Some authors, particularly in introductory textbooks, initially define the extensive-form game as being just a game tree with payoffs (no imperfect or incomplete information), and add the other elements in subsequent chapters as refinements. Whereas the rest of this article follows this gentle approach with motivating examples, we present upfront the finite extensive-form games as (… WebSubgames • A subgame is a part of an extensive form game that constitutes a valid extensive form game on its own Definition A node x initiates a subgame if all the information sets that contain either x or a successor of x contain only nodes that are successors of x. The subgame initialized at x is the extensive form game conformed by …
