"You... keep talking!"

Hearing Professor Lin Yao's request, Li Mu didn't talk nonsense, got up and left his seat, and walked to the blackboard.

Picking up the chalk, he began to write.

"First of all, the formula 2.12 we discussed earlier..." Li Mu pointed to the formula 2.12 on the ppt with another finger, "It can actually be equivalently re-expressed as——"

As he spoke, he wrote down new formulas on the blackboard.

[DJ(v)(t)∈S, DJ(v)(t)∈S, ∫ΩDJ(v)(t)...】

Seeing his newly written formula, Lin Yao and Wu Mengyuan also left their seats, and then moved closer together so that they could see more clearly.

Of course, the more important thing is that Li Mu's newly rewritten formula has already caught their eyes.

"And then..."

"Introducing the Lagrangian multiplier λ∈H1 0 (Ω) with the constraint z = 0, it is obvious that problem (3.3) is equivalent to the following saddle point problem..."

...

Time passed by every minute and every second, and the blackboard that occupied one wall was gradually filled with blanks in Li Mu's calculations.

The two professors frowned tightly, apparently lost in thought.

And those graduate students became more and more at a loss.

At first they could understand it, but they couldn't help Li Mu's writing speed, which surpassed their thinking speed in a while, and left them beyond their reach.

Why is this thing actually a Stokes question?

Why is that gqdx = 0?

Why……

They seem to have a thousand reasons at this moment, and even looking at gqdx can automatically be regarded as gdx-a dog thing...

But Li Mu didn't explain at all, he just deduced it there, and probably only the two professors could keep up with his rhythm.

Graduate students want to cry but have no tears, why do they come to this research group!

Why let them meet such a fierce person?

In the end, I swallowed my tears, and honestly took out my mobile phone, and waited for Li Mu to finish writing before taking pictures, and researched when I went back.

In this way, Li Mu finally put down the chalk until the entire blackboard was just finished writing.

Patting the chalk off his hands, he looked up again.

There was no problem in the derivation process, and he basically wrote everything he wanted to write.

The advantages of the brain computer in mathematics are brought into full play in the derivation of this process.

"That's it. I just think that for this kind of nonlinear problem, it should be more effective to calculate the equation in an imprecise but effective way."

"Especially in the CG conjugate gradient algorithm."

While listening to Li Mu's narration, he looked at the full process on the blackboard.

And the writing on the blackboard is so well done, both the font and the overall layout look very comfortable, with a sense of computer precision.

Lin Yao and Wu Mengyuan couldn't help sighing in their hearts at this moment.

What else can they say about such students?

Not to mention that the method given by Li Mu once again solved their problem.

Clean and thorough.

After completely absorbing all the content, Lin Yao couldn't help stretching out his hand, and then clapped his hands.

"Very good, very good."

"This is more than good..."

But Wu Mengyuan shook his head, and couldn't help but sigh with emotion.

The method given by Li Mu is not difficult, and it can even be said that there is no difficult knowledge point in technology, but the victory lies in cleverness.

And if you want to discover this kind of "coincidence", you can only look at your own brain.

Some people may not be able to think of such a "coincidence" after thinking about it for a lifetime.

But for some people, it is extremely easy to come up with such a trick.

Obviously, Li Mu belongs to the latter.

Thinking of this, the two professors couldn't help shaking their heads.

Such a mind is something that even they would envy, but they couldn't envy them.

Lin Yao turned his head and looked at his graduate students, wanting them to learn from their juniors, but saw that the faces of these graduate students still had the look of "Who am I? Where am I?", and finally Shaking his head, he gave up.

Forget it, the grade is not enough.

Although in the eyes of him and Wu Mengyuan, the technical difficulty of Li Mu's method is not high, it is better than cleverness.

But for these graduate students, the technical difficulty is very high, coincidentally...

Where is the coincidence?

I can't even tell.

Finally, Wu Mengyuan patted Li Mu on the shoulder, turned around and said, "That's it, our group meeting today seems to be over early."

"It seems to be the same reason." Lin Yao agreed.

Today's group meeting was originally to discuss this difficulty, but Li Mu stopped the topic before it started.

There may still be difficulties that need to be overcome in the future, but compared to this problem...

It is estimated that it will be simpler.

So there was no nonsense, Lin Yao directly announced the end of this group meeting.

But the graduate students who used to leave every time they finished, stayed and copied Li Mu's writing on the blackboard carefully, and then began to deduce it step by step. is their mentor.

For a while, no one left in this discussion room.

As for Li Mu, he was pulled aside by Wu Mengyuan and asked for warmth.

"How have you learned recently?" Wu Mengyuan asked, but he shook his head after asking, "Forget it, there is probably no need to ask this question."

With Li Mu's current ability, what problems can there be in learning?

So, Wu Mengyuan asked again: "Are there any difficulties in life? If you have any problems, just tell me and I will help you."

Obviously, Li Mu's family is not superior at all, even very ordinary.

This can also be seen from Li Mu's clothes.

If there are still difficulties in life for such an excellent student, won't that affect the display of their talents?

Wu Mengyuan didn't want to see such a thing.

After getting the professor's concern, Li Mu's heart warmed slightly, and he waved his hands and said, "Thank you, Professor Wu, I don't have any difficulties. I just need to eat and learn, and I don't need clothes."

Wu Mengyuan laughed and said, "That's good. If it doesn't work, I'll tell Professor Lin Yao to send you this month's money first."

Li Mu is in their research group and still has a salary of 3,000 yuan a month.

In fact, with Li Mu's current performance, it can't be too high, but there is no way, their research team still has so many people to support.

Li Mu smiled and said, "Don't bother the professor, I'm not so financially stressed right now."

He doesn't have a strong need for money now, so he doesn't need to be so anxious.

"That's good." Wu Mengyuan nodded, and suddenly said: "Oh, by the way, you seem to be going to participate in our physics competition tomorrow, right? I remember that if you can win the first place in the international physics competition, The school will reward 10,000 yuan."

Li Mu's eyes lit up immediately.

To take back what I just said, he needs money very much.

After all, that was ten thousand yuan!

joke!

"I will definitely get this first place!"

Seeing him like this, Wu Mengyuan laughed, "Okay, then I'll wait and present this award to you myself."

Suddenly at this time, a voice came from the side.

"That...Li Xuedi, can I ask you a question?"

Li Mu turned his head and saw a senior graduate student coming to him with a notebook.

What he asked was a question in his derivation process just now.

As for why this postgraduate student took the initiative to ask Li Mu questions...

Taking a look at Professor Lin Yao's place, he was already surrounded by several people. He probably didn't want to wait too long, so he came to look for Li Mu.

Wu Mengyuan on the side nodded approvingly at the graduate student. It is very commendable to be able to ask questions without shame.

Of course, Li Mu did not refuse, and began to explain to the senior.

"We can reformulate this as a linear variational problem with a Lagrangian multiplier λ..."

Li Mu's explanation began, and Wu Mengyuan who was beside him watched, feeling more and more relieved, and at the same time made a decision in his heart.

He wants to provide Li Mu with a perfect college career.

Because it's worth it.
