What are the different strategies in game theory?
Therefore on the basis of outcome, the strategies of the game theory are classified as pure and mixed strategies, dominant and dominated strategies, minimax strategy, and maximin strategy.
What is secure strategy in game theory?
We say that a strategy profile (, ) is. secure if any rational deviation of player 2—i.e., a deviation that does not decrease her payoff—will not decrease. the payoff of player 1, and symmetrically, any rational deviation of player 1 will not decrease the payoff of player 2.
What is a strictly competitive game?
Aumann writes “Recall that a strictly competitive game is defined as a two-person game in which if one outcome is preferred to another by one player, the preference is reversed for the other. Since randomized strategies are admitted, this condition applies also to mixed outcomes (probability mixtures of pure outcomes).
Which of the following is the maximin solution of the prisoner’s dilemma game?
In the Prisoner’s Dilemma, the worst pay-off to Robin from confessing is to get 3 years (with Tom confessing), and the worst pay-off from denying is 10 years (with Tom confessing) – therefore the best of the worst is to confess. In this case, both the maximin and maximax strategies would be to confess.
