What is the tractable & intractable problem?

Tractable Problem: a problem that is solvable by a polynomial-time algorithm. The upper bound is polynomial. Intractable Problem: a problem that cannot be solved by a polynomial-time al- gorithm. The lower bound is exponential.

What is tractable and intractable problems in DAA?

Tractable: a problem that can be solved in polynomial time. intractable: a problem that can NOT be solved in polynomial time.

What are tractable problems?

Tractable problem, in computational complexity theory, a problem that can be solved in polynomial time. Tractable, ease of obtaining a mathematical solution such as a closed-form expression.

What is a tractable problem business?

The tractability of a problem refers to how difficult problem is in terms of the amount of time it takes for the problem to be solved. This is related to the time complexity of the problem.

Are NP problems tractable?

NP-complete problem So-called easy, or tractable, problems can be solved by computer algorithms that run in polynomial time; i.e., for a problem of size n, the time or number of steps needed to find the solution is a polynomial function of n.

What does tractable mean in math?

Sufficiently operationalizable or useful
(mathematics) Sufficiently operationalizable or useful to allow a mathematical calculation to proceed toward a solution. quotations ▼ (computer science, of a decision problem) Algorithmically solvable fast enough to be practically relevant, typically in polynomial time.

What is undecidable problems explain with example?

In computability theory, an undecidable problem is a type of computational problem that requires a yes/no answer, but where there cannot possibly be any computer program that always gives the correct answer; that is, any possible program would sometimes give the wrong answer or run forever without giving any answer.

What are undecidable problems in theory of computation?

The problems for which we can’t construct an algorithm that can answer the problem correctly in the infinite time are termed as Undecidable Problems in the theory of computation (TOC). A problem is undecidable if there is no Turing machine that will always halt an infinite amount of time to answer as ‘yes’ or ‘no’.
