Omnipotent Data

Chapter 387

Look, what I said is true, right? Cheng Nuo said with a smile.

Amazing. Hermione nodded.

Hull wasn't surprised that it was fake, but thinking back to the last time Cheng Nuo completed the outsourcing project by himself in less than a week, the situation in front of him was quite reasonable.

Hull smiled wryly, It seems that we all underestimated you.

Cheng Nuo has long been used to this, and said with a smile, It seems that I haven't hidden deep enough? Haha.

By the way, if that's the case... Hull looked at Cheng Nuo with a hint of eagerness, It's no longer feasible for the two of us to exchange tasks. Then, you can't give me some advice. In terms of function theory, it is true. It's not my forte.

This, Cheng Nuo did not hesitate.

He nodded, Alright.

Hull's task was to study the transformation relationship between some properties of the Lipshitz function and the FritzJohn-type optimality conditions, which he already knew when Professor Fresnel assigned the task.

Cheng Nuo's level of function theory is naturally higher than that of geometry.

Therefore, the thorny problem that Hull encountered was not a problem at all in his eyes.

Putting down the work in hand, Cheng Nuo didn't need to think for a long time.

A minute later, he picked up a piece of scratch paper and explained to Hull: The Lipshitz function is actually very simple, as long as you find the right cutting direction.

Since our subject is related to Riemannian manifolds, the first task is to connect the Lipshitz function with Riemannian manifolds to facilitate follow-up research.

My idea is, first, let f(x) be a real-valued function defined on a Riemannian manifold M, x0 ∈ U, (U, φ) be the coordinate card containing the point x0, if x, y ∈ U, and There exists a constant L with:

f(y)-f(x)≤Lφ(y)-φ(x)

Then, obviously, f(x) satisfies the local Lipshitz condition near x0. under,……

Look again, a map f:M→R satisfies the local Lipshitz condition near the point x∈M,

Then the mapping f(x;o):TxM→R is finite, positively homogeneous, sub-additive, and fully satisfies f(x;v)≤Lv, f(x;v) as a function of v satisfies in TxM ...

Hull sat beside Cheng Nuo, listening carefully to Cheng Nuo's explanation.

As time passed, his eyes became brighter and brighter.

A feeling of sudden enlightenment filled his whole body.

All the confusion before, all disappeared without a trace.

Listening to what you say is better than reading ten years of books!

If Hull stayed in China for a while, he would definitely use this idiom to express his inner excitement.

Okay, that's it. For the rest, you can go back and deduce it yourself. Cheng Nuo raised his pen and wrote down the last line of formula on the paper.

Before he had time to react, Cheng Nuo felt himself being hugged by a strong force, and then quickly let go.

When he looked up, it was Hull's back.

Cheng Nuo shook his head and smiled, turned his chair and continued to work.

…………

In the afternoon, it was 5:35, less than 30 minutes before the end of get off work.

Cheng Nuo, who had been sitting in front of the computer all day, stood up and moved his body while looking at the distant scenery through the window.

On the computer screen, Cheng Nuo had already completed his task, and put more than ten pages of formulas in a document.

I'm so tired! Cheng Nuo stretched his waist, looking at the red water surface dipped by the setting sun in the distance.

The Massachusetts Institute of Technology was established on the banks of the Charles River, and as far as Cheng Nuo could see, there were still a few small boats floating on the river.

When this project is over, you can go there for a stroll.

With that in mind, Cheng Nuo copied the files on the computer to a USB flash drive and walked to Professor Fresnel's office.

Raising his hand, Cheng Nuo, who was about to knock on the door, heard a few loud laughter from inside.

Hehehe, hahahaha, hiccup~!

After hesitating for a few seconds, Cheng Nuo still knocked on the door.

Come in!

Cheng Nuo pushed the door open, and saw Professor Fresnel leaning on his office chair, staring at the computer screen, stroking his beard, smiling happily.

Seeing Cheng Nuo coming in, he suddenly straightened his face and turned off the video that was playing on the computer.

With a light cough, his face remained normal, Is there something wrong?

Oh. Cheng Nuo handed over the USB flash drive and said, Professor Fresnel, I have finished the tasks you assigned me this morning, and the results and steps are all in the document on this USB flash drive.

Your speed is very fast! Professor Fresnel took the USB flash drive and praised with a smile.

But Cheng Nuo didn't think this was a compliment, he didn't want to be a fast guy!

Cheng Nuo waved his hand modestly, It's okay, so-so.

Is that so... Fresnel stroked his chin, as if he was thinking about something, and glanced at Cheng Nuo from time to time.

Cheng Nuo had an ominous premonition in his heart, and he tentatively asked, Professor, if there is nothing else, then I'll go out?

Wait a minute. Professor Fresnel stopped Cheng Nuo.

His eyes narrowed, and he said with a smile, I didn't expect your speed. But it doesn't matter. I will arrange another task for you in the first phase of this project. The job of finding the continuous mapping relationship between the two sequences will be handed over to you. Here you go!

Cheng Nuo looked bitter, Professor, this...

That task originally belonged to Professor Fresnel!

Hey! Professor Fresnel waved his hand and interrupted Cheng Nuo, You don't need to thank me, you are an international friend, I should do more to exercise you!

Cheng Nuo wanted to cry, but couldn't say anything.

Sin!

If I had known this earlier, I wouldn't be so anxious to come to Professor Fresnel to show off as soon as I finished the task.

This is good, not only does it show that he is a fast guy, but he is also assigned an extra task.

With one more task, I don't know how many more livers will be exploded!

If this continues, not only the liver will not be enough, but the kidneys will not be able to take it!

If I knew this earlier, why bother!

It seems that the great cause of kidney treasure should be put on the agenda earlier!

Looking at the back of Cheng Nuo who walked out bleakly, Fresnel smiled slightly, Boy, it's hard work for those who can!

…………

When I got home, it was already past nine in the evening.

He Youjun was very leisurely, wearing a bathrobe, half leaning on the sofa, staring at the TV while eating snacks.

Cheng Nuo also hurriedly washed up, threw himself on the sofa, and moaned softly, It's comfortable!

He Youjun glanced sideways at Cheng Nuo, Are you tired?

Cheng Nuo didn't even have the strength to nod his head, I took over a big project, and Professor Fresnel desperately assigns tasks to me. I can't wait to work around the clock!

For you, what are you looking at, so engrossed? Cheng Nuo asked back.

Go game. He Youjun said casually, and then added, Go game between robots.

Cheng Nuo looked at the TV screen curiously.

It is indeed a game of Go, but both sides of the game are two robots.

One is Alpha Dog who became famous in World War I, and the other is a robot named Alpha Zero. A robot that popped out of nowhere.

Looking at the chessboard, Cheng Nuo was a little surprised to find that AlphaGo, who once defeated the world's number one Go player, was indeed in a state of being beaten by Alpha Zero.
