From University Lecturer to Chief Academician

Zheng Guofeng was already fifty-three years old, and he said he was still in the middle-aged and vigorous stage, but he was a bit old after all.

For people of this age, half past one in the morning is the time when they sleep most soundly.

The phone on the table rang suddenly.

As the chief researcher of a confidential scientific research institution, the mobile phone is generally not turned off, because there are occasional emergency communications, but because the number is not disclosed to the public, there will be no calls in the early morning.

If so, it could be a big deal.

Zheng Guofeng woke up when he heard the phone ringing. He quickly picked up the phone. Looking at the person on the caller ID, his face turned dark.

Liu Rongxing?

There is no way this guy has an urgent problem on the phone!

Zheng Guofeng answered the phone with a dark face, scolded Liu Rongxing half to death in his heart, and his tone was definitely not good, "What's the matter! Director Liu! Are you disturbing people's sleep?"

Liu Rongxing has a good temper.

He had just been called up not long ago, so of course he understood what it was like to be woken up by the phone, he suppressed a smile and said, "Professor Zheng, you don't know, I've stayed up all night for your sake."

"Your question has a result. I have already sent it to you through the intranet. You can log in and have a look."

"Okay, that's it, don't delay until tomorrow morning!"

Liu Rongxing reminded him and put down the phone after speaking.

Zheng Guofeng was stunned on the bed for a long time, and he continued to scold Liu Rongxing in his heart, "If there is a result, just say no, and you still need to check it on the computer?"

"Are you afraid that I'll be confused and forget about it in the morning after listening to it at night?"

He was a little confused, but he still got up from the bed and turned on the computer. After logging in to the intranet, he found a confidential file sent by Liu Rongxing. After he clicked to unlock it, he couldn't take his eyes off it.

Zheng Guofeng is more professional than Liu Rongxing. What he sees is not just the title introduction, but he can know the specific content after a quick glance.

Trajectory correction of 3D functions!

Detailed calculation method!

"Without the content of mathematical analysis, can you directly use a computer to do calculations?"

"Are you a little god?"

Zheng Guofeng suddenly became extremely energetic. He looked at it carefully from the beginning, and carefully understood it. It took one night to see it. When he realized it, there was already light outside the window.

He glanced at the time and knew that he couldn't finish it, so he quickly lay down on the bed again, but couldn't fall asleep at all.

He couldn't help but continued to scold Liu Rongxing secretly, "This guy named Liu must have done it on purpose. Why don't you just pass it on to me in the morning and keep me from sleeping?"

"What a lack of virtue!"

...

It's another day.

The main research building of Institute 137 became lively again.

In the side office on the first floor, Ding Hui was sorting out the documents. He was in his thirties and was relatively young in the institute, but because of his high level of mathematics, he was a key talent to be cultivated in the institute.

Ding Hui is also a representative of the "young faction" in the institute, or the representative of the "novel faction".

The younger group will have a lot of new ideas. They dare to innovate and explore. Regarding the research direction of missile orbits, they all support exploring new orbit change models instead of continuing to use the old methods.

Ding Hui was also talking to others, "We should find a new method."

"After the missile is launched, various orbital changes can be used, but the peak period of interception is when it falls to hit the target."

"In this section, the use of Qian Xuesen's ballistic is a method, but Qian Xuesen's ballistic has limitations, and it may be analyzed. Many conventional missiles cannot use this complex ballistic."

"I think it is possible to use the sideways method to create thrust, but it is difficult to calculate the route..."

He said and shook his head.

Yuan Zhilin also walked into the office. He did not support Ding Hui's idea, because the method Ding Hui said felt hopeless.

Of course he knew that way was better, but how to do it?

Can't just say no to do it?

If we continue to study Qian Xuesen's ballistics and develop several more orbit changing modes, coupled with technological breakthroughs and innovations, the missile will naturally be able to successfully break through the interception.

Of course, this approach does have limitations.

For example, it is difficult to popularize on a large scale, and only those special missiles can have such a technology, and the cost of a single missile is also very high.

He said, "Ding Hui, I've thought about it carefully, and what you said still doesn't make sense. We can't continue our research in an uncertain direction."

Ding Hui said immediately, "Any research starts from zero, and we are not zero. We can demonstrate and study carefully."

"Why is it not zero? Do you have a way to be sure?"

"There is no way to think about it. I think there are several modes that can be realized, but they need to be studied carefully. Shouldn't they study it because it is difficult?"

"Of course I didn't mean that..."

The two talked again.

This has become the norm in the office.

Both Yuan Zhilin and Ding Hui are excellent researchers of 137 Institutes.

Yuan Zhilin's qualifications are older, and he has also made many research and development contributions, including some well-known missiles, and he is also a direct participant in the research and development. Naturally, the institute is very authoritative.

Ding Hui is still young and has not participated in major projects, but his mathematics level is recognized by the institute, and he is responsible for many calculation tasks.

When the two were talking intensely, Zheng Guofeng walked in from the outside.

His eyes were red.

The others were startled when they saw Zheng Guofeng's appearance, "Professor Zheng, what's wrong with you?"

"What's wrong with you?"

"Pinkeye?"

"...just didn't sleep well." Zheng Guofeng smiled wryly and asked, "Where's Director Pang?"

"Director Pang left today? He went to the third district." Yuan Zhilin said hastily. The third district he mentioned was the third district of the Aerospace Corporation. In fact, it was a professional missile research institute, and it was also the directly superior institution of the 137th Institute.

It was only then that Zheng Guofeng remembered that Pang Sibo had gone to the third district. The leaders of the third district will come to inspect the work next month. They will also synthesize the existing technologies and explore future research work.

Now missile research has entered a bottleneck period.

It can be said that the domestic missile technology has already caught up with the top level in the world. It is very embarrassing to be at this stage. If you want to continue to develop, there is no reference, and it will be very difficult to improve.

Therefore, it is necessary to continuously explore and discuss, and then combine existing technologies for research.

Zheng Guofeng nodded and said to the others, "Everyone gather in the conference room, I have a job to explain."

Soon everyone gathered in the conference room.

Zheng Guofeng stood at the front. He put the documents in his hand on the table, and then said seriously, "Don't talk about the direction anymore. The direction is already there."

"Ding Hui!"

"arrive!"

Ding Hui screamed in shock.

"This is a research institute, so don't be so serious." Zheng Guofeng said with a smile, "You are the best in mathematics in the institute, and you will be responsible for the rest of the work."

"This document, I need all of you to study together, understand, find problems, and demonstrate together. This is the main job."

Ding Hui took the file with curiosity. He opened it and was stunned. "The trajectory correction of the three-dimensional function?"

"Is this a way?" His face was full of disbelief.

"right."

Zheng Guofeng nodded with a smile.

The others were also stunned. Even Ding Hui only had the idea of ​​trajectory correction, but when he thought of the complicated calculations, he knew it would be very difficult to research it.

Now directly see a report on the method of 3D function trajectory correction?

How is this possible?

If it's true, it's amazing!

...

Xihai University, Mason Lab.

Wang Hao took a day off and gave himself a vacation, and then continued to do research. His research was aimed at the NS equation.

The research on the NS equation has once again increased the inspiration value, and normally there should be a direction, but he found that he still couldn't find the direction.

This is also normal.

Before the inspiration value reaches one hundred points, the inspiration value is just a number, and it depends on the thinking in the brain.

He only knows some general connections, but the train of thought is not clear.

"It seems that we still need to continue the research related to the trajectory correction of the curve function."

Wang Hao submitted the previous task for settlement, and then created a new task.

【Task 3】

[Research Project Name: Fixed Trajectory Correction of Random 3D Curve Function (Difficulty: A). 】

[Inspiration value: 0. 】

"Obviously the difficulty has increased a lot, but the judgment of difficulty is still in the range of A-level, and has not risen to the level of S-level."

"It seems that the problem is not too complicated..."

This new research task is very similar to the previous one, the difference is "one-to-one" and "many-to-one".

The previous research was the trajectory correction from fixed function to fixed function, but now it is the trajectory correction from random function to fixed function.

1 to 1, became N to 1.

N to 1, the difficulty has naturally increased, but because it is not an ultra-complex problem of N to N, a solution can still be found.

Although judging the difficulty is not complicated, it is possible to clarify the thinking, but when he devoted himself to the research, Wang Hao found it very complicated.

A lot of numerical values ​​are involved, which involves the problem of mathematical calculation logic.

This kind of mathematical logic is very similar to the NP problem, or it can be said that it is included in it, and the mathematical calculation logic becomes a mess, as if it is a mess that needs to be completely sorted out.

Wang Hao couldn't even figure out where to start. After thinking about it, he decided to consult a professional.

Luo Dayong.

Luo Dayong specializes in complexity theory, and it may be helpful to ask him about this problem.

Wang Hao went to the office of the complex building.

Both Luo Dayong and Zhu Ping were there, and they were the only two in the office.

This has been the norm for a while now.

There were originally six people in the office of the complex building. Wang Hao and Zhang Zhiqiang had been in the Mason Lab for a long time, Yan Jing often went to the physics lab, and Sun Jian liked to run to the lab building of the Faculty of Science. As a result, only Luo Dayong and Zhu Ping were left.

Zhu Ping was drinking milk tea leisurely, when she turned her head and saw Wang Hao, she immediately said, "Professor Wang Da, what a rare visitor!"

Wang Hao shook his head with a smile, "I've been too busy recently."

In fact, he likes to stay in the office of the complex building very much, but because the office is not suitable for research, when he devotes himself to research, he will go to the Mason number laboratory.

As it happens, he has been very busy recently.

Zhu Ping said, "You always don't come, the office is empty, you see, only Luo Dayong and I are left."

Wang Hao said, "Sister Zhu, if you think this place is not good, just go to my laboratory, and you can listen to my lectures every day there. Aren't you worrying about your doctoral dissertation? To increase some basic knowledge, maybe Got an idea."

"What are you talking about?" Zhu Ping asked.

"Mathematics, I'm talking about computational mathematics recently."

"...Forget it." Zhu Ping suddenly lost interest.

In fact, when she heard Wang Hao's lecture, she was still a little interested, but when it involved complicated knowledge content, she immediately lost interest.

Wang Hao continued, "I'm here this time because I have something to look for you."

"Ah?" Zhu Ping was stunned for a moment. She pointed at herself with disbelief on her face, "Looking for me? What can you do with me?"

"I just want to borrow someone from you."

"Borrower, borrower who?"

Wang Hao took it for granted, "Luo Dayong, who else can I borrow?"

Luo Dayong immediately raised his head.

Zhu Ping glanced at Luo Dayong, and said indifferently, "Luo Dayong, borrow it, I don't want to see him!"

"Decree!"

Wang Hao walked over with a smile and said, "Brother Dayong, let's go to the laboratory."

"..."

Luo Dayong glanced at Zhu Ping with a mentally handicapped look, and then Wang Hao went out together.

Zhu Ping was depressed by Luo Dayong's look, and then she suddenly realized that she ran to the door and shouted, "Wang Hao, what are you talking about! What do you have to do with Luo Dayong and me!"

Standing at the elevator entrance, Wang Hao turned his head and asked in doubt, "I didn't say it was related?"

Zhu Ping blushed, and she didn't know if she was angry or for other reasons. She emphasized again, "It doesn't matter to us anyway!"

Wang Hao got on the elevator and gave Luo Dayong a thumbs up.

Luo Dayong sighed, "Zhu Ping!"

He pointed to his head, then shook his head.

Zhang Zhiqiang was going upstairs from another elevator. He was about to give lessons to the students. He came to the office to get textbooks, but when he came in, he found that only Zhu Ping was there.

"Where's Luo Dayong?" He asked a little strangely.

Zhu Ping seemed to be sulking, and she said angrily, "Even Wang Hao has learned badly, so he must have learned from you!"

"What?"

Zhang Zhiqiang touched the top of his head where the hair was obviously thinning, and stood there thinking for a long time, but couldn't figure out what he had done.

...

Luo Dayong is indeed an expert in complexity theory.

He has been engaged in research on np problems. It is difficult to produce results in related research, but as long as they are produced, they must be great achievements.

Even if there are no major achievements recently, his understanding of complexity issues is not comparable to others.

The complexity problem is mainly computational logic.

The complex calculation question of 'n to 1' that Wang Hao wants to ask also involves the logic of calculation.

In this regard, Luo Dayong has studied deeply, and he directly gave a suggestion, "If you are analyzing n-to-one problems, you generally start with 1, because you must find commonality to solve the problem."

"I haven't researched the function curve you mentioned, but the final goal of the modified function curve is the objective function."

"Let me give you an example. It's like releasing many lines from one point. They may be different, but their intersection points are the same."

"That's the commonality."

"Start from the commonality to conduct anti-reasoning, and then study other common features."

Wang Hao was listening very seriously, and he also discussed with Luo Dayong.

Soon a prompt appeared in the system.

[Task 3, inspiration value +6. 】

very good!

Wang Hao's discussion became more active and enthusiastic, because he knew that the direction to solve the complexity problem was correct.

For the next few days, Wang Hao took Luo Dayong to study this problem together. He found that Luo Dayong's research on complexity theory was indeed very in-depth, and he could always give solutions to some problems.

Later, he simply invited Luo Dayong to join the Mason Number Laboratory.

"Wait next semester, the new building built over there will be officially opened, will you take students with you then?"

"Just come to the lab to be a researcher, and you can get a monthly subsidy."

The last sentence convinced Luo Dayong.

Although there are not many subsidies for the laboratory, because it is necessary to bring students, it must be a project. It is impossible to do mathematics and computer research alone like it is now.

With the subsidy for the laboratory and the subsidy for the project, he can not only subsidize the students, but also earn more money.

Luo Dayong thought about it and agreed.

the other side.

The 137 Institute has also done in-depth research on the content written by Wang Hao.

They have determined that the content is correct.

This is enough.

Even Ding Hui didn't fully figure it out from beginning to end, but he knew that this method was no problem.

At the meeting, he concluded with some excitement, "The report presented by Professor Zheng is a brand-new trajectory correction method, which is so exquisite that it can even be converted into code and let the computer do the calculation."

"The only thing that is uncertain now is the deviation value, but I did a substitution calculation and found that the deviation value is very small and completely within the controllable range."

"The missile has a positioning on the target. If the deviation is not large, it can re-lock the target and change the trajectory. In other words, no matter what method we use to change the trajectory, the missile can return to the original trajectory. There is also a Instantly change the trajectory and avoid the opportunity of anti-missile interception!"

"However, it is still difficult to completely transform this method into code. In this regard..."

While Ding Hui was talking excitedly, Pang Sibo suddenly walked in from the door. He had just come back from the third district and came in when he saw a meeting.

No one in the conference room paid any attention to him, and everyone listened to Ding Hui's report.

When Pang Sibo came in, he wanted to talk to Zheng Guofeng, but Zheng Guofeng stretched out his hand to signal him to be quiet.

Depressedly, he found a seat and sat down, and listened to it a few times, and then he didn't quite understand it.

He thought that he would continue to discuss the direction of research and development, but it turned out that Ding Hui was giving a report on converting mathematics into computer code?

wrong!

This is talking about the problem of missile trajectory correction, and is it explaining the specific method?

Pang Sibo's eyes widened suddenly, and he was completely stunned, "Shouldn't we discuss the direction of research and development? How did you get to the specific method of missile trajectory correction?"

"There is such a method?"

"I just went out for a few days? Could it be that I stepped on a node of time and space and traveled to a time point a few years later?"

He even felt a bit like a dream, and twisted his cheek hard.

It hurts!

However, he still couldn't figure out why there was such a big progress after only going out for a few days?

What the hell am I missing!
