Chapter 192: Is there such a method? What did I miss?
Zheng Guofeng is fifty-three years old. He is still in the middle-aged and strong stage, but he is somewhat older after all.
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, there will be no calls in the early morning.
If so, it might be a big deal.
When Zheng Guofeng heard the ringing of the phone, he suddenly woke up. He quickly picked up the phone and looked at the person on the caller ID. His face suddenly turned dark.
Liu Rongxing?
There is no way this guy is calling with an urgent problem!
Zheng Guofeng answered the phone with a dark face, scolding 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 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. I stayed up all night for your sake."
"The result of your question is available. I have sent it 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 stayed 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 I'm old and confused and will 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 into 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 saw was not just the title introduction, but he knew the specific content after a brief glance.
Trajectory correction of three-dimensional functions!
Detailed calculation method!
"Without the content of mathematical analysis, can we directly use computers to do calculations?"
"Are you feeling a bit divine?"
Zheng Guofeng suddenly became extremely energetic. He started to look at it carefully from the beginning and understood it carefully. It lasted all night. When he realized what he was doing, light was already shining through the window.
He glanced at the time and knew that he couldn't finish it. He quickly lay on the bed again, but he couldn't fall asleep at all.
He couldn't help but continue to scold Liu Rongxing secretly, "This person named Liu must have done it on purpose. Couldn't he just pass it to me so early in the morning and not let me sleep?"
"What a lack of virtue!"
…
It's a new day.
The main research building of Institute 137 became lively again.
In the side office on the first floor, Ding Hui is sorting documents. He is in his thirties and is relatively young in the institute, but because of his high level of mathematics, he is a key talent cultivated by the institute.
Ding Hui is also the representative of the ‘younger faction’ in the institute, or the representative of the ‘novel faction’.
The younger generation will have many new ideas, and they dare to innovate and explore. Regarding the research direction of missile tracks, they all support the exploration of new orbit change modes, rather than continuing to use the old methods.
Ding Hui was also talking to others, "We should find a new method."
"After the missile is launched, it can use various orbit changes, but the peak period of interception is when it falls to hit the target."
"In this section, using Qian Xuesen's ballistics is one method, but Qian Xuesen's ballistics has limitations and may be analyzed. Many conventional missiles cannot adopt such complex trajectories."
"I think we can use a sideways method to create thrust, but it's 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 mentioned by Ding Hui seemed to have no hope.
Of course he knows that way is better, but how to do it?
Can't we just talk and not do it?
If we continue to study Qian Xuesen's ballistics and develop several more orbit-changing modes, coupled with technological breakthroughs and innovations, we can naturally allow the missile to successfully break through interception.
Of course, this approach does have limitations.
For example, it is difficult to popularize it on a large scale. Only special missiles can have such technology, and the cost of a single missile is also very high.
He said, "Ding Hui, I thought about it carefully and what you said still doesn't make sense. We can't continue research in an uncertain direction."
Ding Hui immediately said, "Any research starts from scratch, and we are not zero yet. We can demonstrate it and study it carefully."
"Why isn't it zero? Do you have a sure way?"
"There is no way to think about it. I think there are several models that can be achieved, but it requires careful study. Shouldn't we not study it because it is difficult?"
"Of course I didn't mean that..."
The two started talking again.
This has become the norm in the office.
Yuan Zhilin and Ding Hui are both very outstanding researchers at the 137th Institute.
Yuan Zhilin is older and has made many research and development contributions, including some famous missiles. He is also a direct participant in research and development, so he is naturally very authoritative in the institute.
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 fiercely, Zheng Guofeng walked in from outside.
His eyes were red.
Others were shocked when they saw Zheng Guofeng's appearance, "Professor Zheng, what's wrong with you?"
"What's wrong with you?"
"Pinkeye?"
"...I just didn't sleep well." Zheng Guofeng smiled bitterly and asked, "Where is Director Pang?"
"Director Pang left today? He went to the third district." Yuan Zhilin said quickly. The third district he mentioned was the third district of the Aerospace Group. In fact, it was a professional missile research institute and the direct superior organization of the 137th Institute.
Only then did Zheng Guofeng remember that Pang Sibo had gone to the third district. Next month, the leaders of the third district would come to inspect the work. They would also synthesize existing technologies and explore future research work.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Now missile research has entered a bottleneck period.
It can be said that domestic missile technology has caught up with the world's top level. It is very embarrassing at this stage. There is no reference for continued development, and it will be very difficult to improve further.
Therefore, continuous exploration and discussion are needed, and then combined with existing technologies to study.
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 hands on the table and then said seriously, "Don't discuss the direction anymore. The direction is already there."
"Ding Hui!"
"arrive!"
Ding Hui shouted excitedly.
"This is a research institute, so there is no need to 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 next work."
"I need all of you to study this document together, understand it together, find problems, and demonstrate it. This is the main job."
Ding Hui took the file with curiosity. He opened it and was stunned. "Trajectory correction of three-dimensional functions?"
"Is this a method?" His face was full of disbelief.
"right."
Zheng Guofeng smiled and nodded.
Others were immediately stunned. Even Ding Hui only had the idea of trajectory correction, but when he thought of the complicated calculations, he knew that it would be difficult to study it.
Now directly see a method report on three-dimensional function trajectory correction?
How is this possible?
If it's true, it's amazing!
…
Sokai University, Mason Number Laboratory.
Wang Hao took a day off and gave himself a holiday, and then continued his research. His research focused on NS equations.
The research on the NS equation once again had an increase in inspiration value. 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 100 points, the inspiration value is just a number, relying on the thoughts and ideas in the mind.
He only knew some rough connections, but his ideas were not clear.
"It seems that we still need to continue research related to curve function trajectory correction."
Wang Hao submitted the previous task for settlement, and then created a new task.
【Task 3】
[Research project name: Fixed trajectory correction of random three-dimensional curve functions (Difficulty: A).]
[Inspiration value: 0.]
"Obviously the difficulty has increased a lot, but the difficulty is still in the A-level range and has not risen to S-level."
"It seems that the problem is not too complicated..."
This new research task is very similar to the previous one, the difference lies in "one-to-one" and "many-to-one".
The previous research was about 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 became N to 1.
N vs. 1, the difficulty will naturally increase, but because it is not a super complex problem of N vs. N, a solution can still be found.
Although it was not complicated in terms of difficulty and it was possible to clarify the ideas, when he devoted himself to research, Wang Hao found that it was very complicated.
It involves a lot of numerical values and involves mathematical calculation logic issues.
This kind of mathematical logic is very similar to the NP problem, or it can be said to be included in it. The mathematical calculation logic becomes messy, just like 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. When faced with this problem, it may be helpful to ask him.
Wang Hao went to the complex office.
Luo Dayong and Zhu Ping are both there, and there are only two of them in the office.
This has been the norm recently.
There were originally six people in the office in the complex building. Wang Hao and Zhang Zhiqiang had been working in the Mason Mathematics Laboratory for a long time, Yan Jing often went to the physics laboratory, and Sun Jian liked to go to the laboratory building of the School of Science. As a result, only Luo Dayong and Zhu Ping were left.
Zhu Ping was drinking milk tea leisurely. When she turned around and saw Wang Hao, she suddenly said, "Professor Wang, you are such a rare guest!"
Wang Hao smiled and shook his head, "I've been too busy recently."
In fact, he likes to stay in the office in the complex building, but because the office is not suitable for research, when he devotes himself to research, he will go to the Mason Number Laboratory.
It just so happens that he has been very busy recently.
Zhu Ping said, "You always don't come. The office is empty. Look, only Luo Dayong and I are left."
Wang Haodao, "Sister Zhu, if you think this place is not good, just go to my laboratory. You can listen to my lectures there every day. Aren't you worried about your doctoral thesis? Add some basic knowledge, maybe
I have 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, she was a little interested when she heard Wang Hao's lecture, but she lost interest immediately when it involved complex knowledge content.
Wang Hao continued, "I came here this time to see you for something."
"Ah?" Zhu Ping was stunned. She pointed at herself with a look of disbelief, "Looking for me? What can you do if you look for me?"
"I just want to borrow someone from you."
"Borrowing someone, who?"
Wang Hao said matter-of-factly, "Luo Dayong, who else can I borrow?"
Luo Dayong immediately raised his head after hearing this.
Zhu Ping glanced at Luo Dayong and said nonchalantly, "Luo Dayong, let's borrow it, I don't want to see him!"
"Got the order!"
Wang Hao smiled and walked over and said, "Brother Dayong, let's go to the laboratory."
"..."
Luo Dayong glanced at Zhu Ping with a look that looked retarded, and then Wang Hao went out together.
Zhu Ping was very depressed when Luo Dayong looked at her. Then she suddenly realized what she was doing and ran to the door and shouted, "Wang Hao, what are you talking about! What relationship do you have with Luo Dayong and me?"
Wang Hao stood at the elevator entrance and turned around and asked doubtfully, "I didn't say it didn't matter, did it?"
This chapter is not over yet, please click on the next page to continue reading! Zhu Ping's face turned red, and she didn't know whether she was angry or for other reasons. She emphasized again, "Anyway, we don't have anything to do with it!"
Wang Hao got on the elevator and gave Luo Dayong a thumbs up.
Luo Dayong sighed, "Zhu Ping!"
He pointed to his head and then shook his head.
Zhang Zhiqiang was going upstairs from another elevator. He was preparing to teach students. He came to the office to get textbooks, but when he came in, he found that Zhu Ping was the only one there.
"Where is Luo Dayong?" he asked a little strangely.
Zhu Ping seemed to be sulking, and she said angrily, "Even Wang Hao learned it badly, I must have learned it from you!"
"What?"
Zhang Zhiqiang touched the top of his head where his hair was obviously sparse, and stood there thinking for a long time, unable to 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 there are results, it will definitely be a big result.
Even if he has not achieved great results recently, his understanding of complex issues is unmatched by others.
The most important issue of complexity is computational logic.
The complex calculation problem of 'n versus 1' that Wang Hao wants to ask also involves the logic of calculation.
Luo Dayong has done in-depth research on this aspect, and he directly gave a suggestion, "If you are analyzing an n-to-one problem, you should generally start from 1, because you must find commonalities to solve the problem."
"I haven't studied the function curves you mentioned, but the ultimate goal of correcting the function curves 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 commonalities and conduct counter-inferences, and then study other common characteristics."
Wang Hao listened very carefully, and he also discussed with Luo Dayong.
Soon a prompt appeared in the system.
[Task three, inspiration value 6.]
very good!
Wang Hao's discussions became more active and enthusiastic because he knew that the direction to solve complex problems was in the right direction.
For the next few days, Wang Hao took Luo Dayong to study this problem together. He found that Luo Dayong had indeed done in-depth research on complexity theory and could always provide solutions to some problems.
Later, he simply invited Luo Dayong to join the Mason Mathematics Laboratory.
"The new building built over there will be officially opened next semester. Will you take care of students by then?"
"Just come to the laboratory and work as a researcher, and you can get a monthly subsidy."
The last sentence convinced Luo Dayong.
Although the subsidy for the laboratory is not large, because I have to take care of students, I must be doing projects. It is impossible to just do mathematics and computer research as I am now.
With laboratory subsidies and project funding subsidies, he can not only provide subsidies to students, but also make more money.
Luo Dayong thought about it and agreed.
the other side.
Institute 137 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 understand it 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. It is so exquisite that it can even be converted into code and let a computer do the calculations."
"What is uncertain now is only 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 position 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, and there is a time
Change the trajectory instantly and avoid the chance of anti-missile interception!"
"However, it is still difficult to completely transform this method into code. In this regard..."
When Ding Hui was talking excitedly, Pang Sibo suddenly walked in from outside the door. He had just returned from District 3 and came in when he saw a meeting.
No one in the conference room paid attention to him, everyone listened to Ding Hui's report.
Pang Sibo came in and wanted to talk to Zheng Guofeng, but Zheng Guofeng stretched out his hand to signal him to quiet down.
He found a seat and sat down depressedly, and listened for a few times, but then he didn't quite understand it.
He thought they would continue to discuss research and development directions, but it turned out that Ding Hui was giving a report on converting mathematics into computer code?
wrong!
This is talking about 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 come we are specific about the missile's trajectory correction method?"
"Is there such a method?"
"I was only out for a few days? Could it be that I stepped on a time and space node and traveled to a point in time a few years later?"
He even felt a bit like he was dreaming, and he pinched his cheek hard.
It hurts!
However, he still couldn't figure out why there was so much progress after just a few days out.
