Scholar’s Advanced Technological System

Although Lu Zhou does not understand economics, in the place of Princeton, any subject that has a relationship with research and mathematics will more or less have some relationship with those who study mathematics.

Especially the kind of economics.

Either a new social production relationship or the scope of human civilization is further expanded. Otherwise, it is difficult to create novel theories through traditional theoretical research methods.

Therefore, to make outstanding research results, mathematics can be said to be the only way out for modern economists. Although this situation has been criticized by traditional economists as a way to show off digital games, it does help the industry solve the problem of numerous doctoral graduates and employment.

In fact, in the field of theory, it has grown so wildly for so many years. Mathematics is a bottomless mine for any computing science. Can you dig out valuable things from it, and see how scholars in other fields can use it? And improve the mathematical tools that have been hammered out from countless puzzles and incorporate them into their own subject areas.

Therefore, although Lu Zhou is not particularly interested in economics, whenever he appears in the coffee shop on the first floor of the Princeton Institute of Advanced Studies at 3 pm, occasionally a professor of economics studies will take the initiative to talk with him. Discuss with him about some mathematical problems that are not so difficult.

After staying in Princeton for a few years, Lu Zhou had dealt with the economics of the big cow, and both hands were counted.

Not to mention those who have won the Nobel Prize, even the editors of "Nature" and "Science" magazines have a lot to do with him.

Anyone with a normal IQ will not risk the offense of such a big man, and will get a master's diploma and degree certificate...

As for why Lu Zhou must be the author of this communication...

It wasn't that he was a co-author of a paper in a district, and he simply didn't want the little tutor to take advantage of him.

Although I still have some concerns, I can see that the omnipotent brother has said this. Xiaoyan will no longer insist on it. After asking about the situation of his parents and his recent good, he will be hungry. Under the urging, reluctantly hung up the phone.

After the laptop was closed, he stretched out the lurking Lu Zhou, took out his mobile phone and took out a takeaway, and then opened the unfinished paper of Xiao Xiao, and looked at it line by line.

"Let me know... seems to be a bit interesting?"

Although he is not very familiar with the Bewley model, the part related to mathematics is no different from the mathematics homework of the primary school students.

After all, no matter how complex the model is, it is impossible to be more complicated and chaotic than the system of plasma turbulence. Even the world-class problems of the NS equation and the model of plasma turbulence can be solved. A Bewley model in the district does not even qualify him for shoes.

For the understanding of functional analysis, if he believes himself second, then no one can call the first.

However, occasionally thinking about some simple questions is also helpful for his research.

Anyway, the takeaway has not been sent, idle is also idle, the right to relax is good.

Hold the ballpoint pen in the right hand, put the left hand on the keyboard, and quickly pass the information in the attachment. The nib of the fingertip at the tip of the boat is like a flying wheel. It runs through a series of smooth and neat traces from the paper.

"Although it's a bit simple, it's really a very interesting math problem... Who used to talk to me when I was in Princeton? It's a bit unclear."

"...Why do you use the Lagrange multiplier method to solve each step in the optimization process?" When calculating a block, the tip of the pen in the Zhou Zhou book paused for a few seconds.

However, it is only a few seconds.

"It is entirely possible to use the endogenous grid method..." He said to himself, Lu Zhou crossed out the previous step and re-written a line of calculations.

"The endogenous grid method is also a bit of a hassle. Optimizing the original mathematical model directly can save at least 20% of the tedious calculations... or 25%."

This kind of problem is really not even a problem.

The gushing inspiration instantly rushed to the wall that was in front of the finish line.

After writing the last line of calculations, Lu Zhou leaned back on the office chair, slightly lowering the screen of the notebook, and letting the front camera aim at a few pieces of scratch paper.

"Little Ai, help me sort out."

"By the way, refer to the Bewley model and compile a new algorithm for my new model."

Xiao Ai: [Received~ handed over to Xiaoai! (▽?)]

Almost as fast as the page turning, the Xiaoai, which completed the calculation step scanning in the shortest time, quickly sorted out the entire mathematical model and marked the possible problems or typos. In front of Lu Zhou.

Lu Zhou simply glanced at it and confirmed that there was no problem in the marked area, and then turned to the computer.

Soon the data was uploaded to a quantum computer located in the underground of the Jinling Institute of Advanced Studies. Almost a few seconds after the completion of the data transmission, the feedback data was transmitted from the quantum computer.

Xiao Ai: [The algorithm is compiled! ()

Xiao Ai: [Through the comparison of 12777 random parameters, the numerical results of the improved mathematical model are basically consistent with the original model, the dispersion is reduced by 13%, and the computational efficiency is improved by 21%. ?(^?^*)]

The dispersion of the calculation results means that he is not very clear, but the efficiency gain of 21% is basically in line with his expected results.

If you use a quantum computer to check a master's thesis, will there be a feeling of taking a cannon to fight a fly?

Forget it, no matter what.

Who wants him to have only one sister?

What's more, the electricity bill in the province is not worth the money...

Thinking of this, Lu Zhou looked at the computer and continued to order.

"Help me edit an email and package the algorithm and the mathematical model together."

Xiao Ai: [Good master! ()

Seeing the text behind the string of bubbles, Lu Zhou suddenly remembered something, and then said, "Right, remember not to stuff your face text and expression packs in the mail, and send the mail normally."

Xiao Ai: [Σ(っ°Д°;)っ]

Lu Zhou: "...?"

Although I don't quite understand what Xiaoai's expression is meant to express, Lu Zhou does not want to destroy the image of his tall, handsome and smart brother in his sister's mind because of a few words or off-line expression packs.

The mail has been sent for almost five minutes.

His mailbox received a reply from Xiaoyan.

Although the content of the email is very short, it is as short as three characters...

[? ? ? 】

Seeing these three question marks, Lu Zhou mouth evoked a smug smile.

I want to come, Xiao Yan is not expected, he only spent an hour, to solve such "difficult" problems.

"Speaking of it, it’s been an hour. How can I order the takeaway?"

After taking a nap, Lu Zhou took out his mobile phone and was preparing to call the food delivery staff, only to find that his takeaway had been signed twenty minutes ago.

Lying in the trough?

Who brought my takeaway?

I was so invested when I solved the problem, so that he did not notice the reminder of the mobile phone.

Just as Lu Zhou was in a hurry, the door of the office rang three knocks, and then Wang Peng, who was carrying the packing box, came in.

"Your simmered chicken rice," put the plastic bag with the packing box on the table. Wang Peng sighed and said, "Let's make a discussion? You want to eat, I will buy it for you, can we not do it later?" Takeaway, this is purely to increase the difficulty of our work."

“It’s easy to get things done when people are hungry,” he reached out and took out the packing box from the plastic bag. Lu Zhou smiled embarrassedly and said, “...said, how come you sent it.”

Wang Peng: "I will be safer to send."

Lu Zhou: "What does this mean, my safety level has increased?"

Wang Peng hesitated and nodded.

"Ok."

There is nothing to hide in this kind of thing.

Just as the controllable fusion research entered a critical stage, the local military region directly transferred a company, responsible for the security work of his place of residence, until the Pangu fusion reactor was connected to the grid to adjust to normal levels.

Although it is not as exaggerated as the original controllable fusion research, the international form is not as severe as it was at the beginning, but the carbon-based chip is, after all, related to the future of the domestic semiconductor industry. Be careful not to be careful.

Hearing this "hmm", Lu Zhou’s hand to open the chopsticks suddenly stopped, and looked at Wang Peng silently.

Just when Wang Peng was a bit incomprehensible by this look, Lu Zhou coughed and said.

"...you didn't do that...try something like a bite?"

Although it’s not clean, or maybe it’s a bit clean...

Unless it is a meal at the dinner table, it is not the case that the food that others have touched is psychologically or physiologically.

"How is it possible?!" was smashed by the words of Lu Zhou. Wang Peng coughed twice and then slowed down. "What time is it? How can you test the poison? But you don't have to worry about hygiene. Dr. Yan has done a simple test, and there is definitely no problem in health."

Lu Zhou: "..."

MMP!

It turned out that I took a takeaway and went to do a test. I said how to send it so slowly!

It made him almost a backhand and a bad review passed.

Only when I heard Wang Peng’s explanation, Lu Zhou was even more entangled.

Before I sent it, I actually passed Dr. Yan’s hand...

This guy has a criminal record...

Lu Zhou still remembers that the goods stole their own cola a year ago.

No, it should be said that Ming Qiang used to drink.

At the thought of this, watching the take-away Lu Zhou, can not help but fall into meditation.

Eat or not eat?

It’s really tangled...
