Xiao Yi smiled and said, "After I finish this, I will probably have to run it on your old antique server to do some small-scale calculations."
Luo Mingya was helpless and said, "Okay, then I will have to reluctantly use that server later."
"She seemed to have said just now that dogs are not needed." Liu Chao whispered to Xu Ming next to him.
Unfortunately, Luo Mingya heard it. She looked over quietly and said, "Well, Junior Brother Liu, you and Xu Ming will be responsible for the garbage and sanitation in the laboratory this month."
"Huh?"
Liu Chao's eyes suddenly widened.
Then he slapped himself on the mouth, "Why can't I control this mouth?"
Xu Ming laughed loudly and patted his shoulder, "Good brothers! We share blessings and share hardships!"
Soon, Xiao Yi optimized their algorithm. Without saying much, they returned to the computer room to conduct a small-scale simulation of this new algorithm.
Because it was just a small-scale simulation that didn't take long to run, they got the results quickly.
After the optimization of Xiao Yi, the utilization efficiency of computing resources has increased by almost 20%, and both the convergence speed and calculation accuracy have been improved.
Although this does not directly help them obtain research results, it can greatly speed up the research process and save a lot of research time. From this point of view alone, it is very rare.
"Awesome! Scholar Xiao."
Seeing this result, Xu Ming immediately opened his eyes wide and exclaimed.
Others also expressed surprise.
Luo Mingya said, "Thank you, Junior Brother Xiao."
Xiao Yi smiled and waved his hand, "It's okay. After all, I am also a member of the research team now. Optimizing algorithms and other things are also my responsibility."
"Sun Lina, look at how humble Scholar Xiao is, where are you? It's time to play again!"
Luo Mingya turned around and attacked Sun Lina. At this time, Sun Lina had already picked up the switch and started playing.
"Don't cue, don't cue." Sun Lina waved his hand. "The world belongs to you young people. Let you young people do this kind of thing."
However, Luo Mingya silently took out his mobile phone at this time and started playing a recording.
"Who is not an 18-year-old pure and lovely girl~"
"Ahhhh!!!"
Sun Lina jumped up immediately. "Luo! Ming! Ya! I will fight with you!!"
Then she rushed up and tried to snatch Luo Mingya's mobile phone.
Xiao Yi They looked at this scene in stunned silence.
The voice in Luo Mingya's phone just now... seems to be the voice of Teacher Sun, right?
"It's over, we won't be killed and silenced by Teacher Sun, right?"
Liu Chao hugged his head with a look of horror on his face.
The farce ended quickly, and their discussion for the day ended here.
The laboratory still needs to work next. After all, they not only have one subject, but also many other subjects.
According to what Xiao Yi heard from Xu Ming and the others, Luo Mingya, as the actual controller of this laboratory, has at least three projects in progress at the same time.
Their project is considered a relatively important one at present. If it succeeds, there will be a chance to evaluate State Natural Science Award.
As for the junior students like them, if they have a slightly better topic, Luo Mingya will also provide them with some help, whether it is funding or guidance.
All in all, their senior sister is actually a senior sister who is very good to them. Probably the only problem is that she cannot tolerate any sand in her eyes. If she is lazy, she will definitely criticize her.
So, as soon as this discussion ended, they returned to the laboratory and continued their tasks.
As for Xiao Yi, he was naturally fine. After understanding the topic, he also looked at the mathematical model that had been established so far.
The next task is only to study.
And this is something you can learn.
First of all, he must start from some basics. He must understand at least the prerequisite knowledge about Computational Materials Science, especially the related content about Density Functional Theory and first principles calculation.
After all, he had to understand the principles of that mathematical model first.
Fortunately, Luo Mingya not only recommended the textbooks he needed to read, but also lent him the books she had read before. After all, the library has not officially opened yet, so borrowing books will definitely not be available. If you want to buy books, it may take a few days to arrive.
As a similar genius, Luo Mingya knows very well that if he loses so many days of study time, he doesn't know how much knowledge Xiao Yi will learn.
The earlier Xiao Yi understands the principles of computational materials methods such as Density Functional Theory and first-principles calculations, the sooner we can provide them with more help.
In this way, time passed quietly.
Library study room.
Although the library is not open, the study room is already accessible.
Of course, because the school has not officially started yet, the study room is empty. Those who can study here now are either those who did not go home during the Chinese New Year, or those who came back to open books before the vacation was over.
The entry of Xiao Yi did not attract the attention of others. He carried his schoolbag, found a corner, and opened "Density Functional Theory: A Practical Introduction" in his hand, a classic book by Density Functional Theory. The English name of Density Functional Theory is Density Functional Theory, and the abbreviation is DFT.
According to the traces on this book, it can be seen that Luo Mingya has turned over every page of this book many times.
However, from the appearance point of view, the book is still neat and tidy despite being turned over many times.
After turning the first page, he officially entered into learning.
Density Functional Theory is the cornerstone of Computational Materials Science. It was the birth of this theory that officially introduced the research of Materials Science to computers.
DFT uses electron density to describe the ground state properties of multi-electron systems, avoiding the difficulties caused by directly solving the complex multi-body Schrödinger equation.
Of course, as a top mathematician, after reading it a few times, Xiao Yi easily started to think about how to connect the variation principle in mathematics with the strict expression in DFT.
In addition to the content in the book, it also includes notes written by Luo Mingya.
He glanced at two lines of notes: [The Kohn-Sham equation simplifies multi-electron problems into single-electron problems, but the choice of exchange-correlation energy functional is crucial.]
[The applicable scopes of LDA and GGA are different, but how to balance accuracy and computational cost in actual calculations is a problem that requires in-depth study.]
Xiao Yi nodded slightly, these notes hit the point.
In general, various theories of Computational Materials Science have a balance problem between calculation accuracy and calculation cost. For example, first-principles calculation has relatively better calculation accuracy, but at the same time, its requirements for calculation cost are very high. This is a problem for any research group. After all, whether it is funds or time, everyone is limited.
On Earth Online, no one can open a cracked version.
Time passed slowly, and the book also gave an example question about the electronic structure of silicon crystals.
He thought over and over again and thought about the examples from many aspects.
The more he thought about it, the more he was able to appreciate the impact of different functionals on calculation results.
As a mathematician, and a mathematician with outstanding talents, he couldn't help but start thinking about whether he could improve the construction of functionals through mathematical optimization methods.
"The basic idea of Density Functional Theory is to express the energy of a multi-electron system as a functional of electron density. The Kohn-Sham equation simplifies the electronic system into the movement of a group of non-interacting electrons in an effective potential field, which effectively reduces the computational complexity."
"Obviously, the solution to the Kohn-Sham equation depends more on the precise form of the exchange-correlation energy functional. If it can..."
Xiao Yi's thinking became more and more in-depth.
From Density Functional Theory, to first principles, in addition, Computational Materials Science also includes a variety of other methods, such as Molecular Dynamics and Monte Carlo Simulation and so on.
Of course, he did not forget to study other basic theories, including Materials Science basics, Quantum Mechanics and so on.
In this way, a few days passed quietly.
A few days later.
In the Entrepreneurship Center.
"Master, what do you do?"
Liu Chao looked at the masters who were moving servers in front of him and suddenly asked.
There was silence for a moment, and everyone present looked at him.
Liu Chao suddenly came to his senses, then coughed awkwardly and said, "Um... I'm going to the toilet."
"I'll go with him."
Xu Ming, who was a little unable to hold himself up, ran over and then heard a burst of hearty ridicule from the other side of the corridor.
Xiao Yi suppressed his laughter and continued to watch from the side.
This is a server cluster he bought with a huge investment of 5 million, and Xu Ming provided a lot of suggestions.
After entering the venue, the masters began to assemble these servers.
Hmm... 5 million should be enough for a while, right?
Xiao Yi began to think in his heart.
At this moment, his cell phone rang, and it turned out to be a call from Boss Huang.
"Haha, Xiao Yi, all the 1.5 million royalties from me have been paid to you."
Hearing what the other party said, Xiao Yi smiled and said, "Okay."
Yes, although 5 million was spent, 1.5 million was recovered, which is not bad.
This usage fee is the activation fee for each mining machine using Yishui Bit.
After using it for free in the past few days, Boss Huang has naturally seen how awesome this software is, so as soon as the free trial period was over, he paid all the usage fees for almost 30,000 mining machines in his mine.
1.5 million may seem like a lot, but in fact it's not much at all.
According to the current price of Bitcoin of US$55,000, even if his mine does not use Yishui Bit, its daily revenue is about 3.5 million yuan. Now that he has Yishui Bit, he will go directly to 6 million. It is only 1.5 million, and he can earn it back in one day.
"In addition, Genius Xiao, Yishui Bit, I have helped you promote it. According to what you said before, isn't it going to be open for download today? But I haven't seen you open it yet. Now people from other mines are calling me and asking me what's going on."
"I estimate that at least 200,000 mining machines will use your software this time." Well, you can try
you are not alone
