It wasn't until half an hour later that Yun Rongsheng's heart was a little balanced.

Forget it, this kind of person belongs to the kind of person who destroys the average.

You shouldn't compare yourself to him.

She exclaimed from the bottom of her heart: "That's amazing! What are the SCI districts? ”

"Well, it's from District 1."

"Or District 1?"

Yun Rongsheng's face was even more surprised.

"That should be hard, right?"

Li Mu touched his nose, is it difficult?

"I don't know, anyway, after I finished writing it, I showed it to our professor, and the professor asked me to translate it into English and send it to this journal, which doesn't seem to be ......."

Hard?

The last two words Li Mu thought about it but still didn't say it, well, it's better to be a little restrained.

It's just that Yun Rongshang pursed his lips, although Li Mu didn't say it, but the clear-eyed person knew which two words were to be said later when he heard it.

Who are these people?

Stand.

"Forget it, I won't tell you."

She, who has always been in the top three in her grade point average, doesn't want to talk to this kind of person at this time.

When IQ is crushed, it is the easiest time for people to feel like waste.

"Then I won't bother you, anyway, thank you."

She said, and then took out her phone again, "By the way, let's add a friend, and I'll ask you if I have any questions in the future." ”

Li Mu thought about it in his heart, and finally took out his mobile phone to add friends, and then remarked a big zero senior sister.

As for what he had in mind?

Well, with the difficulty of Yun Rongshang's question, he usually can't delay him for a minute.

It won't affect his studies.

If Yun Rongshang knew that this was the kind of question he was thinking about before adding friends, I am afraid that his fists would be hard.

Finally, Yun Rongshang left, and Li Mu shifted his gaze to the computer screen.

Well, I didn't have any expectations, but I might as well refresh it.

pressed F5, and as the page refreshed, Li Mu was stunned.

I saw that the status of the paper had changed.

【Manuscript received by Editorial Office】

This means that the manuscript has already reached the review editor.

Even if the submission is successful.

How long has it been?

Didn't you say on the Internet that this process usually takes a long time?

Li Mu thought of the assistance that the system said just now, could this be what it meant?

It's not clear how this is done, but this ability to directly affect reality......

He felt even more uncertain about the origin of the computer and system in his mind, especially when he thought of the real cosmic environment simulation function of the computer in his mind and the function of extracting the underlying running programs of the universe.

Finally, he shook his head.

Forget it, I still don't want to, I'm afraid the doorway in this is not something he can figure out now.

It's better to take care of what you should be doing at the moment.

As for what he should be doing now, he naturally continued to study.

Because he participated in the research group of the two professors, and according to the recommendations of the two professors, he already knew the list of books and papers he was going to read next.

So, let's start looking at it now.

No more nonsense, start with the book.

Then he entered the library, found a few books recommended by Professor Lin and Professor Wu, and then began to read.

……

The days went by.

For learning, with the passage of each day, what has been accumulated is a deeper and deeper heritage.

Li Mu gradually felt his own fulfillment.

In addition, he basically participates in the discussions between Professor Lin and Professor Wu every day or two.

At first, he still only asked questions, but after a few days of study, he was gradually able to put forward his own ideas and suggestions, and contribute to the progress of their projects.

This made Lin Yao and Wu Mengyuan feel very surprised.

To be honest, they invited Li Mu to participate in their research group, in fact, it was more to let Li Mu increase his knowledge and cultivate his experience in doing projects, but they really didn't think about what Li Mu could bring to them.

However, Li Mu's performance after coming in completely exceeded their expectations.

Until another group meeting two weeks later.

"Now we need to be very clear that CG algorithms are very difficult to implement numerically."

Lin Yao sat in his seat, facing the students present, and stated his opinion.

Perhaps thinking of the test, he turned his head to look at the students present.

"Can any of you say why?"

In addition to him and Professor Wu being the main leaders of this project, there are naturally graduate students who work in the research group.

So there are five graduate students, three doctoral students, and two master's students in the conference room.

As for Li Mu, he is the youngest in the audience and the least educated.

An ordinary-looking undergraduate freshman student.

After hearing Lin Yao's question, the graduate students present all showed a deep contemplation.

But Li Mu is completely gone.

He opened his mouth, then looked at the seniors next to him, and finally forgot it.

Give this opportunity to the seniors.

It's not that hard anyway.

It's just that Lin Yao probably saw his movements, so he said with a smile: "Li Mu, you can say it if you want to, you seniors don't have to save face." ”

"Uh......"

Li Mu scratched his head, since the professor said it, then he said it.

"There are two main difficulties, first, although the equation of state is linear, state y is nonlinearly dependent on control v. Second, a non-divergence constraint is added to control v, i.e., ∇·v = 0, which is coupled to the equation of state (1.2). ”

"Well, to be more precise, state y is a nonlinear function that controls v, which leads to the problem we study also becoming a nonlinear problem, and the nonlinear problem is often the difficulty of this kind of problem."

Hearing Li Mu's story, Lin Yao smiled: "That's good, that's right, the key problem lies in this nonlinearity." ”

"Okay, so let's think about how we need to solve this problem."

"We can't take the usual line search strategy, where we have to evaluate the objective function value repeatedly every time, and each evaluation requires solving the equation of state, which is too expensive to calculate and has been reflected in many other people's papers, so we need to find a new strategy."

Wu Mengyuan next to him also nodded: "Well, I think this question is the most difficult part of our subject, think about it." ”

With that, the two professors were ready to discuss together.

The graduate students exhaled.

Professor Lin suddenly asked a question just now, which startled them, because Lin Yao just likes to test them at the group meeting, and if no one answers, he will call them by name.

It's just that what they didn't expect was that they hadn't even started to think about it, Professor Lin Yao directly named the undergraduate, and what he didn't expect was that the undergraduate student actually said it directly.

They all glanced at Li Mu a few times, and then whispered together.

"By the way, do any of you know where he came from?"

"I don't know, I just know it's a freshman."

"Damn, why is he so awesome!"

But there's still more to come.

After a moment of thinking, Li Mu suddenly spoke again: "I seem to have a little idea. ”

"By introducing an additional linear parabolic problem, a non-exact but efficient step strategy can be implemented, and most importantly, it is computationally cheap!"

"It's easy to solve our current problem."

Hearing his words, Lin Yao suddenly sat up straight, with surprise and disbelief on his face.

"You...... Keep talking! ”
