Chapter 387

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

"Awesome. Hermumu nodded.

Hel wasn't surprised that it was fake, but thinking back to the last time Cheng Nuo completed the outsourcing project on his own in less than a week, the current situation was considered to be in the past.

Hull smiled wryly, "Looks like we're all underestimating you." ”

Cheng Nuo has long been accustomed to this, and said with a smile, "It seems that I haven't hidden it deep enough?" ”

"By the way, then since that's the case......" Hull looked at Cheng Nuo with a hint of eagerness in his eyes, "It's no longer feasible for the two of us to exchange tasks." So, you can't give me a pointer, functional theory is really not my strong point. ”

Cheng Nuo did not hesitate to do this.

He nodded, "Okay." ”

Hull's task was to study some of the properties of the Lipschitz function and the transformational relations of the Fritz John-type optimality condition, which he had known to Professor Fresnel when he assigned the task.

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

So the thorny problems that Hull encountered were not a problem in his eyes at all.

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

A minute later, he picked up a piece of scratch paper and explained to Hull: "The Lipschitz function, as long as you get it right, is actually very simple. ”

"Since our topic is related to Riemannian manifolds, the first task is to link the Lipschitz function with Riemannian manifolds for subsequent research. ”

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

f(y)-f(x)|≤L|φ(y)-φ(x)|

It is clear, then, that f(x) satisfies the local Lipschitz condition around x0. ,...... below"

"If you see that a map f:M→R satisfies the local Lipschitz condition near the point x∈M, then the map f(x;o):TxM→R is finite, homogeneous, and can be added at the same time, and all satisfy |f(x;v)|≤L||v||, f(x;v) as a function of v satisfies ...... at TxM"

Hull sat beside Cheng Nuo and listened carefully to Cheng Nuo's explanation.

As time passed, his eyes grew brighter.

A feeling of sudden realization permeated his whole body.

All the confusion before disappeared without a trace.

Listening to your words is better than reading a book for ten years!

If Hull had been in China for a while, he would have used this idiom to express his inner excitement.

"Well, that's it. Later, you can go back and deduce it yourself. Cheng Nuo raised his pen and wrote the last line of formula on the paper.

Before he could react, Cheng Nuo felt that he was being held by a strong force, and then quickly let go.

When I looked up, it was already Hel's back.

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

............

In the afternoon, at 5:35, there were less than 30 minutes left before the end of 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 more than ten pages of formulas were put in a document.

"I'm so tired!" Cheng Nuo stretched his waist and looked at the red water in the distance under the sunset.

The Massachusetts Institute of Technology was built on the banks of the Charles River, and as far as Cheng Nuo's eye can see, you can still see a few small boats floating on the river.

When this project is over, you can go over there.

Thinking like this, Cheng Nuo copied the documents on the computer to a USB flash drive and walked to the door of Professor Fresnel's office.

Raising his hand, he just wanted to knock on the door, but Cheng Nuo, who was still hearing, heard a few laughs 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 and entered, and saw Professor Fresnel leaning on his office chair, staring at the computer screen, brushing his beard, and smiling happily.

Seeing Cheng Nuo come in, he suddenly turned pale and turned off the video that was playing on the computer.

Coughing lightly, his face was as usual, "Is there something wrong?"

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

"You're fast!" Professor Fresnel said with a smile as he took the USB stick.

But Cheng Nuo doesn't think this sentence is a compliment, he doesn't want to be a fast man!

Cheng Nuo waved his hand modestly, "It's okay, it's average." ”

"That's it......" Fresnel touched his chin, as if he was pondering something, and his eyes glanced at Cheng Nuo from time to time.

Cheng Nuo had an ominous premonition in his heart, and tentatively spoke, "Professor, if there is nothing else, then I will go out?"

"Wait a minute. Professor Fresnel called Cheng Nuo.

His eyes narrowed, and he said with a smile, "Your speed is something I didn't expect." However, it doesn't matter, I'll give you another task for the first phase of this project. I'll leave the work of finding the continuous mapping of two sequences to you!"

Cheng Nuo's face was bitter, "Professor, this ......"

That task was originally done by Professor Fresnel!

"Hey!" Professor Fresnel waved his hand and interrupted Cheng Nuo's words, "Don't thank me, you are an international friend, and exercising more is what I should do!"

Cheng Nuo wanted to cry without tears, he wanted to speak, but he couldn't say anything.

What a wickedness!

Knowing this, I was not in such a hurry to go 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 man", but he is also assigned one more task.

One more mission, I don't know how many livers will explode!

If this continues, not only will the liver not be enough, but even the kidneys won't be able to stand it!

If you knew this was the case, why bother in the first place!

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

Looking at Cheng Nuo's back walking out, Fresnel smiled slightly, "Boy, those who can work hard!"

............

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

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

Cheng Nuo also hurriedly washed up, threw himself on the sofa, and moaned softly, "Comfortable!"

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

Cheng Nuo didn't even have the strength to nod, "I took on a big project, and Professor Fresnel didn't want to assign tasks to me, I can't wait to rotate twenty-four hours a day!"

"To you, what do you see, so engrossed?" Cheng Nuo asked rhetorically.

"Go games. He Youjun said casually, and then added, "Go competition between robots." ”

Cheng Nuo looked at the TV screen curiously.

It was indeed a game of Go, but it was played by two robots on both sides.

One is an alpha dog who once became famous, and the other is a robot named alpha zero. A robot that suddenly appeared out of nowhere.

Looking at the chessboard, Cheng Nuo was a little surprised to find that the Alpha Dog, who had defeated the world's No. 1 Go player, was indeed in a state of being beaten by Alpha Zero.
