What is terminal history in game theory?

the set of all sequences of actions that can possibly occur, the player who moves at each point in each sequence. Each possible sequence of actions is a terminal history.

How many subgames are there in this game?

a) There are 6 proper subgames in this game.

What are the subgames in this game?

In game theory, a subgame is a subset of any game that includes an initial node (which has to be independent from any information set) and all its successor nodes. It’s quite easy to understand how subgames work using the extensive form when describing the game.

Can there be multiple SPNE?

This lecture shows how games can sometimes have multiple subgame perfect equilibria. Most games have only one subgame perfect equilibrium, but not all. When players receive the same payoff for two different strategies, they are indifferent and therefore may select either.

What is extensive form in game theory?

An extensive-form game is a specification of a game in game theory, allowing (as the name suggests) for the explicit representation of a number of key aspects, like the sequencing of players’ possible moves, their choices at every decision point, the (possibly imperfect) information each player has about the other …

What is a subgame game theory?

In game theory, a subgame is any part (a subset) of a game that meets the following criteria (the following terms allude to a game described in extensive form): It has a single initial node that is the only member of that node’s information set (i.e. the initial node is in a singleton information set).

What is a perfect information game?

A class of game in which players move alternately and each player is completely informed of previous moves. Finite, zero-sum, two-player games with perfect information (including checkers and chess) have a game saddle point, and therefore one or more optimal strategies.

Is every Nash equilibrium Subgame perfect?

Definition 11.1 A Nash equilibrium is said to be subgame perfect if an only if it is a Nash equilibrium in every subgame of the game. The third subgame is the game itself. Note that, in each subgame, the equilibrium computed via backward induction remains to be an equilibrium of the subgame.

Is it an advantage to move first or last in a sequential game?

Many times, by moving first, a player can determine the direction of the game — forcing other players to then react to that choice rather than moving on independently. However, not all sequential games have a first-mover advantage. In fact, some have a second-mover advantage.

What can we learn from game theory?

Game theory is a framework for understanding choice in situations among competing players. Game theory can help players reach optimal decision-making when confronted by independent and competing actors in a strategic setting.
