Omnipotent Data

Chapter 369

The next day, Cheng Nuo, who barely adjusted to the jet lag, arrived at Professor Fresnel's laboratory before 8:00 am.

Professor Fields is very strict with his assistants.

It is completely like the working mode of a large company, with a fixed work of eight hours a day, and there may be overtime from time to time.

However, it is still humane and has two days off every week.

And the salary is two or three grades higher than that of the general professor's assistant.

Even Cheng Nuo, a newcomer who has just joined the company, has a monthly salary of 3,000 US dollars according to the contract. And, that's not counting bonuses or anything like that.

Instead of wearing the company's professional suit, Cheng Nuo walked into the office in simple casual clothes.

After signing the contract in Professor Fresnel's office, Cheng Nuo officially joined the job.

There was no time limit for working, which meant that Cheng Nuo could resign whenever he wanted. However, in the face of this position, unless it is really not suitable for this bowl of rice, no one will waste the time with Professor Fresnel.

Leading Cheng Nuo out of the cubicle, Professor Fresnel clapped his hands to attract the attention of the other six students in the office.

Cheng Nuo had inquired about this, and there were eight of Professor Fresnel's assistants and himself.

There are six people in the office now, and I heard that one of his assistants has gone abroad for academic exchange, and I am afraid he will not come back for a while.

Apart from Hull and Xi Weier who had said a few words yesterday, Cheng Nuo also met four other colleagues.

All four of them are boys, but they have different appearances, but each of them exudes the profound temperament of academic people.

"Let me introduce to everyone, this is Cheng from Huaguo, your new colleague!" Fresnel pushed Cheng Nuo forward.

Cheng Nuo introduced himself again.

"Okay, I'll assign Cheng Nuo's tasks now." Fresnel pondered for a few seconds, as if he hadn't made a decision yet.

He turned his head and asked Hull, "Hull, how is the progress of your project team?"

Hull respectfully replied,

"Teacher, it's about two-thirds done!"

"Is that so..." Professor Fresnel continued to ponder. After more than ten seconds of silence, Fresnel said, "Let Cheng Nuo join your research group first, and take him with you."

"Okay, teacher." Hull nodded and said yes, with that faint and warm smile on his face all the time.

However, after listening to Professor Fresnel's arrangement, the expressions of the two boys among the assistants kept changing, and they looked at each other meaningfully.

"Cheng Nuo, talk to Hull about the project. I'm going back to the office first. Don't disturb me if there is nothing important." After speaking, Professor Fresnel turned and went back to his cubicle.

Outside the office, several doctoral assistants breathed a sigh of relief.

Hull smiled faintly at Cheng Nuo, "Cheng, let's discuss the project. By the way, Henry and Gal can come too."

Henry and Gal were the two whose faces changed after the appointment of the professor just now.

The two looked at each other, and came to Hull's desk with a little reluctance.

On Hull's desk, there is only the latest Apple brand office notebook, along with some stationery and drawing tools, and a large stack of draft paper.

For creatures like mathematicians, scratch paper is as important as toilet paper when going to the bathroom!

Hull opened a document on the computer and explained to Cheng Nuo the project the three of them were currently working on.

Cheng Nuo pulled up a chair and sat aside, gradually understanding their project.

Currently, the entire "Fresnel Research Office", er, Cheng Nuo called this research group with Professor Fresnel as its core for the time being.

The Fresnel Research Office has two ongoing projects.

One is a research project led by Fresnel, with Xi Weier and three other assistants as assistants. It was a project jointly approved by the Cambridge Research Institute and the Massachusetts Institute of Technology, and the research content was in the field of geometry.

Another project, of course, is this one in the hands of Hull.

A linear modeling project on financial chaotic systems.

This project is not a research task sent by the country or the school, but an outsourcing project privately accepted by Professor Fresnel.

The so-called outsourcing project means that some companies do not have the strength to carry out the project, so they hand over the project to others and just pay for it.

And Professor Fresnel is a big brand here, I am afraid that there are not a few companies that are willing to entrust him with outsourcing projects.

Therefore, every once in a while, Professor Fresnel will take on several cost-effective outsourcing projects and hand them over to several of his assistants. Part of the outsourcing funds will also be given to the assistants as bonuses.

Generally speaking, these outsourcing projects are not difficult. A research team composed of three assistants can finish it in a month or two.

And this kind of good thing is also done by several assistants in turn. But this time, it was Hull's turn.

This project was outsourced by a newly established financial company.

Cheng Nuo checked the customer's request confidently.

To put it simply, customers hope that they can create a model for the financial chaotic system, which includes deposit interest rates, linear control of investment demand, and comprehensive financial linear control.

Very simple modeling job. In terms of difficulty, I'm afraid it's only a level higher than the modeling competition.

Even if he is alone, it can be done in less than a month.

"How long have you been working on this subject?" Cheng Nuo asked.

"Twenty-five days!" Henry replied proudly.

Twenty-five days, two-thirds of the progress, or three people?

Cheng Nuo remained silent and did not speak.

Because he was afraid that he would be beaten if he spoke up.

Cheng Nuo continued to listen to Hull's modeling ideas.

The so-called financial chaotic system refers to a kind of randomness inherent in the financial system itself. And this concept is a concept proposed by American economist Situ Ze in the Havelmo economic growth equation.

The system is unstable and bifurcated, and then with the help of the financial system mathematical model, the control of this financial system is realized.

The modeling ideas of the three of Hull are also very conventional.

Firstly, a financial system composed of production sub-block, currency, securities sub-block and labor sub-block is established by using the method of system dynamics.

Due to the irregular behavior of such a system and its extreme sensitivity to the initial value of the state and parameter changes, the above-mentioned chaotic phenomenon is produced.

Then refine and simplify, let x be the interest rate, investment demand be y, and price index be z. According to the relationship between the above three, the following equation can be obtained:
