This chapter reviews games in extensive and normal forms. There are many situations involving conflicts of interests in the real world. In a conflict situation, each participant designs his/her own strategy of behavior, that is, expenditures on advertising and new technology, business spying, ...
Normal Form and Extensive Form Games: Normal form games represent the strategies and payoff in the form of a matrix or in a tabular form. The matrix represents the strategies take up by various players and their plausible result. These kinds of games are helping in identifying the dominated st...

Different extensive form games with the same reduced normal form can have different information sets and subgames. This generates a tension between a belief in the strategic relevance of information sets and subgames and a belief in the sufficiency of the reduced normal form. We identify a proper...
process of the games. Definition 2.2: The normal-form representation of an n-player game specifies the players strategies space S1,…, Sn and their payoff functions u1,…, un. We denotes this game by G={S1,…, Sn ; u1,…, un} In Investment of New Product , if the mark...
Game theory is the most common approach to studying strategic interactions between agents, but it provides little explanation for game-theoretical solution concepts. In this paper, we use a game-based argumentation framework to solve normal-form games. The result is that solution concepts in game ...
3.2Normal representation of extensive games Given an extensive-form game, one can construct a representation of that game in the strategic (normal) form. The resulting strategic game and the given extensive game have the same set of players and the same set of strategies for each player. The ...

(See the normal-form prisoners’ dilemma written as an extensive form game in Figure 8.17.) For greater ease of analyzing agent-specific strategy profiles, finding equilibria, and investigating other aspects of the interdependent structure of simple 2-person normal-form games, the matrix notation ...
Although recent work in AI has made great progress in solving large, zero-sum, extensive-form games, the underlying assumption in most past work is that the parameters of the game itself are known to the agents. This paper deals with the relatively under-explored but equally important "...
