More than 30 hours of continuous work, and in such a state of high concentration, this has made Lu Zhou's spirit on the verge of limit.

After returning to the temporary dormitory, Lu Zhou didn't change his clothes as always, his head hit the pillow, and he fell asleep.

When he opened his eyes again, the sun outside the window was already hanging obliquely in the sky.

took out his mobile phone and looked at the time, it was already half past five in the afternoon, Lu Zhou couldn't help but sigh in his heart.

"The schedule is completely reversed, and it seems that tomorrow and the next two days, I will have to take some time to adjust the schedule."

I really slept to this point unconsciously, and no one came to call him halfway.

There were more than a dozen missed calls on the phone screen, including Chen Yushan, two teammates, Teacher Liu and the counselor, and his roommate.

Lu Zhou opened WeChat and sent them a message in turn, explaining the reason for the missed call.

After doing this, Lu Zhou put on his travel bag and was about to return the key to the dormitory when a phone call came.

The caller was Chen Yushan.

As soon as the phone was connected, a pleasant voice came from the other end of the phone.

"Lu Zhou! How does it feel? ”

Lu Zhou: "It feels okay." ”

Chen Yushan then asked: "I heard that this year's topic is difficult, which one did you choose?" ”

Lu Zhou: "A, the one about Chang'e-3." ”

Hearing Lu Zhou's answer, Chen Yushan's eyes widened in surprise and said, "You actually chose that question!" Can you understand the things given by the question? ”

Lu Zhou thought for a while and replied: "It's okay, although the proposition of aerospace looks quite scary, it is not difficult to convert it into a mathematical problem." ”

"You don't think it's difficult," Chen Yushan sighed, "One of my roommates also participated in the competition this year, and I originally wanted to take a country back and fight for the opportunity to go to the insurance research institute." As a result, when she saw the title of the competition, she was dumbfounded. ”

Can the National First Award of the Mathematical Modeling Competition add points to the research institute?

Lu Zhou was stunned.

No wonder that Lin Yuxiang hugged his thighs so desperately.

I see, so it makes sense.

Lu Zhou: "Which question did she choose?" ”

Chen Yushan: "Question B, the one that designed the folding table." ”

That's tragic.

Lu Zhou sighed in his heart.

At least seven teams in a computer room chose question B, and the remaining three teams didn't notice it, and it is not even ruled out that one team of Lu Zhou in the entire computer room chose question A.

"And how does she feel?"

"It's hard, when it comes to structural mechanics, ergonomics, in short, it's troublesome and troublesome. In her words, what is the calculation of a broken table. Chen Yushan sighed, "It's still a normal topic for the specialist group, one is designed for pig farms, and the other is for medicine storage." Let's not talk about it, you can go to dinner too, I guess you just got up, I'll go to comfort and comfort my roommate. ”

"Well, see you then."

Lu Zhou hung up the phone, just in time to see Lin Yuxiang reply with a message, saying that the MD5 code and the paper had been successfully uploaded, she and Wang Xiaodong went back to school first, and if there is anything that can help in the future, please be sure not to be polite, and invite him to dinner alone another day to express gratitude, etc.

Lu Zhou thought about it and replied, "You're welcome".

The competition is over, although others paddled seriously, but they have been a "logistics soldier" for three days, which can be regarded as playing a role.

No matter how much you complain, you can't justify it.

The school bus has already left, and the next one is tomorrow morning.

The accommodation conditions in the old campus are really not very good, and he has not taken a shower or changed his clothes for three days, Lu Zhou really doesn't want to stay here for a moment.

He took his travel bag to the school gate, where he ate a bowl of noodles casually, and then took the subway back to the new campus.

……

"One-two-one, one-two-one......"

"Throw your arms up! Legs move! One and two for Lao Tzu, don't be lazy! ”

There was a whistling sound on the playground, and freshmen dressed in green clothes were being trained by the instructors.

Looking at these energetic newcomers, Lu Zhou couldn't help but sigh with emotion, it's good to be young, and then walked in the direction of the dormitory building.

When I returned to the dormitory, as soon as I opened the door, three animals surrounded me.

"Elbow, how did you do in the exam?"

"Are you sure to be shortlisted? Liu Rui said again that he was forced to rest. ”

"I'm really forced to stop," Liu Rui said with a smile, "Why don't you believe me?" I looked at the two questions with a confused face, and I still understand a little bit about the second one, or rely on our team's thighs to write programs while helping me model, so it's good to win a provincial award. ”

Shi Shang impatiently moved this guy away: "Okay, okay, you hang, you hang, if you don't hang, I look down on you." Let's go aside, we asked the elbow. ”

Huang Guangming leaned over and asked, "Elbow, how are you doing?" Is question A difficult? ”

Lu Zhou said casually: "It's okay...... Liu Rui, what about you? ”

"It's so hard...... There are so many problems that math alone can't solve. Liu Rui shook his head.

That's inevitable.

Whether it's math or programming, it's just a tool to solve problems. The core idea of mathematical modeling is also here, so the competition selects talents who are good at exams, but applied talents who are good at using mathematics to solve practical problems.

Otherwise, why is the national award high in gold content? Gao is here.

Unlike the math exam, there is nothing to discuss in the mathematical modeling competition, and the layman can't read the paper with it, let alone the paper is still in the USB flash drive.

After being dragged and questioned for a long time by two roommates who planned to participate in the competition next year, Lu Zhou finally got rid of the entanglement of the two animals, climbed the ladder to the bed, and opened his notebook.

If you hang up the machine for so long, don't have a long progress bar at all, it will be a big loss.

However, when Lu Zhou opened the lid of the computer and looked at it, he was immediately angry.

MMP。

The progress bar has risen so much compared to before he left.

Hang Nima's machine, don't hang up, it's a waste of electricity!

Lu Zhou was angry, turned off the computer without saying a word, grabbed two borrowed programming books and stuffed them into his shoulder bag, and went to the library for self-study.

……

After the Mathematical Modeling Competition, Lu Zhou finally had a period of leisure.

Every day, I carry two books on my body, one "Data Structure" and one "Artificial Intelligence Programming Examples", read math class, physics class, except for physical education class, other classes basically sit in the classroom and do their own things.

The only good thing about college is this, you can control your own time.

Except for the leaders of the department and some old professors, the general teacher only talks about himself at the top, at most he names the people who are absent from class, as for what the people sitting below are doing, it generally doesn't matter, as long as you don't affect his lectures.

Usually either in class, or in the library self-study, or in the dormitory typing and teasing artificial intelligence Xiao Ai. Lu Zhou unexpectedly found that chatting with Xiao Ai can promote the growth of the progress bar, and the efficiency is much higher than simply hanging up.

To this end, Lu Zhou wrote a small program in Python, opened up an interface between Xiao Ai's main program and QQ chat, and registered a new QQ number, named "eye".

In this way, he only needs to hang the trumpet on the mobile workstation and send a message to the trumpet through his hand Q, and the message can be read by the applet and entered into Xiao Ai's dialog box.

This is equivalent to using a third-party chat tool to indirectly interact with Xiao Ai from a distance. Considering Xiao Ai's absolute control over the "mobile workstation", he can even use it to remotely control his own laptop.

Let Xiao Ai execute a certain program, and Xiao Ai will automatically execute it.

For example, he only needs to enter the shutdown, and Xiao Ai will turn off the computer for him.

It's kind of cool to think about it.

Of course, for the sake of security, he added a security lock to the core code of this applet. That is, only the message sent by his own QQ number will be received by the applet and entered into Xiao Ai's dialog box.

Even if someone searches for his trumpet through someone nearby and sends a message to it, it will not cause any impact.

After all, the only one who can be identified is his own account.
