Genius Fundamentals - Chapter 177

The subgraph isomorphism is an np complete problem, and the graph isomorphism problem has not been proved to be a p or np problem so far.

She has probably heard some of this in the lectures that have been translated.

A staircase divides the building of the Department of Mathematics of Yongchuan University into two halves.

On the other half of the aisle, the workers were carrying cardboard boxes and cleaning up the office.

Lin Xixi looked at it for a while. In fact, she was very eager to find a detailed paper on computer search, but now she still has to focus on the immediate defense.

“Let’s go through the defense process again?” Lin turned his head and said to Lao Wang and A Guang.

The two looked awkward: “How do you become so fast?”

“Because I am a woman.” Lin Chaoxi replied absently.

Before entering the defense classroom, Lin Chaoxi was able to play with the old Wang Aguang, and when she pushed open the door of the defense classroom, she was mad at the forest, and she understood why Li Ran would cry.

There are two rows of teachers sitting under the stage. The actual number is not many. But each of them looks serious, and the old campus of Yongchuan University is dimly lit, and the window is covered by the ivy, so it is very repressive.

Lin Chaoxi had an expectation of the difficulty of the defense, so she didn’t feel too nervous. After paying tribute, she inserted the u disk and opened the ppt.

“Mr. teachers, good morning, our team number is 205912, the modeling contest is titled b: suspect tracking.

She has already practiced the lectures several times before, so she started the problem analysis and the theme.

After 7 minutes, she completed all the statements.

The stage was silent.

“It’s very familiar.” After a while, a famous female teacher looked up and said something faintly.

At the time, Lin Zhaoxi also received such an evaluation when he participated in the graduation thesis of the philosophy department. But their attitude towards the teacher and the current female teacher is completely different.

From the eyes of this female teacher, Lin Zhaoxi can see that she probably thinks that she is coming to praise.

“Because I have been preparing for a long time.” She answered seriously.

The female teacher’s eyes lowered and the brow wrinkled, which was very unpleasant: “That’s specifically about your modeling process for the second question.”

Lin eve back half a step, let the pharaoh go forward.

“It is like this, according to Bayes…”

When the voice of Lao Wang just started, he was interrupted: “What do you say, I let her answer.”

The female teacher looked harsh.

Li Ran had probably encountered such a situation just now, so he couldn’t say a word nervously.

“The overall mathematical modeling part was deduced by Wang Tianlong. Lin dynasty paused. “We think it would be more appropriate for him to answer.” ”

“If you are a member of the group, why don’t you understand the modeling formula? Even if you are just an ordinary mathematics student, you should be satisfied with the Bayesian formula.” The female teacher paused. “Your Sanwei University mathematics department is now What is your academic level?”

“They are better than me at my level, I am from the Department of Philosophy.” Lin said.

“Although the purpose of the competition did not clearly indicate that the award was not allowed, but now everyone in the modeling competition can participate?”

“What are you doing?” Pharaoh looked at her and suddenly asked.

“Reporting teacher, the whole paper structure was proposed by Lin Chaoxi. Our school philosophy department is not good, but it is still good. Her apprentice is also preparing for the postgraduate degree in mathematics. Awards.”

Pharaoh is hard to say a word seriously, but how to listen is like ridicule.

“Since the essay framework is what she did, why can’t the simplest model deduction be answered?” The female teacher suddenly looked very angry. “Philosophy is a graduate student in mathematics. You probably don’t know, mathematics and the humanities you have studied.” Different disciplines, it requires a lot of solid calculus and hard work. All the foundations are in my previous question, and I can’t understand it!”

“I understand.” Lin picked up the chalk in the evening, “I will answer it.”

She faces the blackboard and starts writing.

Although there must be one sentence on the Raiders, don’t clash with the teacher, but now it has already been done, and it is useless to say anything.

The overall model derivation is the part of Pharaoh’s responsibility, but these are familiar and unfamiliar to her.

Starting with the basic Bayesian formula, she wrote down all the modeling processes and even carefully completed many of the omitted parts of the paper.

It was no longer questioned, she also simply derived the algorithm they used.

These contents are actually very basic and cannot be said to be profound, but all proofs and derivations examine the degree of understanding of the problem.

Finally, she faced the chalk of a whole blackboard, put down the pen, and turned back.

Lao Wang and A Guang’s eyes were shining, secretly taking small hands in the place covered by the podium.

The teachers in the audience were half-headed, and although they did not speak, they did not have the indifference and carelessness in their eyes.

On the stage, it seems as if you are confrontational.

Finally, the female teacher who had previously answered her question pushed her glasses, as if she had reviewed all the answers, and she bowed her head and wrote a score.

Lin Chaoxi took a nap, packed up and prepared to leave.

“Wait, is Lin Xixi?”

Lin Chaoxi stopped all movements and followed the sound.

“The last one is a problem. Why do you want to transfer mathematics from the philosophy department? The senior suddenly decided to cross the exam. Don’t you think that your life is too casual?”

It was a middle-aged male teacher sitting in the last row of the classroom. His eyes were sharp and he could wear everything.

Lin Chaoxi licked his lips and wanted to answer something, but suddenly he did not know how to answer.

At that moment, she did not know what she was thinking, but suddenly wanted to know the answer of another person.

She took out WeChat, bowed her head and sent this question to Lao Lin under the podium.

“You may think that Teacher Zhang is too strict with you, but in our opinion, your attitude toward mathematics is too easy. You feel that it is a pleasing thing to jump from philosophy to mathematics with your own intelligence and wisdom, right?”

“No.” Lin refused.

“That answered me positively, do you like math?”

“I can’t talk about it or not.” Lin Chaoxi put the phone back in his pocket and looked up and said, “I didn’t choose mathematics. It was mathematics that chose me.”

——

Going out of the classroom and down the stairs, Lin sang and the workers carrying the cardboard boxes passed by.

Why did she turn to philosophy to learn mathematics? This is the question that many people have asked her after the second time in the world.

For her, there are too many inaccuracies in not being able to tell others.

But is there no answer in her heart?

Actually there is.

There is no reason, just because Lao Lin has trained her in this aspect since she was a child.

And when she came to the fork of life, she suddenly felt fearful about the future, and just got the chance to come back again, e=mc^2 pushed her to another path of life.

She seems to have just done this.

“You don’t want to be too upset.” Pharaoh patted her shoulder and called her back from the long memories. “It is common for the science and engineering male to look down on girls.”

Lin Chaoxi suddenly wanted to laugh: “Master, are you not a science man?”

“I am different. I am a man or a woman. I look down.”

“Master, why do you want to learn math?” Lin asked the old king.

“How can ordinary subjects meet the genius of being a teacher?”

“Only math can satisfy you?

“Of course, physics is barely ok.”

“You are too modest…”

The summer breeze noodles, the vines shake, and the mood of Lin Xixi suddenly improved.

In essence, the male teacher said that it is still to fight her, in fact, she does not have to care too much about what these people say.

After all, it is not a shame to admit that you are not the kind of person who knows what you are going to do by nature.

At this time, her cell phone shook.

Lin illuminates the screen and sees the information she just sent and the answer from Lao Lin.

– Dad, why did you want to learn mathematics?

– No reason, mathematics chose me.

Lin Zhaoxi held the phone and stopped in place.

After the sentence, Lao Lin also sent a look of “I am the best in the world.”

At that moment, she could almost imagine Lao Lin’s arrogant and arrogant face.

His answer is almost the same as her, but it is completely different.

Because Lao Lin’s answer is the true answer to the chosen genius.

Lin Chaoxi put the phone back in his pocket and looked back at the answering room just now. He only regretted it.

In a large number of universes, is there still a parallel time and space without her?

At the same time, the old forest of the world was one of the professors who sat under the podium and spurred the students. A second ago, he just finished a sip of water and is now ready to continue spraying.

In the same way, Lao Lin in that world has fulfilled all his wishes and ambitions and has a high academic achievement. In the present world, Lao Lin, who has been working for a long time to earn money to support her, is totally different.

It was almost at that time, Lin Chaoxi stepped down the last step.

Hundreds of cartons were laid under the steps, a truck stopped at the side of the building, and the workers were carrying things.

There are countless mathematics calculus papers and archival materials in the carton, most of which are obsolete.

The rough look is just an inconspicuous reorganization, but when you start to guess how many human thinking flashes will be recorded here, you will still be shocked.

Lin Chao swept through a cardboard box. The manuscript paper was a mathematical proof that she didn’t understand very well. At that time, she saw a string of numbers.

She also said that it was a coincidence that the fate was finally slipped to this moment.

The manuscript paper is written up – National Institute of Applied Mathematics, Yongchuan University.

The following is the address and contact information of the institute – 021-57632376.

At that time, she took two more steps to stop, and then I went back incredulously. I walked a few steps to the side of the carton and squatted down and confirmed it again.

021-57632376

Because of the age, the manuscript paper seems to be fragile, but the string number is as bright as blood.

In Anning City, the world of cheese, under a huge camphor tree, she saw a number of numbers in the fifth grade.

At that time, because of the sunshine, she did not see the last two, and therefore regarded it as a fate arrangement. There was not much Laolin’s past exploration.

At this moment, the sun is as dazzling as that day, and there is no such a scent on her head. But the huge puzzle replaces the shade of the tree to cover her.

Yongchuan University, Sanwei University… Laolin finally gave up what is mathematics for?

At that moment, Lin did not even need any calm time. She raised her head and asked the workers at the side of the carton: “This is the Department of Mathematics of Yongchuan University. What are you doing, where are you going to take things?”

“Going to the new campus, we are only responsible for moving things, what… I don’t know anything.”

Speaking of this, Lin Chaoxi was suddenly pulled and turned around, she saw Lu Zhihao’s doubtful face.

“What happened to you, what happened?”

Lin Chaoxi pulled Lu Zhihao’s arm: “Medical students are five years?”

“No, I have been studying for a total of eight years.”

“Then can you use the campus card? She said, while Lu Zhihao turned and ran.

“Where are you going, what?”

“Go to your school library archives.”
