Research starts with PhD students

Chapter 19 Let them know what efficiency is!

Zhang Shuo had never cared about his clothing before.

It is true that he had never washed his coat, but that was not because he was sloppy, but because of the impact of his difficult life.

He only has two coats.

Apart from the one that was snatched away by Chen Lanjun, the other one looked a bit childish, and the cartoon pattern printed on it was really unacceptable.

The next morning, Zhang Shuo went to buy a few pieces of clothes that he liked, which quickly reduced his cash by half.

"The efficiency of the Institute of High Energy Physics is too low. Why hasn't the money been paid yet..."

He is even more looking forward to the funding and the million-dollar bonus.

No matter which world it is, money is not everything, but without money, nothing is possible.

People rely on clothes!

Zhang Shuo's appearance is not bad to begin with, and if he dresses more stylishly and appropriately, it seems that he will attract the attention of the opposite sex when he walks on campus.

After lunch, he went to the computer room.

The computer room was a bit deserted at noon, with only Luo Yongjun eating his packed meal.

Zhang Shuo walked in and put his coat on the table, then said with a smile, "Teacher Luo, I've finished washing it."

Luo Yongjun glanced at the clothes on the table and curled his lips in disgust. He ignored Zhang Shuo's teasing, but stood up, shook his clothes, then took them off and hung them on the hook on the wall.

When he turned around again, he smiled happily at Zhang Shuo, "My wife loves me so much that she picked out a new coat this morning and sent it to me specially. It cost one thousand yuan! Doesn't it look good?"

"nice!"

Zhang Shuo pulled the corner of his mouth to make a comment, then looked up and saw Chen Lanjun walking in.

Chen Lanjun came, but her coat didn't come.

When she entered the room, she glanced at Zhang Shuo without saying anything, as if nothing had happened, and just sat down in front of the computer she had been using yesterday.

Luo Yongjun pursed his lips tightly, pointed at Zhang Shuo's temple, and whispered, "Some female PhD students in the mathematics department are like this."

Zhang Shuo shook his head and changed the subject to the project. "Some of the program subcontracts have been completed, but the project funds have not yet been received. If someone is in a hurry, how about you advance the money, Mr. Luo?"

"I'll pay for it?"

"I mean, the kind that's very urgent." Zhang Shuo explained, "The funds will arrive soon, it's just a few days away."

“Um, ah, this…”

Luo Yongjun was speechless for a long time.

Zhang Shuo looked at him strangely and said tentatively, "I remember you just received 20,000 yuan in signing fees. You shouldn't have to pay too much in advance. It's just that you are in a very urgent situation."

"This one……"

Luo Yongjun simply spread his hands, picked up his phone and showed his bank card information, "It's 4,300, of which 4,000 will be deducted from the mortgage."

"Where's the money?"

"This is what men with families are like." Luo Yongjun explained helplessly, "My wife took it away last night. She was very happy and bought me a new coat."

Zhang Shuo could only sympathize.

At this time, Chen Lanjun suddenly raised her head and shouted, "Zhang Shuo, I will never accept money from my husband again!"

Zhang Shuo and Luo Yongjun looked over together.

Chen Lanjun lowered her head again, as if it was not her who had spoken loudly just now.

Luo Yongjun couldn't hold it in any longer and burst out laughing while covering his mouth.

Zhang Shuo walked to Chen Lanjun's side helplessly and said helplessly, "Senior, we have only met a few times, can you be a little more normal?"

Chen Lanjun turned to look at Zhang Shuo, a little confused, "What do you mean?"

"I don't have any idea of ​​finding a girlfriend!"

Zhang Shuo said this very seriously.

"I see."

Chen Lanjun looked obviously lost.

However, she didn't seem to be affected much. After Zhang Shuo walked back, she continued to work on the computer as if nothing had happened.

……

The computer room soon became busy.

Zhang Shuo found that he had underestimated the professors' enthusiasm for making extra money.

At one o'clock, the computer room was full.

Those who were writing programs seriously in front of the computers were all doctoral students, and the professors were surrounding Luo Yongjun, queuing up to urge them to review their works.

Some even gave debugging suggestions, "Try entering a random number!"

"Enter a negative number!"

"What happens if I reset all three numbers to zero? This loop will run infinitely. See! Something is wrong, right? We must change it!"

"His didn't pass! Look at mine!"

Subpackaging a program does not just mean that it can run. Problems must be found from all angles. The minimum requirement is to correct it until no obvious bugs can be found.

Luo Yongjun became very busy and couldn't rest for a moment.

Zhang Shuo also went to help, but later found that the work was extremely complicated and that his ideas might not be comprehensive, so he simply asked two professors to help with the review.

Now I have some free time.

He doesn't like doing unskilled and repetitive work.

This continued for several days.

The computer room was crowded every day and it was not quiet until the evening. Luo Yongjun was busy from morning to night, and the two professors who helped also did a lot of work.

Luo Yongjun offered them a high salary of 1,000 yuan a day and also said there would be an overtime allowance of 500 yuan on weekends, which greatly boosted the two professors' work enthusiasm.

With the professors' extremely enthusiastic work, the project progressed very quickly.

By the weekend, more than 180 program subpackages had been submitted, and the remaining program subpackages had also been distributed and were waiting to be submitted for review.

"At this rate, it will be finished next week."

“Once all program subcontracts have been reviewed, we can debug them together and then supplement the code based on the debugging results.”

"Probably, it will take one or two days? A week will definitely be enough." Zhang Shuo estimated the time and felt relaxed.

……

The first class on Tuesday is Li Weihua’s partial differential equations class.

Zhang Shuo and Li Weihua also became familiar with each other. Li Weihua also took on several programming subcontracting jobs, and they met several times in the computer room.

After the course, Li Weihua called Zhang Shuo and handed him a few printed papers. "These are research papers on second-order elliptic partial differential equations." "Two of them are numerical solutions, one is a proof of nonlinear asymptotics, and the solution of another special case is also very interesting..."

"But I still say that the research is very difficult. I have taken some time to think about it these past few days. It is indeed possible to find the boundary value using special methods, but the range will be very large and very random, so it will be difficult to go further."

Li Weihua explained, "In fact, the core is still fuzzy computing. The human brain has great advantages in fuzzy computing. Can you understand this? Computers can only perform rigid calculations."

"It's very obvious when using numerical methods. Substituting numerical values ​​sometimes relies on feelings and experience, rather than calculation results."

"The transformation of equations also requires the human brain, and computers cannot do the transformation."

Zhang Shuo nodded in agreement. "Teacher Li, you are right. The human brain is indeed superior. But we use computers to assist the human brain in making more accurate and faster judgments."

"Thank you, Mr. Li. I'll think about it carefully."

Instead of going to the computer room, he found a study room and started looking through his papers.

After reading the content of a paper and thinking carefully about my ideas, I feel that the research is still feasible.

He opened the system and tried to create a task -

【Task 1】

[Research project name: General algorithm for solving second-order elliptic partial differential equations (Difficulty assessment: C). ]

【Progress: 0.104%.】

(The task can be canceled. The current number of research coins required to cancel the task is 0.)
(The remaining progress requires 100 scientific research coins.)
【Research Difficulty: C.】

【Scientific research currency: 25. 】

“Difficulty C.”

"It's also a C-level research, but it's much more difficult to complete than the central anchor point connection algorithm..."

The research on the central anchor point connection was all in his mind from the beginning, and all he had to do was write the main framework and the main algorithm.

The current research is brand new. He currently only has an idea of ​​the direction and knows two difficulties that must be solved.

One is to find the boundary value.

Just as Li Weihua judged, finding boundary values ​​involves fuzzy mathematics, using computers to simulate the computing methods of the human brain.

The second is the determination of the asymptotic solution.

After finding the boundary value, we can define a range. To make more precise calculations, we must continue to narrow the range. However, the problem is that the results of substituting numerical values ​​into partial differential equations are not necessarily linear, and many of them show jumpy results.

How to compare and know which value is closer to the exact solution (if an exact solution exists), that is, how to determine the asymptotic solution is also a difficult point.

……

That afternoon, the project funds for the Institute of High Energy Physics arrived.

The college’s finance department was indeed very efficient in handling the project, and Zhang Shuo and Luo Yongjun were notified as soon as the funds arrived.

Zhang Shuo's personal funding (bonus) of one million also arrived quickly.

Administrative Director Wang Duoju also sent a private message using a messaging app, "Student Zhang Shuo, your project funding has arrived. Have you received your personal funding?"

Zhang Shuo replied with three words, "Delivered."

"That's good. Your project can be officially launched now. If you have any questions about the project, you can come to me."

After she posted it, she added, "You can come to me if you have any problems in life."

"Thank you, Director Wang."

Zhang Shuo gave a polite reply.

"You're welcome. This is my job. The school will definitely give strong support to outstanding talents like you!"

After Wang Duoju sent the message, she talked about recent events. "I heard that you have found many professors and doctoral students to work together and have provided a lot of funding, which has also helped us share the work. Project funding in the college has always been a problem."

“It’s very difficult to apply for funding for pure mathematics projects…”

She said a lot in a row.

Zhang Shuo occasionally sent a message to express his agreement, but when he came to his senses, he felt very strange. Why was he chatting with a 50-year-old lady?

In his previous life, he was only thirty-six years old.

He looked at Chen Lanjun at the door.

This senior student has a lively personality. Sometimes, she seems very enthusiastic, and sometimes, she speaks strangely. But when she works seriously, she is still quite quiet.

While Zhang Shuo was thinking, he saw Chen Lanjun suddenly stand up, pointing at the screen and shouting, "Look! The school has issued an announcement!"

In one word, it attracted everyone.

"I take back what I just said."

Zhang Shuo silently shook his head and walked over to take a look at the situation.

The school released an announcement related to the project, which roughly said, "Our doctoral student Zhang Shuo and Professor Luo Yongjun have reached a cooperation with the Institute of High Energy Physics to develop an experimental simulation data analysis algorithm."

The announcement also specially introduced Zhang Shuo and Luo Yongjun.

There is relatively little introduction about Zhang Shuo, because he is just a doctoral student without any special resume, and it is impossible for him to talk about the embarrassing experience of "his master's thesis being cancelled".

Therefore, the introduction only used some words of praise, including "extremely outstanding", "recognized by many professors", "recognized by two academicians", and the last sentence emphasized that "Zhang Shuo is an outstanding doctoral student trained by Soochow University."

If you just browse it, you would think that Zhang Shuo studied for his undergraduate and master's degrees at Soochow University.

Luo Yongjun's introduction is much richer.

His resume was included in the announcement, and the published papers were all described as "extremely excellent." Just by looking at it, you would have thought that they were all published in top journals.

In fact, most of them are just ordinary SCI, and there are very few in Zone 2.

This announcement greatly satisfied Luo Yongjun's vanity. He returned to his computer, staring at the announcement and laughing.

Zhang Shuo walked to Luo Yongjun's side, shook his head and said, "Why did the school issue the announcement only now?"

"Isn't that normal?" Luo Yongjun looked up and asked in confusion, "It was only confirmed last week, and the funds arrived today. I guess the school communicated with the Institute of High Energy Physics again, so they issued a notice."

"I mean……"

Zhang Shuo pursed his lips and whispered, "The research is almost done. It will probably be this week. They just issued the announcement, and we have already submitted the project for acceptance. Isn't that a bit bad?"

"This~~"

Luo Yongjun also hesitated. He thought for a while and said, "How about delaying it a little longer? Submit it for acceptance in two months?"

“Acceptance also takes time.”

Zhang Shuo shook his head. "The Institute of High Energy Physics may have other requirements, and the time required is uncertain. If you delay for three months, you will be admitted to the Institute of Science and Engineering..."

"Uh~~"

Luo Yongjun slammed the table and made a decision immediately, "No matter what, finish it quickly and submit it quickly, just to let them know what efficiency means!"
