博弈论的含义是什么?What is the connotation of the game theory?
博弈论的定义：Definition of the game theory：
我们把动物利用大自然移动的瘾魂,在决策人期待的空间里,形成相对均衡的理论,称为博弈论（摘自《博弈圣经》中《人类未知的蓝色档案》一文）.
The theory of relative balance about the mobile addicts and soul of animals in the nature and in the expectation of decision makers is called the game theory.(quoted from the article “The Blue Files Unknown to Humankind” in Bible of Game Theory)

Game theory is a branch of applied mathematics that is used in the social sciences,most notably in economics,as well as in biology (most notably evolutionary biology and ecology),engineering,political science,international relations,computer science,and philosophy.Game theory attempts to mathematically capture behavior in strategic situations,in which an individual's success in making choices depends on the choices of others.While initially developed to analyze competitions in which one individual does better at another's expense (zero sum games),it has been expanded to treat a wide class of interactions,which are classified according to several criteria.Today,"game theory is a sort of umbrella or 'unified field' theory for the rational side of social science,where 'social' is interpreted broadly,to include human as well as non-human players (computers,animals,plants)" (Aumann 1987).
Traditional applications of game theory attempt to find equilibria in these games.In an equilibrium,each player of the game has adopted a strategy that they are unlikely to change.Many equilibrium concepts have been developed (most famously the Nash equilibrium) in an attempt to capture this idea.These equilibrium concepts are motivated differently depending on the field of application,although they often overlap or coincide.This methodology is not without criticism,and debates continue over the appropriateness of particular equilibrium concepts,the appropriateness of equilibria altogether,and the usefulness of mathematical models more generally.
Although some developments occurred before it,the field of game theory came into being with the 1944 book Theory of Games and Economic Behavior by John von Neumann and Oskar Morgenstern.This theory was developed extensively in the 1950s by many scholars.Game theory was later explicitly applied to biology in the 1970s,although similar developments go back at least as far as the 1930s.Game theory has been widely recognized as an important tool in many fields.Eight game theorists have won the Nobel Memorial Prize in Economic Sciences,and John Maynard Smith was awarded the Crafoord Prize for his application of game theory to biology.
