Omnipotent Data

Chapter 369

The next day, Cheng Nuo, who had barely adjusted the time difference, rushed to Professor Fresnel's laboratory before eight o'clock in the morning.

Professor Fields is very strict with his assistant.

It's exactly like the working mode of a large company, working eight hours a day, and sometimes overtime may be done.

However, there are two days off every week that is still humane.

And the salary is two or three grades higher than the salary of an assistant professor.

Even Cheng Nuo, a newly hired newcomer, according to the contract, has a monthly salary of US$3,000. Moreover, this is not even counted as bonuses.

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

After signing the contract in Professor Fresnel's office, Cheng Nuo was officially hired.

There is no working time limit, which means that Cheng Nuo will resign whenever he wants to. However, in the face of this position, unless it is really not suitable for this bowl of rice, no one will waste this 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 inquired about this, Professor Fresnel’s assistants plus himself currently total eight.

There are currently six people in the office. I heard that another assistant has gone abroad for academic exchanges. I am afraid that it will take some time to come back.

In addition to Hull and Sylvia who had said a few words yesterday, Cheng Nuo also met four other colleagues.

All four of them are boys, but they are different in appearance, but each of them exudes the profound temperament of an academic person.

"Introduce everyone, this is Cheng from China, your new colleague!" Fresnel pushed Cheng Nuo forward.

Cheng Nuo introduced himself again.

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

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

Hull replied respectfully, "Teacher, I have probably completed two-thirds of it!"

"So..." Professor Fresnel continued to ponder. After the atmosphere was silent for more than ten seconds, Fresnel said, "Then let Cheng Nuo join your research group first, you take him."

"Okay, sir." Hull nodded and said yes, with a gentle smile on his face.

However, after listening to Professor Fresnel's arrangement, the expressions of the two boys in the assistant changed constantly, and immediately looked at each other meaningfully.

"Cheng Nuo, you and Hull will meet the matter of the project. I will go back to the office first, don't disturb me if there is nothing very important." After speaking, Professor Fresnel turned back to his compartment.

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

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

Henry and Gal are the two whose faces have changed since the professor's appointment just now.

The two looked at each other and came to Hull's desk reluctantly.

On Hull’s desk, there was simply a new Apple-brand office notebook, with some stationery and drawing tools beside it, plus a large stack of scratch paper.

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

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

Cheng Nuo pulled a chair and sat aside, and gradually got to know their project.

At present, the entire "Fresnel Research Office", er, for the time being, Cheng Nuo calls this research group with Professor Fresnel at its core.

The Fresnel Research Office has two ongoing projects.

One is a research project led by Fresnel and supported by Sylvia and three other 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.

The other project is naturally Hull's hands.

A linear modeling project on financial chaotic systems.

This project is not a research task sent by the state or school, but an outsourced project privately received by Professor Fresnel.

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

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

Therefore, every period of time, 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 a bonus.

Generally speaking, these outsourcing projects are not difficult. A research team composed of three assistants can be done in one or two months.

And this kind of good thing is also the turn of several assistants. And this time, it was Hull's turn.

This project was outsourced by a new financial company.

Cheng Nuo confidently checked the customer's requirements.

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

Very simple modeling work. In terms of difficulty, I am afraid it is only one level higher than modeling beauty.

Even if he was alone, it would not take a month to get it done.

"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 is afraid of being beaten if he speaks out.

Cheng Nuo continues to listen to Hull's modeling ideas ~ www.readwn.com ~ The so-called financial chaos system refers to a kind of randomness inherent in the financial system. And this concept is a concept put forward by U.S. economist Situ Ze in the Javier Mo economic growth equation.

System instability, bifurcation, and then use the financial system mathematical model to achieve control of this financial system.

Hull's modeling ideas are also very conventional.

First, use the method of system dynamics to establish a financial system composed of sub-blocks of production, currency, securities and labor.

Due to the irregularity of the behavior of such a system and its extreme sensitivity to initial state values ​​and parameter changes, the chaotic phenomenon mentioned above occurs.

Refining and simplifying, let x be the interest rate, the investment demand is y, and the price index is z. According to the relationship between the above three, the following equation is obtained:
