Chapter 237 [He Is Not God] (for Subscription)

Yenching, Huaqing University.

Although Lin Shu went to the party with Yang Yu and Liu Zheng at night, it is obvious that he will not follow Yang Yu all the time. What he can do is to avoid such a tragedy in the real world at 18:20 , As for the other things he can do, there is really not much he can do, and those few chicken soup words are already his best.

Lin Shu was naturally busy with his own affairs.

Because Cheng Xu has already returned to school, the team that Liu Zheng invited Lin Shu to form a successful team is really complete, and the next step is the team battle of the postgraduate mathematical modeling competition.

Liu Zheng has made an agreement with Cheng Xu to practice the competition in the computer room in the afternoon.

Soon there will be a national team battle. Before the team battle, we will naturally have to practice a lot. No matter whether we can win this national battle or not, we still have to prepare carefully. After all, the victory is not decided. Who will be the champion in the end? , no one can tell.

【Ding! Congratulations to the player for running 3 kilometers in the morning and getting 1. experience value +568; 2. gold coins +56. 】

As always, Lin Shu got up early and went for a morning run to gain experience, and then took the opportunity to gain a sense of presence in front of the academician Zhao Shiyuan.

Although he said that he was a fake fan, Lin Shu, a student with ulterior motives, felt that even if the favorability of fake fans was not too high, it would not be too low. It is of course impossible to be able to shake the boss's rough hand and then soar up in the daytime - the fairy world of the two courtyards!

Zhao Shiyuan obviously likes Lin Shu's insistence on running in the morning every day, because there are really very few students like Lin Shu now, and even he doesn't come to the morning run every day, only occasionally to exercise, but every day He can meet Lin Shu every time. It is conceivable how frequently Lin Shu runs in the morning. In his opinion, such a continuous persistence is very important in scientific research.

"After school starts, Lin Shu, you are going to prepare the subject, right? Have you found the subject?"

Lin Shu naturally replied very seriously to the inquiry from academician Zhao Shiyuan, saying: "Not yet, I plan to prepare my thesis after participating in the math-analog competition with my classmates."

Zhao Shiyuan frowned slightly, obviously dissatisfied with Lin Shu's participation in such competitions as mathematical modeling, and said: "It's better to spend more time on scientific research. Best grade."

Well, after hearing Zhao Shiyuan's words and looking at Zhao Shiyuan's frowning, Lin Shu didn't know if he had a favorability score of -1. Obviously, he could only nod repeatedly at this time.

"Teacher, you are right."

Zhao Shiyuan just mentioned this casually, and he also knew that it was understandable for students like Lin Shu to participate in mathematical modeling competitions, so he didn't say much, and went directly to exercise.

Lin Shu looked at the back of the academician, and thought in his heart that he could actually use the [Copy Glove] to copy the skills and experience of his mentor, but he felt that such a magical item should be used with caution, after all, it can copy the skills of an academician ——

Well, that picture is really too beautiful, I really dare not think about it...

After Lin Shuchen finished running, he went to the library to read and study. In the afternoon, he met Liu Zheng and Cheng Xu in the computer room.

Lin Shu has been reading books on mathematical modeling during this time, and he has also started to learn programming and algorithms. However, algorithm programming has too much professional knowledge, and it is still a hard bone for Lin Shu. There is no way that Lin Shu is really not Those geniuses in Huaqing, he is just an ordinary person who is willing to take the time to learn.

Obviously, Lin Shu underestimated his status as an ordinary person in the hearts of others.

"Lin Shu, I heard from Liu Zheng that you have been learning programming recently, or are you responsible for programming with me?"

When Lin Shu heard Cheng Xu's words, a line of words flashed across his head in an instant, didn't he just come here to win by paddling with his thighs in the water?

Why should he be in charge of programming together now?

Lin Shu looked at Liu Zheng, the meaning is self-evident, you have to give me an explanation.

Liu Zheng obviously knew Lin Shu's question, and said directly: "I think you are also responsible for programming in the early stage, so that you can understand the topic better, so that you can write the paper more smoothly later."

"..."

Lin Shu rolled his eyes. What he said, is it necessary to be responsible for modeling when writing a thesis?

"Then am I still in charge of modeling?"

"It would be better if you could."

Lin Shu looked at Liu Zheng, raised the corner of his mouth, and asked, "Is it okay if I quit?"

As soon as Liu Zheng heard what Lin Shu said, he hurriedly said: "Haha, don't, I'm just kidding, I just think Lin Shu is very strong, you can try to program together, don't you also have been learning programming now? ?”

"No way, you also know that our competition time will only be three days. After completing the mathematical modeling and programming, you must start writing the thesis immediately, so your time will be very tight. If you participate in the early stage, this may It will be faster."

"..."

Lin Shu suddenly felt that he was on a thief ship. Because it was a thief ship, this fleet didn't seem to welcome [Salted Fish Dead Corpse], and there was no place for the monster [Water Paddle Monster].

Lin Shu could only say: "I'll try my best to participate in the early stage, but don't expect too much."

"Okay, let's start training!"

Because it is a drill, it is necessary to prepare simulation topics. These are some topic simulations that Liu Zheng is looking for. Simulation training is carried out according to different directions, including data recovery and classification, communication networking, and statistical training...

Liu Zhengxian chose a statistical training topic for his simulation training:

The appendix lists the eight main variable data of the average per capita annual consumption expenditure of urban households in 31 provinces, municipalities and autonomous regions across the country in a certain year. Question 1: Using the shortest distance method, K-means method and two-step class method Cluster analysis by region; Question 2: Conduct principal component analysis and sort according to the first principal component; Question 3: Please find the average family size of urban residents and rural residents in the past 20 years in 31 provinces, municipalities and autonomous regions across the country. The annual expenditure data on entertainment, education and cultural services, and analyze whether urban residents and rural residents have any significant surprises; Question 4: Find the average per capita income of urban residents in the five cities of Yanjing, Mingzhu, Yangcheng, Pengcheng, and Xingcheng in the past 20 years. The annual expenditure data of entertainment, education and cultural services per person, and analyze whether there are any significant surprises; Question 5: Predict the annual entertainment, education and cultural services per capita of urban households in Star City in 2022,

NOTE: Please send your team's paper and results files to...

Although it is said here that he is in charge of the thesis, some things are not that simple. Naturally, they need to work together, especially his mathematics is not bad.

In Lin Shu's view, this is a statistical training. Statistics has always been a very important part of mathematical modeling, and this training problem can be completely implemented with SPSS. You can't keep staring at MATLAB and python. You also need to be aware of the The importance of SPSS.

Lin Shu's mathematics is not bad, so he and Liu Zheng did mathematical modeling together.

The first thing to do is data preprocessing. Assume that the 8 main variable data of 31 provinces and cities form a matrix with a size of 31x88. Due to the different dimensions of the selected indicators, some indicators with larger data will weaken the influence of indicators with smaller data. , before clustering the data, first standardize the original data to make the data obey the normal distribution...

...

In fact, mathematical modeling is more of a practical application problem. If only pure mathematical formulas are useless, the real difficulty is how to convert practical problems into mathematical problems, and this is mathematical modeling. After modeling, it is programming.

I have to say that it is not too difficult for Lin Shu and Liu Zheng to model together. As for the final decision on programming, Cheng Xu can handle it alone, and Lin Shu can try to start preparing the thesis——

Model building and solving

1.1 Modeling and solution of problem 1

1.1.1 Data preprocessing

...

I don't know if it's because the boss is very strong, or if he is paddling too obviously. In Lin Shu's opinion, this mock question is quite simple.

Time passed quietly, and the school will officially start soon, but for Lin Shu, it also means that the September math competition is approaching.

That is, when Lin Shu, Liu Zheng, and Cheng Xu were concentrating on preparing for the competition training, some unexpected things still happened.

Liu Zheng looked at Lin Shu and said, "Let's have dinner with Cheng Xu tonight."

Lin Shu nodded and said, "Okay, I just happen to have some questions and I want to ask him."

"Lin Shen, who is willing to answer questions, also has questions to ask others?"

Liu Zheng laughed and joked.

Hearing Liu Zheng's words, Lin Shu couldn't help smiling. He knew that because he often gave lectures enthusiastically to others, many juniors and other people thought he was very good, but in fact he was only doing it for clearing the request tasks. Just some experience value.

After all, if you answer it easily, you can squeeze a few strands of wool. If you don't squeeze it, you can't squeeze it, and if you squeeze it, you still want to squeeze it!

"The problem of algorithm programming, there is no way, the knowledge in this area is really difficult."

Liu Zheng gave Lin Shu a white look, and complained ruthlessly: "I don't think there is anything that can bother you. No matter how difficult a problem is, it is nothing to you."

"I've convinced you, it's really hard work."

Hearing Liu Zheng's words, Lin Shu could only say helplessly: "There is no way, the stupid bird can only fly first, and hard work can make up for its clumsiness."

"Your words will really hurt the relationship between us. If others hear you, you will really be scolded!"

"You are a pervert, a monster!"

Lin Shu smiled when he heard Liu Zheng complaining that he was a monster, and took this as a compliment.

There is no way, in Huaqing campus, a place where there are so many bullies and geniuses everywhere, Lin Shu's intelligence attribute is only disabled. If he can't be a genius, he can only try to be a monster.

"Wait for me, I'll call Cheng Xu."

Liu Zheng took out his mobile phone to call Cheng Xu, and said, "Tell him, let's go have dinner together."

Lin Shu nodded, and he started to pack his books and laptop first, and prepared to go back to the cafeteria with Liu Zheng. After a while, he saw Liu Zheng's expression changed, very solemn, as if something had happened.

"What did you say? How is it possible?"

Liu Zheng's eyes widened, he never expected to hear the news from Cheng Xu.

Lin Shu was puzzled in his heart. He didn't know what happened to make Liu Zheng so flustered, so he asked directly, "What's wrong? You have such an ugly expression?"

Liu Zheng hung up the phone in a panic, and then hurriedly said to Lin Shu: "Lin Shu, something happened."

"Yang Yu and his dormitory had an accident."

"What happened?"

Liu Zheng's expression was full of shock, his eyes widened, and he seemed to be unable to believe the news he just heard. He looked through the WeChat group with his mobile phone, and said in a trembling voice: "Just now Cheng Xu told me that Yang Yu used... ...stabbed Cao Man with a fruit knife, and now Cao Man...Cao Man has been sent to the hospital for emergency treatment."

Yang Yu stabbed Cao Man?

How can it be!

There is no doubt that Liu Zheng's words were definitely a thunderbolt, which made Lin Shu stunned.

What?

What a joke!

Lin Shu was stunned. He never expected such a situation, and really never expected it.

How could it be that Yang Yu stabbed Cao Man?

It shouldn't be!

Even if such a thing happened, Cao Man should have stabbed Yang Yu!

Lin Shucai clearly remembered the hideous face of Yang Yu who was poisoned to death in the time-space rift, with painful and unwilling eyes.

How could it be Yang Yu who stabbed Cao Man now?

Why is this happening?

Looking at the photos posted by his classmates in the WeChat group, Liu Zheng felt shocking. He was also shocked. It was really unbelievable. He handed the phone to Lin Shu and asked Lin Shu to see what terrible things happened.

Lin Shu took the mobile phone that Liu Zheng handed over, and only saw the blood-stained photos posted in the group. The bright red blood was stained on the ground. Someone also took a video photo of Cao Man being sent to the ambulance. There is a picture of Yang Yu's hands stained with blood.

The fruit knife was lying on the ground, red and bright.

Lin Shu felt a little dazed. He clearly saw Yang Yu being poisoned in the space-time rift. Why did Yang Yu stab Cao Man instead?

Lin Shu felt a little ridiculous and funny.

A chill came up just like that, sending chills down his spine.

The red blood in the photo is so dazzling, and amidst the noise in the video, it is not Yang Yu who is lying on the stretcher, but Cao Man.

Maybe it wasn't Cao Man who hid the beast in his body, or maybe it wasn't just Cao Man.

Maybe Yang Yu and Cao Man both have a fierce beast hidden in their bodies, and no one knows when the fierce beast will erupt and who will erupt first.

No one knows the answer, maybe Yang Yu walked past the cafeteria door with that black umbrella.

But at this moment, Lin Shu clearly knew that he was not the God who stopped everything, and he would not know the truth, nor could he truly understand people's hearts.

The different choices of people's hearts are the future of a moment.

Even God cannot completely decide to interfere with man's own choice.

A difference of thought is a different world.

What's more, he is not a god, nor does he have any priesthood skills. He has always been just an ordinary player without identity.

I hope you can support me a lot! ! grateful!
