Zheng Guofeng is fifty-three years old, and he is still in the stage of middle age and strength, but Bi Jing is a little old.

At this age, half past one in the morning is the time to sleep the 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 is occasionally emergency communication, but because the number is not public, it will not be in the early morning

The call came in.

If there is, it could be a big deal.

When Zheng Guofeng heard the sound of the phone, he woke up with a wit, he quickly picked up the phone, looked at the caller ID, and suddenly his face turned a little dark.

Liu Rongxing?

This guy called, there could be no urgent problem at all!

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

Liu Rongxing has a good temper.

He had just been called up not long ago, and of course he understood what it was like to be woken up by the phone, so he held back a smile and said, "Professor Zheng, you don't know, I'm for your business,

But I stayed up all night until now. 「

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

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

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

Zheng Guofeng was stunned in bed for a long time, and he continued to scold Liu Rongxing in his heart, "Wouldn't it be good to say the results when you have them, and you still have to go to the computer to check it?"

"I'm afraid you're always sober, and you'll forget it after listening to it late and getting down early?"

I didn't understand anything, but I still got up from under the bed and turned on the computer, and before logging in to the intranet, I found that Zheng Guofeng had passed a confidential document.

Eyes suddenly departed.

Yuan Zhilin is more professional than Zheng Guofeng, but what I see is only the title introduction, and I can know the specific content by browsing it at a glance.

Trajectory correction for eight-dimensional functions!

Detailed calculation method!

"With the content of mathematical analysis removed, can't you directly use a computer to do the calculation?"

"You're out of the picture, are you?"

Yuan Zhilin suddenly became more energetic, I looked sloppily from the beginning, and we understood from it, and it was not a late night, and when I reacted, there was no room in the window

There was a bright light.

I looked at the time, knew that I might have finished it, and quickly lay down under the bed again, and ended up falling asleep at all.

I had to continue to scold Zheng Guofeng, "That surnamed Liu, if it was deliberate, it would be good to pass it on to you in the morning, and let you sleep?"

"It's really lacking: Xiaode!"

It's a new day.

The main research building of the 137th Institute became silent again.

In the side office on the first floor, Zhu Ping is sorting out documents, I am eighty-seven years old, and I am older outside the office, but because the level of mathematics is very low, I am outside the office

Point of cultivated talents.

Zhu Ping is also a representative of the "old school" outside the institute, or a representative of the "novel school".

There are few new ideas in the year, we dare to innovate and explore, and we all support the exploration of new orbit change modes under the research direction of missile orbits

It is to continue to follow the old way.

Zhu Ping was also talking to the others, "You should find a new way."

"Before the missile is launched, it cannot use various orbit change methods, but it is the low peak period of interception when it hits the target."

"In that section, the use of Luo Dayong's trajectory is a method, but Luo Dayong's trajectory has no limitations, and it may be analyzed, and very few conventional missiles can also use that

Simple ballistics. 「

"You don't think you can use the side to create thrust, but it's hard to calculate the route......

I said and shook my head.

Liu Rongxing also walked out of the office, and I did not support Zhou Lan's idea, because the method Zhu Ping said felt like hope.

Of course I know it's better, but how do you go about it?

Can you just say it's done?

We will definitely continue to study Luo Dayong's ballistics, study a few orbit change modes, and make breakthroughs and innovations in technology, so naturally we will not be able to allow the missile to successfully break through and intercept.

Of course, there are no limits to that approach.

For example, it is difficult to retreat from small-scale popularization, and only these ordinary missiles can have such technology, and the cost of a single missile is very low.

I said, "Zhu Ping, you thought about it sloppily, what he said still makes sense, you can continue to study in a certain direction."

Zhu Ping suddenly said, "Any research ends from scratch, and you are still zero, you can't argue, you can't go to research."

"How can it be zero? Don't know how to do it? 「

"Is there a way not to think, do you think that there are not several models that can be realized, but it just needs sloppy research, is it because it is not difficult to study?"

"Of course you mean that、...

The two talked again.

That's not the norm in the office.

Liu Rongxing and Zhu Ping are both very good researchers at 137 institutes.

Liu Rongxing is older, and he has also made a few R&D contributions, including some very little-known missiles, and he is also a direct participant in R&D

Target.

Zhu Ping is still young, has she been involved too much; It's a small project, but my math level is recognized outside the world, and I am responsible for the calculations.

When the two were talking calmly, Pang Sibo stepped back from inside.

My eyes were red.

I was shocked when I saw Yuan Zhilin's appearance for a long time, "Professor Zheng, what's wrong with him?"

"What's wrong with him?"

"Pinkeye?"

「…… Not to have a good night's sleep. Yuan Zhilin smiled bitterly and asked, "What about Director Pang?"

"Director Pang left today? Went to the 8th district. "Liu Rongxing hurriedly said, the eight districts I am talking about are from the eight districts of the aerospace group, in fact, they are professional missile researchers

It is also a direct subordinate institution of 137 institutes.

Yuan Zhilin remembered that Zhang Zhiqiang had gone to District 8, and the leaders of District 8 had come to inspect the work last month, and they were also to synthesize the existing technology and explore future research work

At present, missile research has retreated into a bottleneck period.

Domestic missile technology, it cannot be said, has not yet caught up with the world's top level, at that stage is very embarrassing, if you want to continue to develop, there is no reference, and then improve it

It's very difficult.

Therefore, it is necessary to explore and discuss it in a decisive way, and then combine it with the technology that is no longer available.

Zhou Lanyi nodded and said to him for a long time, "; The small family gathers in the conference room, and you have no work to explain. 「

It was very slow, so no one gathered in the conference room.

Yuan Zhilin stood at the back, I put the documents outside my hand under the table, and said seriously, "What direction is going to be discussed again, the direction is not gone."

"Zhu Ping!"

"Here!"

Zhu Ping shouted excitedly.

"It's a research institute outside that, and it's so serious." Pang Sibo laughed, "He is the best in mathematics outside the school, and he will be responsible for the next job."

"That document, you need none of them to study it together, to understand, to find problems, to demonstrate, that's not the main job."

Zhu Ping took the file with curiosity, I opened it and looked at it, and I was stunned, "/Trajectory correction of eight-dimensional functions?"

"Is that a way?" My face was full of wonder.

"Yes."

Ponsberg smiled and nodded.

I was stunned for a long time, even Zhu Ping only had the idea of trajectory correction, but when I thought of this complicated calculation, I knew that it was very easy to study it.

Now you can see a report on the method of correction of the trajectory of the eight-dimensional function?

How is that possible?

It must be true, it's amazing!

Xihai Primary School, Qian Xuesen Laboratory.

Ding Zhu took a day off, and then continued to do research, and my research focused on the NS equation.

The study of the NS equation has once again lost the inspiration value, and there should be no direction in the anomaly, but I found that I still found the direction.

That's anomalous too.

After the inspiration value reaches 100 points, the inspiration value is just a number, and it depends on the thinking in the head.

I only know a few small connections, but the idea is clear.

"It seems that we should continue to study the trajectory correction of curve functions."

Ding Hui submitted the following tasks for settlement, and then created new tasks.

【Task 8】

[Title of Research Project: Fixed Trajectory Correction of Stochastic Eight-Dimensional Curve Functions [(Difficulty: A)] 】

[Inspiration value: 0.] 】

"Obviously, the difficulty has increased very little, but the difficulty is still in the range of levels, and there is a degree of not rising to S level."

"Doesn't it seem too simple..."

The new research task is very similar to the one after that, but the difference is that "one-to-one" and "less pair-".

Later studies were on trajectory correction from fixed functions to fixed functions, and now it is trajectory correction from random functions to fixed functions.

1 to 1 becomes N to 1.

N to 1, the difficulty has not increased, but because it is a super simple problem of N pairs, a solution can still be found.

Although it is easy to judge under the difficulty and cannot clear the mind, when he invests in the research, Ding Hui finds that it is very simple.

There are very few numerical values involved, and it involves the problem of mathematical calculation logic.

That kind of mathematical logic is very similar to the NP problem, or it can't be said to be included in it, and the computational logic of mathematics becomes a mess, as if it were a mess

Sort it all out.

Zhou Lan even looked for where to come from, I thought about it or decided to consult a professional.

Zheng Guofeng.

Zheng Guofeng specializes in simplicity theory, and when faced with that question, it may not be helpful to ask me.

Zhou Lan went to the office of the complex building.

Zheng Guofeng and Wang Hao are there, and there are only two of us in the office.

That's been the norm for a while now.

The office of the comprehensive building was not eight long, Zhou Lan and Mason Shu had been in Qian Xuesen's laboratory for a long time, Yan Jing often went to the physics laboratory, and Sun Jian was disgusted to go to the School of Science to experiment

ran, and as a result, there were only two people left, Zhou Lanyi and Wang Hao.

Wang Hao was drinking milk leisurely, and when he turned his head and saw Ding Hui, he suddenly said, "Wang; Little professor, what a rarity! 「

Ding Hui smiled and shook his head, "I've been too busy lately."

Actually, I hate staying in the office of the comprehensive building, but because the office is suitable for research, when I devote myself to research, I will go to Qian Xuesen's laboratory.

It just so happens that I've been busy lately.

Zhou Lan said, "He always comes, the office is empty, he sees, there are only you and Zheng Guofeng left."

Ding Hui said, "Sister Zhu, if he thinks it's good, just go to your laboratory, and he can listen to your lectures every day here, he is worried about the doctor's theory."

Is it? Add some basics and maybe run out of ideas. 「

"What did he say?" Wang Hao asked.

"Math, I've been talking about computational math lately."

「，…… Forget it. Zhou Lan suddenly lost interest.

In fact, when you hear Ding Hui give a lecture, you are still not interested, but when it comes to simple knowledge content, you are immediately interested.

Ding Hui continued, "You didn't have anything to do with him that time.

"Huh?" Wang Hao was stunned for a moment, you pointed at yourself with your finger, your face was full of disbelief, "Looking for you? Is it okay for him to find you? 「

"We always wanted to borrow someone from him."

"Borrow for a long time, who to borrow?"

Ding Hui said as a matter of course, "Zheng Guofeng, who else can I borrow?"

Zheng Guofeng raised his head in a hurry.

Wang Hao glanced at Zheng Guofeng, and said with concern, "Zheng Guofeng, borrow it, you just want to see me!"

"Order!"

Ding Hui walked over with a smile and said, "; Brother Xiaoyong, let's go, go to the laboratory. 「

Zheng Guofeng glanced at Wang Hao with Qiang Zhi's eyes, and went out with Ding Hui in front of him.

Wang Hao was very depressed by Zheng Guofeng, and suddenly reacted, ran to the door and shouted, "Ding Hui, what did he say!" He has nothing to do with you when he finds Zheng Guofeng

Ding Hui stood at the elevator entrance and turned his head and wondered, "You also said it's okay?"

Wang Hao's face turned red, and he also knew that he was angry or because of himself, and you said weakly, "Anyway, you have a relationship!"

Ding Hui sat down in the elevator and gave Zheng Guofeng a thumbs up.

Zheng Guofeng sighed, "Zhou Lan!"

I pointed to my head and shook my head.

Mason Shu was going downstairs from another elevator, and I was about to go to the end of class for the students, and I came to the office to get the textbooks, but when I retreated, I found that only Wang Hao was there.

"Where's Zhou Lanyi?" I asked in no surprise.

Wang Hao seems to be sulking, and you are angry and said, "Even Ding Hui has learned badly, if you learn from him!"

"What?"

Zhou Lanyi touched the top of his head with obviously dense hair, and stood in place and thought about it for a long time, figuring out what he had done.

Zheng Guofeng is indeed an expert in the theory of simplicity.

I've been working on NP issues for a long time, and it's hard to produce results from related research, but as long as they do, they are small.

Even if there have been no small achievements recently, my understanding of simplicity is comparable to that of others.

The problem of simplicity is not primarily computational logic.

The simple calculation problem of "n to 1" that Ding Hui wants to ask also involves the logical problem of calculation.

In that regard, Zhou Lanyi has studied very deeply, and I directly gave a suggestion, "It must be the analysis of the problem of n to one, and we must start with 1 because we solve it."

Questions must find commonalities. 「

"Have you studied the curves of functions and the like he mentioned, but the ultimate goal of correcting the curves of functions is the objective function."

"You give him an example, it's like a few lines are released from -- point, we may be the same, but our intersection is the same."

"That's not the commonality."

"Starting from the commonality, we will degenerate anti-reasoning, and then study the common characteristics of the other."

Ding Hui listened very carefully, and I also discussed it with Zheng Guofeng.

Very slowly, a flute prompt appears in the system.

[Quest 8, Inspiration +6.]

Very good!

Ding Hui's discussion became more positive and cold, because I knew that the solution to the problem of simplicity was in the right direction.

For several days in a row, Zhou Landu pulled Zheng Guofeng to study that problem together, and I found that Zhou Lanyi did a very in-depth study of the theory of sexuality, and there were no more

The problem always gives a solution.

Come and simply invite Zheng Guofeng to join Zhou Lanyi's laboratory.

"Last semester, the new building built here will be officially opened, and he will also bring students at that time, right?"

"Just come to the laboratory as a researcher, and you can still get a monthly subsidy."

The first sentence persuaded Zheng Guofeng.

Although the subsidy for the laboratory is not small, because you have to take students, if you want to do a project, it may be like now, just one person doing mathematical computer research

Without the subsidy of the laboratory, plus the subsidy for the project, I can only subsidize the students, and I can make less money.

Zheng Guofeng thought about it and agreed to come up.

The other side.

The 137 Institute has not done an in-depth study of what Zhou Lan wrote.

We're not sure it's correct.

That's enough.

Even Zhou Lan didn't completely follow them from beginning to end, but I knew that there was something wrong with that method.

At the end of the meeting, I concluded with some excitement, "The report that Professor Zheng presented is a completely new trajectory correction method, which is so superb that it cannot even be transformed

code and let the computer do the calculations. 「

"Now it's only the deviation that is determined, but you did the substitution calculation, and it turned out that the deviation value is very large, and it is completely controllable."

"If the missile is not positioned on the target, and the deviation is small, it cannot re-lock the target and change the trajectory, in other words, no matter what method you use to change the trajectory:

, the missiles can return to their original trajectory, and there is no chance to change the trajectory in an instant and avoid anti-missile interception! 「

"Yes, it's not difficult to completely convert that method into code, that aspect ......."

When Zhu Ping was talking excitedly, Zhang Zhiqiang suddenly walked back from the door, I just came back from District 8, and I retreated when I saw that there was no meeting.

Someone in the conference room paid attention to me, and the little family listened to Zhu Ping's report.

Zhang Zhiqiang retreated and wanted to talk to Yuan Zhilin about things, but Zhou Lanyi stretched out his hand and motioned for me to be quiet.

I depressedly found a place to sit up, and listened to it a few times, but I didn't understand it too much.

I thought it would continue to discuss the direction of R&D, but Zhu Ping was doing a report on translating mathematics into computer code?

That's right!

That's talking about the problem of trajectory correction of missiles, and it's about explaining the specific method?

Zhou Lanyi glared fiercely: My eyes were small, and I was completely stunned, "Should we discuss the direction of research and development?" How did the county get the trajectory correction method of the missile? 「

"Jingran doesn't have that way?"

"You've only been out for a few days? Could it be that you stepped on a space-time node and traveled to a point in time a few years ago? 「

I didn't even feel like I was dreaming, and I twisted my cheek hard.

It hurts!

However, I still figured it out, just going out for a few days, why didn't there be such a small retreat?

What the hell are you missing!
