Chapter 179: with you

Lin Zhaoxi felt that she was also very strange. Before she saw the "disposition," she was anxious and complicated.
She wants to know Lao Lin in the past, but does not want to listen too much to his father's past.
But now she passed the guidance of Lao Lin, and when she saw Lao Lin that was in the past, she suddenly calmed down. With a little anger, but more is calm.
First of all, she believes that Lao Lin will never be academically plagiarized.
Secondly, this is what Lao Lin asked her to find. Her father is so calm, she really has nothing to do with it.
The only problem is. What caused the "academic plagiarism" and "expulsion" of Lao Lin. This matter is related to the same graphic paper published by Professor Feng.
And Lao Lin’s call, in addition to calling the Secretariat, is still possible. He really called Professor Feng Deming, who was the director of the Institute.
Lin Zhaoxi took the pen to copy the key information, closed the old forest and personally pointed to the yearbook she came to, and put the book back to the bookshelf.
Then she got up and turned two laps, sorted out the ideas, and finally walked to the door.
When she walked out of the archives room, Lu Zhihao grabbed her: "What happened, what happened?"
"You have a bit more use of this sentence today."
"That's not that you are too strange!"
"I am normal." Lin said that there was a snack in the evening, and he thought about going upstairs for a few steps, and suddenly thought of something, and asked Lu Zhihao, "Is your school room upstairs?"
"No, on the first floor."
"Oh." Lin said at night, turning around and going down.
"You have to go to the computer room to check what?" Lu Zhihao quickly followed a few steps to follow.
"you guess?"
"You don't do this." Lu Zhihao began to bitterly, "I know that your heart is uncomfortable, you can not tell me, but don't lie."
Lin Zhaoxi: "?"
"Your father, not..."
"Oh, have you seen my WeChat?"
"I am not careful... I am sorry to see it."
"Well, my dad graduated from Yongchuan University, and then because of academic plagiarism, because the graduate student was fired." Lin dynasty paused, "This is the material I just turned over."
"I believe that your father will not be such a person!"
"How do you have more confidence than me?"
"Because your father taught you very well, and I have seen him, he is really smart and wise... although a little poisonous." The last few words are very quiet.
Lin smiled and smiled very much. He wanted to tell Lu Zhihao that you didn't read the old forest, and Lao Lin did not teach you the wrong.

Lin Zhaoxi followed Lu Zhihao to the computer room of Yongchuan University. Lu Zhihao used a campus card to open a computer for her.
The screen lit up, Lin opened the academic paper library, and she was very familiar with the blue and white interface.
She has used countless archives, sometimes even facing it all day, but never thought about checking the name of Lao Lin.
She is steady, holding the mouse, clicking on the search tag "author", and then entering the words "Lin Zhaosheng".
The page jumps and the cursor turns around.
The abstract of the title of the paper falls into the waterfall.
Agricultural economy, power industry, biology, physics, chemistry...
After all the unrelated subjects of the authors with the same name and the same name are omitted, only one subject of "mathematics" remains.
From 1988 to 1993, only one Lin Zhaosheng published a paper on mathematics, a total of seven papers. The publishing unit is the National Institute of Applied Mathematics of Yongchuan University, and several of them can be identified as Lao Lin himself.
From the graph theory to the optimization problem in discrete mathematics, from the exact graph isomorphism problem to its polynomial time algorithm, finally, Lin Zhaoxi saw an overview of the p/np problem written by Lao Lin.
She looked at the paper she was searching for and was silent for a while.
There is no such thing as Lao Lin being accused of academic plagiarism, but it can be seen from the research of existing papers that Laolin has long-term interest in graph isomorphism related issues.
Because of the age, she does not know how to measure the academic value of these papers, but the
reference amount
is obviously an important criterion.
"The amount of citations in this paper is a bit scary. Uncle Lin is really a pity."
Lu Zhihao sounded, and the title has changed from "your father" to "uncle Lin."
Lin Xixi could not respond. In fact, "it's a pity." "It's too regrettable." She has always had this idea since she was sensible.
It is now more real and intense to see Lao Lin’s true academic ability.
Even the scenes that appeared in her mind were so strong that Lao Lin took her to sit at the table and took her hand on the road. Lao Lin told her how wonderful mathematics is in a whimsical tone.
His love is so pure and pure, is it really forced to give up mathematics because of her appearance or the so-called academic plagiarism?
Will people like Lao Lin give up?
Once, when she gave Lao Lin a look at the modeling contest written on the blackboard, Lao Lin seemed to be very familiar with the research fields of Professor Zeng and Yu.
Later, he had a lot of questions about p/np.
Now, Lao Lin is accused of academic plagiarism papers and Professor Feng's papers published in arvix; the reasons why Professor Zeng tried to oppose this paper; and the "academic circle" she had not touched...
All kinds of clues and traces have made Lin’s glory in the midst of a meditation – Lao Lin may have given up mathematics for whatever reason, but maybe he never gave up?
She reorganized her thoughts, first downloaded the seven papers, opened arvix, and found Professor Feng Deming's graph isomorphism paper.
The paper was written in English and she read it carefully from beginning to end. There are a lot of professional vocabulary that she doesn't know and a proof process that she can't understand at all, but she has checked a few words and repeated several times of review. I understand that this paper is an npc problem in the argument that the graph isomorphism is a problem.
It was lunch time, Lin Chaoxi was immersed in the problem search, and when she looked up, she and Lu Zhihao were left in the computer room.
"How are you, you have to hurry up, there is still an hour of graduation, or if you don't check it first, let's go to your school first, and wait."
Lu Zhihao sneaked a bunch and looked anxious. Lin Qingxi pressed the Enter key and said to him: "Go ahead."
"Ah?" The boys screamed: "Isn't your graduation ceremony?"

Yes, oh,
Lin said, looking for more connections about graph isomorphism and p/np issues.
The relevant academic papers are so vast that she can't start.
"What's right!?" Lu Zhihao, "Hurry and go, these things are easy to check, don't delay the graduation ceremony."
"It doesn't matter." Lin squinted at the eye, unconsciously knocked a few mouse clicks, and the key to thinking about the problem.
Just then, she saw an academic news.
The graph isomorphism problem has a quasi-polynomial-level algorithm, and a major breakthrough in the p/np problem is the most important achievement in computer theory for 10 years.
Lin Chaoxi touched the phone on the computer desk, and even the screen was lit.
She looked at the name on the WeChat conversation interface. In addition to Lao Lin in the world, of course, there is a second person who can immediately answer his question.
However, she licked her lips and finally pressed the screen.
Since all the questions come from Lao Lin, it should still be answered by Lao Lin.
She packs all the content and sends it to her mailbox, then closes the browser and shuts down.
"You go to our school alone, I have something." She patted Lu Zhihao's shoulder and said.
"Where are you going?" Lu Zhihao made a shock.
"Go to my dad to have a meal." Lin Chaoxi directly interrupted a letter to Lao Lin - "At noon today, am I lucky enough to invite you to lunch and ask some academic questions?"
Lu Zhihao: "So, are we still going to send it together?"
Lin’s movements paused and I thought about it:
It’s just a long time since I had lunch.


There is a noodle shop next to the municipal hospital. At noon, the total flow of people is like a weaving. It takes a lot of effort to grab two window seats.
When the old forest arrived, the noodles and side dishes had come up, only a golden crispy fried platter.
Outside the window, the phoenix tree casts a shadow of a green tree. Lao Lin holds a large cardboard box and lays it on the ground and sits down.
"Sure enough, I know that my father is filial." He said that he directly took out the chopsticks and directly picked up the gold platoon.
Lin Chaoxi’s eyes are fast, and he uses the chopsticks to insert it.
"Zhang Xiufen, Li An'an, Chen Nature, Liu Liu, who are they?" She reported four names in one breath and observed the old forest reaction.
That is the list of the staff of the Secretariat of the Institute of Applied Mathematics of Yongchuan University on her small book. In her bracket, she chose the name to look like a woman.
"what?"

It’s not always Wang Qiang and Li Zhigao?!

"Who is this with whom, my dementia has worsened?"
Lao Lin’s expression is not like a fake.
"Oh, nothing." Lin Chaoxi silently crossed out the initial guess, these people should not have her mother, "That is not allowed to eat!" she said.
"Comrade Lin Chaoxi." Lao Lin suddenly had a low voice and a long heart.
"Ah?" Lin sighed in the heart.
"You may have forgotten one thing, even if you don't ask your old father to eat a big gold platoon, I also have the money to buy it myself."
Lin Zhaoxi: "..."
Lao Lin said that he raised his hand and signaled the waiter to come over.
Lin Chaoxi released the chopsticks, and the old Lin Meizi took the big row of mouths and asked: "Is the proof that the isomorphism belongs to the npc problem, and what is the important role in solving the p/np problem?"
Lao Lin was very difficult to get rid of, but recovered as usual after one second: "Hey, your recent thoughts are very delicate."

How come you see?

"The ability to analyze problems has a success for the father." Lao Lin only ate two large rows, and he was full of oil. "I don't ask what you mean by those names. You will talk about how you are from the father." Was expelled from this, think of the p/np problem?"
"Because the graph isomorphism is related to this question..."

Lin Zhaoxi’s classmates.
Lao Lin chewed the big row and shook the chopsticks.
The graduation thesis for the father’s alleged plagiarism is called
Theory and Methodology of Figure Isomorphic Verification.
This is first a graph theory problem. I can't find out, how did you connect it to p/np beyond 100,000 miles? Is there a lack of conditions?"
"..." Lin was speechless, she coughed, "I began to explain."
"please."

After the modeling contest, I went to the school mathematics department office and saw that Professor Zeng and another teacher were very serious about discussing the issue. I heard conversations that proved that the framework had problems. They later asked me to make a copy of the document. Directly cut off, I did not let me see the above content, but also reminded me of the 'academic circle' problem."
"Search inside the drop." Lao Lin nodded. "Not missing."
"I later heard that there is a grudge in the mathematics department of our university and Yongchuan University. Professor Zeng recently opposed Prof. Feng’s proof that the graph isomorphism belongs to the npc problem, so I pinched these questions together."
After Lin Chaoxi finished, sit upright: "Mr. Lin, I answered, please answer below."
"This way." Lao Lin said, "It's actually very simple. If the exact graph isomorphism problem proves to be an npc problem, and someone finds its polynomial time algorithm, then p=np."
Lao Lin said that he was arranging ribs and said in a consistently understated tone. The people around them were full of people, and the guests who ate in the noodle shop were still shouting "checkout", but Lin Linxi felt that the surroundings were suddenly silent.
"This means that the solution of that problem also means that human civilization will undergo a new, unprecedented, explosive development." Lao Lin said slowly.
Lin Chaoxi’s nose is the hot food aroma of the noodle shop. Everything is as usual, but she can’t help feeling the deep earthquake.
She barely put the chopsticks on the bowl, heard the slight lighter sound of the porcelain being hit, and her own voice: "Is this the reason you study the isomorphism?"
"The people who are interested in the p/np problem, who are trying to climb the peak, have never been Professor Zeng, Professor Feng or Yu." Lin looked at her father and suddenly felt that he was stupid. "These people I have always included you, right?"
Lao Lin smiled: "Yeah, I was finally discovered by you."
