Research starts with PhD students

Chapter 41 If you have the ability, do it yourself!
"Yes, you must reject him."

"Just don't want to go!"

"What's so great about this kind of treatment? Isn't the ETH Zurich the alma mater of Einstein and the top university in Europe..."

"And an annual salary of 300,000 euros..."

Luo Yongjun couldn't continue.

As he spoke, he felt like going too, the temptation was too great.

That's ETH Zurich!

IDEA Alliance schools are known as the "No. 10 University in Europe" and have always been among the Q super universities!

Sudong University is also named Su...

However, the value of a doctorate degree does vary greatly.

An annual salary of 30 Euros is also very attractive.

In European countries with relatively high salary levels, the salaries of university professors and researchers are mostly between 5 and 10 euros.

More than 20 euros is the highest salary for scientific researchers, which is equivalent to the treatment of a director in a scientific research institution.

Working for only one year is equivalent to others working for several years.

Luo Yongjun swallowed his saliva and looked at Zhang Shuo cautiously, "Are you really going to refuse? Such a good treatment..."

Sun Xingli also said, "Yes, the treatment is too good. How about this, you ask him if he wants me? Not 30, 10 euros a year will be enough."

Gao Xiaohong rolled her eyes and said sarcastically, "You work for others for free, I guess they think you're an eyesore."

After she finished speaking, she looked at Zhang Shuo.

Zhang Shuo shook his head and said, "Don't even think about it." He turned his chair around and pointed his finger, "First, I don't want to work in Europe."

“Secondly, he was talking about annual salary, not directly giving me 30 euros, which doesn’t make any sense.”

“Third, the University of Eastern Zurich is also good. For me, it is enough to get a doctorate degree. It does not make much sense to change to a doctorate degree from the University of Zurich.”

"Fourth, and very important, I don't like working for other people."

Zhang Shuo turned to look at Luo Yongjun and said with a smile, "Teacher Luo, do you remember what I said on the plane? We can do this project ourselves."

"what?"

Gao Xiaohong and Sun Xingli didn't understand.

Luo Yongjun understood it. He thought Zhang Shuo was just talking, but he didn't expect it to be true?
Will the Institute of High Energy Physics really come to us?
He shook his fist fiercely and said forcefully, "Yes, we will do it ourselves! If they come to us again, we will ask for a high price."

"Three million won't do, we have to have four million!"

"Get your 30 Euros back!"

……

In fact, Zhang Shuo did not mention the most important reason.

That is a research question.

The 'center anchor point connection' algorithm was just a temporary and quick study to analyze small particle collision experiments.

The research is divided into two parts. One part is the central anchor point connection, which is the algorithm that associates all experimental data.

This algorithm, which relies on center-to-edge connections to cover data, is not very efficient and is highly replaceable.

Another one is the 'deviation assessment system'.

The 'Bias Assessment System' is a complete system, and the study only selected the part that was applied in experimental analysis.

'Bias Assessment System' is related to another study - LBNT analysis method.

The LBNT analysis method combines coverage algorithms and deviation assessment systems, and can perform deviation analysis on large experiments, and can even put different experimental data together for overall analysis.

The 'deviation assessment system' is, in fact, a means of digital code analysis.

In order to simplify the algorithm and make it more practical for small experiments, the study of central anchor point connection did not include numerical analysis.

When there are too many experimental parameters and no content for converting digital codes is added, the 'bias assessment system' will become extremely complicated.

In the study of connecting the central anchor points, the 'bias assessment system' is so complex that it takes a long time to sort out the logical relationship.

When the parameters double or more, its logical complexity will increase by several hundred times or more.

This is exponential growth.

举个最简单的例子，‘10中选2’有45种可能，而‘20选2’就有190种可能。

This is just 'option 2'.

If we add "Choice 3" and "Choice 4", it will be a huge project to sort out all the possibilities and form a complete logical closed loop.

Therefore, the LBNT digital analysis method must be used, otherwise it would be impossible to complete the research in a short time.

……

The Institute of High Energy Physics has already encountered this problem.

After the acceptance of the cooperative project with Zhang Shuo, Tan Zhiming returned to the Experimental Physics Center to hold a meeting and decided to develop software that can perform experimental simulation deviation analysis on large-scale experiments.

The project is called "Research on Deviation Analysis Algorithms for Large-Scale Experimental Simulations". The project leader is Cao Mengbo, director and deputy director of the Computing Center, and the core personnel involved include Bao Hexing, Liao Zhenyu, Liu Ye, etc.

Although the decision has been made to conduct algorithm research, in reality, the project has only reached the stage of preparing to submit an evaluation report.

For projects at the Institute of High Energy Physics, a comprehensive evaluation report must first be produced before the project can be approved by the Scientific Research Planning Office. Only after the project is successfully approved can funding be allocated and a comprehensive team be established to start research.

Now the project is stuck at the stage of submitting the evaluation report.

Only with an evaluation report can we know approximately how much the project will cost, how many people will be involved, and how long it will take to complete.

All of these need to be planned.

As the core members of the project, Bao Hexing, Liao Zhenyu, and Liu Ye, together with more than a dozen associate researchers, worked hard to figure out the operating logic of the deviation assessment system with dozens of parameters.

They must understand the operating logic clearly before they can evaluate the algorithm as a whole and the scale of the project.

Simply put, it is necessary to understand how many algorithm packages the program requires, how many lines of code it requires, and how large its scale is.

Now stuck here.

How can we sort out the logic of the bias assessment system with dozens of parameters? Without sorting out the logic, how can we know the scale of the research and how to make a budget?

How can we start a project if we can’t come up with a plan and make a budget?

Center for Experimental Physics.

Tan Zhiming presided over the internal meeting. He is not only an academician of the Academy of Sciences, but also the deputy director of the Institute of High Energy Physics, director of the Physics Center, and head of the Scientific Research Planning Department.

Cao Mengbo, director of the Computing Center, was busy preparing for the CHEP meeting and had not yet officially entered the project. The people who were doing the project preparation work were Bao Hexing, Liao Zhenyu, Liu Ye and others.

They all came to the meeting.

After the meeting started, Tan Zhiming asked directly, "You have been planning this project for a long time, why haven't you submitted the report yet?"

After asking, he said seriously, "This project must be done quickly, every second counts!"

"The central aiming point connection algorithm has received attention from various high-energy physics institutions, and they will also form a team to start developing analysis programs."

"This new algorithm came from the Institute of High Energy Physics and was completed by us. We have also completed the analysis of the small experiment."

"If we let them strike back and complete the analysis and research of the large-scale experiment first, what will happen then? Will they say that our soft power is not good enough?"

"With such a huge computing center and the first-mover advantage, why is it still lagging behind in algorithm programming?"

Tan Zhiming asked several questions in succession, and then called on Bao Hexing, "Professor Bao Hexing, please tell me."

Bao Hexing explained, “We encountered problems with the logic of the bias assessment system.”

"To be frank, it cannot be solved in a short time."

Tan Zhiming frowned and looked at Liao Zhenyu again.

Liao Zhenyu said more professionally, "In our analysis algorithm, the deviation assessment system only targets a dozen parameters."

"Large-scale experiments require more than 30 parameters to be analyzed. With each additional parameter, the evaluation logic becomes much more complicated, and the complexity increases exponentially."

"I and others have been sorting out the logical problems involved, hoping to form a logical closed loop of analysis."

“But it’s difficult.”

Liao Zhenyu said shaking his head.

Tan Zhiming asked bluntly, "Professor Liao, you don't need to explain the principle, just tell me how long it will take you to prepare."

"One year."

Liao Zhenyu raised a finger and said seriously, "I have discussed this with others, and it will take at least a year."

Bao Hexing nodded in agreement, "One year is too little. I think it should be one and a half years, or even more."

When Tan Zhiming heard the time, he immediately became angry. "It takes a year and a half to prepare the project. Will it take you ten years to finish it?"

“Is this the Three Gorges Project?”

"How much will this cost? One billion yuan?"

He was talking to Bao Hexing.

Bao Hexing's face turned red after being scolded. He slammed the table and stood up and angrily said, "If you think we can't do it, then do it yourself if you have the ability!"

"For the past half month, we have been working overtime every day and sleeping only four or five hours a day. What else do we want?"

“That’s the level we’re at!”

He said that and left.

Tan Zhiming was a little confused by the rebuke. He stared blankly at the door for a long time before saying, "This Bao Hexing seems to have a kind temper. I didn't expect that..."

The others curled their lips.

Bao Hexing spoke out their real thoughts: Didn’t they work hard?

The algorithm is too complicated, what can I do?
Tan Zhiming said that he attached great importance to the project, but he didn't even understand the basic principles and just stood there giving orders.

has no meaning?
Annoying!
