From small town academic to chief scientist

The top student in the group next to him heard Zhou Yi saying that he wanted to eat, and he slandered in his heart.

"Eat, eat, eat. You know how to eat? How dare you choose question A? Have you never done simulation training? Obviously it is easier to write a paper if you choose question C."

For the strong, question C is most likely a multi-objective optimization model and evaluation model. The algorithms involved are almost also genetic algorithms.

For big guys, ideas come to them faster. As for whether they can be implemented, there is no telling.

Having an idea and executing it are two different things.

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

At that time, they may choose one of the best papers to implement in the company.

This is Zhou Yi's guess, otherwise why would the number of questions change from 4 to 5?

When Yang Qian heard Zhou Yi's words, she didn't hesitate. Since she had agreed to treat her to dinner, she would not go back on her word and said directly:

"Xue'er, please stay here. I'll go buy something, or order takeout? It's past six o'clock now, it's time to eat."

"Just order takeout, it doesn't have to be too much trouble."

Zhou Yi said.

After that, he continued to study the topic.

In addition to being able to complete Question A alone, you can also avoid most competitors.

Zhou Yi read the three questions. Not surprisingly, most people chose question C. Some top students from the School of Chemistry and School of Biological Sciences should have chosen question B.

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

Question A has three questions in total.

The first problem is to determine the ideal parabola 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 reflective panel.

The first question of question A may seem high-level, but it actually turns into a mathematical model, which is a problem in analytic geometry. If you are good at algebra, you can connect it with it to get a more reliable paraboloid equation.

Zhou Yi was looking at the graphs and checking information, and was thinking quickly in his mind.

With 200% comprehension ability, coupled with the mathematical foundation laid before, coupled with English literature and graphics, I already have a general direction for question one.

However, if we look at some reference papers and models in this area, we may have a deeper understanding.

Zhou Yi controlled two computers, typing on the keyboard with one hand and writing the ideas for the first question, and flipping through files and checking information with the other hand.

If one person is doing the work of three people, he must think through each step in advance.

First write a general outline of the three problems, then explore the three problems in detail, then program to solve them, and finally synthesize all the content and write a paper.

Since the mathematical models and programs are all handled by Zhou Yi, when he writes the paper later, he will be able to write smoothly and it is very easy.

[Regarding question one, based on the requirements of the question on the symmetry axis and focus of an ideal parabola, we obtained information such as the relationship between parameters in the ideal parabola and the existence domain of the parameters.

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

Time passed little by little. When Yang Qian brought the takeout 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 had already started growling.

Zhou Yi devoured it at an extremely fast speed. There was so much meat in it that Zhou Yi almost swallowed the box.

It's really delicious.

After eating, continue writing the outline of the first question and preparing materials.

After completing the first question outline and preparations, it was already ten o'clock in the evening.

At this time, almost all teams have decided which topic to do.

In the entire computer room, there were very few sounds of communication, only the sounds of typing on the keyboard or the rustling of pens and paper.

At this time, Zhou Yi said to the two girls:

"You guys go back and rest early. Come back tomorrow and leave this place to me."

"How about Yang Qianyou go back and I stay with you in case you need to do any chores?"

Xia Xue pouted and protested in a low voice.

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

Zhou Yi said calmly, rejecting Xia Xue's idea mercilessly.

Are you kidding me? If you stay until midnight and feel uncomfortable, I will have to take care of you.

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

"oh."

Seeing Zhou Yi's persistence, Xia Xue had no choice but to say this.

Only Yang Qian yawned and said tiredly:

"Zhou Yi is good, and he still cares about her. I'll leave this place to you. I'll take Xue'er back."

Here, Yang Qian did nothing, just watched Zhou Yi frantically typing on the keyboard, and used scratch paper to revise from time to time.

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

Boring as hell.

"Let's go, Xue'er."

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 about it, I searched for papers similar to my own ideas in well-known academic journals such as CNKI.

As for Baidu?

With that thing, it is better to go back to Peony Mountain and give the Peony Fairy two sticks of more expensive incense.

If you refer to the Baidu paper, you can’t even win the municipal award.

Don’t even try to catch up on any dish.

Just like using the analytic hierarchy process to solve problem C, if you don't perform secondary optimization of the mathematical model, there is no chance of winning the prize.

An hour or two passed, probably around midnight and one in the morning, and the idea for the second question had been found by Zhou Yi. The file backed up by TeX wrote,

[For question 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 graphic transformation model, and obtain a method of rotating any coordinates or functions by a fixed angle, so as to Rotate the ideal parabola equation solved in question 1 first around the y-axis (90°β), and then rotate α around the z-axis to obtain the ideal parabola equation used to observe the required celestial body.

Next, for question two, to find the optimal value of the actuator expansion and contraction, so that the reflective surface is as close to the ideal paraboloid as possible, first assume that the main cable node is moved radially to the ideal paraboloid.]

[For question 3, in order to solve the reception 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 that is 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 clarified the ideas of the three questions. Although he stayed up all night, his brain was clear and he had a very clear outline of the paper and was familiar with it.

The basic outline framework has also been constructed.

Now you only need to model the three problems separately.

Even though I was a little hungry, after thinking about it all night, the energy consumption was still huge.

The smell of instant noodles from his classmates in the computer room in the middle of the night made Zhou Yi greedy. Now that he had experienced it again for another night, how could he survive it?

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