Omnipotent Data

Chapter 387

"Look, what I said is true, right?" Cheng Nuo smiled.

"Great." Helmu nodded.

Hull was not surprised that it was a fake, but when he recalled the last time Cheng Nuo completed the outsourcing project in less than a week, the current situation can be regarded as the past.

Hull smiled bitterly. "It seems we all underestimated you."

Cheng Nuo was used to this for a long time, and said with a smile, "It seems that what I have hidden is not deep enough? Haha."

"Yes, that's the case..." Hull looked at Cheng Nuo with a hint of eagerness, "The exchange of tasks between the two of us is no longer feasible. Then, you can't give me some pointers. In terms of function theory, it is indeed It’s not my strength."

For this, Cheng Nuo did not hesitate.

He nodded. "Alright."

Hull’s task is to study the transformation relationship between some properties of Lipshitz function and 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.

So the thorny problem that Hull encountered was nothing in his eyes.

Putting down the work at hand, Cheng Nuo didn't need much thinking.

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

"Since our subject is related to Riemannian manifolds, the first task is to connect Lipshitz function and Riemannian manifolds to facilitate subsequent research."

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

f(y)-f(x)≤Lφ(y)-φ(x)

Then, it is obvious that f(x) satisfies the local Lipshitz condition near x0. the following,……"

"Look again, a mapping 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, subadditive, and all Satisfy f(x;v)≤Lv, f(x;v) as a function of v satisfies TxM..."

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

As time went by, his eyes became more and more bright.

A feeling of sudden realization filled his whole body.

All the confusion before, all disappeared without a trace.

Listening to your words is better than reading ten years!

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

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

Before he could react, Cheng Nuo felt that he was being hugged vigorously, 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, at five thirty-five, there were less than thirty minutes left before get off work.

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

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

"So tired!" Cheng Nuo stretched out a big lazy waist, looking at the red water surface in the distance as the setting sun soaked.

The Massachusetts Institute of Technology was built on the banks of the Charles River. Where Cheng Nuo's eyes are now, you can still see a few small boats floating on the river.

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

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

Raising his hand, just about to knock on the door, Cheng Nuo, who was fairly well-accepted, heard a few loud laughs coming from inside.

"Hahaha, hahahaha, hiccup~!"

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

"Come in!"

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

Seeing Cheng Nuo coming in, he suddenly looked straight and turned off the video that was playing on the computer.

He coughed slightly, his face was as usual, "Is there something wrong?"

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

"Your speed is fast!" Professor Fresnel took the U disk and praised with a smile.

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

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

"That's it..." Fresnel touched his chin, seeming to be thinking about something, glancing at Cheng Nuo from time to time.

An ominous premonition rose in Cheng Nuo's heart, tentatively speaking, "Professor, if there is nothing else, then I will go out?"

"Wait a minute." Professor Fresnel called Cheng Nuo.

He narrowed his eyes and said with a smile, "Your speed is something I didn't expect. However, it doesn't matter. I will arrange for you a task for the first phase of this project. The task of seeking the continuous mapping relationship between the two sequences will be handed over. Here you are!"

Cheng Nuo looked bitter, "Professor, this..."

That task was originally done by Professor Fresnel!

"Hey!" Professor Fresnel waved his hand and interrupted Cheng Nuo, "Don't thank me, you are an international friend, I should do more exercise for you!"

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

Sinister!

If I knew this, I didn't feel so anxious and went to Professor Fresnel to show off as soon as I finished the task.

This is not bad, not only that he is a "fast man", but also assigned to a task.

One more task, you don’t know how many more livers will be exploded!

If this continues, not only will the liver be insufficient, but even the kidneys will not be able to stand it!

If I knew so, why bother!

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

Looking at Cheng Nuo's bleakly walked back, Fresnel smiled slightly, "Boy, what a great job!"

…………

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

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

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

He Youjun glanced at Cheng Nuo diagonally, "Is it tired?"

Cheng Nuo didn't even have the strength to nod~www.readwn.com~ took a big project, and Professor Fresnel hurriedly assigned tasks to me. I can't wait to turn around for 24 hours! "

"For you, what are you looking at, so absorbed?" Cheng Nuo asked rhetorically.

"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 Go game, but both players playing chess are two robots.

One is the Alpha Dog who once became famous in World War I, and the other is a robot named Alpha Zero. I don't know where the robot came out suddenly.

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