Can 3SUM be solved in strongly sub-quadratic time, that is, in time O(n 2−ϵ) for some ϵ>0? Can the edit distance between two strings of length n be computed in strongly sub-quadratic time? (This is only possible if the strong exponential time hypothesis is false.) Can X + Y sorting be done in o(n 2 log n) time?
For some questions, there is no known way to find an answer quickly, but if provided with an answer, it can be verified quickly. The class of questions where an answer can be verified in polynomial time is "NP", standing for "nondeterministic polynomial time". [Note 1] An answer to the P versus NP question would determine whether problems that ...
This "yes-no" format is often equivalently stated as "accept-reject"; that is, an algorithm "accepts" an input string if the answer to the decision problem is "yes" and "rejects" if the answer is "no". While some problems cannot easily be expressed as decision problems, they nonetheless encompass a broad range of computational problems. [2]
The NFC wild-card game between the Los Angeles Rams and Minnesota Vikings is being moved to Arizona, the NFL announced Thursday. The game remains scheduled for Monday at 5 p.m. PT, but will now be ...
Kreskin (aka The Amazing Kreskin), the renowned mentalist who had his own TV programs in the 1970s, has died. He was 89. Kreskin’s family announced the news in a statement posted on social media ...
An estimated 11.7 million unauthorized migrants are living in the U.S. without legal immigration status, including about 4.6 million from Mexico, as of July 2023, according to the Center for ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
From January 2008 to December 2012, if you bought shares in companies when Monica C. Lozano joined the board, and sold them when she left, you would have a -17.7 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
