In game theory, the extensive form is away of describing a game using a game tree.It’s simply a diagram that shows that choices are made at different points in time (corresponding to each node). The payoffs are represented at the end of each branch.
Extensive form games – MIT OpenCourseWare, Game theory I: Extensive form | Policonomics, Extensive-form game – Wikipedia, Game theory I: Extensive form | Policonomics, The extensive form of a game is an extension of a single-agent decision tree. We first give a definition that assumes the game is fully observable (called perfect information in game theory). A perfect-information game in extensive form or a game tree is a finite tree where the nodes are states and the arcs correspond to actions by the agents.
EXTENSIVE FORM GAMES Subgame perfect equilibrium De?nition: subgame perfect equilibrium (Selten 1965) A behavior strategy pro?le in an extensive form game is a subgame perfect equilibrium if for each subgame the restricted strategy is a Nash equilibrium of the subgame. Theorem Every ?nite game with prefect recall has at least one subgame …

Extensive form games contain the following: A game tree A list of players The names of players moving at each node A set of allowable actions at each node Payoffs specified at each node Unlike normal form games , it is easy to depict sequential moves by players in extensive form games . For example, here is a game where Player 1 moves first …
3/16/2010 · Game Theory: Lecture 12 Extensive Form Games Strategies in Extensive Form Games (continued) The following two extensive form games are representations of the simultaneous-move matching pennies. The loops represent the information sets of the players who move at that stage. These are imperfect information games .
