博弈论中对所谓game有不同的描述形式:Normal form game用来表示一些Payoffs可以看做是Actions的函数的game,在这种game中Players往往同时采取行动(或可以看做是同时),而Extensive form game中引入了时间的概念,Players按次序采取行动,如扑克,象棋等。 这次我们先关注Normal form game,形式化定义一个可终止(Finite)的n主...
2 Computational aspects of Nash equilibria 2.1 Finite normal-form games We first introduce several concepts and notations. A finite normal-form game consists of a finite number of players, each with a finite number of pure strategies. When all players choose pure strategies simultaneously, each wil...
It is well known that Nash equilibria may not be Pareto-optimal; worse, a unique Nash equilibrium may be Pareto-dominated, as in Prisoners' Dilemma. By contrast, we prove a previously conjectured result: every finite normal-form game of complete information and common knowledge has at least ...

The Nash equilibrium leads to solutions that are logically inconsistent under the typical common-knowledge assumption of noncooperative game theory. A new concept of strategic equilibrium is introduced and it is shown that every normal-form game either has a unique equilibrium or the equilibrium is ...
We postulate that these heuristics are sensitive to the manipulation of those features that can be modified without altering the (Nash) equilibrium structure of the game. We call these features "descriptive". We test experimentally the effect of these descriptive features on both choice behavior and...
We recall that the only Nash equilibrium in (27) is a profile consisting of the players’ second strategies. Thus, the most reasonable result of the game is \((1,1,1)\). Similar to the best-known 2-person Prisoner’s Dilemma, the players would increase their payoffs if at least two...
