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 the more general case , a solution is outlined below.) The solution is expressed recursively. Let () denote the position of the survivor when there are initially n people (and =). The first time around the circle, all of the even-numbered people die. The second time around the circle, the new 2nd person dies, then the new 4th person, etc ...
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.
A decision problem has only two possible outputs, yes or no (or alternately 1 or 0) on any input. Decision problems are one of the central objects of study in computational complexity theory. A decision problem is a type of computational problem where the answer is either yes or no (alternatively, 1 or 0).

Los Angeles Chargers kicker Cameron Dicker just did something no NFL player has done since 1976. What is a fair-catch kick? ... (3-9 and 11-4-3). This includes the 15-yard penalty enforced from ...
Also available in blue and ivory shades, this ridiculously plush throw measures 50" x 70" making it just big enough for two people to curl up under. Hello, holiday movie marathon! $32 at Nordstrom
In computational complexity theory, a complexity class is a set of computational problems "of related resource-based complexity". [1] The two most commonly analyzed resources are time and memory. In general, a complexity class is defined in terms of a type of computational problem, a model of computation, and a bounded resource like time or memory.
