Reborn as a top student in 1990

Liu Haoming answered Jiang Chen's questions one by one, and his questions always pointed out the key points to the point. Xueba deserves to be a Xueba, and Xueba and his students have teamed up, and this model will definitely be different when designed.

Professor Liu couldn't help but sigh, he had led a total of three mathematical modeling competitions, Zheng Shuang and the three of them were the best students in this area he had ever seen, but they were still inferior to Jiang Chen, who was the most talented student he had ever seen.

If Jiang Chen is the main designer of the modeling design, it is estimated that he will be able to win a prize in the competition.

However, can his students get along with him amicably?

Although after yesterday's test, the attitude of the three of them towards Jiang Chen has changed, but they may not be able to get along well.

It's a headache for him.

"Teacher, I don't want to rob my brothers and sisters of the credit, I'd better start anew. I hope you can give me a place in the competition.

After watching the simulation, Jiang Chen said his thoughts straight to the point.

Liu Haoming was stunned for a moment, and then swept his gaze to Zheng Shuang and the others, and his heart was clear.

Since Wang Huifang came to him yesterday, he already knew that they had an unpleasant situation, and it seemed that the three of them had gone too far, forcing Jiang Chen to start anew.

Zheng Shuang and the three of them looked at each other, knowing that it was impossible to get Jiang Chen to join their team.

I was also very happy.

This is not a design work, Jiang Chen has already begun to be proud, dragging 2580,000 yuan, as if the trophy of the national modeling competition was reserved for him.

Arrogant!

As everyone knows, he can design something alone.

Although he got a perfect score in yesterday's test and knows a little about modeling and design, he may not know what if it is really a competition.

"It's okay if you want to set up your own door, I'll give you this opportunity, but what can only be done by three people, can you do it alone?" Although Jiang Chen has the ability, he has no experience in this aspect. What he meant was that the four of them worked together on a single piece. However, this is no longer possible.

"I'll give it a try," Jiang Chen said very tactfully: "It's better for four people to win one award in a partnership, it's better to win two awards separately."

"Speaking big, it's like you will definitely win the prize, Jiang Chen, the modeling competition is not your Olympiad competition, and it is not so easy to get ranked. Cao Huifang finally couldn't help it and poured cold water on Jiang Chen.

"Participating in the competition is just to get a ranking, otherwise, what am I doing with all this effort?" Jiang Chen unceremoniously replied.

"Then you will definitely win the award?" Cao Huifang was a little disdainful of Jiang Chen's self-confidence.

"At least I'm confident.

"That's because you're too conceited, you haven't even skimmed the eight characters, and it's too early to say that you'll win the prize."

"At the very least, I dare to think that I am not like some people, with the attitude of trying it out, and I dare not have any confidence at all. "

You..." Cao Huifang was finally defeated.

"Newborn calves are not afraid of tigers, Jiang Chen, I am optimistic about you!" Liu Haoming looked at the two of them and squinted slightly: "It's a good thing to have confidence, the three of you have to learn from Jiang Chen." "

Teacher?" Cao Huifang twisted her body, like a child, and looked at Liu Haoming unwillingly: "He's just talking big."

Professor Liu looked at her with a smile, and was as good as ever about this female student: "Shouldn't we be hopeful before the results come out? Don't be overly optimistic, but don't be pessimistic either." Well, since you want to divide into two groups, then prepare your own.

After Liu Haoming finished speaking, he went to the office, leaving them to study their own design.

There were dozens of computers in the computer room, and Jiang Chen deliberately found one that was a little farther away from the three of them, so as not to be embarrassed.

Standing on their own, not only did they design their own, they also became competitors.

Both groups understand this.

"Cut, Jiang Chen, if we meet in the competition, our work will definitely win. Zheng Shuang and Wang Jie had already started to operate the computer, Cao Huifang had nothing to do, looked at Jiang Chen, who was far away from them, and turned on the mode of ridiculing people.

Now that they are competitors, she looks down on Jiang Chen even more unpleasantly.

Jiang Chen didn't raise his head: "It's too early to say this, I'll tell you, the eight characters haven't been skimmed yet, who knows who is better." "

You..." Cao Huifang felt that Jiang Chen could always block her with her words, and she couldn't get angry: "To tell you the truth, we won the third place in the competition last year, and this year we worked hard, and it was not a problem at all to go to the next level." What about you? You have no experience, you don't have good design, you don't have in-depth study in this area, and you just rely on your talent in this area, you are just a beginner compared to us, and you are 108,000 miles behind us, what can you fight with us?"

Jiang Chen was a little speechless.

This thing really has nothing to do except squeeze him?

Also, look at Zheng Shuang and Wang Jie, who are busy with their work, they are working hard, she is squeezing people here, and I don't know why Liu Haoming is so optimistic about him as a female student?

Quarreling with this kind of person, he can't afford to delay that time.

A series of numbers appeared on the computer screen, and Jiang Chen hurriedly concentrated. What Liu Haoming just said is very clear, but that is only a case of modeling.

What he has to do is to design his own modeling program and participate in the competition.

During this time in the Olympiad group, Jiang Chen has had in-depth study of Olympiad knowledge, and he has read a lot of books on this subject.

It is already handy to do data estimation and other aspects.

The first step in modeling is to ask questions, i.e., to express the actual problems encountered in appropriate mathematical language. In general, the first task is to define the terms. Whether it is the variables involved in the actual problem, or the units of these variables, and the relevant assumptions, they should be expressed in terms of equations or inequalities. Jiang Chen felt that it was not difficult to do this.

On this basis, the practical problem is paraphrased in mathematical language and constitutes a complete problem. The distinction between variables and parameters is important and needs to be distinguished. Once you've completed the first step, you can get a list of variables, assumptions, and goals. The list shows clearly the variables that the problem contains, the relation derived from the question, and the goal. The main basis for determining whether the first step is successful is whether the goal can be converted into a function of a variable. This is crucial.

Jiang Chen began to make the first step.

Just typed out a line of data, and found that Cao Huifang was staring at herself, and the other party had some contemptuous eyes, which made people very unhappy.

"Something?" Jiang Chen asked with a smile.

This thing was always distracting, and he hated her a little.

Cao Huifang pouted: "We have completed the first step, what about you?"

In the face of this provocation, Jiang Chen couldn't help laughing: "What do you care? "
