Chapter 388

"It's amazing!" Cheng Nuo picked up a piece of pastry on the coffee table and said with a smile.

He Youjun said slowly, "This is a new generation of products, and you can beat the alpha dog after only three days of learning." ”

"It's robots, after all. Cheng Nuo said casually.

"Then you say, will humans defeat it in the future?" He Youjun asked.

"Maybe. Cheng Nuo wiped his hands and got up from the sofa, "I'm too tired today, go back to my room and sleep." ”

"Alpha zero?" Closing the door, Cheng Nuo looked at the dark night outside the window and muttered to himself.

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

The next day, it was a new day.

Pushing open the window, the fresh air did not bring Cheng Nuo any good mood.

After a night's rest, Cheng Nuo's spirit finally recovered a lot.

But when he thought that there was such a complicated task waiting for him today, he couldn't do it.

"Cheng, good morning!"

"Good morning, Hull, too!"

Downstairs in the experiment, Cheng Nuo and Hull who were in a hurry met, said hello to each other, and walked upstairs together.

Hull glanced at Cheng Nuo's face and wondered, "Why do you look sad? Your progress, it shouldn't be difficult to complete the task assigned to you by the teacher within the specified time, right?"

The corners of Cheng Nuo's mouth twitched violently. Can you not open which pot to mention?

He said bitterly, "It's really not difficult. But yesterday, when I was about to leave work, I handed over the task to Professor Fresnel. ”

"Then, he sent me an even more difficult task!" Cheng Nuo's tone was filled with grief and indignation!

Hull reacted for a few seconds, then patted Cheng Nuo's shoulder vigorously and laughed.

"Hahahaha!" Hull laughed with tears coming out, "Brother, I sympathize with your plight. But I can't help it, hahahaha!"

Cheng Nuo looked at Hull with a black line on his face, and almost laughed and sneered directly.

It wasn't until he walked to the door of the office that Hull couldn't hold back a smile, "Cheng, don't be too sad!

"Except for you, the other assistants don't get this kind of treatment!"

Cheng Nuo made a bitter face, pushed open the office door, turned his head and said to Hull behind him, "If I could, I'd rather not have this kind of treatment." ”

Sitting at the desk, Cheng Nuo thought about his life for a few minutes, and saw Professor Fresnel walk in with a briefcase at the door, and hurriedly opened a new document on the computer.

It's a foregone conclusion, and since you can't resist it, enjoy the process.

New Task: Continuous Mapping of Two Sequences!

This is much more difficult than the setting of the basic concept that Cheng Nuo got before.

Originally, this should be Professor Fresnel's work, but who blames Cheng Nuo for his own death, so this work fell on his head.

Let's go!

What else can you do?

After adjusting his mentality, Cheng Nuo began to sort out the context of the task.

The so-called two sequences refer to the two sequences xi∈B(x,δ) and vi∈TxM.

What needs to be solved is the derivation relationship between the successive sequences under the continuous mapping.

At first glance, it seems that there is no way to start, but after careful consideration, you will find that this special thing is impossible to start!

In terms of mathematical attainments, Cheng Nuo is far inferior to Professor Fresnel.

Therefore, this task, which belonged to Professor Fresnel, also faced a very difficult situation.

After thinking for more than ten minutes, several ideas were all denied by Cheng Nuo one after another.

Maybe it's a good choice to ask Professor Fresnel about the topic at this time, and with his ability, he will definitely give Cheng Nuo a good point.

But Cheng Nuo didn't plan to do that.

It's good to have a thigh standing in front of you, but it's not all good. Hugging your thighs is for survival, not as a habit. This is how the psychology of dependence is cultivated little by little.

Moreover, Cheng Nuo has not yet reached a desperate situation. If he hadn't figured out how to solve the task by the time he got off work, it wouldn't be too late to consult Professor Fresnel.

For now, let's try to be on your own!

How can a man who forces the king be stumped by a small math problem?

Cheng Nuo closed his eyes, and thoughts flew in his mind.

v||x=，f(x;o):TxM→R......

(X,y)-o=D-a(X,y)^n......

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

Suddenly, the corners of Cheng Nuo's mouth curled.

Then his closed eyes opened, and his tone was excited, "I know how to do it!"

Suppressing the excitement in his heart, Cheng Nuo clicked out a line of formulas on the keyboard.

[Let (U,φ) be the coordinate card containing the point x, and xi∈B(x,δ) 匚U, because the mapping φ0, Pxx is a linear continuous map, when xi→x, vi→v has:

φ-x(vi)→φ-x(v)，φ-xi(vix)→φ-x(v)

by (f-φ^(-1))^α(φ(x); φ-x(v)) can be obtained: ......]

Once the train of thought is cleared, Cheng Nuo will go to the wild dog that has escaped, ahh

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

Four days later, Cheng Nuo pushed open the door of Professor Fresnel's cubicle with apprehension.

"Professor, after three days of unremitting efforts, I have finally completed the task you gave me. Cheng Nuo put a USB flash drive on his desk and said carefully.

"You're fast!" Professor Fresnel said the same thing as last time.

Cheng Nuo, who was a soldier, immediately tightened his heart.

Professor Fresnel looked at Cheng Nuo's nervous appearance, and waved his hand with a smile, "Don't be so nervous, don't worry, after this task is completed, I won't send you another task in the first stage." ”

"That's great!" Cheng Nuo patted his chest.

Professor Fresnel continued with a warm smile and beckoned, "Cheng Nuo, come here, I have a new task for you." ”

Cheng Nuo was stunned, "Professor, didn't you mean ......"

"What I'm saying is that you won't be assigned tasks in the first stage, but there are still tasks in the second stage that urgently need assistants like you to do! Come and choose two, you're welcome, just pick and choose!" Professor Fresnel's face was warm.

Cheng Nuo: "......"

He now has a sentence that his mother sells criticism, and he doesn't know whether to say it or not!

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

Five days later, Cheng Nuo, who had already boiled out a pair of dark circles under his eyes, handed a USB flash drive to Professor Fresnel.

Professor Fresnel smiled and looked at Cheng Nuo, "Your speed is very fast!"

Cheng Nuo's face was blank, and he said in resignation, "Professor, tell me, what task will be assigned to me this time?"

Professor Fresnel waved his hand, "Not this time." ”

Cheng Nuo had a skeptical expression on his face.

Fresnel began, "Not this time. You should have forgotten that tomorrow is the opening day of MIT graduate students, and you will be given three days off. ”

"Tomorrow, school starts!" Cheng Nuo was stunned for a moment, and then reacted.

During this time, I was so busy that I even forgot about the important day of school!
