The Scientific Field Of Game Theory

Games can be very hard. States can be only observes to a certain extend. Multiple agents choose Actions, stochastic pays off and state transition depends on state and other

Good post and I choose game theory as well. Game theory deals with any situation in which the reward of any one player (called the payoff) depends on not only his or her own actions but also on those of other players in the game. Game theory provides a technique that is suited to investigate such interactions, but as applied in the research literature it is a far more mathematical treatment than might be suggested by our attempt to explain its nature in a simple way.

Game theory cannot always predict reliable outcomes for real-life situations as it is more an

Nash equilibrium can be described as the end of the game sequence. Player gains a posteriori experience during the sequences of the game which in turn help them to form the belief and gain knowledge that lead to the end point, the Nash equilibrium, hence there is no further knowledge that can be gained. In the usual finite set of games the marking of the end point, Nash equilibrium, will allow us to make better or optimal decision. If our decision making process doesn’t satisfy the Nash equilibrium, we must always be able to improve our decision and choice that we made till we hit that equilibrium.

According to Shmaya (2006) suggest that player one should arrive with an overview of the implantations payoff to determine the game structure, Player one opposition is to determine the actions of player two. Also, recognizing that player one does not have the required information, whereas, one player have an advantage because the level of information is distribute evenly between the two players. Therefore, giving player two the advantage of achieving the necessary systematic outcome he would gain wealth that is equivalent to player one loss, and this consider a stochastic signals (Shmaya, 2006, p., 156-157).

Picture if you will a group of people making decisions. The decisions that are made do not have to be significant at all. They have to be just significant to the situation at hand. This concept is considered to mathematicians as Game Theory. Game Theory is broken down into tree different types of games. As stated by Thomas S. Ferguson of UCLA “There are three main mathematical models or forms used in the study of games, the extensive form, the strategic form and the coalitional form”. Some games that are the most popular to being discussed in Game Theory are chess, checkers, and tic-tac-toe (Ferguson). There are also different terms that are used in this theory as well. Some of the major terms are The Nash Equilibrium,

In an ultimatum game, if the other player accepts, the money is split according to the proposal and if the other player rejects, neither player receives anything. As suggested by game theory, the only sub-game perfect Nash equilibrium of the game is the strategy pair in which player one offers zero and player 2 accepts all offers. Rational responders should accept even the smallest positive offer, since the alternative is getting nothing. In a large number of human studies,

For example, using a game-theory to analyze the cartel stability and the incentive to collude with other firm also decrease. In the way about the role of

In this type of games the players have little information about their opponents’ payoff functions but they know the actions of all other players that were in the past. An example for those games is the Intrusion detection game, which is a 2-player zero-sum stochastic (Markov)

Decision concerning electrical transmission network expansion has become harder in the last two decades. As a matter of fact, the power sector has been decentralized and the electricity market is now a competitive market. Thus a transmission expansion plan cannot follow the traditional planning criteria anymore. As a result, new techniques are developed in order to solve the transmission expansion problem TEP.

The “Game” doesn’t always equate to the procedure that results in winning or loosing (which can be the case many a times). Here the connotation is merely utilized to provide a sense of structure involving strategies and plans to the whole process. As seen in a general Game, there are players and payoffs. Players have their strategies for particular situations, which may or may not depend on the other players’ moves. One interesting nature of game theory is seen when deciding moves using predefined strategies; our moves can be independent of those of the opponent’s, however, results occurring due to the combination moves are totally interdependent. This can be confusing but with understanding this underlining concept of game theory comes into light easily. This phenomenon is known as Strategic Interdependency. Simply described as: What I do affect your outcome, what you do affects my outcome.

Table 1 illustrates a game, which is represented in normal form, with the loss to a defender choosing from two defence options, to either defend target A or B on whether the attacker then attacks either target A or target B. The defender chooses a row for a strategy, and the attacker chooses a column. Both the sets of rows and columns

According to a research report conducted in 2011 (Laurence, 2011), Gartner (consulting firm focusing on processes of decision making) predicted that by the year 2015 more than half of organizations working with innovative methods will require methods of games in their internal processes. Consequently, a significant number of companies in the world will be using at least one application with features derived from games in the conduct of its business. This tendency to employ a mechanical interaction between people and

Game theory is an order directing to model circumstances in which decision makers need to make particular activities that have shared – perhaps conflicting – results [1]. It has been utilized basically as a part of economics, so as to model competition between organizations. In the setting of wireless networks, game theory may be utilized as an instrument for framing participation schemes among elements, such as nodes, terminals or network providers. Amid the most recent years, game theory has likewise been applied to networking, as a resort to take care of routing and resource

Game Theory (GT) is a technique of studying tactical decision-making. Technically, it is the study of arithmetical models of conflicts and collaboration between intelligent rational decision makers. (Thomas & Maurice, 2011). Therefore, the application of GT to wireless systems, the self-organizing problems of networks can be solved efficiently. Specifically, those problems that are more complicated and for which one cannot establish a systematic boundary by logic can be solved using SON. Most applications of Game Theory have been engaged in the fields of business, microeconomics management, decision-making and economics and finance in its early days (Aumann & Hart, 1992). Consequently, the concept of applying GT to WSN has grown in popularity among members of the academic world. Since the initial applications of Game Theory to Wireless Networks, it has become a critical
