Introduction to Automata Theory Languages and Computation

John E Hopcroft, Rajeev Motwani, Jeffrey D. Ullman

Theory of Computer Science-Automata Languages and Computation

K L P Mishra, N Chandrashekaran
