Chapter 369

The next day, Cheng Nuo, who had barely adjusted to the jet lag, arrived at Professor Fresnel's lab before 8 o'clock in the morning.

Professor Fields was very strict with his assistants.

It's exactly like the working model of a large company, with a fixed eight-hour day and the possibility of overtime from time to time.

However, it is quite humane, and there are two days off per week.

And in terms of salary, it is two or three grades higher than the salary of the assistant of the average professor.

Even Cheng Nuo, a newcomer who has just joined the company, has a salary of $3,000 per month according to the contract. And that's not even counting things like bonuses.

There is no need to wear a professional suit from the company, Cheng Nuo walked into the office in a simple casual suit.

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

There is no limit to the time limit for work, which means that Cheng Nuo can resign whenever he wants. It's just that 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.

Led Cheng Nuo out of the cubicle, Professor Fresnel clapped his hands, attracting the attention of the other six students in the office.

Cheng Nuo inquired about this, and Professor Fresnel's assistants and himself currently have a total of eight.

Now there are six people in the office, and I heard that there is also an assistant who has gone abroad for academic exchanges, and I am afraid that it will be some time before he returns.

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

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

"Let me introduce you, 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 task now. Fresnel pondered for a few seconds, as if he hadn't made up his mind.

He turned to Hull and asked, "Hull, how's your project team doing?"

Hull replied respectfully, "Teacher, you're probably two-thirds of the way through!"

"That's right......" Professor Fresnel continued to mutter. After the atmosphere was silent for more than ten seconds, Fresnel spoke, "Then let Cheng Nuo enter your research group first, and you can take him with you." ”

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

It's just that, after listening to Professor Fresnel's arrangement, the faces of the two boys in the assistant kept changing, and they immediately glanced at each other meaningfully.

"Cheng Nuo, you and Hull will talk about the project. I'm going back to the office first, there's nothing very important not to bother me. With that, Professor Fresnel turned back to his compartment.

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 are coming, too. ”

Henry and Gal were the two whose faces had changed just now after the professor's appointment.

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

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

For a creature like a mathematician, scratch paper is as important as toilet paper when you go to the toilet!

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

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

At the moment, the entire "Fresnel Research Office", well, Cheng Nuo tentatively calls this research group with Professor Fresnel at its core.

Fresnel Research Office, there are two ongoing projects.

One is a research project led by Fresnel, supported by Sivele and three other assistants. It was a joint project approved by the Cambridge Institute and the Massachusetts Institute of Technology in the field of geometry.

And the other project, naturally, is this one in Hull's hands.

A linear modeling project on financial chaotic systems.

This project is not a research assignment sent by the state or the university, but an outsourcing project that Professor Fresnel has privately undertaken.

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 to do it, and they only have to pay for it.

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

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 to do, and part of the outsourcing funds will also be given to the assistants as bonuses.

Generally speaking, these outsourcing projects will not be difficult. A research team of three assistants can do it in a month or two.

And this kind of good thing is also a few assistants in turn. And this time, it was the turn of the three Hulls.

The project was outsourced by a newly established financial company.

Cheng Nuo confidently checked the customer's requirements.

To put it simply, the client wants them to create a model for the financial chaos system, which includes linear control of deposit interest rates, investment demand, and financial comprehensive linear control.

Very simple modeling work. In terms of difficulty, I'm afraid it's only a notch higher than that of modeling Meisai.

Even if he is allowed to do it alone, it will not take him a month to do it.

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

"Twenty-five days!" replied Henry, with a proud look on his face.

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 out.

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

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

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

The Hull trio's approach to modeling is also very conventional.

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

Such a system produces the chaotic phenomena mentioned above due to the irregularity of its behavior and its extreme sensitivity to changes in the initial value of the state and parameters.

Then refine and simplify, 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:
