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 ...

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 ...

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 ...

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 ...
