Briefly explain the classes P and NP problems with example
Understand the Problem
The question is asking for a brief explanation of P and NP problems in computational theory, along with examples of each. P problems are those that can be solved quickly (in polynomial time) by a deterministic algorithm, while NP problems are those for which a solution can be verified quickly, though finding that solution may not be efficient. An example of a P problem is sorting a list of numbers, while an example of an NP problem is the Traveling Salesman Problem.
Answer
P problems are quickly (polynomial time) solvable, like sorting a list. NP problems have quickly verifiable solutions, like the Travelling Salesman Problem.
The final answer is: P problems are solvable quickly (in polynomial time), while NP problems have solutions that can be verified quickly, but may not be quickly solvable. An example of a P problem is sorting a list, and an example of an NP problem is the Travelling Salesman Problem.
Answer for screen readers
The final answer is: P problems are solvable quickly (in polynomial time), while NP problems have solutions that can be verified quickly, but may not be quickly solvable. An example of a P problem is sorting a list, and an example of an NP problem is the Travelling Salesman Problem.
More Information
P and NP are classes in computational complexity theory. P consists of problems solvable in polynomial time, while NP problems' solutions can be quickly verified given the right information. The distinction is fundamental in computer science, with significant open questions, like whether P equals NP.
Tips
A common mistake is to confuse NP problems as those that are unsolvable; instead, they have solutions that are difficult to find but easy to verify.
