Research starts with PhD students

Chapter 103 Mathematics Paper, the easiest to write? The report must have a lot of problems!

The scores for the graduation defense came out that day.

A perfect score of one hundred.

All the judges on the defense committee gave full marks. Most of the judges didn't even understand the report, so they couldn't find any reasons to deduct points.

Chen Tianze did understand it, but it was only after Zhang Shuo's one-on-one tutoring and targeted answers that he figured it out.

Of course, it doesn’t matter how many points you get.

The final evaluation of the graduation thesis was just one word - "excellent".

Any score above 90 is considered 'excellent'.

Zhang Shuo finished his graduation thesis defense and felt relieved, but then he felt a little empty. Graduated?

Graduated already?
When I traveled through time half a year ago, my life as a doctoral student had just begun.

I will graduate in half a year, and I will no longer be able to say that I am a doctoral student. I feel a little... regretful?

The school has already prepared the graduation certificate and degree certificate, and all that is left is to sign and enter them.

Everything is handled quickly.

The school really hopes that Zhang Shuo can graduate, so that they can confidently say to the public, "Zhang Shuo was trained by Soochow University."

Otherwise, if you are just studying for a PhD in a university and haven't graduated yet, how can you say that you are training?
Zhang Shuo’s graduation ceremony was also simple.

In a small auditorium of a school, tutor Luo Yongjun, dean Tan Youming, mathematics department head Wang Duoju, vice president Zhang Qiu Sheng and others were all present.

Most people just come to watch the fun.

Many leaders and professors came, but Zhang Shuo was the only student who graduated. Dean Tan Yongming held the graduation certificate and degree certificate in both hands and solemnly handed them to Zhang Shuo.

"Student Zhang Shuo, this is the last time I'm going to call you that."

"You have excellent grades and thesis in school. After evaluation by the academic committee, you are allowed to graduate early and awarded a doctorate in science."

“I wish you will continue to reach new heights and achieve greater success in your academic career!”

Zhang Shuo took the diploma and degree certificate with both hands and said solemnly, "Thank you to Sudong University for training me, and thank you to all the teachers for teaching me!"

"I will deeply remember the school's wishes for me and strive to continue to move forward on the academic path in the future..."

……

The end of August is the time when students start and return to school.

Zhang Shuo graduated.

He was walking alone on the school road with a shoulder bag on his back, looking at the students on both sides carrying their luggage back to school, feeling that "I can never go back to the past".

The identity of a student has left him, and he will be a researcher in the future. Looking back on his experiences in the past six months, he finds it difficult to describe his feelings.

"Senior, long time no see!"

A girl waved from afar and walked over quickly with her suitcase.

It’s Zhong Yijing.

Zhong Yijing walked closer, her eyes somewhat resentful, "Senior, I sent you messages during the summer vacation, but you didn't reply..."

"Too much information to read." Zhang Shuo explained, then changed the subject and asked, "Did you just return to school?"

Zhong Yijing nodded slightly, then smiled and said, "I haven't congratulated you yet. You have completed so much research. I don't quite understand the research at that conference, but I know the Jebov conjecture."

"Thank you."

Zhang Shuo also exchanged pleasantries after he finished speaking, "How was your summer vacation?"

"not good."

"what happened?"

Zhong Yijing pursed her lips tightly and said depressedly, "I stayed at home for a month, and then I found that I might not be suitable for studying mathematics. I couldn't understand the papers you published."

"What paper?"

Zhang Shuo was puzzled. "Why do you want to read my papers? Some of them are very difficult and I really can't understand them."

"The target solution transformation of the nonlinear Schrödinger equation." Zhong Yijing explained, "The paper published in Applied Mathematics and Computation."

Zhang Shuo finally reacted after hearing this.

The target solution transformation of the nonlinear Schrödinger equation is just a small transformation method. He summarized it in a paper published in "Applied Mathematics and Computation".

Then, I didn’t care.

"What do you think of this paper?" Zhang Shuo asked puzzledly.

"It's not because of you!"

Zhong Yijing sighed bitterly, "At first, Professor Tong asked me to study the nonlinear Schrödinger equation and write a paper around this equation."

"I study the existence of solutions to equations, and you just found a way to solve them..."

She said with sadness in her voice, "Then, Professor Tong asked me to read your paper and told me to first understand the content of the paper and then find an equation of a similar type to study."

"Oh~~~"

She sighed, "I didn't even understand the paper, let alone anything else."

"Senior Zhang Shuo, you have successfully made me lose my direction!"

"That's it."

Zhang Shuo smiled and consoled him, "Actually, you don't have to worry. Mathematical papers are the easiest to write. As long as you have a clear direction and study a small method, you can finish it quickly."

"Think about it, a math paper only needs to have content. Write out the core. During the defense, the judges will also ask about the main content. The other requirements are not high."

"Just follow what the teacher says and think of the core content, and you'll be fine!"

Zhong Yijing nodded thoughtfully, "It seems to be like that."

"Come on! Believe in yourself!" Zhang Shuo gave Zhong Yijing a familiar thumbs-up. He comforted his schoolmate and felt relieved.

Zhong Yijing looked sideways at the senior's departing back, frowning as she thought about what he had just said. She didn't know why, but she always felt like she had been fooled.

Which mathematics paper is the easiest to write?

……

Zhang Shuo went to the Quantum Research Institute. He asked Qiu Zhichao to confirm the personnel who would go to the Computing Center, and then they bought plane tickets and booked a hotel together.

The next morning we set off for the capital.

There were six people in the group.

In addition to Zhang Shuo and Luo Yongjun, there are two researchers sent by the Quantum Research Institute, one associate researcher, and the other is Zhou Jianxin, who is in charge of school-enterprise cooperation projects. He will be responsible for communicating and handling matters related to project acceptance and settlement with the Computing Center.

While Zhang Shuo and his team were at the airport, the Computing Center held an internal technical meeting on large-scale experimental deviation analysis algorithms.

Recently, the project team has been doing one thing, which is to study the algorithm planning content submitted by Zhang Shuo.

Their work direction is very clear. They first study the algorithm plan submitted by Zhang Shuo. After making sure there are no problems with the plan, they write a program according to its content to complete the algorithm work.

Cao Mengbo, Cui Kaiwen and others placed their bets on their trust in Zhang Shuo.

Trust Zhang Shuo and develop the algorithm according to Zhang Shuo's plan.

When this direction was proposed, Shi Qiuling and Cheng Yaoxing, who had just joined the project team, were surprised. They found that everyone else supported it.

For example, Liu Ye.

Liu Ye said very clearly, "Academician Tan led a team to study the deviation algorithm of large-scale experiments, and said he wanted to find a new direction. This is simply a fantasy and impossible."

"Academician Tan doesn't understand algorithms. He may think that research is very simple. In fact, even foreign data teams, including the data center of the Nuclear Organization, are doing research in the direction Zhang Shuo mentioned."

Liao Zhenyu also agrees with this view. "We previously wanted to use the small-scale experimental deviation analysis algorithm as a basis to conduct algorithm research on large-scale experiments, but later we found that it was simply not feasible because the logical relationship between the parameters was simply unclear."

“Even if the parameter relationships are clearly sorted out, the workload of writing programs will be huge because they are too complicated. Even if the program is completed, the amount of calculation will be very large, and even supercomputers may not be able to support it.”

"So the simplest and most direct way is to just follow Zhang Shuo's plan."

After Zhang Shuo submitted the algorithm plan, the project team has been studying it carefully.

In algorithm planning, the core algorithm is the most difficult to understand.

The core algorithm is the experimental digital transformation.

The main content of the large-scale experimental deviation analysis algorithm is the digital conversion of simulation and experiment, and then the comparative analysis of the converted numbers.

Analog-to-digital conversion is directly related to experimental data parameters. People who have been dealing with experimental parameters for a long time can understand the judgment mechanism of analog-to-digital conversion.

The most difficult part is the digital transformation of experiments.

There are many things to analyze in experimental digital conversion, and there are also many related contents, including the judgment mechanism, which is not easy to understand.

“The most important part to understand is the digital transformation of the experiment.”

Bao Hexing said, "As long as you understand the experimental digital conversion method and make sure the logic of the algorithm is perfect, the rest will be fine."

Shi Qiuling said, "My team has also studied it. In the experimental digital conversion module, there are several logical judgments. The text description is a probability judgment, but I still don't understand..."

She said and shook her head.

Cheng Yaoxing also said, "It's not just the judgment part, but also the probability analysis of each parameter. Some calculation modules are described as 'logical judgment', but the whole thing is unclear."

One by one, researchers began to express their opinions.

Cao Mengbo asked someone to record them one by one.

The purpose of their meeting was to summarize the difficulties in algorithm planning, and when Zhang Shuo arrived, they could ask questions one by one so that they could understand everything as a whole.

……

Experimental base, a small office.

Tan Zhiming and Zhao Chunlai were also discussing algorithm project issues.

Tan Zhiming talked about the project team of the Computing Center, "They have obtained Zhang Shuoshuo's algorithm plan and have been studying it for a long time. I feel that there is no hope."

"I don't know what Cao Mengbo was thinking. Is it possible for an outsider to make the overall plan for such a huge algorithm?"

"Zhang Shuo's algorithm is indeed very advanced, but this kind of research can only be done by a team. One person can't think so thoroughly and there will always be many problems, not to mention that it was completed so quickly."

Zhao Chunlai nodded in agreement, then said, "But shouldn't we do research according to Zhang Shuo's direction of thinking?"

"His idea of ​​digital conversion and digital comparison is recognized by many people."

Tan Zhiming shook his head. "It can be used as a reference, but it is impossible to copy it."

"That's just an idea, it may not be realized. I think this kind of research should be done steadily and step by step."

“My plan is to complete the algorithm planning within two years, and then spend another three years to complete the program and perfect the algorithm, and strive to complete the project within five years!”

Zhao Chunlai thought for a moment and said, "Five years shouldn't be too long, but what if the computing center is faster than us?"

The issue he raised is crucial.

Wu Jianning decided to separate the projects, but everyone knew that the Institute of High Energy Physics could not support two identical large-scale algorithm projects. If others knew about it, he would most likely be accused of wasting funds.

The reality is, whichever project team is more certain to complete the research will be able to proceed with their project.

Otherwise, you just have to stop.

Tan Zhiming said, "I was worried at first, but I don't think there's anything to worry about. The computing center used Zhang Shuo's algorithm planning. He completed it so quickly, so there must be a lot of problems."

"This kind of super-large algorithm has a very complicated planning. It's better to start over from the beginning than to send it back for revision and revision again."

"You see!"

"Zhang Shuo will go to the computing center today to make an acceptance report. There will definitely be a lot of problems."

"By then, Cao Mengbo will also be anxious..."
