Travelling Salesman (2012 Film)
''Travelling Salesman'' is a 2012 intellectual thriller film about four mathematicians who solve the P versus NP problem, one of the most challenging mathematical problems in history. The title refers to the travelling salesman problem, an optimization problem that acts like a key to solving other difficult mathematical problems. It has been proven that a quick travelling salesman algorithm, if one exists, could be converted into quick algorithms for many other difficult tasks, such as factoring large numbers. Since many cryptographic schemes rely on the difficulty of factoring integers to protect their data, a quick solution would enable access to encrypted private data like personal correspondence, bank accounts and, possibly, government secrets. The story was written and directed by Timothy Lanzone and premiered at the International House in Philadelphia on June 16, 2012. After screenings in eight countries, spanning four continents, including screenings at the University o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thriller (genre)
Thriller is a genre of fiction, having numerous, often overlapping subgenres. Thrillers are characterized and defined by the mood (psychology), moods they elicit, giving viewers heightened feelings of suspense, Psychomotor agitation, excitement, Surprise (emotion), surprise, anticipation (emotion), anticipation and anxiety. Successful examples of thrillers are Alfred Hitchcock filmography, the films of Alfred Hitchcock. Thrillers generally keep the audience on the "edge of their seats" as the plot builds towards a climax (narrative), climax. The cover-up of important information is a common element. Literary devices such as red herrings, plot twists, unreliable narrators, and cliffhangers are used extensively. A thriller is often a villain-driven plot, whereby they present obstacles that the protagonist must overcome. The most common genres that overlap with the thriller genre include crime fiction, crime, horror fiction, horror and detective fiction. Characteristics Writer Vla ...

Films About Mathematics
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitiz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P (complexity)
In computational complexity theory, P, also known as PTIME or DTIME(''n''O(1)), is a fundamental complexity class. It contains all decision problems that can be solved by a deterministic Turing machine using a polynomial amount of computation time, or polynomial time. Cobham's thesis holds that P is the class of computational problems that are "efficiently solvable" or " tractable". This is inexact: in practice, some problems not known to be in P have practical solutions, and some that are in P do not, but this is a useful rule of thumb. Definition A language ''L'' is in P if and only if there exists a deterministic Turing machine ''M'', such that * ''M'' runs for polynomial time on all inputs * For all ''x'' in ''L'', ''M'' outputs 1 * For all ''x'' not in ''L'', ''M'' outputs 0 P can also be viewed as a uniform family of boolean circuits. A language ''L'' is in P if and only if there exists a polynomial-time uniform family of boolean circuits \, such that * For all n \in \m ...

NP-hardness
In computational complexity theory, NP-hardness ( non-deterministic polynomial-time hardness) is the defining property of a class of problems that are informally "at least as hard as the hardest problems in NP". A simple example of an NP-hard problem is the subset sum problem. A more precise specification is: a problem ''H'' is NP-hard when every problem ''L'' in NP can be reduced in polynomial time to ''H''; that is, assuming a solution for ''H'' takes 1 unit time, ''H''s solution can be used to solve ''L'' in polynomial time. As a consequence, finding a polynomial time algorithm to solve any NP-hard problem would give polynomial time algorithms for all the problems in NP. As it is suspected that P≠NP, it is unlikely that such an algorithm exists. It is suspected that there are no polynomial-time algorithms for NP-hard problems, but that has not been proven. Moreover, the class P, in which all problems can be solved in polynomial time, is contained in the NP class. Defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computational Complexity Theory
In theoretical computer science and mathematics, computational complexity theory focuses on classifying computational problems according to their resource usage, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying their computational complexity, i.e., the amount of resources needed to solve them, such as time and storage. Other measures of complexity are also used, such as the amount of communication (used in communication complexity), the number of gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing). One of the roles of computationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
