Academic tyrant: I have become a prodigy since I was able to pursue my academic career with peace of

Chapter 32 Mathematical Modeling Competition (please support, second update)

In the classroom, Qiunan was flipping through the advanced mathematics in his hand.

The deputy leader of the mathematics group sat next to Chen Fan and said,"Are there really no students like you?"

Chen Fan said,"The mathematical modeling competition in groups of three includes a defense component. , the production of ppt tables, and the core of basic mathematical modeling. It is considered an advanced practical application paper. With so many links, who can do it?"

In fact, there are basically two mathematical modeling papers every year. The top student brings a network dog, the so-called network dog, who uses his network to get in. He is responsible for the whole process of paddling and other things. When he gets the prize, he only needs his name to appear on it.

Mathematical modeling is linked to actual work. You need to know that winning the IBM Olympiad competition will not add any extra points to your work resume. But if you win the prize in the mathematical modeling competition, then it is obvious that , countless companies will rush to get you

"So how do you plan to choose people? There are not many students in the school anymore. After the summer vacation, the modeling competition will begin. By then, there will not be much preparation time."

"Well, it's nothing, no rush, there's no shortage of topics, what's missing is people, I just don't like people dogs."

Sigh.

The deputy team leader sighed helplessly. There's really no way to talk about this matter.

In the mathematical modeling competition back then, Chen Fan was in charge of everything, and the other two people paddled the whole process. Because of this matter Later, Chen Fan was very angry. As a result, the entire mathematics team collectively spoke up for Chen Fan and canceled the graduation grades of those two children.

However, there has always been such a thing as a network dog.

"The basic competition is actually very simple. This year is different from previous years. This year, you only need to make the topic and then submit it.

Chen Fan said:"That's actually very simple." It would be great if all students had the right to participate"

"Can you come over and see it? So many papers?"

"That's my thing. There aren't as many people here at Peking University who like mathematics as you think, or do you think it's a lot of work?"

"Why are there thousands of people? Chen Fan said:"

I will give you a small program later. I coded it myself for fun. It is specially used to check for plagiarism. You can check it according to this standard. If the paper's plagiarism check exceeds 30%, all of them will be screened. Just drop it, that's basically it"

"And this good thing? But it is indeed quite uncomfortable for students. By the way, Chen Fan, do you plan to let these students study mathematical modeling topics on their own?"

"Well, research it yourself. It doesn’t take long to write a model. One day is enough. If you understand it, you will naturally send it to me. If you don’t understand it, even if you send it to me, it will be screened out by the machine."

The deputy team leader nodded, but seriously, he began to sympathize with this generation of college students. From the current situation, Chen Fan seems to be planning to use some power.

He is not worried about the leader accepting gifts, but worried about people like Chen Fan , the kind of person who is serious and never gets into anything.

There are scumbags and overachievers in any school, but there are relatively few at Peking University and Tsinghua University.

After the news came out, the entire mathematics department was like a fight. As good as chicken blood

"Is Chen Fan leading the team in this year’s mathematical modeling competition?"

"My God, this great team leader will definitely be stable this year."

"Touch the gods up close."

The Department of Mathematics is very uneasy, but other majors are much calmer. After all, Peking University is great in academics, but most of Peking University's admissions are focused on liberal arts.

It is rare to find talents in mathematics.

Of course, no one is interested in mathematics. I'm particularly interested. I know that Chen Fan and his team won the award. How awesome. He is very awesome anyway.

And I heard that Chen Fan solved the world's difficult problem. What next

? Would the world become a better place, or would life become more interesting? Obviously, neither would work.

Therefore, academia was destined to be a game for small circles.

At night, Chen Fan connected Nuwa on his watch to the computer.

"Filter"

"OK"

As expected, a total of 3,250 basic modeling papers were received.

However, with 30% of the duplication checked, there were only a few hundred papers left.

In fact, it is easy to understand. Mathematical construction Modeling is something that graduate students only start to learn. The basic writing methods are very vague. I have seen the templates and solved the problems. In fact, it is not the core, because if it is just arithmetic, the mathematical modeling will not highlight its height.

The most interesting thing is naturally the defense session in mathematical modeling.

Of course, these must be entered into the finals. Chen Fan only needs to read a summary of each one, but there is one core thing. Modeling attracted Chen Fan

"Operation and management of pig farms

A certain pig farm can raise up to 10,000 pigs, and the pig farm uses its own breeding pigs for breeding.

The general process of raising pigs is: after sows are bred, they will be pregnant for about 114 days and give birth to suckling pigs.

After the lactation period, the suckling pigs will become piglets.

Part of the piglets will be selected as breeding pigs (the proportion of boars and sows varies depending on the breeding method), and when they grow up, they will take on the breeding tasks of pig farms; sometimes a part of the piglets will be sold as piglets to control the scale of breeding; Most of the piglets are castrated and then grown into pigs for slaughter (see Figure 1).

The reproductive period of sows is generally 3 to 5 years, and boars and sows that have lost their fertility will be disposed of harmlessly.

Breeding pigs and meat pigs consume feed every day, but the cost of feed for breeding pigs is higher.

Breeding farms optimize their business strategies by determining the number of reserved seeds, breeding time, stock size, etc.

based on market conditions to increase profitability.

Please collect relevant data and establish a mathematical model to answer the following questions:……"

This question seems to be from 2014. It seems to be a modeling competition that year. There are four options abcd, choose one to complete.

What about the old question, the new algorithm?

Looking down, Chen Fan nodded happily. Sure enough, it was still powerful. ps: Please support me, thank you all.
