late at night

Chen Li sat in front of the computer and couldn't fall asleep, he was shocked by a paper, this is a highly professional paper, the author of the paper not only has super high mathematical research ability, but also proficient in computers, although all coverage problems are now calculated by computers, but this author provides a new tool.

Atomic Scissors... Although the idea of cropping the atomic area has been around for a long time, it was later found that the difficulty is not usually high, but the author did it, using the covering shape of 10,000 images as a clue to find the possible area.

Obviously,

This method was very limited, and it was successfully reduced to 0.84409359 square units, and Chen Li noticed a problem, that is, the 10,000 random images, ordinary computers could not do this kind of processing, unless using supercomputers.

And supercomputers are not uncommon in the magic capital, except for Fuda has one, the rest are Jiaotong University and Jida University, is this female mathematician a teacher in three schools?

First of all

Chen Li would like to call his friends at this time to ask if there are any female mathematicians in Jiaotong University and Jiji University, but there is also a possibility that the mysterious author is a doctor of mathematics.

In short, this night, Chen Li couldn't sleep.

Following

Chen Li went to the school, and at the same time came to the comprehensive office of the Department of Mathematics with yesterday's harvest, it may have come too early, the office was empty at this time, and there was a backlog of excitement for a night without an outlet, which made Chen Li a little disappointed.

The emperor lives up to his wishes,

Finally, when a colleague came to work, Chen Li hurriedly shouted at his colleague: "Lao Xia! I met a cow man on the Internet yesterday, she solved a difficult problem of universal coverage, and invented a new pruning tool. ”

Lao Xia, whose full name is Xia Aurora, is a Ph.D. in the Department of Mathematics of Fudan University, and is also the person in charge of a project, and has very old qualifications in the Department of Mathematics of Fudan University.

"Huh?"

"Met on the Internet?" Lao Xia frowned, and asked with a confused expression: "Is it reliable on the Internet?" Maybe it's a liar, Xiao Chen... You're not going to be deceived, are you? There are a lot of boring people these days, and I've been fooled a few times before. ”

"No, no, no!"

"Definitely not believe me!" Xu Mang said seriously: "She has a very strong mathematical research ability, and at the same time has mastered superb computer technology, she used the computer to model her universal coverage problem, and then used a new tool to prune it." ”

“...”

"How I sound like bragging, or your own fantasy. Lao Xia smiled and said, "Anyway... What the hell is going on?"

"Really!"

"I met a math awesome guy on the Internet, and he was from our Modu, and his gender was female. Chen Li knew that it was useless to say more, so he directly took out his mobile phone and found the Weibo that he posted.

"This is a question that I offer online, about universal coverage. Chen Li said: "Then I guided the problem to the limit value of universal coverage, and told everyone that 0.8441153 is a unit area that cannot be reduced for the time being. ”

"That's right!"

"That's right!" Lao Xia nodded and said seriously: "In terms of universal coverage, 0.8441153 is indeed a unit area that cannot be reduced at present, of course, it is possible in the future... But not at the moment. ”

Chen Li smiled bitterly and said helplessly: "I have the same idea as you, and I use this idea to instill it in everyone, and as a result... I've been taught so badly, shame on you... I regret it now when I think about it. ”

Lao Xia was stunned when he heard this, he was completely confused, he felt that Xiao Chen today was very strange, all kinds of behaviors were very weird, and some of the words in his mouth were also confusing.

Followed by

Chen Li flipped out a certain message, the content on which criticized him without hesitation, leaving no emotion at all, followed by a set of numbers and a website connection, and then handed the mobile phone to Lao Xia, and said with a wry smile: "Lao Xia, look at it yourself." ”

Took the phone,

Lao Xia read it carefully, he felt the malice from this paragraph, there was a thorn in the words, and he didn't leave any emotion at all, but when he looked back and read it again, he couldn't help but find that the other party was standing in a very high position and had carried out ideological education on Chen Li.

"This..."

"What does this guy say? Lao Xia frowned and said seriously: "It makes me feel that there is some pretending garlic, whether it is really powerful or not, but the arrogant attitude he showed, I am very dissatisfied when I see it, even if this person is a genius, it is nothing compared to Professor Xu." ”

“...”

"Professor Xu... Lao Xia!" Chen Li said helplessly: "You are a little bit of a bully, this is not going on at all." ”

"Okay, okay!"

"We don't involve Professor Xu, to speak... This number behind this is the latest unit of area covered by Wanyou?" Lao Xia asked, "And the website link behind this... It can't be a pre-documentation site for arXiv, right?"

Chen Li nodded and said solemnly: "Yes, this bull gave the latest universal coverage area unit, and the back is her paper in arXiv, which is about the latest universal coverage area unit research report paper. ”

"What?"

"Have you written a paper?" Lao Xia was stunned for a moment, and said in surprise: "It's a bit interesting... Anyway, can you click in and have a look?"

"I downloaded the paper to a USB flash drive, and you can read it on the computer yourself. Chen Li handed Lao Xia a hard drive, and then stood quietly beside him, waiting for the moment when Lao Xia witnessed the miracle.

After getting the USB flash drive,

Immediately plugged into the computer, found the file, clicked on it and read it carefully, and then... His eyes glowed with horror and disbelief, and his mouth was slightly open, but he didn't know what to say.

After all

At this moment, Lao Xia is full of only one thing in his mind, this paper is simply... It's simply amazing, and it provides a very precise solution to the problem of universal coverage, and as long as the technology continues to advance, it can continue to shrink into the limit theory of universal coverage.

And the core of this key method is a pruning tool, but Lao Xia felt that the atomic scissors would be abandoned in the end, and a more high-end pruning tool was needed, but fortunately, in the last part of the paper, the author provided his own ideas.

Subatomic scissors...

Just hearing the name makes me feel amazing!

"Xiao Chen... I think something is wrong!" Lao Xia came back to his senses and said seriously: "This is definitely not an ordinary person, and the computer that this paper needs to use is not a computer like ours for daily work, but... That kind of supercomputing. ”

"Yes!"

"That's what I think, processing 10,000 random images at the same time, and trimming them in that way, is impossible for a normal computer to do. Chen Li said: "Only supercalculation... So the scope for us to find her has narrowed down a lot. ”

"We have one at Fuda, one at Jida, and one at Jiaotong University. Chen Li said: "I thought about it for a long time last night... I think this mysterious person, she may be from our Fuda University, and finally she may be from the physics department!"

"The physics department has access to supercomputing, and at the same time, the physics department is also very good at mathematics. Chen Li continued: "A typical example is Professor Xu. ”

“...”

"You didn't let me mention Professor Xu, why did you mention it yourself?" asked Lao Xia.

"Now that you can mention it, what do you think of my guess?"

"Perhaps. ”

Lao Xia glanced at Chen Li and asked curiously, "Why don't you ask her on the Internet?"

"Asked..."

"I didn't get back to me. Chen Li smiled bitterly.

"If you look for this person's Weibo, you can always find some clues. Lao Xia said.

"Good!"

afterwards

Chen Li spent a morning flipping through the Weibo account posted Weibo, but his expectations were disappointed, basically the mysterious person did not post a single Weibo, all of them were reposting other people's Weibo, and they were all news about semiconductor materials.

But Chen Li also found some small problems, the content of the retweets was all semiconductor materials, but they all pointed to a company... Xu Yang Company.

Don't...

This mysterious person is an employee of Xu Yang's company, and she is not a doctor or professor at Fuda?

All kinds of doubts filled his brain, making Chen Li a little uncomfortable, he really wanted to know the truth, that kind of curiosity to scratch his heart, saying that this young doctor of mathematics was tortured enough, and he wanted to take a piece of tofu and kill him.

At noon,

Almost the entire office knows about this mysterious person, and they have joined the search for the truth, but alas... Nothing.

"Huh?"

"Wait a minute... I... I found something strange. A young female doctor said in horror, "Look... There are many messages on the content she forwarded, but the content of these messages is very strange, not that kind of ridicule, but a kind of respectful congratulations, and without exception they are all employees of Xu Yang's company. ”

"Strange..."

"Could it be that this mysterious person is a senior executive of Xu Yang's company?" the young female doctor asked.

"Oh!"

"Xu Yang Company... Isn't it Professor Xu's wife's company? I remember the rumors were like this. One of the young men present said, "Called... Poplar... What is Yang?"

"Yang Xiaoman!" a certain person in the office reminded: "Miss Yang Hong Group's daughter, who is also the first place winner in the PUMaC Mathematics Competition, and a Ph.D. in the Department of Economics... Like Professor Xu, he is a genius among geniuses. ”

“...”

“...”

“...”

Wait a minute

1st place in PUMaC Mathematics Competition?

Ph.D. in the Faculty of Economics?

This... That shouldn't be possible, right?

At this moment,

There was a silent atmosphere in the whole office, and everyone present had a terrible idea, this mysterious genius who solved the problem of universal coverage was actually Professor Xu's wife, the CEO of Xu Yang's company... Yang Xiaoman!

"I..."

"We should think of the same person, right?" Chen Li asked in horror, "Do you think it's also Yang Xiaoman?"

......
