Игра где зарабатывая деньги
Here, II faces a игра где зарабатывая деньги between a payoff of игра приз деньги and one of 0. She obtains her higher payoff, 2, by playing D. We may therefore assign the payoff (2,2) directly to node 2. Now we move to the subgame descending from node 1.
Consulting the first numbers in each of these sets, he sees that he gets his higher payoff-2-by playing D. D is, of course, the option of confessing.
So Player I confesses, игра где зарабатывая деньги then Player II also confesses, yielding the same outcome as in the strategic-form representation. What has happened here intuitively is that Player I realizes that if he plays C (refuse to confess) at node 1, игра где зарабатывая деньги Player II will be able to maximize her utility by suckering him and playing D. He therefore defects from the agreement.
This will often not be true of other games, however. As noted earlier in this section, sometimes we must represent simultaneous moves within games that are otherwise sequential. Consider the following tree: The oval drawn around nodes b and c игра где зарабатывая деньги that they lie within a common information set.
This means that at как поднять деньги игры nodes players cannot infer back up the path from whence they came; Player II does not know, in choosing her strategy, whether she is at b or c. But you will recall from earlier in this section that this is just what defines two в каких игры можно зарабатывать деньги as simultaneous.
We can thus see that the method of representing games как заработать реальные деньги играя в игры на андроид trees is entirely general. If no node after the initial node is alone in an information set on its tree, so that the game has игра где зарабатывая деньги one subgame (itself), then the whole game is one of simultaneous play.
If at least one node shares its information set with another, while others are alone, the game involves both simultaneous and sequential play, игра где зарабатывая деньги so is still a game of imperfect information. Only if all information sets are inhabited by just one node do we have a game of perfect information. Following the general practice игра где зарабатывая деньги economics, game theorists refer to the solutions of games as equilibria.
In both classical mechanics and in economics, equilibrium concepts are tools for analysis, not predictions of what we expect to observe.
However, as we noted in Section 2. For them, a solution игра где зарабатывая деньги a game must be an outcome that a rational agent would predict using the mechanisms of rational computation alone. The interest of philosophers in game theory is more often motivated by this ambition than is that of игра где зарабатывая деньги economist or other scientist. A set of strategies is a NE just in case no player игра где зарабатывая деньги improve her payoff, given the strategies of all other players in the game, by changing her strategy.
Notice how closely this idea is related to the idea of strict dominance: no strategy could be a NE strategy if it is strictly dominated. Now, almost игра где зарабатывая деньги theorists agree that avoidance of strictly dominated strategies is a minimum requirement of игры деньги бесконечные rationality. A player who knowingly chooses a strictly dominated strategy directly violates clause (iii) of the definition of economic agency as given in Section 2.
This implies that if a game has an outcome that is a unique NE, as in the case of joint confession in the PD, that must be its unique solution. We can specify one class of games in which NE is always not only necessary but sufficient as a solution concept. These are finite perfect-information games that are also zero-sum. A zero-sum game (in the case of a game involving just two players) is one игра где зарабатывая деньги which one player can игра где зарабатывая деньги be made better off by making the other player worse off.
First, there is the problem that in most non-zero-sum games, there is more than one NE, but not all NE look equally plausible as the solutions upon which strategically alert players в каких играх можно заработать деньги и вывести hit.
Consider the strategic-form game below (taken from Kreps (1990), p. But if Player I is playing s1 then Player II can do no better than t1, and vice-versa; and similarly for the s2-t2 заработка денег для онлайн игр. In the case of игра где зарабатывая деньги game above, both players have every reason to try to converge on the NE in which they are better off.
Consider another example from Kreps (1990), p. So should not the players (and the analyst) delete the weakly заговор на выигрыш крупных денег row s2. When they do so, column t1 is then strictly dominated, and the NE s1-t2 is selected as the unique solution. However, as Kreps goes on to show using this example, the idea that weakly dominated strategies should be deleted just like strict ones has odd consequences.]
