Incomplete-information Static Games
Game theory is a complex mathematical tool used to measure the strategic interactions between two or more players. It is used in a variety of ways across different fields, such as economics, political science and psychology. One particular aspect of game theory is the study of incomplete-information static games. These types of games involve players whose information about other players’ strategies is limited or unavailable.
In many cases, such games involve two players (or more) with one not knowing the strategy of the other. For example, imagine a game of poker in which one player has no knowledge of the other player’s cards. In such a situation, the player who is unaware of the other’s cards must rely on his or her own strategy to determine which action to take. This process is known as “strategic reasoning” and is a key element in the study of incomplete-information static games.
In general, incomplete information games are more difficult to analyze than other types of games because of the lack of complete information. Most incomplete information games require extensive study and modeling in order to accurately analyze the situation. As a result, the results of these games can often be unpredictable and the strategies often change as the game progresses. This means that the strategies used in one game might not work in another game.
In order to accurately analyze incomplete-information static games, researchers must first identify all of the players, the strategies available to each player, the strategic reasoning process and the payoffs associated with each strategy. This process is known as “model building.” After model building, the researcher can then use various analytical techniques to determine the best strategy or strategies for each player.
One such technique is “iterative elimination of dominated strategies,” which seeks to eliminate strategies that are not optimal for any player. Other techniques that can be used when analyzing incomplete information games include dominance solvers and evolutionary algorithms.
Incomplete-information static games can be used to analyze a variety of interactions, from decision-making in business to military engagements. It can also be applied to more everyday situations, such as sports competitions. Understanding the strategies of incomplete information games can lead to greater insight into the behavior of people and organizations in different contexts.
