**What is Computational Complexity?**

Computational Complexity is a computer science concept that focuses on the amount of computer resources needed to perform specific tasks. In computational complexity theory, researchers evaluate the types of resources required for a given type or class of task in order to divide different types of tasks into different levels of complexity.

Although computational complexity is in some ways comparable to analyzing algorithms, it is essentially a branch of mathematical theory in its own right. Some consider this approach a measure of how much work it would take to solve a particular problem or complete a particular task. Different types of analyst use Computational Complexity Research to find out which parts of a task are most difficult for a computer system, or to find out the most efficient way to complete a project.

Although some developers consider computational complexity to be irrelevant to their work, others have pointed out that successful changes to tasks or algorithms from a higher complexity class to a lower complexity class can make them work much better. Programmers and developers who use computational complexity theory for elements like nested loops.
