Abstract

Game theory is the formal study of conflict and cooperation, first time introduced as long back as 1921 by mathematician Emile Borel, then enriched in 1928 by von Neumann and Oskar Morgenstern, and much enriched by Josh Nash, has enormous applications, including    in business, and even in the prediction of election results, etc. The game playing is also a search process. The chapter presents the classes of games as combinatorial and games of chance, then further as zero-sum games and non-zero-sum games, the prisoner’s dilemma, game playing strategies, the games of perfect information, arbitration scheme in games, minimax search in game playing, and analysis of specific games like tic-tac-toe. The more efficient search processes like alpha and beta are presented, as well as the alpha cutoff and beta cutoff methods to prune the search process are presented and analyzed, followed with chapter summary, and an exhaustive list of exercises along with a number of multiple-choice questions provided at the end.

1
A player can learn from the opponent’s past moves as to how and what strategy the opponent followed. But, this requires the learning ability. Hence, the game’s moves shall not be based current state, but past also. This has not been considered for the present discussion.
 
2
This information is helpful to players to choose alternative moves.
 
3
Selection of minimum of the payoffs or maximum of the payoffs (depending on which player has a move) of children of any node \(v_k\) and moving it to node \(v_k\), is called backing-up of values.
