Imagine a parallel universe where physicists are remunerated so handsomely that they can accumulate multitudinous assets. In this alternate universe, you naturally wish to share your good fortune, so ...

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 ...

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 ...

In 1994, a mathematician figured out how to make a quantum computer do something that no ordinary classical computer could. The work revealed that, in principle, a machine based on the rules of ...

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 ...
