周末了，再來回顧一部喜歡的片子 --- A Beautiful Mind | 視聽世界

前幾天看了一部Russell Crowe 主演的片子,突然就想起了他曾經主演的另一部俺很喜歡的片子 -- A Beautiful Mind。居然在YOUTUBE 上找到FREE 的了,於是又復習了一遍,還是那麼好看,一口氣復習完。

A Beautiful Mind ( 2001) 是一部以NOBEL 1994年經濟學得主John Nash 的生平改編的影片。這是一個天才也是一個精神病人的故事。不多說了,自己看吧。

這個就是讓他贏得NOBEL獎金的那個著名理論,片子裡有講。

In game theory, the Nash equilibrium is a solution concept of a non-cooperative game involving two or more players, in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only his own strategy unilaterally. If each player has chosen a strategy and no player can benefit by changing his or her strategy while the other players keep theirs unchanged, then the current set of strategy choices and the corresponding payoffs constitute a Nash equilibrium.

Stated simply, Amy and Phil are in Nash equilibrium if Amy is making the best decision she can, taking into account Phil's decision, and Phil is making the best decision he can, taking into account Amy's decision. Likewise, a group of players are in Nash equilibrium if each one is making the best decision that he or she can, taking into account the decisions of the others.
