Zheng Guofeng is fifty-three years old. He is still in the middle-aged and strong stage, but after all, Jing is a bit older.
For people of this age, 1:30 in the morning is the time when they sleep most soundly.
The cell phone on the table suddenly rang.
As a chief researcher of a confidential scientific research institution, my mobile phone is usually not turned off because there are occasional emergency communications, but because the number is not disclosed to the public, it will not be turned off in the early morning.
The call came in.
If so, it might be a big deal.
Zheng Guofeng suddenly woke up when he heard the phone ringing. He quickly picked up the phone and looked at the person on the caller ID, his face suddenly turned dark.
Liu Rongxing?
There's no way this guy is calling with an urgent problem!
Zheng Guofeng answered the phone with a dark face, scolding Liu Rongxing to death in his heart, and his tone was definitely not good, "What's the matter! Director Liu! Are you disturbing people's dreams?"
Liu Rongxing has a good temper.
He had just been woken up not long ago. Of course he understood what it felt like to be woken up by a phone call. He suppressed a smile and said, "Professor Zheng, you don't know. For your sake, I
But I stayed up until now. 「
"The result of your question has been sent to you through the intranet. You can log in and take a look."
"Okay, that's it, don't put it off until tomorrow morning!"
Liu Rongxing reminded him and put down the phone after speaking.
Zheng Guofeng froze in bed for a long time, and he continued to scold Liu Rongxing in his mind, "Why don't we just tell you the results once we have them, and why do we have to check them on the computer?"
"Are you afraid that you'll be sober all the time and forget about it after listening to it in the evening?"
I didn’t understand much, but I still got up from the bed and turned on the computer. Before logging into the intranet, I found a confidential file sent by Zheng Guofeng. Before I clicked to unlock it,
His eyes suddenly opened.
Yuan Zhilin is more professional than Zheng Guofeng. What I saw was just the title introduction, and I knew the specific content after just a quick glance.
Trajectory correction of eight-dimensional functions!
Detailed calculation method!
"Without the content of mathematical analysis, you can't just use computers to do calculations?"
"Are you out of your mind?"
Yuan Zhilin suddenly became more energetic. I finished reading carelessly from the beginning, and everyone understood that it was not a night. When I realized what I was doing, there was no window.
There was light.
I glanced at the time, knowing that I might have finished reading, so I quickly lay down under the bed again, and ended up falling asleep at all.
I couldn't help but continue to scold Zheng Guofeng secretly, "That man named Liu, if he did it on purpose, I would have just told you this early in the morning. Did he tell you to sleep?"
"It's really missing: Xiaodui!"
It's a new day.
The main research building of Institute 137 became silent again.
In the side office on the first floor, Zhu Ping is sorting out documents. At eighty-seven years old, I am considered older outside the institute, but because my math level is very low, I am outside the institute.
Point cultivated talents.
Zhu Ping is also a representative of the "younger group" outside the institute, or a representative of the "novel group".
There are not many new ideas in the Nianzhong faction. We dare to innovate and explore. In the research direction of missile orbits, we all support the exploration of new orbit change modes, and
Just keep using the old way.
Zhu Ping was also talking to others, "You should find a new method."
"Before the missile is launched, it cannot use various trajectory changes, but the peak period for interception is when it rises and falls until it hits the target."
"In that section, using Luo Dayong ballistics is one method, but Luo Dayong ballistics has no limitations and may be analyzed. Very few conventional missiles can also use that method.
Simple ballistics. 「
"You think you can't use the sideways method to create thrust. It's just that it's difficult to calculate the route..."
I said and shook my head.
Liu Rongxing also left the office. I did not support Zhou Lan's idea, because the method mentioned by Zhu Ping seemed promising.
Of course I know this way is better, but how to do it?
Can you just say it and do it?
I will definitely continue to study Luo Dayong's ballistics, and at least a few orbit-changing modes, coupled with breakthrough innovations in technology, will naturally not allow the missile to successfully break through the interception.
Of course, that approach really has no limitations.
For example, it is difficult to reduce small-scale popularization, and only these ordinary missiles can possess such technology, and the cost of a single missile is also very low.
I said, "Zhu Ping, if you think about it carelessly, what he said still makes sense. You can continue your research in a certain direction."
Zhu Ping immediately said, "Any research ends from zero, and you are still zero. You can't argue or do research."
"Why is it zero? Is there any way to determine it?"
"Is there any way to think about it? Do you think that there are not many models that can be realized? It just requires sloppy research. Is it just because it is not difficult?"
"Of course you mean it..."
The two started talking again.
That's not the norm in the office anymore.
Liu Rongxing and Zhu Ping are both very outstanding researchers at the 137th Institute.
Liu Rongxing is older and has made many R&D contributions, including some very unknown missiles. He is also a direct participant in R&D, so he naturally has no authority.
of.
Zhu Ping is still young and has not participated in too many small projects. However, my mathematics level is recognized by the outside world, and I am responsible for most of the calculation work.
When the two of them were talking calmly, Pang Sibo walked 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 happened to him?"
"Pinkeye?"
"...I didn't sleep well." Yuan Zhilin smiled bitterly and asked, "Where is Director Pang?"
"Director Pang left today? To the Eighth District." Liu Rongxing said quickly. The Eighth Districts I mentioned are from the Eighth District of the Aerospace Group. In fact, they are a professional missile research team.
The hospital is also a directly subordinate institution of the 137th Institute.
Only then did Yuan Zhilin remember that Zhang Zhiqiang had gone to the Eighth District. Last month, the leaders of the Eighth District came to inspect the work. They also wanted to synthesize the existing technologies and explore future research work.
Now missile research has entered a bottleneck period.
It cannot be said that domestic missile technology has not caught up with the world's top level. It is very embarrassing at that stage. If you want to continue to develop, you have no reference. If you want to improve, you will have to
Very difficult.
Therefore, it is necessary to continuously explore and discuss, and then combine it with existing technologies to study.
Zhou Lanyi nodded and said to me, "Everyone, please gather in the conference room. You don't have any work to answer."
Soon everyone gathered in the conference room.
Yuan Zhilin stood at the back. I put the documents in my hands under the table and said seriously, "We are going to discuss the direction again. The direction is not gone yet."
"Zhu Ping!"
"arrive!"
Zhu Ping shouted excitedly.
"That's a research institute, so serious." Pang Sibo said with a smile, "He is the best in mathematics outside the institute, so he will be responsible for the next work."
"You need all of them to study that document together, to understand, find problems, and demonstrate together. That is not the main job."
Zhu Ping took the file with curiosity. I opened it and was stunned. "/Trajectory correction of eight-dimensional functions?"
"Is that a method?" My face was filled with confusion.
"right."
Pang Sibo smiled and nodded.
Others were stunned for a while. Even Zhu Ping only had the idea of trajectory correction, but when I thought of such complicated calculations, I knew it would be very difficult to study it.
Now directly see a method report for eight-dimensional function trajectory correction?
How is that possible?
It must be true, it’s amazing!
Xihai Primary School, Qian Xuesen Laboratory.
Ding Wen took a day off and gave himself a holiday, and then continued his research. My research focused on the NS equation.
The research on the NS equation once again lacked the improvement in inspiration value. Generally speaking, there should be no direction, but I found that I still found the direction.
That's unusual too.
After the inspiration value reaches one hundred points, the inspiration value is just a number, and it still depends on the thoughts in the mind.
I only know some small connections, but the idea is not clear.
"It seems that we still need to continue research related to curve function trajectory correction."
Ding Hui submitted the subsequent tasks for settlement and then created a new task.
【Task 8】
[Research project name: Fixed trajectory correction of random eight-dimensional curve functions [(Difficulty: A)]. 】
[Inspiration value: 0. 】
"Obviously the difficulty level has increased very little, but the difficulty level is still in the level range, and has not gone down to S level."
"It seems that the problem is not too simple..."
The new research task was very similar to the later ones, the difference was "one-on-one" and "less pairs-".
The subsequent research was the trajectory correction from a fixed function to a fixed function, but now it is a trajectory correction from a random function to a fixed function.
1 to 1 becomes N to 1.
Naturally, the difficulty of N vs. 1 has not increased, but because it is a super simple problem of N vs. 1, a solution can still be found.
Although it was judged as easy under the difficulty level and it was impossible to clarify the ideas, when he devoted himself to research, Ding Hui found that it was very simple.
There are very few numerical values involved, and it involves issues of mathematical calculation logic.
That kind of mathematical logic is very similar to the NP problem, or it cannot be said to be included in it. The mathematical calculation logic becomes messy, like a mess.
All sorted out.
Zhou Lan even found out where they were from. After thinking about it, I decided to consult a professional.
Zheng Guofeng.
Zheng Guofeng specializes in simplicity theory. When faced with that problem, asking me may not be helpful.
Zhou Lan went to the complex office.
Zheng Guofeng and Wang Hao are both here, and there are only two of us in the office.
That's been the norm lately.
The office in the complex building didn't last long. Zhou Lan and Mason had been in Qian Xuesen's laboratory for a long time. Yan Jing often went to the physics laboratory. Sun Jian hated going to the School of Science for experiments.
He ran away, and only Zhou Lanyi and Wang Hao were left.
Wang Hao was drinking milk tea leisurely. When he turned around and saw Ding Hui, he suddenly said, "Little Professor Wang, you are such a rare visitor!"
Ding Hui smiled and shook his head, "I've been too busy recently."
In fact, I hate staying in the office in the complex building, but because the office is suitable for research, when I devote myself to research, I will go to Qian Xuesen's laboratory.
As it happens, I've been very busy lately.
Zhou Landao said, "He always comes and the office is empty. He sees that you and Zheng Guofeng are the only ones left."
Ding Hui said, "Sister Zhu, if he thinks it is good, he can just go to your laboratory. He can listen to your lectures here every day. He is worried about his doctoral dissertation."
? Add some basic knowledge and you may have no idea. 「
"What was he talking about?" Wang Hao asked.
"Mathematics, I'm talking about computational mathematics recently."
",...Forget it." Zhou Lan suddenly lost interest.
In fact, when you heard Ding Hui talk about the lecture, you were not interested at all, but when it involved simple knowledge content, you immediately became interested.
Ding Hui continued, "That time you came to see him for nothing."
"Ah?" Wang Hao was stunned for a moment. You pointed at yourself with a look of disbelief on your face, "Looking for you? Is there nothing wrong with him looking for you?"
"We never wanted to borrow someone from him."
"For a long time, who can I borrow from?"
Ding Hui said matter-of-factly, "Zheng Guofeng, who else can I borrow?"
Zheng Guofeng raised his head when he heard this.
Wang Hao glanced at Zheng Guofeng and said with concern, "Zheng Guofeng, borrow it, you really want to see me!"
"Got the order!"
Ding Hui smiled and walked over and said, "Brother Xiaoyong, let's go to the laboratory."
Zheng Guofeng glanced at Wang Hao with a look that looked at Qiang Zhi, and then Ding Hui went out together.
Wang Hao was very depressed when Zheng Guofeng saw him. He suddenly realized what he was doing and ran to the door and shouted, "Ding Hui, what did he say! He has nothing to do with you looking for Zheng Guofeng."
Ding Hui stood at the elevator entrance and turned around and asked doubtfully, "You also said it's okay?"
Wang Hao's face turned red, and he knew it was someone else who was angry. You said softly, "Anyway, you have a relationship!"
Ding Hui sat down in the elevator and raised his little thumb towards Zheng Guofeng.
Zheng Guofeng sighed, "Zhou Lan!"
I pointed to my head and shook my head.
Mason was coming downstairs from another elevator, and I was about to go to the students' get out of class. I came to the office to get textbooks, but when I stepped back, I found that only Wang Hao was not there.
"Where is Zhou Lanyi?" I asked without any surprise.
Wang Hao seemed to be sulking, and you said angrily, "Even Ding Hui learned it badly, if you learned it from him!"
"What?"
Zhou Lanyi touched the top of her head where her hair was obviously dense, and stood there thinking for a long time, trying to figure out what she had done.
Zheng Guofeng is indeed an expert in simplicity theory.
I have been engaged in research on np problems. It is difficult to produce results in related research, but as long as results are produced, they will be small results.
Even if there are no small achievements recently, my understanding of simplicity issues is comparable to others.
The issue of simplicity is not primarily about computational logic.
The simple calculation question of "n versus 1" that Ding Hui wants to ask also involves the logic of calculation.
In that aspect, Zhou Lanyi studied very deeply, and I directly gave a suggestion, "It must be to analyze the n-to-one problem. We always have to start from 1, because to solve
The questions must find commonalities. 「
"Have you studied the function curves he mentioned? But the ultimate goal of correcting function curves is the objective function."
"If you give him an example, it's like a few lines are drawn from a point. We may be the same, but our intersection is the same."
"That's not common."
"Start from commonalities and then reason backwards, and then study the characteristics that we have in common."
Ding Hui listened very carefully, and Zheng Guofeng and I also discussed it together.
Very slowly, a flute prompt appeared in the system.
[Task eight, inspiration value +6.]
very good!
Ding Hui's discussion became more positive and cold, because I knew that the direction to solve the simplicity problem was in the right direction.
For the next few days, Zhou Lan took Zheng Guofeng to study the issue together. I found that Zhou Lanyi was indeed very in-depth in their research on sexual theory.
Questions always provide solutions.
Come and simply invite Zheng Guofeng to join Zhou Lanyi's laboratory.
"The new building built here will be officially opened next semester. Will he also take care of students by then?"
"Just come to the laboratory and work as a researcher, and you won't get a monthly subsidy."
The first sentence convinced Zheng Guofeng.
Although the subsidy for the laboratory is not small, because you have to take care of students, if you are doing a project, it may be like now, just doing mathematics and computer research alone.
Without the laboratory subsidy, plus the project subsidy, I can not only provide subsidies to students, but also make less money.
Zheng Guofeng thought about it and agreed to come up.
the other side.
Institute 137 has not done in-depth research on the content written by Zhou Lan.
We have not yet determined that the content is correct.
That's enough.
Even Zhou Lan didn't get them completely from beginning to end, but I knew there was something wrong with that method.
After the meeting, I concluded without excitement, "The report that Professor Zheng presented is a brand-new trajectory correction method. It is so exquisite that it cannot even be transformed into
code and let the computer do the calculations. 「
"Now it is determined that it is only the deviation value, but the substitution calculation you did found that the deviation value is very large and completely within the controllable range. "
"The missile has no position on the target. If the deviation is small, it cannot re-lock the target and change the trajectory. In other words, it doesn't matter what method you use to change the trajectory:
, the missile can return to its original trajectory, and there is no chance of changing its trajectory instantly to avoid anti-missile interception! 「
"Yes, it's not difficult to completely convert that method into code. In that regard..."
When Zhu Ping was talking excitedly, Zhang Zhiqiang suddenly walked back from the door. I had just come back from District 8, so I backed out when I saw that there was no meeting.
Someone in the conference room paid attention to me, and everyone listened to Zhu Ping's report.
Zhang Zhiqiang wanted to talk to Yuan Zhilin when he came back, but Zhou Lanyi stretched out his hand to signal me to be quiet.
I found a seat and sat down depressedly, and listened to it for a few times, but then I didn’t understand it at all.
I thought they would continue to discuss research and development directions, but it turned out that Zhu Ping was giving a report on converting mathematics into computer code?
is true!
That's talking about missile trajectory correction, and is it explaining the specific method?
Zhou Lanyi stared fiercely: My eyes were small, and I was completely stunned, "Should we discuss the direction of research and development? How come we don't know the missile's trajectory correction method?"
"Jingran doesn't have that method?"
"You were only out for a few days? Could it be that you stepped on a time and space node and traveled to a time a few years ago?"
I didn't even feel like I was dreaming, and I pinched my cheek hard.
It hurts!
However, I still thought it made sense. I was only out for a few days, so why didn’t I withdraw from the exhibition in such a small way?
What did you miss!
