Security Agency.

The second she saw the "Security Bureau", Yang Baoyi almost fainted!

How could it be here?!

Doesn't the Security Service ignore ordinary cases?

Who the hell is Meng Fu?!

She has done a lot of dirty things in her life, and she doesn't know how many times she has done threatening things, even more so than Jiang Xinchen.

When she threatened Jiang Xinchen, she only called two people casually, because she really didn't take Jiang Xinchen seriously.

This is the first time she has been threatened, and it is still a threat to the lives of her entire family.

Passing through the hospital, passing through Ruize......

Now Yang Baoyi is really afraid, she has no doubt that Meng Fu can make her family disappear quietly!

Wait a minute......

Yang Baoyi suddenly remembered that Steward Yang told her that Jiang Xinchen was gone today, and she wanted to ask Steward Yang about the follow-up, but when she called, it was Steward Yang's son who picked her up and told her that Steward Yang was sick and in the hospital......

Why did you suddenly get sick all of a sudden?

Yang Baoyi huddled together, feeling helpless despair for the first time.

**

Jiang Xinchen's side.

He followed behind Yu Wu, his whole person was like a marionette, and his brain was no longer able to think normally.

Yu Wu probably also knew Jiang Xinchen's current state, and didn't let him get into the car, letting him stand under the car, "Young Master Jiang, you stand and calm down first." ”

After a long time, Jiang Xinchen's mind slowly turned, and he looked at Yu Wu, "I, my sister, she ......"

"Miss Meng is very powerful," Yu Wu pinched a cigarette and lit it for himself, biting the cigarette butt and looking at Jiang Xinchen, "What's that...... The Duan family, right? Don't worry, don't dare to do anything to us. ”

Jiang Xinchen nodded.

He was a little hard to believe.

Although he is the young master of the Jiang family, he also clearly knows that the gap between the Jiang family and the Yang family, not to mention the Duan family, especially Meng Fu in his eyes, is just a star......

"But Young Master Jiang, you should improve your strength," Yu Wu let out a puff of smoke and threw the gun in his hand into Jiang Xinchen's hand, "This is for you." ”

Jiang Xinchen's fingers trembled a little, but his eyes gradually became firm.

"Is there anything you'd like to ask?" Meng Fu was late, walking slowly, buttoned 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 his eyebrows, "Tomorrow you go somewhere with someone." ”

Jiang Xinchen didn't ask, and nodded directly: "Okay." ”

Meng Fu sat in the back seat, leaning on the window with his hands lazily, "Okay, go back to dinner." ”

Yu Wu grinned at Jiang Xinchen.

Jiang Xinchen pursed his lips and followed behind Meng Fu, and his mood did not calm down on the way back.

After going back to eat, Meng Fu took the draft paper from Jiang Xinchen's room, went back to Jianghe to finish the draft paper calculation, and then turned on his mobile phone and sent it to Yang Zhaolin.

Meng Fu: [Picture]

Just a very brief step and answer.

On the other side of the phone, Yang Zhaolin received a picture of Meng Fu.

After he finished eating at night, he didn't find Steward Yang, so he went to the study to continue the calculation, but he wrote down this matter in his heart, and always felt that something was wrong, and he was going to see Steward Yang tomorrow.

When Meng Fu sent him WeChat, he hurriedly clicked on it.

They are building nuclear submarines, which are used to drop bombs and determine the enemy's position more often in modern weapons, and need to use the bearing to track and locate enemy information.

The most important thing for submarines is to use information to locate the place in order to strike the most accurately, and in order to get more accurate data, it is necessary to use Karman filtering to calculate the optimal state.

This has to be divided into various situations, Yang Zhaolin and they use the UHK filtering algorithm.

The UFK algorithm has long been proposed, but if it wants to be really applied to nuclear submarines, it is still a little close, and the team of the research institute has drawn up simulation scenarios, but Yang Zhaolin and they have done various experiments, and these algorithms have not 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 various interferences, so it takes several days to measure, but the time given to them above is until tomorrow, and if they can't get an optimal solution, they will have to overturn the algorithm again and use the previous algorithm.

Yang Zhaolin thought of what Jiang Xinchen said about Meng Fu.

But with the idea of trying it out, I didn't expect Meng Fu to really write the answer.

UFK Yang Zhaolin also studied that the process given to him by Meng Fu was very brief, but in the end, he got the results and clarified the positioning and tracking accuracy.

Yang Zhaolin looked at the brief steps she sent and recalculated.

Meng Fu has strong calculation ability, and the calculation process is all in his head, and Yang Zhaolin spent several times more time to calculate.

At four o'clock in the morning, Yang Zhaolin wrote four sheets of paper, and finally wrote out the positioning and accuracy according to several main formulas of Meng Fu.

His eyes were a little blue and black, but it confirmed Meng Fu's algorithm.

Yang Zhaolin was overjoyed, today was the deadline, he didn't even eat, so he called Duan Shenmin with these papers.

At four o'clock, Duan Shenmin was woken up by Yang Zhaolin's phone, and heard Yang Zhaolin's excited voice: "My cousin has calculated it!" ”

Duan Shenmin was also calculating last night, and he didn't go to bed until twelve o'clock, and when he heard this, his groggy brain instantly woke up, "Conclusion?" Immediately go to the research institute, have an urgent meeting, and I call the others. ”

He quickly got up from the bed, put on his coat, and while washing up quickly, he contacted the rest of the team to go to the research institute.

**

Yang Baoyi was missing, the phone couldn't get through, Pei Xi looked for a night, and finally called her and knew that she was in the hospital.

Before she could go to the hospital, Duan Shenmin's phone called.

She had to hurry to the research institute for a meeting.

When I went to the office, there were several other people in the group, and there were more newcomers to Duan Shenmin's group, after all, Duan Shenmin was a newcomer himself, and their data team was only the weakest of the five nuclear submarine measurement data groups.

Pei Xi is one of the higher ones in Math City.

Since her, a middle-aged man has asked, "Professor Pei, have you figured it out over there?" ”

Pei Xi pressed the door of his head, a bunch of data filled his mind, and when he heard the words, he shook his head, "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 outside, and Duan Shenmin's expression was obviously very excited.

Pei Xi looked at Duan Shenmin's expression, and the whole person was stunned.

Duan Shenmin didn't notice her at all, but propped his hands on the conference table and put the steps written in detail by Yang Zhaolin on the slide, "Our final results have come out, everyone checks them, if there are no problems, I will submit the report immediately." ”

As soon as this sentence was written, the entire conference room was fried.

Everyone looked at the screen carefully and was excited when they made sure it was really calculated.

"Team Duan, did you calculate it with Zhao Lin?"

"What kind of brains are you?"

"Great!"

“……”

The group talked a lot, Duan Shenmin squinted, then raised his hand to ask the others not to speak, and finally smiled, "This is calculated by Cousin Zhaolin, I will talk to her with Zhaolin and the others." ”

"Zhaolin, who is your cousin? You're all perverts, aren't you? The model has Pei Xi, and the algorithm has a cousin! ”

"Quick, add my cousin to our team, like a tiger with wings......"

“……”

There was a lot of discussion in this group, and no one looked at Pei Xi anymore.

Pei Xi looked at Yang Zhaolin and wrinkled his eyebrows: "Which cousin is it?" ”

Yang Zhaolin breathed a sigh of relief, and when he heard Pei Xi's words, he smiled, "It's Ah Fu." ”、

"She?" Pei Xi couldn't believe it, her brows tightened, Meng Fu was just a freshman, not a math major, her tone was skeptical, "I have written a few model equations and determined the algorithm, but her calculation ability is really okay." ”

Hearing Pei Xi's words, Yang Zhaolin glanced at Pei Xi, he knew that Pei Xi had always been arrogant, so he didn't speak.

Duan Shenmin looked at Pei Xi with a smile, "Yes, your cousin is powerful, but who is comparable to you as an honorary professor in terms of modeling." ”

Pei Xi said lightly, "Okay, don't talk to me." ”

"Okay, I won't say it," Duan Shenmin smiled, "Don't compare these people with you, you are the youngest honorary professor and the youngest recipient in China." ”

Everyone else laughed.

"But the algorithm does need it sometimes, just ask her, it may be a little difficult to join the group, I will try my best to submit the application," Duan Shenmin said, looked at Pei Xi again, and smiled, "Xixi, I will trouble you to lobby at that time, they are all girls, she may be more obedient to you." ”

Pei Xi pulled her mouth, seeing that most people in the office showed great interest in Meng Fu, she lowered her eyes and did not speak.

**

Su Huang went to pick up Jiang Xinchen early in the morning for special training.

Meng Fu here, as soon as she got up, she received a few WeChat messages from Yang Zhaolin, asking her if she would like to go to the nuclear submarine team.

Meng Fu replied, lazily unable to go back.

Yang Zhaolin's phone called, and his voice was serious: "Cousin, are you really going to learn any perfume?" That's how you ......"

For a moment, Yang Zhaolin seemed to be possessed by Dean Li.

Hurriedly interrupted him, "Brother, if you have any problems in the future, we can discuss it, and forget about the nuclear submarine." ”

Yang Zhaolin asked her why.

Meng Fu leaned on the sofa, "I am a good citizen, and I don't engage in weapons." ”

Yang Zhaolin: "......"

He was silent for a moment, and glanced at Duan Shenmin beside him, Duan Shenmin gave him a look, Yang Zhaolin was in a very complicated mood, "Then bring Xinchen back for dinner at noon, we have to thank you well, and besides, you helped us solve a big problem, and we should pay you." ”

Meng Fu didn't want to go back to Yang's house for dinner, but when she heard the reward, she paused for a moment, and then said quietly: "Since you have to be so polite, then I will make it difficult for you." ”

Yang Zhaolin: "......? ”

Jiang Xinchen went to train with Su Huang, and Meng Fu naturally couldn't take him back to eat.

At noon, she asked Su Di to drive her back to Yang's house.

The Yang family, Duan Shenmin, Pei Xi, Yang Zhaolin are all there, and there is a middle-aged man.

The others didn't see it.

When they are scientific researchers, the data they discuss are all confidential data, so naturally they can't eat in public at will.

When the middle-aged man saw Meng Fu, he opened his mouth for a long time before glaring, "This is your cousin?" ”

Solving such a difficult algorithm problem turned out to be a star who is popular all over the sky??

Yang Zhaolin introduced the middle-aged man to Meng Fu, "This is from our team, Dr. Wu, who was also my instructor before, and now he is in the same engineering academy with Xixi, if you follow the news, you should have seen him." ”

"Hello, Dr. Wu." Meng Fu touched his nose, quite calm.

She didn't know anything about it in China except for Dean Li's people.

It doesn't seem to be clear to Dr. Wu.

Pei Xi glanced at Meng Fu and withdrew his gaze.

Duan Shenmin apologized to Meng Fu and observed her carefully: "Thank you this time." ”

Meng Fu sat down at the dinner table and waved his hand casually, "Don't thank me, I just looked at this kind of algorithm, found the journal of that issue, and brought it in by random analogy." ”

When Pei Xi heard this, he looked up at Meng Fu.

Duan Shenmin and Dr. Wu were also stunned, they thought it was completely Meng Fu's own calculations, "Have you ever had this journal?" ”

"Well, SCI Mathematics 1-S7." Meng Fu opened her mouth 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 in to the official website to search for it.

She flipped to a paper, then sneered and handed it to Duan Shenmin.

Duan Shenmin took it and took a look, 1-S7 is still a journal from four years ago, this kind of journal is outdated, there is indeed a calculation about UFK, which is a little sketchy, but it is indeed somewhat similar to today's one.

He was stunned for a moment, then looked at Meng Fu, "You know such a long time ago, and you can understand it, which means that you are not bad." ”

It's a little worse than what you calculated.

Yang Zhaolin didn't believe that it was Meng Fu's own opportunism, 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 the waves were endless: "Your knowledge is too extensive......

Meng Fu: "...... I didn't have any, so I watched that issue. ”

Meng Fu is a star, Dr. Wu heard Yang Zhaolin say that she was the top student in the college entrance examination, and she solved the algorithm by analogy, Dr. Wu was very curious about her, and asked her throughout the dinner, Duan Shenmin was also very concerned about her: "You have heard that the college entrance examination mathematics is difficult?" ”

Meng Fu nodded: "A little." ”

Zhou Da interfered, and even Jin Zhiyuan was Waterloo.

Dr. Wu admired, "Then you can get a full score." ”

"Does the professor know about the SCI paper on the math problem last time?" Yang Zhaolin looked at Professor Wu with a smile, "Ah Fu can also understand it." ”

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 his chair and squinted slightly, "That paper, I think, the most important thing is the final theory of mental space, where Poincaré guesses ......"

Pei Xi also read this paper.

All Meng Fu said was the end of the paper.

She scoffed.

Pei Xi could hear it, and Dr. Wu naturally heard it a little, but Duan Shenmin didn't know much about that paper, so he didn't hear it much.

Still asking Meng Fu for other times.

Pei Xi was annoyed by hearing this, and didn't want to listen to Meng Fu say this anymore, so he got up after eating quickly, and went upstairs to find Yang Zhaolin's computer, "I'll use my cousin's computer to calculate the modeling, and I'm almost the last point." ”

Yang Zhaolin's computer is better than the laboratory, and they all know that they came here today to calculate and model.

Hearing that she was calculating, Duan Shenmin and Dr. Wu both put down their chopsticks and followed before they finished eating, "Wait, I'll take a look too!" ”

They hurriedly said hello to Meng Fu and went upstairs.

Didn't look back.

Yang Zhaolin didn't go upstairs, only looked at Meng Fu, not quite convinced: "Is that really your analogy?" ”

Meng Fu: "......"

Formo Young?

She paused for a moment, then changed the subject, "What about my uncle and aunt?" ”

"They went to the hospital to see my aunt, who had a broken hand." When Yang Zhaolin thought of this, he was also diverted from his train of thought, and he frowned.

Yang Baoyi's injury is a little unpredictable.

Meng Fu lowered her eyelashes, covering the coldness at the bottom of her eyes, and she sandwiched a vegetable with her: "If you want to go see her, take me with you." ”

Yang Zhaolin bowed his head and asked about Jiang Xinchen again, "I'll send you back later, and send his model plane back, and let's go see my aunt together." ”

"That's what they're studying," the two finished eating slowly, and Yang Zhaolin didn't go upstairs to discuss with Pei Xi, he always felt that there was something wrong with Meng Fu, and showed Meng Fu his research next to him, "What do you think of this calculation model?" ”

Meng Fu glanced at it and roughly understood the model, "This model needs to be re-measured, the covariance of the budget state looks ......"

"What does the transfer item look like?" Upstairs, Pei Xi just came down, she endured it for a day, and finally didn't hold back, and directly took away the documents in Yang Zhaolin's hand, "Meng Fu, this is what we calculated in a week, I have just determined the result, you don't want to 'you look' or anything." I admit that your algorithm is good, but the most important thing in mathematics is the model and space, and the algorithm can be replaced by a computer, 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 will comment on these papers and models, do you know what kind of book the origin of mathematics is? ”

It took a long time to study UFK.

Fourth, try to write a little longer to compensate everyone~
