Lance Fortnow on the current status and future outlook of solving the P-NP problem.

The biggest problem in computer science remains unsolved, but researchers are more confident than ever about what the answer should be. A new poll reveals opinions on the P versus NP problem, the ...

1. The P v. NP problem asks whether all problems whose solutions can be verified in some time can also be solved in a comparable length of time. What is this length of time called for the purpose of ...

In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms, any ...
