When Problem Is Said to Be Decidable Mcq?

Solution: Background: In computational complexity theory, a decision problem has only two possible outputs yes or no. A decision problem is said to be decidable if there exists an effective method or algorithm that returns a correct yes/no answer to that problem.

When we say a problem is decidable?

A problem is said to be Decidable if we can always construct a corresponding algorithm that can answer the problem correctly. We can intuitively understand Decidable problems by considering a simple example. Suppose we are asked to compute all the prime numbers in the range of 1000 to 2000.

Which of the following are decidable problem?

1) This is a variation of Turing Machine Halting problem and it is undecidable. 2)CFL are not closed under complement so it is undecidable. 3) Complement of Regular languages is also regular. ... 4) Recursvie language are closed under complement,so it is decidable.
