Student dormitory Building 17, 3rd floor.

Ding Zhiqiang was sitting at the computer desk, staring at the screen with a wicked smile, and the screen displayed was the post of 'pay attention to stepping on thunder', and he read the content several times in a row, and it felt like 'completing revenge'.

Last semester, the memories of the "Partial Differential Equations" course were so painful.

If you are just forced to go to class and study, it's okay to get used to it, and some teachers have high requirements for students, and it's normal to skip classes twice and not give them, and you have to listen carefully in class, and deduct points for being late, etc., it's just a step further.

However, Ding Zhiqiang's feelings are different from those of other classmates, and the reason why he recalls feeling 'miserable' is because he posted a post last semester, talking about the strict problems of "Partial Differential Equations", and gave the other party the nickname of 'devil'.

In addition, he also went to the Academic Affairs Office to report it.

Since then, Ding Zhiqiang always felt that the other party knew that he had made the report, and he had to answer questions significantly more times than others in class, even if he was listening carefully, he would be called up to answer questions.

Ding Zhiqiang was afraid that the other party would 'wear small shoes' for him, after all, the other party was a teacher, and he was just a student.

So at the end of the semester, he worked harder than the others, and spent a lot of time on the "Partial Differential Equations" course, in order not to let the other party pick out the problem.

Then, he got a high score, 89.

A difficult professional mathematics course, with a score of nearly 90 points, is already a high score, and considering that the usual score is not a full score, the paper score must be quite dazzling.

Although he was not 'wearing small shoes' in terms of grades, Ding Zhiqiang still felt very depressed when he recalled that he spent every class nervously and was worried about failing the subject after the exam.

When he saw that the course of "Partial Differential Equations" appeared on the course selection list, he suddenly felt that the opportunity for 'revenge' had come.

Post!

Boycott!

He, Ding Zhiqiang, wants to remind others not to be deceived and not to experience pain.

After several people in the dormitory came back, Ding Zhiqiang immediately shouted, "Brothers, go to the campus forum to help with the post!" Remember last semester's "Partial Differential Equations"? That teacher Wang Hao has started class! ”

"Isn't it?"

"He also takes electives? Those who chose must have regretted it......"

"Kill him and don't take his class!"

Several people in the dormitory have logged in to the campus forum to like the post, the number of people in the campus forum is relatively small, and a few people help to top the post, and the post can be regarded as hot.

For a while, it seemed that everyone was boycotting Wang Hao's class.

Half an hour later, an account finally questioned, "I have listened to Mr. Wang Hao's class, and he gave a good lecture, anyway, it is much better than our teacher Zheng Yaojun!" ”

Then there were other replies, "Why boycott Mr. Wang Hao?" I think Mr. Wang Hao is very good, super powerful, he is only twenty-five years old, a doctor of mathematics and an associate professor! ”

"Did you read the school news during the holidays? Junior brother, you have no future, Mr. Wang Hao, but you have won the best in the top international academic conferences, and you have also published a paper in Acta Mathematica Sinica. ”

"STACS, do you understand? ACTA-MATHEMATICA, YOU KNOW? ”

"That's great, if you don't choose, I don't have to rush the class! It's best to choose me alone, so that Mr. Wang Hao is familiar with me, and when the time comes, if you have any questions about the paper, you can ask him. He is much more professional than my tutor, SCI expert, ten articles a month! ”

……

After Ding Zhiqiang posted the post, he continued to read it for a few minutes, and felt that it had been 'blacked', so he didn't continue to pay attention to it.

The same goes for the individuals in the dormitory.

The time before the holidays is the most leisurely, and if they don't get together again and don't come to the 'Black Five Row', it's a little sorry for college life, and they quickly indulge in the fun of games.

At 3 p.m., the course selection system was opened.

The students are waiting in front of the computer early, ready for the new semester's 'class rush battle'.

Ding Zhiqiang glanced at the class schedule, opened the campus forum, and saw more than a dozen new replies.

Isn't it just on a hot search, saying that a lot of papers have been posted? But there are also a lot of people who question it!

A few of the people who replied seemed to be graduate students!

What did STACS win? PUBLISHED IN ACTA-MATHEMATICA?

Isn't it amazing?

DING ZHIQIANG ALSO SAW THE SCHOOL NEWS, HE DIDN'T KNOW WHAT STACS WAS, AND HE DIDN'T KNOW WHAT THE PAPER PUBLISHED BY ACTA-MATHEMATICA REPRESENTED, BUT HE JUST GLANCED AT IT AND DIDN'T CARE.

Now it seems that it is indeed very unusual!

He couldn't help but think seriously, "That teacher, the level of teaching is really high, and he is also a SCI expert......

"I'm also preparing for the graduate school entrance examination, and when I go to graduate school in the future, I also have to write a thesis, so for the comfort of the future, it seems that it's okay to feel uncomfortable?"

He thought about it and immediately shook his head, "No, it's really stupid to take his class!" ”

At this time, I heard the shouting next to me, "You can choose!" ”

Ding Zhiqiang quickly switched the page and selected a public elective course that he was optimistic about, and then hesitated slightly, and then looked at the surging number of course candidates for "Introduction to Data Mining", knowing that there was no need to consider it if he hesitated.

He almost subconsciously clicked on 'Elect a course'.

Then, 'OK'.

"Whew~~ chosen!"

Ding Zhiqiang experienced a refreshing feeling similar to buying 'limited-time rush products', and after reacting, he was stunned, and couldn't help but scold angrily, "I@!! ”

"How do I ......?"

He was just about to scold loudly, glanced left and right at the others, and stopped with a weak heart, "If they know that I chose "Introduction to Data Mining", will it be ......?"

"Kill my ?!!"

……

At the same time, the office of the comprehensive building was also lively, and Wang Hao and Luo Dayong were paying attention to the course selection.

Although it is not involved in the cost of lessons when students sign up for classes, teachers will also want their classes to be popular with students.

Luo Dayong is a small course related to language design, with a limited number of only 50 students, and similar courses can let students know more about a programming language, which is still very popular with computer students.

Wang Hao has a big course of 200 people, and graduate and undergraduate students can sign up, plus the content is very professional 'data mining', which is a little unattractive to the student group.

After the backstage was refreshed, Luo Dayong immediately smiled and said, "The selection is full, the course I opened is not bad, Wang Hao, what about you?" ”

Wang Hao also nodded with satisfaction, "Mine is also full, I really didn't expect that this class could also be popular." ”

"A lot of the students who choose courses are graduate students!"

Luo Dayong immediately grasped the key, "You are a celebrity in the school, ten SCI papers a month, and you have won awards at international conferences, I heard that many students want to ask you about writing papers." ”

"Now graduate students have to write papers, and having an excellent SCI is a plus for finding a job after graduation."

Wang Hao clicked on the list of registered students and found that more than half of them were students in the first and second years, and several students were familiar with their names, "Deng Bin, Gu Youyou, Li Jiaxin, ......"

"Ding Zhiqiang?"

He locked on a name, noticed that it was "Physics Department, junior", and a figure appeared in his head, with short hair, a round face, and small eyes, looking a little cringe, maybe the reason for being introverted?

"It should be him, who has answered questions several times, is very serious, but may be a little introverted!" Wang Hao shook his head.

After Luo Dayong looked at the course selection, he left the office and went outside.

It was now the military training period, and he was assigned to a freshman class, and occasionally had to go over to see how it was going.

As a homeroom teacher for the first time, I still want to perform better.

Wang Hao continues to do research, and continuous learning is still helpful, and the inspiration value of 'Task 2' has accumulated to '97' points, which is only three points short of reaching 100, but it is very difficult to improve the last three points of inspiration.

I've been reading books in the morning and afternoon, but I haven't even increased my inspiration at all.

He simply started researching, following the train of thought in his mind, and the research was stuck on a problem, which is simply the calculation and evaluation of the 'Rubik's Cube' situation.

This is very similar to the classical 'maximum flow' problem, which is to find the optimal pathway in a complex situation.

A classic example of the maximum flow problem is that there is a network of underground water pipes, and now the waterworks are sending water to the network, and people are at one point receiving water.

Due to the different ages of pipeline construction, the water flow that different pipelines can withstand is large and small, so what is the maximum value of water that can be received at one time under the condition that the water input from the waterworks is not limited?

This is a simple question, but it is very complex to deal with.

The point he got stuck on was not to completely solve the problem of maximum flow, but to evaluate the whole and screen out the solutions that would cause less water to be received in a precise calculation way.

Wang Hao thought about it for a long time and didn't have a clue, so he couldn't help rubbing his head hard.

Yan Jing asked curiously, "What's wrong with you?" ”

"There's a question I can't think of." Wang Hao continued to rub his head, he felt that he should talk to other people, there were two doctors of informatics and a master of informatics in the office.

As the only 'Master of Informatics', Sister Zhu Ping and Zhu quickly raised her hand to give up, "Wang Hao, you are such a genius." If you can't think of a problem, I certainly can't think of either. ”

Yan Jing nodded in support.

Zhang Zhiqiang asked with interest, "What's the problem?" Let's talk about it, three stinkers, a top Zhuge Liang, maybe we can help too! ”

Zhu Ping glanced left and right.

There were four people in the office, except for Wang Hao, who asked questions, she was left, Yan Jing and Zhang Zhiqiang.

So, they're all stinkers?

Wang Hao said, "It's the biggest problem, you should know, right?" The problem I want to solve is that in a fixed system, the computational evaluation is done in a general way......"

"Ula Ula~"

He went on to say a whole bunch of professional stuff.

Yan Jing is not an information professional, so she can't understand it for a long time, Zhu Ping is even worse than Yan Jing, and she simply brushed her phone halfway through it.

Zhang Zhiqiang continued to listen carefully, nodding his head from time to time.

After Wang Hao finished speaking, he pondered carefully for a long time, and pursed his lips vigorously, "Is this question ......?"

Everyone else looked at it.

Ten seconds later, he choked out, "...... You better ask Luo Dayong! ”
