Hammer of Technology

Hearing this, Xiao Pan was a little dazed, then raised his head and asked, "Senior Brother Zhang, have you ever attended a lecture in a mathematics institute before? Haven't you ever been hit? Otherwise, how do you know so clearly?"

Hearing this, Zhang Yancheng was stunned for a moment, and unconsciously recalled in his mind that when he went to the math school to listen to two random process classes, and then shut himself up for about a month, he subconsciously took a picture. Xiao Pan's head: "You are the only one who has a lot to do!"

……

Ning Wei didn't have time to realize how complicated the mood of those members of the project team was at this moment.

After hanging up the phone with Academician Tan Tan, he was planning to discuss with Jiang Chenshuang when he would complete the promise to invite everyone to a meal, when there was a knock on the office door, and Tian Yanzhen opened the door and walked into his office as soon as he spoke.

Seeing Jiang Chenshuang who was tidying up his desk, the math guru was obviously stunned for a moment, and then said, "Student Jiang is here too, didn't I bother you?"

"No, I'm just here to deliver a meal to Ning Wei, so I'm leaving now." Jiang Chenshuang replied hastily.

"No hurry, no hurry, I just stopped by to ask Ning Wei something, Ning Wei, I just heard that Lao Tan just called and said that you have helped them solve the problem?" Tian Yanzhen asked.

"Well, yes. They called in the afternoon and said that the problem has been solved." Ning Wei replied.

"Oh, that's a good relationship. It just so happens that Chenshuang is here, so don't lock yourself in the office and take people out for a stroll. By the way, let me tell you, your brother Lu recently opened a new project, which may be more Busy, don’t you have more free time here, why don’t you go and help Brother Lu as his teaching assistant, and occasionally help him substitute for his class, correct homework and test papers, are you okay?” Tian Yanzhen said.

"Huh? Teaching assistant?!"

"Well, that's it! It's too much work! By the way, Lao Tan said he wanted to talk to you, but I refused for you, saying that if you are not here today, I should be able to get you a teaching assistant certificate this week. , turn around and Lao Tan will talk to you again, you can just slap your teaching assistant certificate on his face, understand?" Tian Yanzhen said seriously.

183 Optimal solutions in nonempty bounded convex sets

Take a teaching assistant certificate and fall on the face of an academician?

It is natural for Tian Yanzhen to say this, but Ning Weiran cannot take it seriously.As for the position of teaching assistant, to be honest, Ning Wei is not too resistant.Anyway, it's not that Gang has never taught classes. During the summer vacation, he has taught many postgraduate students twelve classes, at least he won't be frightened.

If it's just helping Senior Brother Lu to substitute for the class, it's actually fine.After all, Lu Dongyi also helped him a lot during his growth. He occasionally helped with two classes, and it was not a big problem to correct homework and papers.

Anyway, there are not many homework that need to be corrected in college.At least Ning Wei didn't think that Lu Dongyi would spend too much time on correcting homework.

As for taking Jiang Chenshuang out for a walk...

"Let's go back and watch Sanyue, it happens to come alive." Ning Wei suggested as soon as Lao Tian left.

"I have class tonight."

"Your schedule is so tight? Do you still have classes at night?"

"The professor of Introduction to Economic Law went to a meeting last week, so the courses he missed last week were arranged to make up for tonight and Friday night."

"Then I'll take you back to the dormitory first, and then I'll go back to find March."

"Oh!"

……

What made Ning Wei quite satisfied was that Jiang Chenshuang was probably used to being held by him as soon as he walked out the door. The professor came across.

Both of them froze when their eyes met.

"Hello, Academician Tan, are you here to see Mr. Tian? He just went out." Ning Wei said immediately.

Classmate Jiang struggled quietly, but unfortunately he couldn't break free, so he stood obediently beside Ning Wei, with his head bowed slightly.Although she was used to being held by Ning Wei's hand in school, she still panicked in front of the professor.

"Ahem, actually I'm hungry and I didn't come to find your director Tian, ​​this should be your little girlfriend?" Probably because Jiang Chenshuang was beside him, the old professor who was already quite imposing also slowed down his tone.

"Yes, her name is Jiang Chenshuang, from our school's School of Economics. Chenshuang, this is Academician Tan Dejie, the deputy dean of our school's School of New Materials." Ning Wei introduced to both parties.

"Hello, Academician Tan." Jiang Chenshuang greeted Tan Dejie.

"Oh, Xiao Jiang, hello, are you in your junior year? Have you decided to apply for a postgraduate student with a tutor? I have a good relationship with many professors in your college. I'll help you say hello after I've chosen one." Tan Dejie said kindly. .

"Thank you, Academician Tan, but I don't plan to take the postgraduate entrance examination. I will find a job first after graduation." Jiang Chenshuang replied softly.

"Ah, huh?" Tan Dejie glanced at Ning Wei, and found that Ning Wei had nothing to say, which made him a little puzzled. Ning Wei's girlfriend didn't choose to go to graduate school?This answer really interrupted his train of thought.

"Well, that's it. I'll send Chenshuang back first. See you, Academician Tan." After speaking, Ning Wei pulled Jiang Chenshuang around Old Tan and walked away.

The young man is going to fall in love, but he forcibly blocks her at this time, which is a loss of favor.

……

"You really don't plan to go to graduate school." Ning Wei asked.

"Yeah, I want to work early." Jiang Chenshuang nodded.

Ning Wei thought about it, and didn't continue this topic. It's still early in junior year, so there's no need to forcefully change the girl's mind now.

"By the way, Director Tian has a conflict with Academician Tan? Why did Director Tian ask you to smash your teaching assistant certificate on Academician Tan's face?" the girl asked.

"Academician Tan probably thinks I'm more talented and wants me to study for a double doctorate in material science." Ning Wei said truthfully.

Jiang Chenshuang looked at Ning Wei in surprise, and said, "Are you Xiangmomo?"

Ning Wei glanced at the girl next to him in even more surprise, and said, "My God, you just found out? You know that when I go to the stoc conference, I just nod and I can choose any college from the Ivy League? By the way, it's not an invitation." I went to study abroad to be a professor. A professor at Harvard also said that if I want a doctoral certificate from Zhang, he will print it for me, and I can choose from any school I want.”

The girl blinked, looked up at Ning Wei, and asked, "Then why didn't you agree?"

Ning Wei replied as a matter of course: "Of course because of you."

The girl was stunned, unable to recover for a while, and pointed to herself: "Because of me?"

Ning Wei nodded, and replied: "Didn't you agree that I would go to a meeting to win glory for the country, and you would agree to be my girlfriend when I came back? Do you want to study abroad?"

Jiang Chenshuang subconsciously shook her head.

Ning Wei immediately said: "That's it. I guess you never thought about studying abroad. After all, it's too far away to take care of your sister and family, so you simply refused. The professor also said, I want to turn my thesis into a teaching material. It seems to be said in the news that Google invested 100 million US dollars to make that teaching material, including the cost of editing the thesis and arranging courses in the university in the future. At that time, I just wanted to ask me to teach this in person. course."

The argument is very strong. After deciding to sponsor, Google specifically mentioned it at the press conference, and the news has already spread to China, and it can indeed be found.

The girl was a little bored, and asked after a long while: "Ning Wei, can you tell me what is good about me? Don't you really think that there is actually a big gap between us?"

Hearing this question, the words of Xu Ruixuan roaring at Xu Mo shamelessly at the school gate appeared in Ning Wei's mind for no reason.

"You, you, why didn't you show up earlier? I didn't meet you until I was in my senior year? It made me feel like I wasted the best time of my four years in college! Silently, why did you hide from me for so long? Why can't you Let me see you on bbs soon..."

Then I got goosebumps all over my body, well, this completely shameless approach is not suitable for him after all.

"this problem……"

Ning Wei frowned and thought carefully. He had an intuition that this seemingly inconspicuous question was actually very important: "Actually, I have been trying to interpret love from the most rational perspective. I have also read some books on biology to understand I understand the influence of hormones in the body on human emotional characteristics, such as phenylethylamine, dopamine and endorphins, how to affect different senses in different stages of love through neurotransmitters. But then I gave up, do you know why? "

Jiang Chenshuang shook her head blankly. Although she has never been in a relationship, she still feels that the style of painting is a bit wrong, so she needs to study biology before falling in love?Is a scumbag really not worthy of a relationship?

"Because it is difficult to explain love from a purely rational point of view. It can only be attributed to the pure physical manifestation of the brain subconsciously activated by hormones. More specifically, it is the irritability and anxiety that are manifested because they cannot get enough hormones when they cannot meet each other. Symptoms. These are the most direct physical reactions."

"Then analyze your question rationally. In fact, the question is not what I like about you, but whether simple liking can be transformed into a more lasting and stable relationship between the sexes, such as marriage. I have also thought about this question carefully. , After all, the phenylethylamine produced at first sight and the dopamine produced at the time of heat cannot be sustained, and endocaffein is ultimately needed to stabilize people's emotions."

"Now it is confirmed that I like you, and I can even rise to the height of love, because during the few days when you lost contact, I can clearly feel my emotional instability, which is specifically manifested as anxiety, and no one is pleasing to the eye. Now that the conditions have been met, we know that the essence of love is a linear program, and the variables we need to bring in here are time and goals.”

"In the linear programming problem, the Hessian matrices of the objective function and the constraint function are both positive definite, and because the Hessian matrices of the linear function are all zero matrices, they are all positive semi-definite, so the linear programming is a convex programming, so As long as the feasible domain is bounded, there must be an optimal solution. And the optimal solution of the linear programming problem must exist when the feasible domain is non-empty and bounded, and appear on the vertices or boundaries of the region."

"Then what is my goal? That is, what is the constraint function? It is actually very simple. I hope to do as much research as possible in my limited life, so I am destined not to spend too much energy and time on love. So after I fell in love with you, I have no more time and energy to like another opposite sex. Therefore, from the introduction of all the above conditions, we can see that you and I are the best in the non-empty bounded convex set Excellent solution, there is no one."

"So the essence of this problem is not where I like you, but that many things have been doomed after the condition of liking happened. Then what should you do if you refuse? We continue to bring in and we will find that when the feasible domain is empty, There is obviously no optimal solution for the linear programming problem. So the result is that we are separated, and there is no optimal solution. For me, the future may be to devote myself to research and live with March. For you The trajectory of life may not be very different. So the question is, mathematically speaking, when there is an optimal solution, would you choose to go another way?"

Really, Jiang Chenshuang was completely stunned.

After asking the question just now, she thought of various possible answers in her mind, but she didn't expect to get an answer that she seemed to understand, but she didn't seem to understand, so she felt confused.

At this time, the girl's appearance fell into Ning Wei's eyes, like a very ripe apple, especially the red lips, so Ning Wei followed his heart and bowed down without hesitation while classmate Jiang was wandering in the sky. Head down, pecked...

It's soft and a little cold, but it feels really good. No wonder that guy Xu Ruixuan thinks of crooked thoughts all day long.

"Ah..." This also awakened Jiang from his stupor, subconsciously took a step back, and looked at Ning Wei with a blushing face.

"Well, that, is there any more questions? Ms. Best Solution?"

Jiang Chenshuang subconsciously shook her head, feeling a little flustered, is this the feeling of a first kiss?Seems pretty good too...

"Ahem, it's fine if you don't have one! Remember, you don't have to believe me, but you have to believe in science. After careful scientific analysis just now, it has been deduced from a mathematical point of view that the love between us is the best solution for each other. Regarding this Do you have any questions? Do you need me to list the formula for you?" Ning Wei asked seriously.

Jiang Chenshuang shook his head.

"Well, that's fine, let's go!"

……

Ning Wei was very satisfied with his explanation. It was obvious that his love theory on the optimal solution of mathematics was recognized. For example, today, Jiang Chenshuang was sent to the door of the dormitory building, and the girl said goodbye to him timidly before entering the building.

This made him feel very comfortable all the way back home, until he walked into the room and looked at the lazy cat on the lit screen, which was still struggling with the problem from last night.

Yes, the alternative test he gave to March last night is still optimizing the laboratory procedures and building mathematical models until now.However, to Ning Wei's delight, in the process of repeated calculations, the solution given was indeed approaching the results in the paper, which meant that Sanyue did not simply rely on the exhaustive method to solve the problem.

After checking the calculation process in the background, Ning Wei found that Sanyue was indeed constantly summing up experience and constantly eliminating ineffective or counterproductive solutions.At least as far as the laboratory assistant is concerned, March is undoubtedly very qualified. At least using it to integrate the plan can save a lot of time in the early stage.

After roughly browsing it, Ning Wei ignored this, as long as he continued in this mode, as long as he gave March enough time, he believed that March would definitely be able to calculate the correct result, since he decided to give March Upgrade the hardware, and let this lazy cat do these computing power-consuming calculations after the upgrade.

So, he directly gave the email address and password specially for March to apply for, and then helped March to accept all three paper review tasks lying in the mailbox in one go.

"March, starting today you are not only a laboratory assistant, but also a competent paper reviewer. Conduct preliminary review of these mathematics papers, find out the mistakes in them, and propose revision suggestions, understand? I will give you a set A small task, if you can successfully review twenty mathematics papers, I will upgrade your little home for you, how about it?"

Ning Wei said in a persuasive manner.

"Meow..." Sanyue, who had been lazily lying there all this time, suddenly became energetic, and finally supported her body with her limbs. She tilted her head and looked at Ningwei, then raised a small paw, pulled it, and directly opened the WeChat dialog box. pulled over its head.

"The guy who lied to the kitten wets the bed at night and gets beaten by his mother!"

Look, look, my daughter has grown up and knows that when good things happen, she needs to be sure twice...

It's just that the threat doesn't seem to be too lethal.

"Hehe, March, isn't my reputation high enough? Have I lied to you before? You should think about how to do a good job of reviewing manuscripts. I will show you how to review the first manuscript. No matter, come, come, let's see what the title of the first manuscript is, um, the generalized operation matrix of mixed partial derivative terms and its application to multi-order fractional partial differential equations. The title is very important, it probably I can tell you the research direction of this paper, the second step, we need to look at the abstract..."

------------

184 You Can!

What kind of experience is it like to review manuscripts for artificial intelligence professors?

There is no doubt that Ning Wei has the most right to speak on this issue now, because being a teacher in March is a very comfortable thing.For the ability to understand mathematical formulas, Sanyue clearly surpassed the category of genius.

Whether it's separation of variables, homogeneity, or Bernoulli's equation, or various abstract concepts of space, it doesn't seem to be a problem for March to understand.In particular, Sanyue's understanding of various abstract spaces surprised Ning.

When it comes to paper review, it is easy to understand the author's thinking, especially the proof process of various lemmas and theorems, and the verification calculation can be completed quickly.

If you fail to pass the verification operation, or have doubts about the proof process, you will mark it yourself.The only thing that gave Ning Wei a headache was that after giving the mark, Sanyue always had a strong mocking style in her wording.

"The proof of Lemma 3.6 gives me the feeling that you think the essence of mathematics is to three-dimensionalize a bunch of messy concepts!".

"A great mathematician once left a sentence in his mathematics notes after a conjecture, 'I have thought of a wonderful proof scheme, but because the space left on the page is too narrow, I can't write it', Later, this conjecture embarrassed the entire mathematics community for hundreds of years. The condensed proof process has 130 pages, so please tell me, is your proof of Theorem 3 omitted because the computer storage space is insufficient? Bifermat?"

"I decided to complete the proof process of this lemma for you by myself, to prove that I understand your idea that you have completely gone astray."

"I suggest you to study physics, because I have to go to the laboratory at least for physics papers, instead of just using a few simple calculations and reasoning, I can point out how absurd the theorems in your paper are by contradiction!"

Not even the editor of one of the papers was spared.

"I heard that all papers need to go through preliminary review, so please tell me, as the paper editor, you have received the benefit of a big house from the paper author, and it is not good to reject him, her or it directly, so you decided to publish this paper Is sending it to reviewers a waste of reviewers’ time? My suggestion is to reject the manuscript immediately, and then close the author’s account immediately to prevent him from submitting manuscripts in the future!"

Of course, the style of replying to the other two papers is not particularly friendly.

"This paper is slightly better than the one I reviewed just now, so I won't ask the author to change his career to study physics. But please explain the questions I raised carefully, otherwise I will suggest rejection."

"Although this paper neither raises any important issues nor solves any important issues, at least he has some new insights and cites the latest Ningwei space theory, and the demonstration process is quite rigorous. It is recommended that he complete the theorem Published after the proof process."

……

Ning Wei fell into deep thought when he saw these replies given by March, and he began to reflect on whether it was correct for him to pretend to be himself and practice his understanding of semantic context with the three sluts in the dormitory every day.The story of Meng's mother's three relocations has already told everyone the importance of the environment to individual growth, but he just ignored how correct the saying is.

The kitten on the screen is still tilting its head and looking at Ningwei outside the screen. It is probably used to this posture. Its eyes are wide open, and it is looking forward to the sitting Ningwei through the screen. , Ning Wei suddenly felt that even a little harsh tongue was not unacceptable.

After all, Sanyue is so cute, even if her mouth is a bit poisonous, it is forgivable.And doing mathematics research, if you don't have a strong heart, you will not be able to go far on the road of mathematics.

So Ning Wei finally nodded and said, "I think it's almost done. The efficiency in March is really high. Now let's see if anyone continues to send you papers for you to review. Remember the number and make up enough." Remember to notify me, and I will start to help you find a new home."

"Meow……"

With a meow, the dialogue pop-up window popped up again.

"Go and find another seventeen articles!"

After seeing this request, Ning Wei was taken aback, so is March's innate need for more computing power and larger storage space?

"Aren't your current resources enough?"

The little milk cat stood up, paced, and began to jump out of the dialog box one by one: "Without having to put in more effort, who would dislike having more resources under their control?"

Ning Wei felt that this sentence made sense, but he couldn't find anything to refute.
