After finishing the materials, Mr. Liu announced the disbandment and said that if he was not busy with the review, he could go back today to take a look at the materials.

Tomorrow we will gather in the school computer room to start the first run-in training.

After Mr. Liu announced his disbandment, Lu Zhou went to the library with his computer bag on his back and continued to rush the manuscript frantically.

As for the information in the USB flash drive, he didn't even have time to look at it.

After all, for him, compared to the tasks of the school, the tasks of the system are more prioritized.

In addition to writing papers, Lu Zhou also occasionally found time to teach Chen Yushan a few advanced math questions.

To be honest, this guy's math foundation is not generally poor, and a lot of things have been completely returned to the teacher, and I don't know how she got a score of 85 in high math (self-proclaimed) in her freshman year.

"Don't you study math in business school?" Completely defeated by a problem of finding the limit of a function, Lu Zhou rolled his eyes and wrote out the solution on the scratch paper, and complained mercilessly, "The teacher has definitely talked about this problem as an example problem in class." ”

Chen Yushan blushed, unconvinced, and had to argue stubbornly: "I studied economic management, not accounting." With so many things to memorize, how can I have time to study mathematics? ”

"I remember that the Department of Economics and Management also wanted to study accounting and statistics......

"Shut up, I'll have lunch."

Lu Zhou resolutely shut up, and said in his heart, don't be polite, just ask if you have questions, don't hold back.

It's best to have dinner by the way......

If others invite guests to dinner, Lu Zhou will feel somewhat indebted, even if his economic conditions are average, he will find an opportunity to invite him back.

But if Chen Yushan wants to invite herself to dinner......

He was unceremonious.

Why should you pay back the food that you have with your ability?

Help you go through the advanced math knowledge points from beginning to end, and I don't charge you for make-up classes, it's not too much to skip one or two meals, right?

After the library closed, Lu Zhou returned to his dormitory and was busy for a while, finally finishing his first math paper.

The value coefficient of this paper should be the highest among the ten papers, and the systematic evaluation is 30 points. Considering that some of the conclusions of this paper are supplementary to his previous paper, Lu Zhou plans to try to submit it again to the journal Theoretical and Applied Mathematics Communications.

As for the remaining nine computer papers, his goal is "Modern Communication and Geo-Information Technology".

As a non-core journal, this domestic journal is very rare in that it does not charge review fees and layout fees, and it does not pay much attention to whether the contributor has financial support, and there is even a manuscript fee of 150 yuan. And those demons who only stare at the money in the pockets of scientific researchers. Yan Cheap. Compared with the goods, this journal is simply a clear stream in the "general journal world"!

9 papers, you can get 1350 yuan!

After uploading the math paper, it was already two o'clock in the morning.

Seeing that it was not early, Lu Zhou closed his laptop, yawned and lay on the bed, listening to the snoring of his roommates one after another, and slowly fell asleep.

……

The next day, Lu Zhou learned to be obedient, didn't come too early, pinched a little, and stepped on Mr. Liu's hind feet into the computer room. As a result, after entering the computer room, he realized that he was not the latest to arrive. When he and the teacher came in, only Xiaodong was sitting alone in the computer room.

"Early."

Lu Zhou said hello with a smile as always, thinking that this arrogant student would ignore him, but he didn't expect him to unexpectedly snort.

"Early."

Although there is only one word, it can be regarded as a big breakthrough.

Lu Zhou sighed with relief in his heart.

To be honest, he is not worried about the strength of his team at all, the only thing he is worried about is the compatibility between the players. I believe that not only is I having a headache, but Mr. Liu must also have a headache.

If it can be used as a lubricant in the team, it doesn't seem like a bad thing to bring this pit goods with classmate Lin?

Probably.

At this moment when he was deserting, classmate Lin was finally late, but this time it was okay, she was only fifteen minutes late, which was not too long.

Professor Liu Xiangping didn't say anything about her as always, just smiled faintly, motioned for her to find a place to sit down, and then started today's class.

According to the training process, today is a run-in training to cultivate tacit cooperation between team members.

In order not to delay more time, the problem setting is not very difficult, and it can be solved on the spot.

Mr. Liu gave a string of fictitious telecom user data, and formulated more than 20 projects, which require that users be classified into consumption habits through mathematical modeling, and products designed for different user groups.

Because the data is all fictitious, the appendix to the question does not give the source of the data, only an excel sheet.

The knowledge required is more statistical than computational, and even has a lot of knowledge in economics and product management. Compared to yesterday's appetizer, the difficulty of this question has undoubtedly increased a lot.

The problem of simple mathematical formulas for this kind of practical application is not that they are useless, but that the difficulty of this kind of problem itself is not in mathematics, but in how to transform such problems into mathematical problems.

However, fortunately, the problem itself is not very complicated, at most it involves too wide a range of knowledge, Lu Zhou conceived for about half an hour, first through statistical knowledge to classify the user group, and finally used the matrix algorithm to solve the two problems in the question stem.

took a few pieces of scratch paper and went to Wang Xiaodong's side, Lu Zhou put the paper on his computer desk, "The modeling is done, I have already sent the email to your mailbox, and the other part of the process I calculated with a pen, all written on paper, and the process of sorting out the equation and entering it into the computer is no problem for you, right?" ”

Wang Xiaodong nodded and said succinctly: "No problem." ”

Xueba deserves to be a Xueba, and the efficiency of the two Xueba joining forces is really extraordinary.

Lu Zhou quickly completed the mathematical modeling work, and Wang Xiaodong also quickly completed the programming with the computer in the computer room, which added up to less than two hours. What was expected to take a day's work was completed in just that little time.

After examining the results of Lu Zhou and Wang Xiaodong respectively, Professor Liu couldn't help but sigh that he had led a total of five mathematical modeling competitions, and the two of them were the most talented students he had ever seen.

Lu Zhou smiled and gladly accepted the teacher's praise. As for Wang Xiaodong, he was expressionless as always, but it could be seen from the corners of his hooked mouth that he was still quite proud in his heart.

The first run-in training went well.

However, the only problem is with Lin Yuxiang......

Although this guy has written a lot of student union work reports, he has never written a paper at all, and even the format requirements of the paper are whiteness on the spot, and he has not made any progress after sitting for almost half an hour.

Wang Xiaodong was embarrassed, after all, he patted his chest and assured the department leader that Lin Yuxiang would definitely be able to handle this task, but it was not yet the game, and she dropped the chain during the first round of run-in training.

Although Lu Zhou smiled slightly, he felt a burst of hemp selling in his heart.

You said that you are engaged in student work, so you should do your student work well, and in the future, you should join the party and enter the civil service examination, and the civil service examination should be examined, and the future is very good, so you have to come to us to join in the fun.

Take 10,000 steps back, you have to lie down, at least when you go down, take the time to write a thesis and what to say in the defense, right? What's the use of just pretending to be pitiful and cute? Can it be eaten as a meal?

I'm so!

Teacher Liu was not angry, but smiled and comforted Lin Yuxiang, who kept apologizing, a few words, and then asked Wang Xiaodong to guide her in essay writing, and then called Lu Zhou to the corridor.

After smoking a cigarette and glancing at the two students in the computer room, Mr. Liu smiled and said, "How about it, have you considered the suggestion I told you yesterday?" ”
