NP
NP stands for Non-deterministic Polynomial time. It is a complexity class in computer science that contains decision problems which can be solved by a non-deterministic Turing machine in polynomial time. In other words, given a solution to the problem, it can be verified in polynomial time. NP is an important class in complexity theory and is closely related to the famous P vs NP problem, which asks whether every problem in NP can be solved in polynomial time by a deterministic Turing machine. Many important problems in computer science and artificial intelligence, such as the traveling salesman problem and the knapsack problem, are known to be in NP. While it is not known whether P equals NP, many researchers believe that the two classes are distinct, which would imply that there are problems that are inherently difficult to solve.
