WebGames in extensive form often involve each player being able to play multiple moves which results in the formation of multiple information sets as well. A player is to make choices at each of these vertices based on the options in the information set. WebIn this Chapter we start to look at extensive form games in more detail. Extensive form games. If we recall Chapter 1 we have seen how to represent extensive form games as a tree. We will now consider the properties that define an extensive form game game tree: Every node is a successor of the (unique) initial node.
