从"纳什均衡"的普遍意义中我们可以深刻领悟司空见惯的经济、社会、政治、国防、管理和日常生活中的博弈现象。一般的博弈问题由三个要素所构成:即局中人又称当事人、参与者、策略等等的集合,策略集合以及每一对局中人所做的选择和赢得集合。其中所谓赢得是指如果一个特定的策略关系被选择,每一局中人所得到的效用。所有的博弈问题都会遇到这三个要素。
From the " Nash equilibrium" in the general sense we can understand the profound common economic , social, political , defense , management and daily life game phenomenon . General game questions posed by the three elements : the choices made by the players , also known as a collection of the parties , participants, policies , etc. , as well as a collection of strategies to win every game and human collections. Which is the so-called win if a specific policy is selected relationship , each of the players of the obtained effect. All games will encounter problems of these three elements .

毕竟,博弈论是数学,更确切地说是运筹学的一个分支,谈经论道自然少不了数学语言,外行人看来只是一大堆数学公式。好在博弈论关心的是日常经济生活问题,所以不能不食人间烟火。其实这一理论是从棋弈、扑克和战争等带有竞赛、对抗和决策性质的问题中借用的术语,听上去有点玄奥,实际上却具有重要现实意义。
After all, the mathematical game theory , more specifically, a branch of operations research , natural and ultimately on the road to talk through the language of mathematics , a layman it seems just a bunch of mathematical formulas . Fortunately, game theory is concerned with the daily economic life problems, so can not otherworldly . In fact, with this theory is chess from , etc. , poker and war contest , issues and decision-making nature against the borrowed term sounds a bit mysterious , in fact it has important practical significance. Game Theory Masters look like a game of chess economic and social problems , often blending profound truth in the game. So, more from our everyday life common things start to our side of the story as an example , meanders , not boring. Saying that one day , a rich man was killed at home , belongings stolen. Police in the case of the detection process , caught two suspects , Pascal Faith and that Coors and found the victim 's family lost their belongings from the residence . However, they have killed people denied , arguing that millionaires are first found slain , then just stole something to pilfering . So the police will isolate the two were locked in a different room trial. Talk to each person individually and separately by the local prosecutor. Prosecutors say , "Because you have conclusive evidence of theft crime , so you can be sentenced to one year imprisonment , but I can make a deal with you if you separate crime to kill Frankly , I sentence you to three months only imprisonment , but your accomplices to criminal sentenced to ten years if you refuse to confess , being accomplices to report , then you will be sentenced to ten years sentence , he only sentenced to three months in prison , but if you both confessed , then you should be sentenced to five -year sentence .(责任编辑:cari)
