In order to allow Ou Ye to fully understand his thinking logic, Shen Qi extended the original 100-word essay outline to 800-word.

During the outline revision process, Shen Qi and Ou Ye kept communicating.

Shen Qi: "In the main part of the paper, you need to transform two quadratic forms into square sums. You need to add a citation here. Do you know what to quote from Ou Ye?"

Ou Ye: "Butter."

Shen Qi: "Very good, you are making rapid progress. So when you summarize, you also need to quote it to correspond to the previous constant factor. Do you know what to quote?"

Ou Ye: "Collection."

Shen Qi: "It's very good, you are a smart girl."

The waiter added boiled water to Shen Qi, but he couldn't understand what Shen Qi and Ou Ye were talking about.

Ordinary college couples come to drink coffee. The most talked about topics are food, clothing, housing and transportation. Which store has delicious food? Kiss you, this dress is so beautiful and your temperament is particularly good. Let’s go out for a trip on Christmas, or just open a room locally, and so on.

The daily conversation between the young man and woman who drink boiled water belongs to another category. Are they either Shuimu or Yan University students?

Among his peers, only Ou Ye can understand Shen Qi's logic theory, and Ou Ye is slowly understanding it.

Only Shen Qi can grasp the core points of Ou Ye's language expression, and Shen Qi is gradually adapting.

In short, ordinary people can't understand the daily conversation between these two people. It's useless to understand. I don't know what they want to do or what their purpose is.

Shen Qi paid the bill and copied the outline of the paper into the U disk and handed it to Ou Ye: "I am going to go into seclusion. You will not see me within half a month to a month. The squad leader's work was entrusted to Zhou Yu'an. If there is anything particularly urgent, you can call me."

Ou Ye took over the USB flash drive and said: "The last thing."

Shen Qi said "Tell me."

Ou Ye: "Give me the handwritten manuscript for question 26."

Shen Qi still had no expression: "Oh."

Ou Ye: "You are crazy."

Shen Qi smiled and said nothing: "Ha."

"Haha." Ou Ye was amused by Shen Qi, and she showed a obvious smile, which was very obvious to her.

"Look, you smile very charmingly, and you even have two shallow dimples. Ou Ye, why do you always have expressionless faces? If you don't cry, laugh or be excited for a long time, it is easy to cause facial paralysis. In the future, you should smile more often, and do you hear it?" Shen Qi made a pertinent suggestion.

Ou Ye smiled and said nothing: "Oh."

"Ou Shen, I am not convinced by the environment and the local conditions, I will obey you. Your original version of 'Oh' is full of charm and I will never learn it in my life." Shen Qi stood up, shook his head with a smile, and went back to the dormitory to take a copy of the handwritten manuscript for question 26 and handed it to Ou Ye.

The handwritten manuscript records Shen Qi's initial logical ideas and answering process, and has certain reference significance for Ou Ye.

A few days later, Shen Qi entered seclusion mode. He left the dormitory at 6 a.m. and came back at 12 p.m. His roommates didn't know where he went or what he did.

In the process of sorting out the verification of question 23, Shen Qi encountered a new problem. He needed a new method to solve the generalized nonlinear complementarity problem of linear inequality constraints.

Shen Qi considered this question for three days and three nights, but it was fruitless and had no idea.

The original question of the 23rd question given by Sun Erxiong is not difficult, it is nothing more than just to prove a Jacobian determinant.

During the 48-hour crazy question-writing question, Shen Qi experienced the first thought-by-throw. He suddenly had a whim to assume a new proof method. After proving that this new proof method is established, he then went to verify the Jacobian determinant set up in the question.

In the past three days and three nights, Shen Qi has experienced a second ideological overturn. He believes that the new evidence he created before needs to be further improved, and the problem solving is OK, and there are many things worth pondering when writing a paper.

Continuously overturning, rebuilding, denying, and affirming that Shen Qi sat in a corner of Yanda for a day, for three days and three nights, except for eating, sleeping and going to the bathroom.

The biggest problem that troubles Shen Qi is whether there is an algorithm for the generalized Jacobian matrix of semi-smooth equation system composed of generalized complementarity problems to form a linearized quadratic model with ellipsoidal constraints?

A high-generation question that was not difficult was becoming more complicated by Shen Qi, and the more he thought about it, so profound that he could not answer it himself.

Mathematics and all natural sciences are moving forward in constant overthrow and re-argument.

Some people succeed and are famous in history.

Someone went crazy and sent to a mental hospital.

Shen Qi is hungry and he wants to have a meal.

He floated to the cafeteria in a daze, and Shen Qi lined up to wait for the meal.

While waiting for the meal, Shen Qi noticed that a large rectangular basin was placed inside the window, with many large white steamed buns in it.

These steamed buns accumulate in a strange way, showing obvious mathematical arrangement characteristics.

"It turns out that in addition to librarians and typists, there are also canteen masters." Shen Qi had to look at the food-making masters for a few more glances. His tall white hat highlighted his wisdom, and his bright eyes flashed with inspiration. He must be a master, and he must have had no choice but to live in Yan Da cafeteria.

It was Shen Qi's turn to serve the meal. He took out the meal card and faced the meal chef.

"Hello, classmate, what are you going to eat?" the master asked with a smile, which was particularly friendly.

Shen Qi was not in a hurry to order food. He pointed to the pile of steamed buns inside the window and said, "They are non-linear."

"That's absolute, classmate, of course, the big steamed buns are non-stuffed, and the stuffed buns are buns." The master answered and asked again: "How many steamed buns are made?"

Shen Qi humbly asked: "Master, which higher education institution did you graduate from and which master did you learn from?"

The master revealed his study experience: "I graduated from New Oriental Cooking School and the master who taught me that steaming buns is called Li Baota."

That's right, experts generally do not reveal their true identity easily. Shen Qi continued to test: "While you talk and laugh, you put forward the local nonlinear characteristic elements of the quadratic model at the xk point, and your theoretical foundation is very solid. Dormant in Yan Da Cafeteria, you must be studying some major topics and have some preliminary results?"

Okay, another pride of heaven was crazy. This is not a strange thing in Yanda. The master dared not ask too much. He focused on his catering career: "Young man, do you buy steamed buns?"

"Buy, buy five steamed buns." Shen Qi swiped the card and bought steamed buns.

After finding a table to sit down, Shen Qi ate a big steamed bun and tore it to pieces and left four.

Shen Qi's method of tearing steamed buns is very particular. It is obviously strictly calculated, and the size of each steamed bun fragment is almost the same.

The steamed bun fragments were arranged in three columns by Shen Qi, representing a certain matrix.

Observing the steamed bun matrix on a table, Shen Qi fell into a more confused logical deadlock. If ▽g(x)^-1▽f(x) is a p-matrix, then my previous assumptions are not valid?

Assuming that ▽g(x) is reversible, each of its principal formulas is non-negative, and each stable point of φ satisfies h(x)=0.

According to this logic, ▽g(x)^-1▽f(x) is a p-matrix defined in linear algebra, so is v∈h(x) non-singular?

There is an obvious logical error in this horse trampling, which makes no sense!

Shen Qi became more and more confused. The paper topic based on Question 23 became more and more profound. He proposed hypothesis, overturned the hypothesis, put forward it again, and overturned it again.

Logic is invincible, because it also requires the use of another logic to overcome logic. Shen Qi was trapped in a dead end of logical self-consistentness. He had never been so confused. He did not know that logic was a truly effective logic.

A student couple sat on the same dining table. They were loving and loving each other. You eat a piece of my stuffed tofu and I drink a sip of your milk tea.

The girl found Shen Qi not far away. She said to the man in curiosity: "It's so weird to see that person."

The boy glanced at Shen Qi and smiled cynically: "I saw it too. He looks like a dog, a math dog."

"How do you know he is from the Mathematical Academy?" the girl asked.

"I can recognize him to burn it to ashes, Shen Qi." The boy was in his sophomore year and majored in materials at the School of Engineering. He lost to Shen Qi in the 5000m competition not long ago: "Don't pay attention to him, he is a psychopath, and there is no normal person in the School of Mathematics. Come and have a meal. After eating, let's go to the movie."

The girl didn't go to the stadium to cheer for the engineering man. She didn't know Shen Qi before, but now she knows him.

While eating chicken wings picked up by a man's ticket, the girl couldn't help but take a look at Shen Qi. She thought that although this math dog was weird, he looked quite handsome and charming when he thought about problems seriously.
