Chapter 390

Chapter 393

in the end, Cheng Nuo did not resist Jiang Li's bitter request and reluctantly agreed to participate in the go game half a month later.

If Cheng Nuo can make it to the final, it will take three days.

Fortunately, we don't have to stay there all day long. If we make some adjustments, we won't have a big impact on Cheng Nuo's arrangement.

At the thought of the International Conference of mathematicians to be held a month later, Cheng Nuo was excited!

Although Professor Fresnel gave Cheng Nuo a three-day holiday, he returned to the office the next day after the school started.

"Why don't you have a few more days off?" Asked Professor Cheney with a smile.

Cheng Nuo shook his head, "no, I'm full of energy now. Professor, if there is any task that I can do, please give it to me as much as possible! "

Cheng Nuo held his head high, and his appearance was completely a look of ravaging me with project tasks.

This time it was Professor Fresnel's turn.

Is it because of too many tasks and too much pressure for Cheng Nuo some time ago, this child has become shaking M.

Professor Fresnel stood up with a rare kind smile on his face, "Mr. Cheng Nuo, we have plenty of time for this project now. The time limit of two months is less than half a month, and we have completed one third of the progress. You don't have to work too hard on yourself. In two days, you'll come back and assign you tasks! "

After that, Cheng Nuo is more anxious.

Indeed, with the current progress, it is a great confidence to complete the project in two months. But the problem is, after a month, he and Professor Fresnel will be away for more than ten days.

Mr. hull is obviously not the kind of assistant who can support a big project by himself.

Therefore, we must speed up the progress of the project. Otherwise, what should we do if Professor Fresnel insists that he should stay in the laboratory at that time?

In any case, Cheng did not want to be absent from the feast of mathematics.

Cheng Nuo's expression suddenly became serious. "Professor, you and Professor hull are struggling in the front line of scientific research. In order to complete the project as soon as possible, you can forget to eat or sleep. As a member of the project team, how can I be alone and leisurely. Please allow me to devote myself to the research of great scientific research

Cheng Nuo has said that. What else can Professor Fresnel do. Cheng Nuo had to be assigned a medium difficulty task first.

Cheng Nuo takes the task and leaves Meizizi.

Fresnel looked at Cheng Nuo humming away from the back, eyes revealed a strong worry.

…………

The intensity of the task has increased a lot, but Cheng Nuo is full of energy.

Under the temptation of the mathematicians' meeting ahead, Cheng Nuo naturally revealed 120% of his energy to the research of the project.

If you can successfully complete the project in one month, you should not be a problem if you want to apply for a 10 day vacation from Professor Fresnel!

Let's talk about the progress of the subject on Riemannian manifolds.

The task of the first stage is basically completed. The basic concepts, the derivation of Fritz John's necessary optimality condition and Lipschitz function, as well as the properties of Lipschitz function have been obtained.

This is the second stage.

As early as when Prof. hull and Fresnel were conquering the first stage, Cheng Nuo had already completed part of the second stage due to his work progress being too advanced. The new task he got today is still the content of the second stage.

In the first stage, according to the content of the generalized Lipschitz manifold, we derive the necessary theorem of the generalized Lipschitz manifold.

This is one of the two core tasks of the second phase.

One of the difficult Professor Fresnel left it to himself, and the first level of difficulty fell to Cheng Nuo.

In the face of this task, Cheng Nuo didn't feel like he had no clue at the beginning of the task, but his mood was not so relaxed.

Because this task, in terms of complexity, is probably more than the sum of the three tasks he has done before.

He needs to be ready for a protracted war.

The first step is to determine the general content of the theorem, and then to deduce the formula step by step.

It took a long time to swish and calculate on the scratchpad before opening a document and typing on the keyboard.

Let the function R: M-R satisfy the local Lipschitz condition near the point work ∈ m, (U, φ) is the coordinate card containing point Z, and the generalized directional derivative of V ∈ LM along the direction V ∈ LM at the point Z is defined as:

F (x, V) = LIM (Y → φ (x)) supF * φ ^ (- 1) (y + T φ x (V)) - f * φ ^ (- 1) (y + T φ x (V)) - f * φ ^ (- 1) (y) t = (f * φ ^ (- 1)) (φ (x); φ * x (V).]

(II) f (x, V) as a function of V satisfies Lipschitz condition

(III) f (x, - V) = - f (x, V)

(IV) 】

[Theorem 3 】

each theorem is followed by a lot of proof steps.

This is a very large workload, Cheng Nuo is not arrogant enough to think that it can be done in one or two days.

Busy day by day, every day in the face of the boring formula characters, Cheng Nuo is not tired.

Ten days later, Cheng Nuo packed the 24 theorems and their proof steps and sent them to Professor Fresnel. Then he asked him for the next stage of work.

Another five days later, Cheng Nuo received a new task, less than half of which was called by Jiang Li to the headquarters of MIT chess and card club.

"I remember tomorrow is the start of the match and I'll be there on time, so you don't have to remind me again and again." Cheng Nuo sat in his chair and said to the current chess and card club Changjiang Li.

"That's not what I'm talking about when I come to you in such a hurry." Jiang Li said with a bitter smile.

"What's that about?"

"I just got the news from the organizing committee that there will be a special player in this go contest!"

"Special player? Who is that? "

"Alpha zero!"

"Robot?! It's cheating

Jiang Li shrugged, "no way. Soon after the alpha zero was developed, although it beat the alpha dog, the people in the research and development group still want to let alpha zero participate in several more competitions with humans to test its performance."

"That doesn't mean that the champion of this competition has been decided." Cheng Nuo ha ha smile, "but it doesn't matter, you let me participate in the competition is not running to the champion, not so sad."

"It's just that I don't know which hapless person it is. I'll run into that robot in the first round."

"Er..." Jiang Li hesitated for a moment, "I have a sad news, do you want to listen to it?"

"Say it." Cheng Nuo road.

"The unfortunate man you are talking about is yourself." Jiang Li opened his mouth and said, "the table has come out. Your opponent in the first round is the robot alpha zero."

Cheng Nuo:

This is really a sad story!
