The question is whether or not, for all problems for which an algorithm can verify a given solution quickly (that is, in polynomial time), an algorithm can also find that solution quickly. Since the former describes the class of problems termed NP, while the latter describes P, the question is equivalent to asking whether all problems in NP are ...
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.
Hilbert’s sixth problem was a proposal to expand the axiomatic method outside the existing mathematical disciplines, to physics and beyond. This expansion requires development of semantics of physics with formal analysis of the notion of physical reality that should be done. [9]
Smale's problems is a list of eighteen unsolved problems in mathematics proposed by Steve Smale in 1998 [1] and republished in 1999. [2] Smale composed this list in reply to a request from Vladimir Arnold, then vice-president of the International Mathematical Union, who asked several mathematicians to propose a list of problems for the 21st century.
An angry, drunken grandma has been busted in Tennessee for allegedly stabbing her daughter and grandson with a kitchen knife during a Thanksgiving Day argument.
DETROIT (Reuters) -U.S. automakers Ford Motor and General Motors will donate $1 million each, along with vehicles, to U.S. President-elect Donald Trump's January inauguration, company ...
CHICAGO, Illinois (Reuters) -Federal Reserve officials appear more likely to cut rates this month after data showed the U.S. labor market remained strong but continued to cool in November, with a ...
The Combat Estimate, also known as the Seven Questions is a sequence of questions used by military commanders, usually in contact with the enemy, to plan their response, such as a platoon attack. [ 1 ] [ 2 ] It provides a means for formulating a plan that meets the exigencies of battle, even in very difficult circumstances.
