From small town scholar to chief scientist

Chapter 15

The Xueba in the group next to him heard Zhou Yi say that he wanted to eat, and he slandered him in his heart.
"Eat, eat, eat, you know how to eat? How dare you choose question A? Haven't you done simulation training? Obviously, choosing question C is easier to write a paper."

For question C, for the strong, the high probability is the multi-objective optimization model and evaluation model, and the algorithms involved are almost genetic algorithms.

For the big guys, the idea comes faster, as for whether it can be done, there are two opinions.

Having an idea and making it out are two different things.

This kind of question C, at first glance, is that a large and medium-sized company has spent money and paid sponsorship fees, and asked the organizer to help the elite college students across the country to help solve it.

At that time, they may choose the best paper to implement in the company.

This is Zhouyi's guess, otherwise why change from the previous 4 questions to 5 questions.

Yang Qian didn't hesitate when she heard Zhou Yi's words. Since she agreed to invite dinner, she would not regret it, and said directly:

"Xue'er, you can stay here, I'll go shopping, or order a takeaway? It's past six o'clock, and it's time to eat."

"Order a takeaway, it doesn't have to be too much trouble."

Zhou Yi said.

After speaking, continue to study the topic.

Choosing question A, in addition to being able to complete it by one person, can also avoid most of the competitors.

After reading the three questions in Zhou Yi, it was no surprise that most of them chose question C, and some top students from the School of Chemistry and Biological Sciences should choose question B.

As for question A, only those who are good at physics or mathematics will choose it.

There are three questions in question A.
The first problem is to determine the ideal paraboloid when the celestial body S to be observed is located directly above the reference sphere, that is, α = 0°, β = 90°, taking into account the adjustment factors of the reflector.

The first sub-question of question A looks tall, but it is actually transformed into a mathematical model, which is a problem in analytic geometry. If you are good at algebra, you can also connect with it to get a more reliable parabolic equation.

Zhou Yi was looking at the graph while looking up information, and he was also thinking quickly in his mind.
With a 200% comprehension ability, coupled with the mathematical foundation laid before, coupled with English literature and graphics, there is already a general direction for question [-].

However, if you look at some reference papers and models in this regard, you may have a deeper understanding.
Zhou Yi controls the two computers, typing on the keyboard with one hand, writing the train of thought for the first question, and flipping through the documents and checking the information with the other hand.

When one person does the work of three people, one must think about the steps of each part in advance.

First write a general outline of the three questions, and then explore the three questions in detail, followed by programming to solve them, and finally write a paper by synthesizing all the content.

Since the mathematical models and programs are all operated by Zhou Yi, it is very easy to write a thesis later.

[About question [-], according to the requirements of the question on the symmetry axis and focus of the ideal paraboloid, we have obtained information such as the relationship between parameters in the ideal paraboloid, the existence domain of the parameters, etc.

Then, by considering the spatial characteristics of the actuator installation, it is found that the method of dividing the central angle of a certain area equally can be used to design a model that can simulate the distribution of the actuator and estimate the expansion and contraction of the actuator]

Time passed, and when Yang Qian brought the food back to the computer room, she didn't notice it.
It wasn't until Xia Xue reminded him softly that Zhou Yi felt that a long time had passed, and his stomach was already rumbling.

Zhou Yi gobbled it up extremely fast. There was so much meat in it that Zhou Yi almost ate the box.

is really delicious.

After eating, continue to write the outline of the first question and prepare materials.

After completing the first question outline and preparations, it was already ten o'clock in the evening.
At this time, almost the teams have already decided which topic to do.

In the entire computer room, there are very few voices of communication, but only the sound of typing on the keyboard or the rustling of pens and paper.

At this time, Zhou Yi said to the second daughter:

"Go back and rest early, come back tomorrow, and leave this place to me."

"How about Yang Qianyi go back, I will stay with you, what if I need to do chores?"

Xia Xue pouted and protested softly.

"Go back, you will affect me here, just deliver the food on time tomorrow."

Zhou Yi said lightly, and mercilessly rejected Xia Xue's idea.

What a joke, if you stay up until midnight and feel uncomfortable, don't you have me to take care of you.

Only when you are all gone can I devote myself fully to it.

"Oh."

Seeing Zhou Yi's insistence, Xia Xue had no choice but to say so.

Only Yang Qian yawned and said wearily:

"Zhouyi is not bad, I still feel sorry for Xiangxiang and Xiyu, I will leave it to you here, and I will take Xue'er back."

Here, Yang Qian didn't do anything, just watched Zhou Yi typing on the keyboard frantically, and from time to time, he used draft paper to revise and revise.

The two of them could only watch and couldn't help at all.

Boring as hell.

"Let's go, Cher."

Yang Qian took Xia Xue's hand and left directly.

After the two left, Zhou Yi began to think about the second question,

While thinking, I searched for papers similar to my own in well-known academic journals such as HowNet.

As for Baidu?

With that thing, it's better to go back to Peony Mountain and offer two sticks of more expensive incense to Peony Fairy.

Refer to Baidu papers, don't even think about winning the city award.

Don't try to catch up with any dish.

Just like using the analytic hierarchy process for problem C, if you don't optimize the mathematical model twice, you don't even want to win the prize.

One or two hours passed, around one o'clock in the morning at midnight, the idea of ​​the second question has also been found by Zhou Yi, written in the file backed up by TeX,
[Aiming at problem 2, first, in order to solve the ideal paraboloid when the observed celestial body is located at the azimuth angle α=36.795", β=78.169", first establish a rotation matrix and a graphical transformation model, and obtain a method to rotate any coordinate or function at a fixed angle, so that Rotate the ideal paraboloid equation obtained from the solution of problem 90 first around the y-axis ([-]°β), and then rotate α around the z-axis to obtain the ideal paraboloid equation for observing the required celestial body,

Next, for the second problem, to solve the optimal value of the expansion and contraction of the actuator, so that the reflective surface is as close as possible to the ideal paraboloid, it is assumed that the main cable node is moved radially to the ideal paraboloid.]

[For problem 3, in order to solve the receiving ratio of the adjusted feed cabin, each reflection unit needs to be processed separately.First define the ratio of the electromagnetic wave signal reflected by a single reflective panel absorbed by the feed cabin as the unit absorption ratio, and then calculate the ratio of the reflected signal amount of each reflective panel to the total reflected signal amount as the weight of its unit absorption ratio]

In one night, Zhou Yi almost sorted out all the ideas of the three questions. Although he stayed up all night, his brain was clear, and he was very clear about the outline of the thesis, and he was familiar with it.

The basic outline framework has also been constructed,

Now it is only necessary to model the three problems separately.

It's just that I'm a little hungry, and after thinking about it all night, the energy consumption is still very huge.

The smell of instant noodles from classmates in the computer room in the middle of the night made Zhou Yi greedy. Now that he has experienced another night, how can he stand it?

I can only hope that Xia Xue and Yang Qian will bring breakfast soon.
