Chapter 324 Of course, Chinese R&D must use Pinyin

The top floor of Longjiang Binjiang Villa was so quiet that only the sound of the keyboard was left, and no one was discussing any topics.

Xu Qingshan, Jiang Huanxi and Tong Tong are obviously in the same room, but they seem to be immersed in their own little world, each busy with their own things.

Tong Tong is strengthening his English written writing skills, especially scientific research papers.

Although for things like mathematical modeling or scientific research papers, the beauty of the language is not too important. You only need to consider the fluency and accuracy of expression.

While Tong Tong was looking at an essay that won the Grand Prize in Modeling from two years ago, he carefully studied the words and sentences in it, especially the little techniques used in some logical narrative parts and some plan explanation parts. He glanced at Xu Qingshan.

What a pity.

Although he was quite confident in his mathematical abilities, Tong Tong really felt the obvious gap when he really tried it against Jiang Huanxi.

You must know that Jiang Huanxi only went to college for half a year, and he was already far behind.

This is why Tong Tong and Jiang Huanxi communicated at the beginning, but now they are just doing their own tasks, because when Tong Tong was discussing with Jiang Huanxi, he found that the knowledge he possessed was still too much. If there is less, the result is that the more we talk, the less we talk.

Moreover, Tong Tong can't help but think about it.

Jiang Huanxi has already reached this level. No wonder Brother Qingshan is confident to let the two of them perform first. With Jiang Huanxi's level, even if Brother Qingshan doesn't take action, any computer classmate should be able to do it. Did you get a good ranking in this mathematical modeling competition?

Tong Tong couldn't help but look at Jiang Huanxi, who was attentive, and the calculations on the computer in front of her that she had no understanding of at all.

Do you seem to be lagging far behind in some aspects?

If you were an ordinary person, you might be depressed.

But Tong Tong is different.

How could a mere difficulty stop Tong Tong’s heart?

Thinking of this, she borrowed Xu Qingshan's authority more seriously and searched for more excellent papers and authors through IP remote access in Beijing University's library resources to study their style and ideas.

In addition, she also consciously searched for papers in the fields she was interested in. She took advantage of this opportunity to complete the input of diverse knowledge and slowly selected her future study direction.

She doesn’t really just want to learn mathematics like Jiang Huanxi.

Tong Tong has a clearer understanding of himself.

Brother Qingshan’s career field will definitely not be limited to mathematics and computers. No matter which direction he develops, there will always be an opportunity to do something for him.

I am myself first, and then my brother Qingshan’s child.

If you want to strive for something that you don’t even like, how much achievement can you make?

It’s impossible if you think about it.

Determine your own strengths and interests, adopt a differentiated strategy, and become an indispensable person.

Hmph.

When Tong Tong thought about it, he felt that his idea was wonderful and his future prospects were wonderful. He was very motivated to read the paper.

Jiang Huanxi had no idea that the little girl next to him was having so much inner drama. She was just concentrating on completing the work at hand.

Xu Qingshan had already mentioned it when he started a small stove for them two days ago.

The normal types of questions in mathematical modeling competitions are actually optimization problems, prediction problems and simulation problems.

Optimization problems include resource allocation, path planning, etc., while prediction problems involve predicting market demand, stock prices, etc. Simulation problems involve simulating disease spread and traffic flow.

If you want to determine what method to use for the problem at hand, you need to have a detailed understanding of the topic itself and a complete idea.

If you are an ordinary person, you may be blinded when you see the question, and you can only try one method one by one. But Jiang Huanxi is different. She has an external plug-in.

Even if the training time Xu Qingshan gave her was short, it was an earth-shaking change.

"I just mentioned that day that I could try to think about the problem with reverse thinking. If I were the murderer, how should I optimize my murder route based on the murderer's psychology?"

Jiang Huanxi murmured to himself Said.

Fortunately, this is at home. If she were outside, it would be easy for someone to misunderstand her just because of her few words.

“Although the optimization plan does not mean that the murderer’s route can be completely simulated, there are crime anchor points and various activity coordinates, and the basic points of the optimization plan are already there.”

Jiang Huanxi’s Thinking quickly.

Being by Xu Qingshan's side for a long time made her behave somewhat like Xu Qingshan.

After all, the influence between people is subtle.

Just like a couple living together for a long time, they will also look like a couple.

“To complete a multi-level geographical profiling model, I need to consider a variety of situations. This optimization solution is an alternative for important scene selection. Question A is a traditional optimization reminder at first glance. , Question B is only used as a means and tool at most."

Jiang Huanxi's white fingers danced on the keyboard, but she kept thinking, iterating her ideas, and writing and deleting what she wrote. Deleted, fortunately this does not affect her progress.

"If I use Bayesian statistical methods to establish a clear connection between the criminal behavior hypothesis and the factors that make up the model, then I can substitute a rigorous line of reasoning and have enough accuracy and operability to complete various areas. The influence weight of characteristics and crime points is used to create a regional geographical profile.”

Jiang Huanxi recorded his first thoughts truthfully.

“For specific operation, it should be to take the average distance between the crime location and the anchor point, combine the geographical feature G, the attenuation function D and the normalization factor n, and use the probability density calculation method to obtain Crime geography profile But this seems too rational After thinking about it, you still need to consider the actual geographical factors, right?”

Jiang Huanxi felt that his idea was feasible, but he still continued to organize the rest of his ideas, just like listing the outline and key points when writing. , if executed at that time, the efficiency will be much higher.

It won’t happen that you forget your own ideas while doing it.

Especially in this kind of competition where there is almost no rest time, it is impossible to think in the best condition all the time.

Tong Tong is making progress, and Jiang Huanxi is making some achievements.

And Xu Qingshan is absolutely focused.

This state of being with only the three of them made him enjoy and relax.

People's working status will have inertia.

When people adapt to the work environment, they will enter a comfort zone. Some people will become lazy and relaxed in the comfort zone, and will have little motivation to do work, while some people will become omnipotent in their comfort zone. Be confident.

Xu Qingshan is obviously the latter.

He couldn't feel Tong Tong's eyes at all, and couldn't hear Jiang Huanxi's murmur.

For him, he is now like an absolute creator.

He moved his fingers wantonly, gently playing with the mysteries of science, and lifting the skirts of digital characters.

There is no better feeling than having control over a world.

Even if this world is composed of abstract algorithmic rules and concrete strings.

Xu Qingshan also felt the charm of applied science.

If all the scientific research on pure number theory he had done before was more like deciphering the final answer to the universe.

Applied science is like when Nuwa was creating humans, she was constantly tweaking every detail to adjust her creation to an ideal state.

No matter whether the result of the adjustment is good or bad, the process of a huge change just because of one's own thoughts is simply too amazing.

“If you only predict the luminescence efficiency of molecules and calculate high-efficiency luminescence spectra, the functionality would be too limited, and these miscellaneous data should be able to be used in other parts, let’s see.”

"Add photovoltaic device simulator and hot spot conversion efficiency." Xu Qingshan continued to adjust his thoughts.

But this does not mean that he is wrong, but that he wants to add more things to his creation.

Now that everyone is doing this kind of thing.

There is no point in pulling out a half-finished product. The more perfect and complete it can be, then find a way to do it.

And compared to single-field products, Xu Qingshan prefers to make composite products.

He briefly referred to the more mature scientific computing software on the market. However, whether it is electronic structure, quantum dynamics, or classical dynamics, the more mature scientific computing software is basically developed abroad. of.

This will involve some gaps in experimental procedures and data.

The more Xu Qingshan looked at it, the more uncomfortable he felt.

“Let’s optimize various basic functions, integrate them, iterate according to the version, and make a complete calculation route.”

In order to make himself more comfortable, Xu Qingshan does not mind adding His workload was so heavy that for a while, he forgot about the modeling competition.

The three young men just squatted on the top floor and never went down. Even the meals were served to them by Lin Yuehua.

During the period, Lin Qingying came over to take a look.

On the one hand, she lamented her daughter's hard work and her concentration and determination that were completely different from her usual life. On the other hand, she worried about whether these children would be hurt if they worked so hard.

Fortunately, this time did not last long.

Xu Qingshan had no chance to take action. Jiang Huanxi and Tong Tong solved the problem of Mesai modeling. It was only in the process of monetizing the program that Jiang Huanxi asked Xu Qingshan to solve it smoothly.

And he himself basically made the first full version of the software.

The foundation has been laid out in Liangxi before, and the recent improvements have made the software more complete.

However, at present, the software process and functions are complete, which does not mean the accuracy of the data and the reliability of various data analysis.

Although Xu Qingshan has built-in visualization modules in the software, these cannot be well tested without ensuring the accuracy and precision of the data.

But if he wanted to test the reliability of the software, Xu Qingshan's personal workstation at home was enough. But with only one workstation and so much data, he didn't know how long he would have to run it alone.

And this kind of complicated workload is obviously more repetitive work content, which is obviously not what Xu Qingshan will do.

Without any hesitation.

Xu Qingshan contacted Qu Jinmu directly.

He knew that Qiu Yong was busy with more important things now, and it would be more convenient to go to Professor Qu, the general manager of their laboratory, for such matters.

Qu Jinmo was very surprised that Xu Qingshan would call him. When he answered the phone, the surprise in his words could overflow from the speaker.

"Professor Qu, Happy New Year."

Of course Xu Qingshan would not bring up things when his emotional intelligence was low, and he still had the proper etiquette.

Whether online or offline, the old songs are as enthusiastic as ever.

After chatting for a long time, Lao Qu couldn’t stop talking.

"Ahem, it's quite good. Okay, then I'll go to Huaqing to meet Laoqu for dinner after the Chinese New Year. Don't dislike me for eating too much."

Xu Qingshan looked back at Tong Tong, who was stretching in the room, and Jiang Huanxi, who was lying on the sofa looking languid, and wanted to quickly bring the topic back to business.

"How could that be? You believe me, our Huaqing University canteen is much better than Peking University. I will prepare a large workstation for you in our laboratory with the same specifications as mine." "

"Laoqu, what, the work station is easy to find, but I really have something to do here and I have to ask your laboratory for help."

Xu Qingshan said.

"Ah, I have something serious to do. Of course it's no problem. You can just say, oh, I'm just happy to say it"

"It's okay, Laoqu, that's it. Last time I Aren’t you working on that software in Liangxi?”

"Yes, I remember that at that time, every student in our laboratory was collecting and preparing data for you. How about, is there any place where we need to do more experiments to test the fidelity or fidelity? Awesome? ”

Qu Jinmou said.

"There is no problem with doing experiments. The experimental quota can be calculated from my side, but I have to tell Lao Qiu. Can I talk to him?"

"Then there is no need to do experiments. ”

Xu Qingshan recognized Qu Jinmo’s attitude very much. He agreed without saying a word, which is really different from others.

If there is a problem with the experiment, the person responsible will be Qu Jinmou himself.

Moreover, if the experimental consumables and quota exceed the standard, Qu Jinmou will have to pay for it out of his own pocket.

On the other hand, the positioning of helping others conduct experiments is too ambiguous.

“I will package the software for you later, and you will distribute it to the more reliable young people in your laboratory. When school starts, let them help test the accuracy and reliability using the previous data, and take a look at the software. O is not OK.”

Xu Qingshan made his needs clear.

“It’s done so quickly? What are you going to call it?”

Qu Jinmo was even more surprised, but on the other hand, he was secretly glad that he had a firm attitude.

"No, let's call it QSKS."

"QSKS?"

Qu Jinmou thought for a while, but he couldn't figure out what these four letters represent. What?

“Qingshan Branch, it’s so easy to remember.”

Xu Qingshan said casually.

"Huh? Is this the first letter of Pinyin?"

"That's right! What we developed in China must of course use Pinyin, as long as we can understand it."

Xu Qingshan was nonchalant, as casually as if he had folded a little frog out of white paper.

“It seems to make sense”

Qu Jinmou felt a little strange for a while, but he didn't reject it and felt a little inexplicable.

This feeling.

It's like a being who has been in the chasing stage suddenly has the capital to stand out from the crowd and set the rules according to his own wishes.

There is quite a kind of arrogance of the strong and the superior.

“It doesn’t matter. We have worked hard for generations, and maybe the standard text in science textbooks in the future will be Chinese characters.”

"Let those foreigners figure out our writing grammar."

Xu Qingshan's words were full of confidence.
