An algorithm that can find an approximate result quickly when an exact result would be too expensive to calculate.
As an example, if you wanted to find the largest number among millions of numbers (and these numbers where somehow very expensive to find or operate on), you could sample a thousand of them, have a look at the statistical distribution of those thousand numbers, and say that the maximum among all the numbers is within such-and-such a range with such-and-such probability.
You could say that a public poll uses an approximation algorithm - instead of asking everyone in the country, you ask a small sample and extrapolate from the result using statistical methods.

What is the 2-approximation algorithm for solving the Traveling Salesman Problem?
The 2-approximation algorithm for the Traveling Salesman Problem is a method that provides a solution that is at most twice the optimal solution. This algorithm works by finding a minimum spanning tree of the given graph and then traversing the tree to form a tour that visits each vertex exactly once.

What is approximation error?
An approximation error is the discrepancy between an exact value and the approximation to it. This occurs when the measurement of something is not precise.
Is a heuristic an algorithm?
In practice, it may be. But they are still different things.A heuristic is a rough approximation that can help solving a problem.For example, in a path-finding algorithm, if your destination is northbound, you may try goring north first. This is the heuristic.It may not be correct (there may be a dead-end) but most of the time, it helps getting there faster.
When was Constructive Approximation created?
Constructive Approximation was created in 1985.
