Metagame Analysis
Metagame analysis involves framing a problem situation as a strategic game in which participants try to realise their objectives by means of the options available to them. The subsequent meta-analysis of this game gives insight in possible strategies and their outcome. Origin Metagame theory was developed by Nigel Howard in the 1960s as a reconstruction of mathematical game theory on a non-quantitative basis, hoping that it would thereby make more practical and intuitive sense . Metagame analysis reflects on a problem in terms of decision issues, and stakeholders who may exert different options to gain control over these issues. The analysis reveals what likely scenarios exist, and who has the power to control the course of events. The practical application of metagame theory is based on the analysis of options method, first applied to study problems like the strategic arms race and nuclear proliferation. Method Metagame analysis proceeds in three phases: analysis of options, scena ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Game
A game is a structured form of play (activity), play, usually undertaken for enjoyment, entertainment or fun, and sometimes used as an educational tool. Many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games). Games are sometimes played purely for enjoyment, sometimes for achievement or reward as well. They can be played alone, in teams, or online; by amateurs or by professionals. The players may have an audience of non-players, such as when people are entertained by watching a World Chess Championship, chess championship. On the other hand, players in a game may constitute their own audience as they take their turn to play. Often, part of the entertainment for children playing a game is deciding who is part of their audience and who is a player. A toy and a game are not the same. Toys generally allow for unrestr ...

Game Theory
Game theory is the study of mathematical models of strategic interactions among rational agents. Myerson, Roger B. (1991). ''Game Theory: Analysis of Conflict,'' Harvard University Press, p.&nbs1 Chapter-preview links, ppvii–xi It has applications in all fields of social science, as well as in logic, systems science and computer science. Originally, it addressed two-person zero-sum games, in which each participant's gains or losses are exactly balanced by those of other participants. In the 21st century, game theory applies to a wide range of behavioral relations; it is now an umbrella term for the science of logical decision making in humans, animals, as well as computers. Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum game and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathema ...

Computational Problem
In theoretical computer science, a computational problem is a problem that may be solved by an algorithm. For example, the problem of factoring :"Given a positive integer ''n'', find a nontrivial prime factor of ''n''." is a computational problem. A computational problem can be viewed as a set of ''instances'' or ''cases'' together with a, possibly empty, set of ''solutions'' for every instance/case. For example, in the factoring problem, the instances are the integers ''n'', and solutions are prime numbers ''p'' that are the nontrivial prime factors of ''n''. Computational problems are one of the main objects of study in theoretical computer science. The field of computational complexity theory attempts to determine the amount of resources ( computational complexity) solving a given problem will require and explain why some problems are intractable or undecidable. Computational problems belong to complexity classes that define broadly the resources (e.g. time, space/memory, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scenario
In the performing arts, a scenario (, ; ; ) is a synoptical collage of an event or series of actions and events. In the ''commedia dell'arte'', it was an outline of entrances, exits, and action describing the plot of a play, and was literally pinned to the back of the scenery. It is also known as ''canovaccio'' or "that which is pinned to the canvas" of which the scenery was constructed. Surviving scenarios from the Renaissance contain little other than character names, brief descriptions of action, and references to specific lazzi with no further explanation. It is believed that a scenario formed the basis for a fully improvisational performance, though it is also likely that they were simple reminders of the plot for those members of the cast who were literate. Modern commedia troupes most often make use of a script with varying degrees of additional improvisation. In the creation of an opera or ballet, a scenario is often developed initially to indicate how the original sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arms Race
An arms race occurs when two or more groups compete in military superiority. It consists of a competition between two or more states to have superior armed forces; a competition concerning production of weapons, the growth of a military, and the aim of superior military technology, the term is also used to describe any long-term escalating competitive situation where each competitor or competitive group focuses on out-doing others. Unlike a sporting race, which constitutes a specific event with winning interpretable as the outcome of a singular project, arms races constitute spiralling systems of on-going and potentially open-ended behavior. The existing scholarly literature is divided as to whether arms races correlate with war. International-relations scholars explain arms races in terms of the security dilemma, rationalist spiral models, states with revisionist aims, and deterrence models. Examples Pre-First World War naval arms race From 1897 to 1914, a nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as " Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states. Four countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to the NPT in 1985, then withdrew in 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metagame
Metagame, Hypergame, or game about the game, is an approach to a game that transcends or operates outside of the prescribed rules of the game, uses external factors to affect the game, or goes beyond the supposed limits or environment set by the game. ''Metagaming'' might also refer to a game which functions to create or modify the rules of a sub-game. Thus, we might play a metagame selecting which rules will apply during the play of the game itself. Etymology The origin of the idea of metagames originally came from the game theory field, with ideas first published in the groundbreaking '' Theory of Games and Economic Behavior'' by John von Neumann and Oskar Morgenstern in 1944, though the term itself was not originally used in that work. The word can be found being used in the context of playing zero-sum games in a publication by the Mental Health Research Institute in 1956. It is claimed that the first known use of the term was in Nigel Howard's book ''Paradoxes of Rational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combinatorial Explosion
In mathematics, a combinatorial explosion is the rapid growth of the complexity of a problem due to how the combinatorics of the problem is affected by the input, constraints, and bounds of the problem. Combinatorial explosion is sometimes used to justify the intractability of certain problems.http://intelligence.worldofcomputing/combinatorial-explosion Combinatorial Explosion. Examples of such problems include certain mathematical functions, the analysis of some puzzles and games, and some pathological examples which can be modelled as the Acker ...

Status Quo
is a Latin phrase meaning the existing state of affairs, particularly with regard to social, political, religious or military issues. In the sociological sense, the ''status quo'' refers to the current state of social structure and/or values. With regard to policy debate, it means how conditions are, contrasted with a possible change. For example: "The countries are now trying to maintain the ''status quo'' with regard to their nuclear arsenals." To maintain the ''status quo'' is to keep things the way they presently are. The related phrase ''status quo ante'', literally "the status before", refers to the state of affairs that existed previously. Political usage Via social movements the status quo might be overhauled. These seek to alleviate or prevent a particular issue and often to shape social feeling and cultural expression of a society or nation. The status quo is at least in part rejected by their protagonists – progressives – leading the movement. Advocat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compromise
To compromise is to make a deal between different parties where each party gives up part of their demand. In arguments, compromise is a concept of finding agreement through communication, through a mutual acceptance of terms—often involving variations from an original goal or desires. Defining and finding the best possible compromise is an important problem in fields like game theory and the voting system. Research has indicated that suboptimal compromises are often the result of negotiators failing to realize when they have interests that are completely compatible with those of the other party and settle for suboptimal agreements. Mutually better outcomes can often be found by careful investigation of both parties' interests, especially if done early in negotiations. The compromise solution of a multicriteria decision making or multi-criteria decision analysis problem that is the closest to the ideal could be determined by the VIKOR method, which provides a maximum utility of ...

Confrontation Analysis
Confrontation analysis (also known as dilemma analysis) is an operational analysis technique used to structure, understand and think through multi-party interactions such as negotiations. It is the underpinning mathematical basis of drama theory. It is derived from game theory but considers that instead of resolving the game, the players often redefine the game when interacting. Emotions triggered from the potential interaction play a large part in this redefinition. So whereas game theory looks on an interaction as a single decision matrix and resolves that, confrontation analysis looks on the interaction as a sequence of linked interactions, where the decision matrix changes under the influence of precisely defined emotional ''dilemmas''.Sedefinition of Dilemma/ref> Derivation and use Confrontation analysis was devised by Professor Nigel Howard (professor), Nigel Howard in the early 1990s drawing from his work on game theory and metagame analysis. It has been turned to defence, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
