I Don’t Want to Win Lying Down

late at night,

Chen Li sat in front of the computer and couldn't fall asleep for a long time. He was shocked by a paper. This is a highly professional paper. Coverage problems are now calculated by computer, but only this author has provided a brand new tool.

Atomic scissors...Cut the area at the atomic level. Although this idea has been around for a long time, it was later found that the difficulty is not so high, but the author did it. Using the overlay shapes of 10,000 images as clues, looking for Can area.

obviously,

This method is very limited, successfully reduced to 0.84409359 square units, and Chen Li noticed a problem, that is, the 10,000 random images, ordinary computers can't do this kind of processing, unless supercomputers are used.

And supercomputers are quite common in Shanghai. Except for Fuda owning one, the rest are Jiaotong University and Jida University. Could it be that this female mathematician is a teacher of the three schools?

first,

Fuda has been ruled out, and the rest are Jiaotong University and Jida University. Chen Li really wants to call his friends at this time and ask if there are any female mathematicians in Jiaotong University and Jida University, but there is also a possibility. The mysterious author is a Ph.D. in mathematics.

In short, Chen Li couldn't fall asleep that night.

the next day,

Chen Li went to the school, and at the same time brought yesterday's gains to the general office of the Department of Mathematics. Maybe he came too early. There are some disappointments.

Heaven pays off,

Finally, when a colleague came to work, Chen Li hurriedly shouted to his colleague: Old Xia! I met a talented person on the Internet yesterday. She solved a difficult point in the universal coverage problem and invented A whole new pruning tool.

Lao Xia's full name is Xia Jiguang. He is a Ph.D. student in the Mathematics Department of Fuda University. He is also the person in charge of a certain project.

Well?

Meet on the Internet? Lao Xia frowned, and asked with a confused look on his face: Is the Internet reliable or not? Maybe it's a liar, Xiao Chen...you won't be cheated, right? ? There are so many boring people these days, I have been fooled a few times before.

No no no!

Absolutely don't believe me! Xu Mang said seriously: She has a very powerful mathematical research ability, and also masters superb computer technology. She used the computer to construct a model of her universal coverage problem, and then used A whole new tool for pruning.

...

Why do I sound like bragging, or a plot you imagined yourself. Lao Xia said with a smile: By the way... what's going on?

real!

I met a mathematician on the Internet, and he is also from Shanghai, and his gender is female. Chen Li knew that it was useless to talk too much, so he took out his mobile phone and found the message sent by that one. Weibo.

This is a question I provided on the Internet, about universal coverage. Chen Li said, Then I guided the question to the limit value of universal coverage, and told everyone that 0.8441153 is a value that cannot be reduced temporarily. Unit area.

yes!

That's right! Lao Xia nodded,

Seriously said: On the issue of universal coverage, 0.8441153 is indeed a unit area that cannot be reduced at present. Of course, it may be possible in the future...but it is currently impossible.

Chen Li smiled wryly, and said helplessly: I have the same idea as you, and I used this idea to instill it in everyone. As a result... I was severely educated, it's shameful... Now I think about it. I feel regretful.

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

Immediately afterwards,

Chen Li found a certain message, which criticized him without any hesitation, without leaving any sympathy at all, followed by a set of numbers and a link to a website, and then handed the phone to Lao Xia, With a bitter smile, he said, Old Xia, you can see for yourself.

took the phone,

Lao Xia read it carefully. He felt maliciousness from this passage. There was a thorn in the words, and there was no empathy at all. In terms of position, Chen Li was educated ideologically.

this...

What does this guy say. Lao Xia frowned, and said seriously: It makes me feel that there is some pretentiousness, no matter whether he is really powerful or not, but I am very dissatisfied with his arrogant attitude. , even if this person is a genius, it is nothing compared to Professor Xu.

...

Professor Xu...Old Xia! Chen Li said helplessly, You're a bit of a bully, and we can't talk about it anymore.

All right, all right!

We don't involve Professor Xu, let's say... the number behind this is the latest area unit covered by the universe? Lao Xia asked: And the website link behind this... will not be a document pre-collected by arXiv website?

Chen Li nodded, and said seriously: Yes! This talented person gave the latest universal coverage area unit, and the following is her paper included in arXiv, which is a research paper on the latest universal coverage area unit.

What?

Already wrote a paper? Lao Xia was stunned for a moment, and said in surprise: It's interesting... By the way, can you click in and have a look?

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

After getting the U disk,

Immediately plugged it into the computer, found the document, clicked on it and read it carefully, and then... the eyes were radiating with horror, and the expression of disbelief, the mouth was slightly opened, but I didn't know what I wanted to say What.

after all,

At this moment, there is only one thing on Lao Xiaman's mind. This paper is simply... simply amazing. It provides a very precise solution to the problem of universal coverage. As long as technology continues to advance, it will be able to It is always shrinking the limit theory of universal coverage.

The core of this key method is a pruning tool, but Lao Xia feels that the atomic scissors will be discarded in the end, and a more high-end pruning tool is needed. 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 feel something is wrong! Lao Xia came back to his senses and said seriously: This is definitely not an ordinary person, and the computer needed for this paper is not a computer like our daily work. It's... that kind of overcalculation.

right!

I think so too. Processing 10,000 random images at the same time and trimming them in that way is simply impossible for ordinary computers. Chen Li said, Only supercomputers...so give us the range to find her. Shrunk down a lot.

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

The physics department has access to supercomputing, and the mathematics of the physics department is also very good. Chen Li continued: Professor Xu is a typical example.

...

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

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

maybe.

Lao Xia glanced at Chen Li and asked curiously, Why don't you ask her online?

asked...

In the end, they didn't reply to me. Chen Li smiled wryly.

You can always find some clues if you look for the Weibo posted by this person, Lao Xia said.

good!

after,

Chen Li spent the whole morning flipping through the microblogs posted by that microblog account, but his expectations were in vain. Basically, this mysterious person never posted a single microblog, but only reposted other people's microblogs. And it's all news about semiconductor materials.

However, Chen Li also discovered some small problems. All the forwarded content was semiconductor materials, but they all pointed to a company...Xu Yang Company.

Could it be...

Is this mysterious person an employee of Xu Yang's company? Isn't she a doctor or professor at Fuda?

All kinds of doubts flooded his mind, making Chen Li a little uncomfortable. He really wanted to know the truth. The kind of thirst for knowledge that scratched his heart and liver, said that this young doctor of mathematics was tortured so much that he wished to smash him to death with a piece of tofu.

at noon,

Almost everyone in the office knew about this mysterious man and joined in the search for the truth, but unfortunately... nothing was found.

well?

Wait a minute...I...I found something strange. A young female doctor said in horror: Look...the content she forwarded has many people leaving comments, but the content of these comments is very It's strange, it's not that kind of ridicule, but a kind of respectful congratulations, and they are all employees of Xu Yang's company without exception.

strangeness...

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

oh!

Xu Yang's company...isn't it the company of Professor Xu's wife? I remember the rumors are like this. A young man present said, It's called...Yang...Yang, what is it?

Yang Xiaoman! Someone in the office reminded: Miss Yang Hong Group's daughter is also the first place in the PUMaC mathematics competition, and a Ph.D. in the Department of Economics... Like Professor Xu, she is a genius among geniuses. .”

...

...

...

etc,

First place in PUMaC math competition?

PhD in economics?

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

this moment,

The entire office was filled with an atmosphere of silence, and everyone present had a terrible idea. This mysterious genius who solved the universal coverage problem was actually Professor Xu's wife, the boss of Xu Yang Company... Yang Xiaoman !

I...

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