## What is computational intractability?

From Computer Science Wiki. Advanced programming. **An intractable problem is a problem in which the only exact solution is one that takes too many resources (time, memory, etc.)**. In other words, a problem in which no efficient solution (other than the worst-case complexity) exists.

## What are tractable and Nontractable problems?

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 causes a problem to be intractable?

We refer to any algorithm whose running time is bounded by a polynomial in the input size (e.g., N log N or N^2) as a polynomial-time algorithm. We say that a problem is intractable **if there is no polynomial-time algorithm for the problem**.

## What problems are considered tractable?

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. Algorithms for solving hard, or intractable, problems, on…

## What do you mean by computational complexity?

computational complexity, **a measure of the amount of computing resources (time and space) that a particular algorithm consumes when it runs**.

## Why is computational complexity important?

Computational complexity is very important in analysis of algorithms. **As problems become more complex and increase in size, it is important to be able to select algorithms for efficiency and solvability**. The ability to classify algorithms based on their complexity is very useful.

## What does tractable mean?

Definition of tractable

1 : **capable of being easily led, taught, or controlled** : docile a tractable horse. 2 : easily handled, managed, or wrought : malleable.

## What are P and NP problems?

The P versus NP problem is **a major unsolved problem in computer science**. It asks whether every problem whose solution can be quickly verified can also be solved quickly.

## 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.

## What is a tractable model?

1. A ‘tractable’ model is **one that you can solve**, which means there are several types of tractability : analytical tractability (finding a solution to a theoretical model), empirical tractability (being able to estimate/calibrate your model) and computational tractability (finding numerical solutions).

## What things are tractable?
