If you are talking to your lover on your mobile phone, the signal is suddenly cut off. At this time, will you call immediately or wait for your lover to call? Obviously, whether you should call or not depends on whether your lover can call or not. If one of you wants to dial, then the other party had better wait; If one party is waiting, then the other party had better dial. Because if both parties dial, then the line will be busy; If both sides are waiting, then time will pass by in waiting. This is the game! This is the preface of the book The Game Around. I once came across this book in the library, with a yellow shell and several interesting prefaces. I have heard about the game for a long time. It is a rigorous science and profound knowledge. Here, Professor Dong Zhiqiang described it as such a plain and simple life. So I read it with curiosity. Later, I learned that Mr. Dong wrote this book for his wife, a graduate student who is not good at math but likes playing games. So Mr. Dong, with his solid professional knowledge and extensive knowledge, wrote a popular game theory book without mathematical threshold without the help of mathematical model. The "game around" begins with the phone call of the lover. This approachable style runs through the book, telling the theory and its application in the form of stories, so that everyone interested in games can avoid boring theories and find the fun of game life. Find a happy study and a happy game life. Teacher Dong's game theory covers the basic category of complete information game theory. There are nearly 100 interesting stories in the book, and some basic concepts of blog theory are given in the right time and space, which makes us feel the exquisite and ingenious pleasure of the game in the corridors of history, humanities, politics, military affairs, economy, management, psychological behavior and other fields all over the world! Among them, "prisoner's dilemma" has a special meaning. The author comes from a typical example. Two people were arrested for theft, and the police suspected that they had committed robbery, but they did not get conclusive evidence to prove that they had committed robbery unless one or both confessed. If both of them don't confess, they can only be convicted of petty theft. Prisoners are separated and examined, and they are not allowed to exchange information with each other. The policy is this: if both of them confess, everyone will be sentenced to two years in prison for robbery and theft; If both of them refuse to confess, they will be sentenced to half a year's imprisonment for robbery (which is undoubtedly the best result for criminals); If one party confesses and the other party refuses to confess, it is considered that the confessor has made meritorious deeds and will not be punished. Those who refuse to confess will be severely punished for robbery, theft and resistance for five years. So every prisoner will think that if the other party refuses to confess, he will be liberated immediately, and if he refuses to confess, he will be sentenced to half a year, so confession is a better choice. If the other party confesses, confession will be sentenced to two years, and refusal to confess will be sentenced to five years, so confession is still a better choice. Then they will find that whether the other party confesses or refuses to confess, it is always the best choice to choose their own confession. such

Every prisoner will find that confession is his better choice. So the stable result of the game is that both prisoners will choose to confess. This makes me find that we will also face the prisoner's dilemma in our lives. For example, in our exam-oriented education, a school can choose quality education or exam-oriented education. If all schools choose quality education, it will be better for training talents. However, in view of the quality education in other schools, choosing exam-oriented education can achieve excellent results in exams such as entering higher schools; In view of the fact that other schools choose exam-oriented education, only by choosing exam-oriented education can we not fall behind too much in the entrance examination. As a result, every school is caught in the prisoner's dilemma of choosing exam-oriented education. In fact, everyone is dealing with others every day, or competing or cooperating. In such a highly interactive environment around us, we are constantly playing games with others every day, whether with our relatives, classmates, colleagues and leaders, in our future work. With its easy-to-understand language and vivid examples, I have a preliminary understanding of the game and have a great interest in it. It inspires us to learn games, understand games and apply game knowledge to our lives. Games let us treat life more rationally and learn more intelligently. It has taught us how to deal with the "games around us" in a complicated society, so that we can handle all kinds of affairs with ease and stand out in the collective!
