In data compression, there are many different methods for compressing data. We have many different protocols because there is no one method that provides the absolute best compression for all files in a reasonable amount of time. Which of the following is the BEST term for the above example? a) An algorithm b) A heuristic c) A selection d) An iteration

A heuristic

Explanation:

Some time there are many methods to solve a particular problem, or learn something. These all methods are able to solve the problem. We cannot say that, which method is perfect or which one is optimal. These solutions are being used and sufficient to provide the solution. The technique that is used to solve problem in this way is called Heuristic.

For Example

There are many methods of teaching, few student understand some method and rest of the student better understand the other method of teaching. The students who think first method is perfect may think that other method is optimal and as well the students who think that second method is perfect, who may assume first solution as optimal.

The purpose of both of the teaching methods is to teach the students and both are sufficient to learn.
