Complexity classes

The problems that computer algorithms try to solve fall within a range of difficulty by which their solutions are arrived at. In this section, we will discuss the complexity classes N, NP, NP-complete, and NP-hard problems.

P versus NP

The advent of computers has sped up the rate at which certain tasks are performed. In general, computers are good at perfecting the art of calculation and all problems that can be reduced to a set of mathematical computations. However, this assertion is not entirely true. There are some nature or classes of problems that just take an enormous amount of time for the computer to make a sound guess, let alone find the right solution.

In computer science, the class of problems that computers can solve within polynomial time using a step-wise process of logical steps is called P-type problems, where P stands for polynomial. These are relatively easy to solve.

Then there is another class of problems that is considered very hard to solve. The word...
