Chapter 388: I have one sentence...

Chapter 388
"It's amazing!" Cheng Nuo picked up a piece of pastry on the coffee table and said with a smile.
He Youjun slowly said, "This is a new-generation product, and it can sling Alpha Dog after only three days of learning."
"It's a robot after all." Cheng Nuo said casually.
"Then you said, will humans defeat it in the future?" He Youjun asked.
"Perhaps." Cheng Nuo wiped his hands and got up from the sofa. "I was so tired today. I went to my room to sleep."
"Alpha Zero?" Closing the door, Cheng Nuo muttered to himself looking at the dark night outside the window.
………………
The next day was another day.
Opening the window, the fresh air didn't give Cheng Nuo any good mood.
After a night's rest, Cheng Nuo's spirit finally recovered a lot.
But when he thinks that there is still such a complicated task waiting for him today, he is overwhelmed.
"Cheng, good morning!"
"Good morning to you, Hull!"
Downstairs in the experiment, Cheng Nuo and Hull, who was walking in a hurry, met, greeted each other, and walked upstairs together.
Hull glanced at Cheng Nuo's face and wondered, "Why do you look so sad? Your progress, it shouldn't be difficult to complete the tasks assigned to you by the teacher within the specified time?"
The corner of Cheng Nuo's mouth twitched. Can I lift which pot without opening it?
He said with a heartache, "It's really not difficult. But when I was about to get off work yesterday, I handed over the tasks I had completed to Professor Fresnel."
"Then he sent me a more difficult task!" Cheng Nuo's tone was full of grief and anger!
Hull reacted for a few seconds, then he patted Cheng Nuo's shoulder hard and laughed.
"Hahahaha!" Hull laughed and tears were about to come out, "Brother, I sympathize with you very much. But I really can't help it, hahahaha!"
Cheng Nuo looked at Hull with a black line on his face and almost smiled and drew it over.
Hull didn't hold back his smile until he walked to the office door, "Cheng, don't be too sad! Those who can do more work. Since the teacher assigns you more tasks for reasons, it shows that he values ​​you! "
"A few other assistants except you, can't get this kind of treatment!"
With a bitter face, Cheng Nuo pushed open the door of the office, turned his head and said to Hull behind him, "If I can, I would rather not have this treatment."
Sitting at the desk, Cheng Nuo thought about his life for a few minutes, and saw Professor Fresnel walking in with a briefcase at the door, and hurriedly opened a new document on the computer.
The matter is a foregone conclusion, since you can't resist, then enjoy the process.
New task: continuous mapping between two sequences!
This is much more difficult than the basic concept that Cheng Nuo got before.
Originally, this should be Professor Fresnel's work, but who blamed Cheng Nuo for his own death, so this work fell on him.
Do it!
What else?
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 that exists under the continuous mapping of this series.
At first glance, it seems impossible to start, but after careful consideration, you will find that this is so special that there is no way 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 about it for more than ten minutes, Cheng Nuo rejected all several ideas.
Perhaps it is a good choice to ask Professor Fresnel with the question at this time. With his ability, he will certainly give Cheng Nuo a good advice.
But Cheng Nuo did not intend to do so.
It is a good thing to have a thigh in front of you, but it is not all a good thing. Holding thighs is to survive, not as a habit. Dependence is cultivated little by little in this way.
Moreover, Cheng Nuo has not yet reached a desperate situation. It’s not too late to ask Professor Fresnel if he hasn’t figured out how to solve this task by the end of get off work.
As for now, try to rely on yourself!
How can a man who pushes the king be stumped by a small mathematical problem?
Cheng Nuo closed his eyes, his thoughts flew in his mind.
vx=，f(x;o):TxM→R……
(X,y)一o=D一(X,y)^n……
…………
Suddenly, the corner of Cheng Nuo's mouth twitched.
Then his closed eyes opened, his tone excited, "I know what to do!"
Suppressing his inner excitement, Cheng Nuo tapped a line of formulas on the keyboard.
[Suppose (U, φ) is the coordinate card containing the point x, and xi∈B(x, δ) is U, because the mapping φ0, Pxx is a linear continuous mapping, when xi→x, vi→v:
φ-x(vi)→φ-x(v), φ-xi(vix)→φ-x(v)
From the upper semi-continuity of (f-φ^(-1))^α(φ(x);φ-x(v)), we can get:……】
Once the train of thought is opened up, Cheng Nuo will turn to the stray dog, ah! It's like a wild horse running off the rein, out of control!
…………
Four days later, Cheng Nuo pushed open the door of Professor Fresnel's cubicle in a nervous mood.
"Professor, after three days of unremitting efforts, I finally finished the task you gave me." Cheng Nuo put a USB flash drive on the desk and said carefully.
"Your speed is fast!" Professor Fresnel said the same thing as last time.
Some Cheng Nuo, who had nothing but soldiers, immediately felt tight.
Professor Fresnel saw Cheng Nuo nervously 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..."
"I'm talking about no more tasks for you in the first stage, but there are also tasks in the second stage that urgently need an assistant like you to do! Come and choose two, you're welcome, just pick it!" Professor Fresnel's face The spring breeze is gentle.
Cheng Nuo: "..."
He now has a sentence "Mom sells" ~EbookFREE.me~ I don't know if it should be said or not!
…………
Five days later, Cheng Nuo, who had already gotten a pair of dark circles under her 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 dumb, and he said fatefully, "Professor, tell me, what task will I be assigned this time?"
Professor Fresnel waved his hand, "Not this time."
There was a doubtful expression on Cheng Nuo's face.
Fresnel said, "This time it's really gone. You should have forgotten it. Tomorrow is the day when MIT graduate students start school. I will give you three days off."
"Tomorrow? School starts!" Cheng Nuo was taken aback, then reacted.
During this period of time, I have been so busy, I have forgotten even the important day of school!
