"Lu Yuxin?" Upon hearing this name, several teachers in the conference room were stunned, and Han Wenle's expression became even more relaxed.

Before Wang Yufei appeared, this girl was a genius who had not appeared in the provincial capital No. 1 Middle School for a hundred years!

If it weren't for this girl's insistence that she hadn't considered which school to go to yet, she would have been recruited by a top university in China through special recruitment.

This girl gave Wang Yufei an extremely difficult question, and everyone believed her.

However, those who study mathematics must have the belief to get to the bottom of the casserole. Han Wenle subconsciously asked: "What question?"

"Strictly speaking, it is not a pure mathematical question, but it is related to mathematics. She listed a lot of data for me, as well as K-line charts, and asked me to make a mathematical model in a week, which can roughly predict the next financial situation.

The direction of the data." Wang Yufei answered truthfully.

"Designing mathematical models? Predicting trends?" Han Wenle was shocked. What are children thinking about now? Do high school students need to study these?

Not only Han Wenle, but the principals next to him, Lao Guo, and Lao Gao probably have bigger question marks in their minds.

Are these things still taught in Mathematical Olympiad classes now?

At this point, Guo Jianfeng probably understood why Wang Yufei went to the library to learn about these materials yesterday. But at this moment, his mind was even more confused.

After all, he was the one who brought Wang Yufei out of Daowang Village. How long has it been since he started studying such high-end things? If this mathematical model can really be researched, wouldn't it be possible to make a fortune just by stock trading?

"Do you think you can solve Lu Yuxin's problem?" Han Wenle calmed down and asked.

"I wasn't clear on some concepts before, but now I understand them. I don't dare to say that I can solve it, because there is no completely correct answer to this question. I can only try to improve the model as much as possible. Because in the real financial market, it affects the unit time data.

There are too many factors that fluctuate. But if we do not consider sudden factors and make a model that can judge a longer unit time, I have a little bit of confidence. Of course, to make the subsequent K-line as close as possible, data must be supplemented at all times."

Wang Yufei said very honestly.

"Come here, show me the questions she asked and your design ideas!" Han Wenle demanded unbelievingly.

Wang Yufei glanced at Guo Jianfeng in embarrassment. Lao Guo unkindly ignored Wang Yufei's look for help. His curiosity had also been aroused. He wanted to know how this genius he had accidentally discovered in just one night

How far can it be achieved?

"Okay." Wang Yufei nodded resignedly, and then picked up the pen again.

"These are the data and conditions listed by Yu Xin."

Wang Yufei relied on his memory to quickly write down the question Lu Xinyu asked yesterday, and also drew the picture.

This move once again left several teachers speechless.

What kind of terrifying memory is this? You must know that the data listed by Lu Yuxin are different from the questions Li Zesheng presented. All kinds of trivial data are almost densely packed on a whole page, but Wang Yufei completely relies on his brain to restore it.

What kind of monsters are they?

"My current thoughts are as follows. First of all, I am sure that this is a very huge project, so my first step is to decompose it. First, I need to establish a most basic and simple volume and price fluctuation model. The formula is like this...

"

"The second step is to establish a basic evaluation model, assuming that p is the average value of the valuation, and record the peak and bottom values ​​of fluctuations in as many units of time as possible, and then use this formula..."

"In the third step, I designed a capital variable introduction model. The significance of this model is to analyze the inflow and outflow of capital per unit time as detailed as possible. The formula is as follows..."

"The fourth step...the fifth step...the sixth step..."

…

Wang Yufei explained his ideas in a clear and logical manner, and the notebook given to him by Principal Wang was consumed quickly. What was written on the paper were only simple graphics and formulas, but if he could follow Wang Yufei's ideas, he could naturally construct them in his mind.

An extremely complex model.

This model can be imagined as an irregular three-dimensional building built up of small wooden sticks. Each small wooden stick supports and bears force on each other. If any one is pulled out, the irregular building will collapse immediately.

But it looks like this building is so wonderful. Although there may still be many shortcomings in some places, if you spend more time thinking about it and perfecting it, one day it will become a nearly perfect building.

It's a pity that no one on the scene can keep up with Wang Yufei's rhythm, or ideas. At first, Han Wenle could keep up, but when more and more functions and variables were introduced, and the buildings became taller and taller, Han Wenle could not keep up.

Le's brain started to be unable to keep up...

Looking at Wang Yufei who was still talking about his thoughts, Han Wenle suddenly felt that if this little guy was given as detailed data as possible and huge computing power, would this guy really be able to create a system that could accurately predict the rise and fall of the stock market?

The mathematical model comes out!

Of course, this is an illusion.

As Wang Yufei said before, there are too many variables, and any emergencies may have unpredictable fluctuations in stock prices in the short term. However, if these short-term fluctuations are not considered and only long-term predictions are made...

Could this little guy become a great fund manager in the future?

"Stop! Needless to say, did you think of these all last night?" Han Wenle looked at the densely written data and formulas in the notebook and once again had doubts about life.

"Yes, but it is still very incomplete. There are still many key issues that cannot be solved. This problem becomes more complex the deeper it goes in. There are too many influencing factors, many of which may interfere with each other. There are still many areas that need to be improved." Wang Yufei sighed.

road.

Han Wenle didn’t want to talk anymore, he was really tired!

He was probably already sure that the boy in front of him and Lu Yuxin must not have attended the class yesterday.

He didn't even know whether the teacher should be happy or depressed when meeting such a student!

But if you think about it from another direction, it would be a miracle for a normal teacher to meet such a monster student in his life, but he actually met two at the same time.

I just don’t know which one of these two little guys is more evil.

What everyone present could never imagine is that Wang Yufei's brain is still evolving all the time. No one knows how far it will eventually grow!

Even Han Xu, who traveled to this era and turned into ashes, didn't know.

"Wang Yufei, that's not right. Why are you unwilling to pay attention to other students who ask you questions, but you are so interested in this Lu Yuxin asking you a question? Also, since this question is so difficult, you are not in a hurry.

,Why were you in such a hurry after class yesterday?"
