After reading a book, I believe everyone must understand a lot. Write a review and record your harvest and contribution. So how to write a post-reading feeling is more infectious? The following is a model game theory essay for your reference, hoping to help friends in need.
Game theory is a profound subject. For philosophers, it is philosophy; for military strategists, it is another Faust, and it is game theory.
I like game theory because I like thinking, I like fighting, and I don't like peace. I am eager to find what I want from game theory, and I am eager that game theory can guide my confused heart to a bright road.
I read game theory, although I don't know much about it, but I still understand the general meaning. Game theory is not a complete knowledge, but a tool to teach us how to think. It is a tool that allows us to pay attention to strategy and science when solving anything, instead of relying on feelings and intuition. Game theory allows us to go further and longer on the same road.
Game theory can also make people grow up, make people become rational and scientific when facing anything, and do everything with theoretical basis. It gives us a direction when making decisions, and we are no longer confused.
Game theory has no magic weapon to win by surprise, and there is no rock-breaking strategy; It is ordinary and charming, because it will make anyone who reads it gain something, and it will not be rewarded in vain. He is like a selfless people's teacher, treating all her students equally. Everyone who watches game theory should have a solemn heart, because it is teaching us!
I really hope that more people can find the beauty of game theory and let it lead more people to hope and success!
Game theory is a book I bought a long time ago. I turned it over and threw it aside. In recent days, because I can't wash it with my classmates, I decided to read this book carefully. After reading it, I realized that life is full of games, and I was gradually attracted by it. The cover of the book says: the purpose of learning game theory is not to enjoy the process of game analysis, but to win a better ending. My purpose is also it, let me get a better life ending, at least let me have a good eloquence.
Game theory is a science that studies how people make decisions and how this decision can reach a balance. Simply put, when deciding what action to take, each participant should not only act according to his own interests and purposes, but also consider the possible impact of his decision-making behavior on others and the possible consequences of others' reaction behavior, and seek the maximization of income or utility by choosing the best action plan.
Many phenomena in real life can be understood from the perspective of game theory. For example, the winner of Super Girl in 2006 was Laure Shang. Some people questioned that he did not have An Youqi's outstanding appearance, Chris Lee's stage charm to captivate the audience, and Sitar tan's "impeccable" singing skills. Then why did she win the championship? This reflects the skeptics' ignorance of game theory. This champion is not Laure Shang's, but the result of a * * * game between the organizer Hunan TV Station, Tianyue Media, participating girls, TV viewers, media and girls' fans.
Some people also think that there is the possibility of non-cooperative game and cooperative game in the whole competition process: some girls "fans" with lower scores join hands to deal with girls with higher scores; The player with the highest score will unite with the player who is sure to be hopeless to consolidate his position and prevent the next player with the highest score from overtaking.
However, game theory also has its limitations, because its basic assumption is that people are rational. In real life, people are often bounded rationality when making decisions. Nevertheless, people can still use game theory and information economics to analyze and solve problems.
Back to the topic, how to apply game theory to real life?
Prisoner's dilemma, when we are in the prisoner's dilemma, our strategy is in the dominant strategy, and the game reaches equilibrium on the basis that all participants choose the dominant strategy. For the "I" among the participants, we can use information asymmetry to throw the other party a choice, which can be divided into beneficial, useless and harmful, which will increase the risk of choice. For example, when we are at a disadvantage, revenge can play an effective deterrent role. Most participants' choices are useless and harmless. Even if the beneficial part is attractive, people are always reluctant to take risks, because the harmful damage is huge.
The purpose of game theory is clever strategy, not exposure. The purpose of learning game theory is not to enjoy the analysis process of game theory, but to win better results. Because the idea of game theory comes from real life, it can be expressed in a highly abstract way with mathematical tools, and can also be illustrated with daily examples and applied to life. Without profound knowledge of mathematics, we also become strategic experts in life by studying game theory.
There is a brain teaser question like this: When is zero greater than two, two greater than five, and five greater than zero?
The answer is: when playing with rock, paper, scissors.
Game is a strategy to use this game thinking to break through the seemingly unchangeable situation and solve serious problems in reality. In the game, each participant strives for his own best interests under certain conditions. The strong may not win the game, and the weak may not have a bright future forever, because in the game, especially in the game of multiple participants, the result depends not only on the strength and strategy of the participants, but also on the constraints and strategies of other participants. In fact, the game process is just a daily phenomenon. In our daily life, we often need to analyze other people's intentions to make reasonable behavior choices, and the so-called game is a process in which actors choose certain behaviors or strategies to implement and obtain corresponding results under certain environmental conditions and rules. Game theory is widely used. But as mentioned above, game theory was originally a branch of mathematical operation, and its research used various mathematical tools. How do ordinary readers master it?
There is a contradiction here. On the one hand, as Marx said, a science can only be considered truly perfect if it successfully uses mathematics. On the other hand, mathematics seems to be an insurmountable gap between game theory and ordinary people's lives.
Faced with this gap, many people either shrug their shoulders and walk away, and a few people will try to spend it by learning mathematics. But both of these reactions ignore a very simple truth: a person who can't program can still become a master of computer application, and without advanced mathematical knowledge, we can also become a master of strategy in life through the study of game theory.
Sun Bin didn't study advanced mathematics, but that didn't prevent him from using strategies to help Tian Ji win the horse race.
Game theory is first a set of logic that makes us think about the real world, and then a mathematical form makes this logic rigorous. The purpose of game theory is clever strategy, not solution. The purpose of learning game theory is not to enjoy the process of game analysis, but to win better results. In the final analysis, it is only game theory as a tool to analyze problems, and it is enough to simplify the problems and analyze them clearly.
On the other hand, because the creativity of the game comes from real life, it can be expressed in a highly abstract way with mathematical tools, and can also be illustrated with daily examples and applied to life. All the efforts made by the author of this book are to introduce the basic ideas and applications of game theory through common examples in daily life, and to seek ways to guide life decisions with this wisdom.
After reading this book, we can not only learn about the shocking real social trajectory, but also learn the most appropriate way to treat others.
Do you remember the last time you asked your boss for a raise, but you didn't know why? It's a pity that you didn't learn a little knowledge of game strategy at that time, which could have helped you raise your salary, and the increase exceeded your expectation.
Do you remember the last time you were disappointed by accommodating your girlfriend? If you apply the knowledge of game theory, you can get along better with her.
You don't know how to deal with a friend who always borrows money and never pays it back. Or how to bargain with business rivals?
Joseph; Ford once said: God rolls dice with the whole universe, but these dice are passive. It's true. Our main purpose is to understand how passive it is and how to use the "tricks" of game theory to achieve our goal to the maximum extent in this passive environment.
Recently, while sorting out the bookcases, I came across the book Game Theory, which I learned when I was a graduate student at Dongbei University of Finance and Economics. At that time, we were very lucky, and the college specially selected Professor Shi Yongdong, an excellent teacher from Dongbei University of Finance and Economics, to teach this course. Professor Shi was the youngest professor at Dongbei University of Finance and Economics at that time (at the age of 35, he was promoted to professor at the age of 32). He told us a very profound knowledge vividly. Until today, I can clearly remember his lecture style when I read it, but now I have a different feeling when I reread this book. At that time, I was trying to master the theory. Now I can understand the truth more calmly.
Game theory is a deep knowledge, which mainly studies how individuals get the most reasonable strategies in complex interactions. It has a wide range of applications, and the most common application should be economics. The theory in this book is profound, and the derivation of its mathematical model is more complicated. However, the cases in this book are simple and vivid, and are worth reading. Now give an example to analyze the truth and share the benefits with you.
This example is the story of "Smart Pig Game", which tells that there are two pigs, a big pig and a little pig in the pigsty. There is a pedal on one side of the pigsty. Every time you step on the pedal, a small amount of food will fall on the feeding port on the other side of the pigsty far from the pedal. If one pig steps on the pedal, the other pig has a chance to eat the food that has fallen on the other side first. As soon as the pig steps on the pedal, the big pig will eat all the food just before the pig runs to the trough; If the big pig steps on the pedal, there is still a chance for the little pig to run to the trough and compete for the other half before eating the fallen food.
So, what strategy will the two pigs adopt? The answer is: Piglets will choose the "hitchhiking" strategy, that is, they will wait comfortably in the trough; The big pig ran tirelessly between the pedal and the trough, just for a little leftovers.
What is the reason? Because, little pigs can get nothing by pedaling, but they can eat food without pedaling. For piglets, it is always a good choice not to step on the pedal whether the big pig does or not. On the other hand, the big pig knows that the little pig can't step on the gas pedal. It's better to step on the accelerator by himself than not to step at all, so he has to do it himself.
The phenomenon of "the little pig is lying down and the big pig is running" is caused by the rules of the game in the story. The core indicators of the rules are: the amount of food dropped each time and the distance from the pedal to the feeding port. If we change the core indicators, will there be the same scene of "pigs lying down and big pigs running" in the pigsty? Give it a try.
Change scheme 1: reduction scheme. Feeding is only half of the original weight. As a result, neither the little pig nor the big pig kicked. The little pig will step on it and the big pig will finish the food; If the big pig steps on it, the little pig will finish the food, too. Whoever pushes means contributing food to each other, so no one will have the motivation to push.
Variation scheme 2: incremental scheme. Feed twice as much as before. As a result, both the little pig and the big pig can pedal. Anyone who wants to eat will kick. Anyway, the other party won't eat all the food at once. Piglets and big pigs are equivalent to living in a materialistic society with relatively rich materials, and their sense of competition is not very strong.
Variant 3: Decreasing plus shifting scheme. Feed only half the original weight, but at the same time move the feeding port near the pedal. As a result, both the little pig and the big pig pushed hard. Those who wait will not eat, and those who work hard will get more. Every harvest is just a flower.
This story encourages the weak (pigs) in the competition to wait for the best strategy. But for the society, the allocation of social resources when piggy hitchhiked is not optimal, because piggy failed to participate in the competition. In order to make the most efficient allocation of resources, the designers of the rules don't want to see anyone hitchhiking, and neither does the boss of the company. Whether the phenomenon of "hitchhiking" can be completely eliminated depends on whether the core indicators of the rules of the game are set properly.
There are many examples in the book. By analyzing them, we can all realize some truth. Therefore, when reading, there will be a feeling that there are facts first and then theories. That is, we often say that theory comes from practice. The feeling is that this social phenomenon comes first, and then this theory is used to analyze it. This theory is just right for this social phenomenon.
