I really don't want to lie down and win

Atomic scissors?

A new computer math graphics tool?

Never heard of it before!

Chen Li hurriedly downloaded this treatise. Although he hadn't read it carefully, he could tell from the previous part that this treatise was not simple. Afterwards, he checked the account information of the message and discovered many secrets.

"Magic City?"

"Or a woman?"

......

826章 难道是杨小曼？（3/3，月票加更51/85）

Midnight,

Chen Li sat in front of the computer and couldn't fall asleep for a long time. He was shocked by a thesis. This is a highly professional thesis. 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 1 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 1 random images, ordinary computers can't do this kind of processing at all, unless supercomputers are used.

And supercomputers are quite common in Shanghai. Apart from 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 of all,

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. It may be too early. There are some disappointments.

The emperor 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.

"Uh?"

"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 that you imagined yourself." Lao Xia said with a smile: "Speaking of...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."

"Yup!"

"That's right!" Lao Xia nodded, and said seriously: "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.

Then,

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 malice 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."

"Go, go, go!"

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

Chen Li nodded, and said seriously: "Yes! This talented person gave the latest unit of universal coverage area, and the following is her thesis collected in arXiv, which is about the latest research report on the unit of universal coverage area. "

"what?"

"Have you written a commentary?" 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 theory into the USB flash drive, you can read it on your computer." Chen Li handed Lao Xia a hard drive, and then stood beside him quietly, 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 horror, and the unbelievable expression, 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... amazing. It provides a very precise solution to the problem of universal coverage. As long as technology continues to improve, 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 definitely be discarded in the end, and a more high-end pruning tool is needed. Fortunately, the author provided his own ideas in the last part of the paper.

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 that this paper needs to rely on is not a computer like ours for daily work. It's... that kind of overcalculation."

"Correct!"

"I think so too. Processing 1 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 scope 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!"
