## Games Theory: Meaning, Origin, Types and Application

The theory of games was originally devised for its application in economics. Stone-paper-scissors is also a fair game and both players have optimal strategies that employ each choice one third of the time. Studying such links might be more difficult in other areas - such as the kinetic theory of gases or topology. Indeed, one of the things that makes this analysis of game theory hard for me is the perpetual inclination to think in terms of a game theory formulation. That is the branch of game theory I will discuss here. I summarize it here, with my comments in parentheses. In some areas of mathematics alternative theories exist - for example, catastrophe theory in biology - and can throw great light on the origin of the selective usefulness of different mathematical formalisms.

## What is game theory? definition and meaning

In this case, if B supports, opposes, or evades, the maximum A will get is 80, 30, and 80, respectively. Carse, a book about game theory written by a religious scholar, is admittedly very weird. In particular Morgenstern's strong bent towards militaristic thinking in simplistic terms seems consonant with biases in the structure of game theory. With no opponents, the player only needs to list available options and then choose the optimal outcome. Finding each dealership that has the car you are looking for in a given radius is the first step. The saddle point in a game is the equilibrium point.

## What is the 'Game Theory'? Why is it important in Economics?

Fantasy football is an N-player game, meaning there are more than two players participating. Another important concept, , also stemmed from the original ideas presented in game theory and the Nash equilibrium. In games players can communicate and, most important, make binding agreements; in noncooperative games players may communicate, but they cannot make binding agreements, such as an enforceable contract. Also known as a Nash equilibrium, the minimax solution is the strategy with the maximum assured minimum gain for a player. The outcomes and strategies are interdependent which means that what strategy one participant will adopt will depend upon the strategy of another man or participant and in this way games proceed from one strategic point to another strategic point. It is surprising that its sponsors have not thought it fit to highlight their aspect of the theory. Variable-Sum Games : There is another type of games theory narrated by Karl Deutsch in his The Analysis of International Relations.

## How To Use Game Theory To Your Benefit

The legend of John Von Neumann gives a good insight on who John Von Neumann was and his theory. After the Second World War 1939-45 the world was divided into two campsâ€”one was led by the United States and the other by the erstwhile Soviet Union. In game theory, self-interest is routed through the mechanism of economic competition to bring the system to the saddle point. Symmetric and Asymmetric Games : In symmetric games, strategies adopted by all players are same. The police do not actually have enough evidence to convict the two, so they try to make at least one of them confess. The limitations of such an approach are numerous: it ignores collusion between police and criminals; it ignores the possibility of value change for example, decrease in materialism or structural change equitable distribution of wealth in society leading to decreased criminal activity; it defines criminal activity as what is discouraged now by police robbery, murder and ignores structural violence in society poverty, war, racism , not to mention crime by other classes or occupations for example, white collar crime ;it assumes the continuance of present laws for example against abortion, alcoholism, or loitering which may be unnecessary or unjust; and so on.

Importance of Game Theory : Game theory possesses the following merits: 1. The profits of the participants remain the same, whereas in a non-constant-sum game, profits of each player differ and they may co-operate with each other to increase their profits. But he was perhaps not aware that the capitalist economy or liberal political system is capable of controlling the crisis. There is also a place of intelligence. Yet this example is typical of the use of game theory ideas for 'studying' international relations. In this scenario, two people are arrested for stealing a car.

However, the theory of games has not been developed for games with more than four players. In the game certain amount of uncertainty is involved. In other words, the theory of games is an important device to show the way how to come out of the crisis and depression which engulfed the economy. Even more so than observations, mathematical or logical formulations used in science may be closely tied to special ways of interpreting the world, and so selectively lend themselves to particular uses in society. But from the point of view of game theory's value-laden concepts and selective usefulness, these 'misuses' are not due so much to fault of users as to the bias in the theory itself: the theory lends itself to 'misuse'. Jim, the new boy in town, is a teenager on an unrelenting quest to find his place in the world.

## The Selective Usefulness of Game Theory

In the next Section a simple introduction to the concepts of game theory will be given. Ostrom, 'A Review of Conflict Resolution Models in Water Resources Management', in A. The safecracker and the guard give away nothing if they announce the probabilities with which they will randomly choose their respective strategies. Game theory turned attention away from steady-state equilibrium toward the market process. In the game, the prisoners have only two possible actions: confess to the bank robbery, or deny having participated in the bank robbery.

Many-person non-zero-sum games where it pays to cooperate are used in of economic. The example of simultaneous linear equations is almost too trivial to count as game theory mathematics. The value of the game, denoted by v, is the value that a player, say Player 1, is guaranteed to at least win if he sticks to the designated optimal mix of strategies no matter what mix of strategies Player 2 uses. In this case, the best option would be that organization A enters the market and organization B cooperates. In normal form games, the matrix demonstrates the strategies adopted by the different players of the game and their possible outcomes. Although game theory is relevant to parlor games such as poker or bridge, most research in game theory focuses on how groups of people interact. This result was proven by John Nash and was pictured in the movie, A Beautiful Mind.

Noncooperative game theory deals with how rational economic agents deal with each other to achieve their own goals. In the melee some prisoners escape and this is their gain while others fail to do this and this is their loss. Further, game theory has been used to explain the market equilibrium when more than two firms are involved. The answer depends on one's perspective; in the perspective favoured here it is useful to associate values with the mathematical formalism. Table 2When a saddlepoint does not exist for a payoff matrix, a probabilistic strategy is optimal. If so we cannot be any more suspicious about its narrowness or other limitations.

The question of morality does not apply, it just does not arise. It is always so in chess or poker games, military battles and economic markets. The consequent series of 'accidents' might be blamed on the carelessness of users; but most people would find it more reasonable to blame the designer and promoter. Rationality is still another assumption. Game theory is best exemplified by a classic hypothetical situation called the Prisoners' Dilemma.
