Reborn as a top student in 1990

"I look at my girlfriend, is this not okay?"

"You can't use two minds, eat first." "

I can't eat this food in my nose when I look at you. Why don't I get closer to you and feed you?"

"I hate it!"

"Hehe..."

The next day, when Jiang Chen arrived at the computer room, Zheng Shuang and the others had already arrived early.

The three of them scratched their ears and cheeks, looking very anxious, as if they were in trouble, and even Cao Huifang, who loves to find faults, was anxious: "Or, are we re-arranging?"

"Re-sorting is useless, what we did yesterday did not grasp the main contradiction at all, so the second link will be so right." Wang Jie said.

"Then make it all over again, and give up the old one. Zheng Shuang made a decision.

"Let's start looking for questions. Wang Jie's face was a little unpleasant, yesterday's mathematical model was made at his suggestion, but when it came to the second step of the model assumption stage, it could not be carried out.

This is a crucial step in building a mathematical model, grasping the essence of the problem, ignoring the secondary factors, and making necessary and reasonable simplifying assumptions about the problem according to the characteristics of the object and the purpose of the modeling. Assumptions that are not reasonable or too simple can lead to errors or useless models, and assumptions that are too detailed and try to take into account many factors of complex objects can make it impossible to build or solve models.

Their problem is in the second step, and there are too many factors to consider to proceed.

The three of them were sullen, and even Jiang Chen, an "outsider" in the room, felt the depression of the atmosphere.

It seems that the dependence of this goods is too strong, and without Mr. Liu, they have all become headless flies.

Now, Mr. Liu doesn't care about them, and it seems that he is also exercising their independent creative ability.

Jiang Chen ignored them and continued to busy himself.

The first step has been done, and today the main thing is to complete the second step.

He hung up QQ, contacted Wang Chao, and asked him to send him the information of the counseling college.

These materials are stored in the computer, which is very easy to find, and there is not much time, Wang Chao sent all the information to him.

This includes the student's grades in the past six months, and so on.

He had to sort out the numbers first, and then go through complicated calculations to get the data he needed.

Cao Huifang still waited to watch Zheng Shuang and Wang Jie do it, her role was to wait for them to calculate, she used the computer and gave them the calculated data.

At this time, she was idle, glancing at Jiang Chen from time to time.

Seeing Jiang Chen's hard work, she had a bad premonition in her heart.

Is Jiang Chen already ready?

The knowledge used in this modeling and design is in all aspects.

In addition to traditional and modern mathematical methods such as equations, drawing graphs, optimization methods, logical operations, and numerical operations, they can also use mathematical software and computer technology.

Because the solution of practical problems often requires complicated and lengthy calculations, and in many cases the operation of the system has to be simulated by computers, computer programming and mathematical software capabilities are also very important.

Listening to the sound of Jiang Chen tapping on the keyboard quickly, Cao Huifang couldn't help but feel nervous, the bad feeling became heavier and heavier, but she couldn't figure it out, she really couldn't figure it out.

Jiang Chen, he is a high school student! How can he have such a high level?

After completing a procedure, Jiang Chenjue's legs were a little numb, and he understood that this was because he had been sitting for too long, so he hurriedly stood up and walked to the window to move.

There is a row of poplar trees planted outside the computer room, the leaves have turned yellow, a wind blows, and it falls with the wind, and the yard is golden yellow, which has a sense of killing with a strong wind sweeping the fallen leaves.

Jiang Chen leaned against the window and pinched his wrist, and the feeling of soreness in his hands eased a lot.

In order to liberate his legs, he went to the bathroom, and when he came back after solving his physiology, the soreness and numbness in his legs disappeared.

Sit down at your computer and get back to work.

During lunch, Cao Huifang shouted to Jiang Chen for the first time: "It's time to eat!"

Jiang Chen was a little confused, this thing has changed?

The four of them rushed to the cafeteria together, Jiang Chen finished cooking, and before he reached the table, Jiang Qinqin had already sat down on the table he chose.

"On purpose?" Jiang Chen didn't move to the other table, and sat down with the lunch box.

"This is not your family, can't I sit?" Jiang Qinqin asked with an innocent face.

Jiang Chen found that Jiang Qinqin's ability to find fault was really first-class, and he was willing to bow down to this.

Immerse yourself in eating, regardless of her.

Cao Huifang and the three of them were sitting at the next table, and at this time, the eyes of the three of them were a little ambiguous.

"What do you see, haven't you seen your boyfriend and girlfriend eating together?" Jiang Qinqin glared at them unceremoniously, and muttered: "It's rare and weird, they're all seniors, are they all singles?"

Zheng Shuang and Wang Jie were embarrassed and embarrassed, and hurriedly lowered their heads to eat to hide their embarrassment.

Cao Huifang is not a good stubble, and immediately went back: "How do you know that we look at you, it means that you also look at us." If your eyes grow on someone else's body, can you still cover other people's eyes, don't let you look at them, and go home and hide. "

Who are you talking about?" Jiang Qinqin stood up diligently, and he was about to move to Cao Huifang's side.

Jiang Chen hurriedly pulled her: "If you have something to say, you can say it." "

Who is she?" Jiang Qinqin asked, pointing at Cao Huifang.

"Senior sister, in a class, and..." Before Jiang Chen could finish speaking, he was interrupted by Jiang Qinqin: "And what, she didn't have the skin and no face to stick on you

?" Jiang Chen's face sank: "What is this called?"

"Jiang Chen," Cao Huifang also kicked away the chair suddenly, pointed at Jiang Qinqin and asked: "She is really your girlfriend?"

"Don't get me wrong..." also didn't give him a chance to finish speaking, Cao Huifang had already scolded: "I'll just say, how can you fall in love with this kind of goods, you look like a dog, and you don't have any education at all." Jiang Chen, I advise you to keep your eyes open, don't be fooled by some ugly monsters. "

Smack!" Cao Huifang just said, where did she expect Jiang Qinqin to suddenly make a move, covering her hot cheeks, she pounced and tore Jiang Qinqin together.

Jiang Chen was busy pulling up a frame for them, Zheng Shuang and Wang Jie looked at each other, and seemed a little helpless in the face of the emergency.

"How can this be?"

"Yes, how can they fight, and I don't see much conflict." "

Neither of them quite understood the reason for the fight for no reason.

The two of them were like crazy, neither of them would give up, and they both wanted to scratch each other's faces.

Jiang Chen was one head and two big, he couldn't resist, and hurriedly shouted Zheng Shuang and Wang Jie: "Hurry up and

pull Cao Huifang!" The two of them were busy pulling Cao Huifang, but it still took a lot of effort to pull them away.

It didn't matter if they pulled it away, both of them were unkempt, and their hair was scattered, like female ghosts.

The people in the cafeteria all looked at this side, and Jiang Chen almost couldn't hold back his laughter.

Even Zheng Shuang and Wang Jie couldn't help laughing.
