City: Me, IQ 300

Chapter Eighty-Seven The Arrival of the Horse (Ask for support, third more.)

The unexpected guest attracted Chen Fan.

“I know you, Alipay is really powerful and has changed the pattern.”

“This is nothing, I’m here to ask, what is the economic pattern you said?”

Chen Fan thought for a moment and said: “If you want to, I will hold a speech in Dubai, for my new theory, but also a new interpretation of game theory, if you want, just pass.” ”

After that, Chen Fan returned to the laboratory from the new and muttered his paper.

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

If you use Goldbach to guess, it is actually possible, but Chen Fan is a top student, and a top student will not do such a tricky thing.

Challenge, progress.

is the core, game theory, Chen Fan does not know what it will bring to himself, but mathematics, Chen Fan feels, he has risen to another level.

The horse arrived, and then was driven away, and this matter, on the side of Peking University, set off a small storm.

“Did I hear you wrong?”

“Maybe you heard it right, others may not be able to, but Chen Fan is different.”

“Why is it different?”

“I heard that Buffett called Chen Fan.”

“Big brother, don’t make trouble, Chen Fan is an academic, people make money, these two are different, do 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 at all.

Chen Fan used the official account of Peking University to send 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 do concerts, but this time, especially because of Chen Fan, the concert was canceled 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 the Saudis, naturally I will do it.”

Hua Xiong said: “The state agrees, and hopes that you will behave well, and this is agreed.” 、”

“At what cost?”

“Purchase orders, and some sales rights of Qiu Hua in Dubai.”

Chen Fan nodded, these people will return themselves, but it will not be financial, but some other aspects of convenience.

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

“So, why is she here?”

Anna stretched her legs and looked at Chen Fan.

She was dressed more boldly today, not caring at all about her perfect body being watched by Chen Fan.

“I heard you liked me.”

“No, I’m just saying that your figure and appearance are in line with the golden section and are very beautiful, but it doesn’t mean you like it.”

“I’m sure you like it, because Peach told me.”

Chen Fan had a headache again, why did Tao Yaoyao say this?

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

Mathematicians are not good people, you know, mathematical geniuses will have many partners, or lovers, and Sharon’s existence is just that.

It has become a tradition.

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

So in the end, Nobel lost to mathematicians.

On the plane, Chen Fan chose not to take care of Anna, this woman, Chen Fan really felt a little brain pain.

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

“How are you prepared?”

“I prepared sixty-six cases and analyzed them, and I thought, that should be enough.”

“Talk to me.”

Chen Fan frowned, and Anna said: “I’m a Nobel nominator, do you think I gave it for nothing?” ”

Taoyao pulled Anna here, and Anna said angrily: “You man, full of weaknesses, full of points that girls annoy.” ”

“But he’s good enough.”

“Taoyao, I admire you, I think you can walk better, but I don’t want you to lose yourself.”

“So, you still can’t talk about the subject?”

Anna chose to shut up.

Chen Fan said: “According to the actual situation of China’s telecommunications industry, let’s construct a game model of price war in the telecommunications industry. Suppose that the participants in this game are telecom operators A and B, and they compete in a certain area of telecommunications, and the price is P0 at the beginning. A (telecom) is an established enterprise with strong strength, occupying the vast majority of the market share; B (Unicom) has just been established, and its wings have not yet grown, and it was established by the government to break monopoly and encourage competition.

It is precisely because B is supported by the government to encourage competition, so B has received some preferential treatment from the government, including the price of B

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 market distribution, A and B can achieve a balance, but due to B’s advantage in price, the market share gradually grows, to a certain extent, which affects A. At this time, what should A do? Assume that:

……

Chen Fan did not say very quickly, and tried his best to make Annan understand.

“According to these conditions you said, then in fact, the algorithm can come out soon.”

Chen Fan handed her a piece of paper.

Anna said: “A lowers the price and B maintains, and A makes a profit of 15.

B loss 5, overall profit 10;

If A maintains and B also maintains, then A makes a profit of 5, B makes a profit of 10, and the overall profit is 15;

If A maintains and B decreases, A loses 10, B gains 15, and the overall profit is 5;

If A reduces the price and B also reduces the price, A loses 5, B loses 5, and the overall loss is 10.

From A’s point of view, it is obvious that the price reduction is better than maintenance, the price reduction can at least guarantee that it is better than B, in the case of equal probability, the income of A price reduction is 15×50%-5×50%=5, the income of maintenance is 5×50%-10×50%=-2.5, in order to maximize its own interests, A inevitably chooses to reduce the price. From the perspective of B, the effect is the same, the price reduction is also better than maintenance, its price reduction income is 5, the maintenance income is 2.5, it will also choose to reduce the price. In this round of the game, both A and B will reduce the price as a strategy, so each loses 5, the overall loss is 10, and the overall gain is the worst. This is the Nash equilibrium that eventually emerges from this game. The price war game model of the telecom industry constructed by us is a typical prisoner’s dilemma, in which each part seeks to maximize the benefits, while the overall interests 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, but reality and books are two concepts.” ”

“Yes, this is where Nash equilibrium cannot be done, because Nash represents absolute rationality, economics says that it is a numbers game, but a simple number game is also emotional.”

“Word of mouth, traditional concepts, acceptance of new things by people in different cultures, these are influences, of course, the share of advertising and so on.”

“Yes, you’re right, but how to solve these?”

“Need to wash a”

“Why coefficient a? Also, Chen Fan, the art of your name is really bad, you can use ancient Babylonian mathematics, you can also use Greek mathematics, why is it a simple number a. ”

Chen Fan said: “It’s just a symbol, why should it be so real?” ”

“You go on, I want to know what the proportion of what you said, of course you can not say.”

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.

Big, big.

It’s also very complicated.

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

“This is 89.3 percent, the possibility of profit, this is impossible, how can such a figure be calculated?”

Anna didn’t believe it, and 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, win-win, selfish, before Nash equilibrium, the second win-win, Nash equilibrium gives a win-win theory, and the third, I call it exclusive, that is, I must win, and the proportion of wins is infinitely close to 100%. ’

Humanities, geography, environment, etc., all the factors that can be considered are taken into account.

“Why are the numbers low in winter?”

“If the domestic line is laid, there will be damage in winter, and the comfort of natural people will be reduced.”

“Then why is the summer increasing again?”

“Spring to sort out the route, summer is the stage of skyrocketing, at this time everyone for travel, the proportion of tourism increases, and the utilization rate increases.”

“Madman, you are crazy, this is the application of simple prisoner theory, why do you have to complicate, so that game theory will become a very heavy discipline, and will become an impossible discipline.”

Hua Xiong said: “What are you talking nonsense? ”

Anna said: “You study quantum physics, I understand, but you also 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 this time it was so dangerous.

“Isn’t that the purpose of that group of people coming is to see how Chen Fan solves this mortal situation?”

Anna was a little unable to control her emotions and said: “Chen Fan is a madman, a complete madman, a very terrifying madman, his theory, should not appear, this has exceeded the times too much, this theory appeared, not to mention the change of the economic pattern, and may even completely reshuffle the economic pattern.” ”

“Chen Fan, or else, let’s return.”

Hua Xiong was a little worried.

Chen Fan said: “It’s okay, I know it in my heart. ”

ps: Please support, thank you all.
