Chapter 87 The Arrival of Ma Yun (seeking support, third more

Unexpected guests attracted Chen Fan.

"I know you, Alipay is really powerful, and it has changed the pattern."

"It's nothing, I'm here to ask, what is the economic situation you mentioned?"

Chen Fan thought for a while and said, "If I want to, I will hold a speech in Dubai. The new theory for me is also a new interpretation of game theory. If you like, let's go."

After speaking, Chen Fan returned to the laboratory and mumbled his paper.

Goldbach’s conjecture was completed, so the paper, Chen Fan decided to use this game theory as his paper.

If you use Goldbach's conjecture, it is actually possible, but Chen Fan is a Xueba, and Xueba will not do such tricks.

Challenge, progress.

It is the core, game theory, Chen Fan does not know what will bring him, but mathematics, Chen Fan feels that he has risen to a higher level.

The horse arrived and was driven away. This incident caused a big disturbance on the Peking University side.

"Am I wrong?"

"Maybe you heard it right, others may not, but Chen Fan is different."

"Why is it different?"

"I heard that Buffett called Chen Fan."

"Brother, stop making trouble. Chen Fan is an academic, and they make money. These two are different. Don't you tell me that Chen Fan can teach others to make money? Isn't this a pyramid scheme?"

Some people believe it, some people don't believe it, but this will not affect Chen Fan's travel in the slightest.

Using the official account of Peking University, Chen Fan posted an explanation that he would give a game theory speech at the St. John's Lecture Hall in Dubai.

The St. John’s Lecture Hall used to perform concerts. This time, especially because of Chen Fan, the concert was cancelled and turned into a lecture.

Everyone has a new understanding of Chen Fan's current worth.

And Chen Fan also got on the plane to Dubai.

"Promise to Saudi Arabia, naturally I will do it."

Hua Xiong said: "The country agrees and hopes you will perform well. This is agreed upon."

"What's the price?"

"The purchase order also has some sales rights of Qiu Hua Company in Dubai."

Chen Fan nodded. These people will repay themselves, but it will not be monetary, but some other convenience.

This practice is recognized in Tao Yaoyao as the basis of social interaction.

"So, why is she here?"

Anna cocked her legs and looked at Chen Fan.

She wore more boldly today, and didn't care about her perfect figure being watched by Chen Fan.

"I heard you like me."

"No, I just said that your figure and appearance are in line with the golden ratio. It's beautiful, but it doesn't mean you like it."

"I'm sure you like it, because Tao Yaoyao told me."

Chen Fan has a headache again, why does Tao Yaoyao want to say this?

Hua Xiong saw it in his eyes and was very happy in his heart.

Mathematicians are not good people. You must know that mathematics geniuses will have many companions or lover identities. This is the meaning of Sharon's existence.

Has become a tradition.

Why don't they blame themselves, because mathematics is rational, so rational that they believe that they are strong enough and proud of themselves, so they should have so many beautiful women likes.

So in the end Nobel lost to a mathematician.

On the plane, Chen Fan chose to ignore Li Anna, this woman, Chen Fan really felt a little pain in her head.

The sudden appearance broke some of Chen Fan's plans.

"How are you preparing?"

"I have prepared sixty-six cases and analyzed them. I think this should be enough."

"Tell me."

Chen Fan frowned, and Anna said, "I am a Nobel nomination, do you think I gave it for nothing?"

Tao Yaoyao pulled Anna here, and Anna said angrily: "You man has weaknesses all over, and all girls hate it."

"But he is good enough."

"Taoyaoyao, I admire you, I think you can walk better, but I don't want you to lose yourself."

"So, are you still talking about topics?"

Anna chose to shut up.

Chen Fan said: “According to the actual situation of my country’s telecommunications industry, let’s construct a game model for the price war in the telecommunications industry. Suppose the participants in this game are telecommunications operators A and B. They compete in a certain field of telecommunications. The prices are all P0. A (Telecom) is an established company with strong strength and occupies most of the market share; B (Unicom) has just been established, and its wings have not grown strong. It is the government that was established to break the monopoly and encourage competition. of.

Just because B was fostered by the government to encourage competition, B got some preferential treatments from the government, including B’s price.

The grid can be 10% lower than P0. This move will not have much impact on A, because A's foundation is too strong. Under such a market distribution, A and B can reach a balance, but due to B's price advantage, the market share has gradually grown, and to a certain extent, A has been affected. What should A do at this time? Let’s assume:

...

Chen Fan didn't say it very quickly, and tried his best to make Annan understand.

"According to these conditions as you said, then the algorithm will actually come out soon."

Chen Fan handed her a piece of paper.

Anna said: "A reduces the price and B maintains, then A gains 15.

B loses 5 and gains 10 overall;

A maintains and B also maintains, then A gains 5, B gains 10, and the overall gains 15;

If A maintains and B lowers the price, A loses 10, B gains 15, and the overall gains 5;

If A drops in price and B also drops in price, then A loses 5, B loses 5, and overall loses 10.

From the perspective of A, it is obvious that a price reduction is better than maintenance, and a price reduction can at least guarantee better than B. In the case of equal probability, A’s price reduction income is 15×50%-5×50% = 5, and the maintenance income is 5× 50%-10×50%=-2.5. In order to maximize its own interests, A inevitably chooses to cut prices. From the perspective of B, the effect is the same. Price reduction is also better than maintenance. Its price reduction income is 5, and maintenance income is 2.5. It will also choose to reduce prices. In this round of the game, A and B both use price reduction as a strategy, so each loss is 5, the overall loss is 10, and the overall return is the worst. This is the final Nash equilibrium of this game. The price war game model we constructed in the telecommunications industry is a typical prisoner's dilemma phenomenon. Each part seeks to maximize the benefits, but the overall benefits are not optimal or even the worst.

Chen Fan said: "The calculation is basically correct. According to the current calculation theory, this is correct and the most realistic. However, reality and books are two concepts. 0..."

"Yes, this is what the Nash equilibrium cannot do, because Nash represents absolute rationality. Economics all say it is a number game, but a pure number game is also emotional."

"Popular reputation, traditional concepts, and the acceptance of new things by users in different cultures are all influences, of course, as well as the share of advertisements, etc."

"Yes, you are right, but how can these be solved?"

"Need to wash a"

"Why is the coefficient a? Also, Chen Fan, the art you named is really bad. You can use Babylonian mathematics or Greek mathematics. Why is it a simple number a."

Chen Fan said: "It's just a symbol, why should it be so true?"

"You go on, I want to know what proportions you said, of course you don't have to say it."

Chen Fan shared the proportion.

Anna was surprised, and then began to calculate.

With the intervention of new data, this problem becomes a very delicate mathematical calculation problem.

It's big, it's big.

It's also very complicated.

Because of these complexities, Anna felt that the final number might be very accurate.

"This is 89.3%. It is possible to make a profit. It is impossible. How can such a figure be calculated?"

Anna didn't believe it, she found some cases of official telecommunications, and after comparing them, she found that the numbers were so close.

"You...is this game theory?"

'Yes, this is game theory. There are two kinds of game theory. The first one is single-win and selfish. Before the Nash equilibrium, the second is a win-win. The Nash equilibrium gives a win-win theory. The third, I The title is exclusive, that is, I must win, and the ratio of winning is infinitely close to 100%. ’

Humanities, geography, environment, etc., all factors that can be considered have been considered.

"Why are the winter figures so low?"

"Domestic wiring will be damaged in winter, and the comfort level of natural people will be reduced."

"Then why did it increase again in summer?"

"Lines are organized in spring, and summer is a period of skyrocketing. At this time, the proportion of people in travel and tourism has increased, and the utilization rate has also increased."

"Madman, you are a madman. This is the application of simple prisoner theory. Why do you need to be complicated? In this way, game theory will become a very heavy subject, and it will become an impossible subject."

Hua Xiong said, "What are you talking about?"

Anna said: "You study quantum physics, I understand, but you have to understand that if everyone is a stock god and everyone is Buffett, then stocks don't need to exist."

Hua Xiong's back was numb. It turned out that it was so dangerous this time.

"Isn't that, the purpose of the group of people is to see how Chen Fan solves this mortal situation?"

Anna couldn't control her emotions a little, and said, "Chen Fan is a madman, a madman through and through, a terrifying madman. His theory shouldn't have appeared. It has exceeded the times too much. This theory appears, don't Talking about changes in the economic structure, it may even be possible to completely reshuffle the economic structure."

"Chen Fan, or, let's go back."

Hua Xiong is a little worried.

Chen Fan said: "It's okay, I know it in my heart."
