Security Bureau.
The moment she saw the word “Security Bureau”, Yang Baoyi almost fainted!
Why is it here? !
Doesn’t the Security Bureau handle ordinary cases?
Who is Meng Fu? !
She has done a lot of dirty things in her life. She has threatened people countless times, some of them even worse than Jiang Xinchen. .
When she threatened Jiang Xinchen, she only called two people at random, because she really didn't take Jiang Xinchen seriously.
This was the first time she was threatened, and it was a threat to the lives of her entire family.
Passing by the hospital, passing by Rui Ze…
Yang Baoyi is really scared now. She has no doubt that Meng Fu can make her family disappear quietly!
...
...
etc……
Yang Baoyi suddenly remembered that Butler Yang told her today that Jiang Xinchen had passed away. She wanted to ask Butler Yang about the follow-up, but when she called, it was Butler Yang's son who answered the phone and told her that Butler Yang was sick and in the hospital...
How come you suddenly got sick out of nowhere?
Yang Baoyi huddled together and for the first time felt helpless and desperate.
**
Jiang Xinchen is here.
He followed behind Yu Wu, like a puppet, his brain unable to think normally.
Yu Wu probably knew Jiang Xinchen's current state, so he didn't let him get in the car, but asked him to stand under the car. "Master Jiang, please stand here and calm down first."
After a long time, Jiang Xinchen slowly came to his senses. He looked at Yu Wu, "My sister..."
"Ms. Meng is very powerful," Yu Wu lit a cigarette for himself, biting the cigarette butt and looking at Jiang Xinchen, "Then... the Duan family, right? Don't worry, they won't dare to do anything to us."
Jiang Xinchen nodded.
He really found it hard to believe.
Although he was the young master of the Jiang family, he also knew clearly the gap between the Jiang family and the Yang family, not to mention the Duan family. In particular, in his eyes, Meng Fu was just a star...
"But Master Jiang, you should improve your strength," Yu Wu exhaled a puff of smoke and threw the gun in his hand into Jiang Xinchen's hand, "This is for you."
Jiang Xinchen's fingers were shaking a little, but his eyes gradually became firm.
"Is there anything you want to ask?" Meng Fu arrived late and walked slowly. He put on his hat again and looked at Jiang Xinchen lazily.
Jiang Xinchen clenched the cold gun in his pocket and shook his head, "No."
Meng Fu raised an eyebrow and said, "You go somewhere with someone tomorrow."
Jiang Xinchen didn't ask, just nodded: "Okay."
Meng Fu sat in the back seat, holding up the window with her hand lazily, "Okay, let's go back and eat."
Yu Wu grinned at Jiang Xinchen.
Jiang Xinchen pursed his lips and followed Meng Fu. His mood did not calm down all the way back.
After returning home and finishing her meal, Meng Fu took the draft paper from Jiang Xinchen's room, went back to Jianghe to finish the calculations on the draft paper, then turned on her phone and sent it to Yang Zhaolin.
Meng Fu: [Picture]
Just a very simple step-by-step guide and answers.
On the phone, Yang Zhaolin received Meng Fu's picture.
After dinner in the evening, he didn't find Butler Yang, so he went to the study to continue his calculations. However, he made a note of the incident in his mind, feeling that something was wrong, and planned to go see Butler Yang tomorrow.
When Meng Fu sent him a WeChat message, he quickly clicked it.
They built nuclear submarines. Among modern weapons, nuclear submarines are mostly used for dropping bombs and determining the enemy's position, and the position needs to be used to track and locate enemy information.
The most important thing for a submarine is to use information to locate the target so as to strike with the greatest accuracy. In order to obtain more accurate data, the Karman filter is used to calculate the optimal state.
This can be divided into various situations. Yang Zhaolin and his team use the UHK filtering algorithm.
The UFK algorithm has been proposed a long time ago, but it is still a little way to go before it can be truly applied to nuclear submarines. The research institute's team has already drawn up a simulation scenario, but Yang Zhaolin and his colleagues have conducted various experiments, and these algorithms have not yet been calculated.
The measurement update equation and the time equation can be calculated, but the optimal solution cannot be calculated.
The database is huge, the numbers are large, and there are many interference factors. It will take several days to calculate, but the deadline given to them is tomorrow. If they cannot get the optimal solution, they will have to overturn the algorithm and use the previous algorithm.
Yang Zhaolin thought of Meng Fu that Jiang Xinchen mentioned.
But I just wanted to give it a try, but I didn't expect Meng Fu to actually write down the answer.
UFK Yang Zhaolin had also studied it. The process Meng Fu gave him was very simple, but in the end he got the result and clarified the positioning and tracking accuracy.
Yang Zhaolin looked at the brief steps she sent him and recalculated them.
Meng Fu has strong calculation ability and all the calculation process is in his mind. Yang Zhaolin spent several times more time to calculate.
At four o'clock in the morning, Yang Zhaolin wrote four pages of densely packed information and finally worked out the positioning and accuracy based on Meng Fu's several main formulas.
There was a little dark in his eyes, but he confirmed Meng Fu's calculation.
Yang Zhaolin was overjoyed. Today was the deadline, so he didn't even eat. He took the papers and called Duan Shenmin.
At four o'clock, Duan Shenmin was awakened by a call from Yang Zhaolin, and heard Yang Zhaolin's excited voice: "My cousin has figured it out!"
Duan Shenmin was also calculating last night and didn't go to bed until twelve o'clock. When he heard this, his groggy mind instantly cleared up, "Have you come to a conclusion? Go to the research institute immediately and hold an emergency meeting. I'll call the others."
He quickly got up from the bed, put on his coat, quickly washed up, and contacted other team members to go to the research institute.
**
Yang Baoyi was missing and her phone was unreachable. Pei Xi searched for her all night and finally got through to her and found out that she was in the hospital.
Before she went to the hospital, Duan Shenmin called.
She had to rush to the institute for a meeting.
When I went to the office, several other members of the team had arrived. Duan Shenmin's team had more newcomers. After all, Duan Shenmin himself was a newcomer. Their data team was only the weakest of the five measurement data teams for nuclear submarines.
Pei Xi is considered to be one of the higher ranking ones in Mathematics City.
As soon as she arrived, a middle-aged man asked, "Professor Pei, have you figured it out?"
Pei Xi pressed his forehead, a bunch of data filled his mind, and he shook his head when he heard it, "I don't have it."
The middle-aged man sat back in his chair and sighed.
As the group was talking, Duan Shenmin and Yang Zhaolin came in. Duan Shenmin looked obviously very excited.
Pei Xi was stunned when he saw Duan Shenmin's expression.
Duan Shenmin didn't even notice her. Instead, he rested his hands on the conference table and put the detailed steps Yang Zhaolin had written on the slide. "Our final results are out. Everyone check them. If there are no problems, I'll submit the report right away."
As soon as these words were spoken, everyone in the conference room went wild.
Everyone looked at the screen carefully, and were excited after confirming that the result was really calculated.
"Captain Duan, did you and Zhao Lin figure this out?"
"What kind of brains do you have?"
"Very good!"
“…”
The group of people were talking about it, and Duan Shenmin narrowed his eyes, then raised his hand to tell others not to talk, and finally smiled, "This was calculated by cousin Zhao Lin, Zhao Lin and I will discuss it with her later."
"Zhao Lin, who is your cousin? Your whole family is perverted, right? Pei Xi is the model, and your cousin is the algorithm!"
"Quick, add my cousin to our team, it will be even more powerful..."
“…”
The people in the group were talking among themselves, and no one was looking at Pei Xi.
Pei Xi looked at Yang Zhaolin and frowned: "Which cousin is it?"
Yang Zhaolin breathed a sigh of relief, and smiled when he heard Pei Xi's words, "It's Afu."
"She?" Pei Xi couldn't believe it. She frowned even more. Meng Fu was just a freshman, not even a math major. She was skeptical. "I've written a few model equations and determined the algorithms, but her calculation ability is indeed okay."
Hearing Pei Xi's words, Yang Zhaolin glanced at Pei Xi. He knew that Pei Xi was always aloof, so he didn't say anything.
Duan Shenmin smiled and looked at Pei Xi, "Yes, your cousin is amazing, but when it comes to modeling, who can compare to you, an honorary professor?"
Pei Xi said calmly, "Okay, stop talking about me."
"Okay, I won't say anything more," Duan Shenmin smiled, "I won't compare you with these people. You are the youngest honorary professor and the youngest award winner in the country."
Everyone else laughed.
"But algorithms are sometimes needed. Ask her. It may be difficult to join the team. I will try my best to submit the application," Duan Shenmin said. He glanced at Pei Xi and smiled. "Xixi, I will trouble you to persuade her when the time comes. They are all girls. She may be more likely to listen to you."
Pei Xi curled her lips and looked at the fact that most people in the office showed great interest in Meng Fu. She lowered her eyes and said nothing.
**
Su Huang went to pick up Jiang Xinchen for special training early in the morning.
As for Meng Fu, she had just woken up when she received several WeChat messages from Yang Zhaolin, asking her if she was willing to join the nuclear submarine team.
Meng Fu pressed reply, but replied lazily.
Yang Zhaolin called and said in a serious voice, "Cousin, are you really going to learn how to make perfume? You are..."
For a moment, Yang Zhaolin seemed to be possessed by Dean Li.
He quickly interrupted him, "Brother, if you have any questions later, we can discuss them. Forget about nuclear submarines."
Yang Zhaolin asked her why.
Meng Fu leaned against the sofa and said, "I am a good citizen and I don't deal in weapons."
Yang Zhaolin: “…”
He was silent for a moment, then glanced at Duan Shenmin beside him. Duan Shenmin gave him a look, and Yang Zhaolin felt very complicated. "Then bring Xinchen back for lunch at noon. We want to thank you very much. Also, you helped us solve a big problem, so you deserve a reward."
Meng Fu didn't want to go back to Yang's house for dinner. When she heard about the reward, she paused for a moment, then said quietly, "Since you insist on being so polite, I'll do it with reluctance."
Yang Zhaolin: “……?”
Jiang Xinchen went to train with Su Huang, so Meng Fu naturally couldn't take him back for dinner.
At noon, she asked Su Di to drive her back to Yang's house.
At the Yang family, Duan Shenmin, Pei Xi, Yang Zhaolin were all there, as well as a middle-aged man.
The others didn't see it.
When they are researchers together, the data they discuss are confidential, so they naturally cannot eat in public.
The middle-aged man saw Meng Fu, opened his mouth for a long time, and then stared, "Is this your cousin?"
The person who solved such a difficult algorithm problem turned out to be a famous star? ?
Yang Zhaolin introduced the middle-aged man to Meng Fu. "This is a member of our team, Dr. Wu. He was also my instructor before. He is now in the same engineering school as Xixi. If you follow the news, you should have seen him."
"Hello, Dr. Wu." Meng Fu touched his nose, still quite calm.
She knew nothing about the country except for those people including Dean Li.
It seems that he is not clear about Dr. Wu.
Pei Xi glanced at Meng Fu and then looked away.
Duan Shenmin apologized to Meng Fu and observed her carefully: "Thank you very much this time."
Meng Fu sat down at the table and waved her hands casually, "No need to thank me, I just read about this type of algorithm, found that issue of the journal, and casually drew an analogy with it."
When Pei Xi heard this, he looked up at Meng Fu.
Duan Shenmin and Dr. Wu were also stunned. They thought Meng Fu had calculated it all by herself. "Has there ever been such a journal?"
"Yes, SCI Mathematics 1-S7." Meng Fu said lazily and took the cup handed to her by the servant.
Pei Xi glanced at Meng Fu, then took out his mobile phone and logged into the official website to search.
She flipped to a paper, then sneered and handed it to Duan Shenmin.
Duan Shenmin took it and took a look. 1-S7 was a journal from four years ago. This type of journal is outdated. There was indeed an article on the calculation of UFK. It was a bit brief, but it was indeed somewhat similar to today's one.
He was stunned for a moment, then looked at Meng Fu, "You know all these old journals, and you can understand them, which means you are not bad."
It's just a little bit different from what I calculated myself.
Yang Zhaolin didn't believe that Meng Fu was taking advantage of the situation, but how did Meng Fu know about SCI journals? Didn't she basically not read them?
He looked at Meng Fu suspiciously.
Dr. Wu also looked at Meng Fu and continued, "You have so much knowledge..."
Meng Fu: "...No, I just watched that episode."
Meng Fu is a star. Dr. Wu heard from Yang Zhaolin that she was the top scorer in the college entrance examination. She used analogy to solve the algorithm. Dr. Wu was very curious about her and kept asking her questions throughout the dinner. Duan Shenmin also paid close attention to her: "I heard that your college entrance examination math is very difficult?"
Meng Fu nodded: "A little bit."
Zhou Da intervened and even Jin Zhiyuan suffered a setback.
Dr. Wu admired, "Then you can get full marks."
"Does the professor know about the SCI paper on the difficult math problem last time?" Yang Zhaolin looked at Professor Wu with a smile, "Afu can understand it too."
Professor Wu's eyes lit up, and he looked at Meng Fu, "You just finished the college entrance examination, can you tell me your opinion?"
Meng Fu glanced at Yang Zhaolin, then leaned back in her chair and squinted her eyes. "I think the most important thing about that paper is the final theory of mind space, the Poincare conjecture..."
Pei Xi also read this paper.
What Meng Fu said was just the ending of the paper.
She sneered.
Pei Xi could hear it, and Dr. Wu naturally heard it a little bit as well. However, Duan Shenmin didn't know much about the paper, so he didn't hear it very well.
While still asking Meng Fu other questions.
Pei Xi was annoyed and didn't want to listen to Meng Fu anymore. He quickly finished his meal and got up to go upstairs to find Yang Zhaolin's computer. "I'll use my cousin's computer to calculate the model. I just need to finish it."
Yang Zhaolin’s computer is better than the one in the laboratory. They all know that they came here today to do calculations and modeling.
When they heard her calculating the model, Duan Shenmin and Dr. Wu put down their chopsticks and followed her before they finished eating, "Wait, I'll go take a look too!"
They quickly said hello to Meng Fu and went upstairs.
Didn't look back either.
Yang Zhaolin didn't go upstairs, but just looked at Meng Fu, not quite believing it: "Is that really your analogy?"
Meng Fu: "..."
Holmes Young?
She paused, then changed the subject, "Where are my uncle and aunt?"
"They went to the hospital to see my aunt. Her hand was broken." When Yang Zhaolin thought of this, his thoughts were diverted and he frowned.
Yang Baoyi's injury was somewhat unpredictable.
Meng Fu lowered her eyelashes, hiding the coldness in her eyes. She picked up a vegetable and said, "If you want to see her, take me with you."
Yang Zhaolin nodded and asked about Jiang Xinchen again, "I'll take you back later and send his airplane model back, and let's go see my aunt together."
"This is the model they are studying," the two of them finished their meal leisurely. Yang Zhaolin did not go upstairs to discuss with Pei Xi. He always felt that something was wrong with Meng Fu. He showed Meng Fu his research next to him and said, "What do you think of this calculation model?"
Meng Fu took a look and roughly understood the model. "This model needs to be recalculated. The budget state covariance looks..."
"How does the transfer term look?" Pei Xi just came down from upstairs. She had been holding back for a whole day, but finally couldn't hold back any longer and directly took the document from Yang Zhaolin's hand. "Meng Fu, this took us a week to calculate, and I have just confirmed the result. Don't say 'you look' anymore. I admit that your algorithm is good, but the most important thing about mathematics is the relationship between models and space. Algorithms can be replaced by computers. Since you are so interested in mathematics, go back and take a good look at the origin of mathematics, study it for two or three years, and then you can comment on these papers and models. Do you know what book the origin of mathematics is?"
