Just turned over a new leaf and became a wise and intelligent student

Chapter 324: Chinese R&D must use Pinyin
On the top floor of Longjiang Riverside Villa, it was so quiet that only the sound of keyboards could be heard, and no one was discussing any topic.

Xu Qingshan, Jiang Huanxi and Tong Tong, the three of them were clearly in the same room, but they seemed to be immersed in their own little world, each busy with their own things.

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

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

Tong Tong was reading a paper that won the first prize in the ACM Modeling Competition two years ago, carefully studying the wording and sentence structure, especially the tricks used in some logical narrative parts and some solution explanation parts, while secretly glancing at Xu Qingshan.

pity.

Although he was actually quite confident in his mathematical ability, when he really compared it with Jiang Huanxi's, Tong Tong really felt the obvious gap.

You have to know that Jiang Huanxi only went to college for half a year longer, but he has already been left far behind.

This is also why Tong Tong and Jiang Huanxi were still communicating in 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 little, and as a result, they talked less and less.

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

Jiang Huanxi has already reached this level, no wonder Brother Qingshan is willing to let them perform on their own. With Jiang Huanxi's level, even if Brother Qingshan doesn't help, he can just find a classmate from the Computer Science Department and they should be able to get a good ranking in this Mathematical Modeling Competition, right?

Tong Tong couldn't help but look at Jiang Huanxi again who was concentrating, and the formulas in the computer in front of her that he had no idea about.

Do you seem to be lagging behind in some aspects?
If it were an ordinary person, he might be depressed.

But Tong Tong is different.

How could a mere difficulty stop Tong Tong's determination?

Thinking of this, she borrowed Xu Qingshan's authority more seriously and used IP remote access to search for better papers and authors in the library resource library of Peking University to study their style and ideas.

In addition, she also consciously looked for papers in the fields that interested her, taking this opportunity to complete the input of diverse knowledge and slowly screen her future study direction.

She doesn't really just want to study math 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 I develop in, there will always be opportunities to do something for him.

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

If you don't even like what you want to strive for, how much can you achieve?

It's impossible when you think about it.

Identify your own strengths and interests, adopt a differentiation strategy, and become the indispensable person.

hum.

Tong Tong thought about it and felt that his idea was very good and the future prospects were very bright, so he became more motivated to read the paper.

Jiang Huanxi had no idea that the girl next to her had so much inner drama. She was just concentrating on completing the task at hand.

Xu Qingshan had mentioned this when he was giving them special lessons a few 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 include predicting market demand, stock prices, etc., and simulation problems include simulating disease transmission and traffic flow.

If you want to determine what method to use to solve the problem at hand, you need to have a detailed understanding and complete ideas about the question itself.

If it were an ordinary person, he might be at a loss when seeing the question and could only try each method one by one. But Jiang Huanxi is different, she has an external plug-in.

Even though the training time Xu Qingshan gave her was very short, it brought about earth-shaking changes.

"It just so happened that someone mentioned the other day that we could try to think about the problem with reverse thinking. If I were the murderer, based on the murderer's psychology, how should I optimize my route of committing the crime?"

Jiang Huanxi muttered to himself.

Fortunately, this happened at home. If it was outside, it would be easy for her to be misunderstood because of her few words.

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

Jiang Huanxi thinks quickly.

Staying with Xu Qingshan for a long time has made her behavior somewhat similar to Xu Qingshan's.

After all, the influence between people is subtle.

Just like when a couple lives together for a long time, they start to look like each other.

"To complete a multi-level geographic profiling model, I need to consider multiple situations. This optimization solution is an alternative solution for important scenario selection. Question A is a traditional optimization reminder at first glance, and Question B is at most just a means and tool."

Jiang Huanxi's white fingers were dancing on the keyboard, but she was constantly thinking and iterating her ideas, and she was writing and deleting things, but fortunately this did not affect her progress.

"If I can use Bayesian statistical methods to establish a clear connection between the assumptions about criminal behavior and the factors that make up the model, then I can put in a rigorous line of reasoning with sufficient accuracy and operability to complete the weighting of the influence of regional characteristics and crime points, and create a regional geographic profile."

Jiang Huanxi recorded his first thought truthfully.

"In terms of specific operations, we should take the average distance between the crime location and the anchor point, combine the geographic feature G, the attenuation function D and the normalization factor n, and use the probability density calculation method to obtain the crime geographic profile. However, this seems too idealistic. We also need to consider the actual geographical factors, right?"

Jiang Huanxi felt that his idea was feasible, but he continued to organize the rest of his ideas, just like listing out the outline and key points when writing, so that the efficiency would be much higher when executing it later.

There will be no situation where you forget your train of thought while doing something.

Especially in a competition like this where there is almost no rest time, it is impossible to think about problems in the best condition all the time.

Tong Tong is making progress and Jiang Huanxi has achieved some results.

And Xu Qingshan was absolutely focused.

He enjoyed and relaxed this situation where there were only three of them.

People's working state has inertia.

When people adapt to the working environment, they will enter a comfort zone. Some people will become lazy and relaxed in their comfort zone and will have no motivation to work, while some people will become omnipotent and full of confidence in their comfort zone.

Xu Qingshan is obviously the latter.

He could not feel Tong Tong's gaze at all, nor could he hear Jiang Huanxi's whispers.

To him, he was now like an absolute creator.

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

There is no better feeling than being able to control the world.

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

Xu Qingshan also felt the charm of applied science.

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

Applied science is like when Nuwa created human beings, she was constantly tweaking the details bit by bit, adjusting her creation to the ideal state.

Regardless of whether the result of the adjustment is good or bad, the process of huge changes caused by one's own thoughts is simply too amazing.

"If it is only used to predict the molecular luminescence efficiency and calculate the high-efficiency luminescence spectrum, then its functionality is a bit too limited. Besides, these miscellaneous data should be able to be used in other parts. Let's see."

"Let's add the photovoltaic device simulator and hotspot conversion efficiency." Xu Qingshan kept adjusting his ideas.

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

Since we are all doing this kind of thing.

There is no point in producing a half-finished product. The more perfect and complete it can be, the better it should be done.

Moreover, Xu Qingshan prefers to make complex products rather than single-field products.

He simply referred to the more mature scientific computing software on the market, but whether it was electronic structure, quantum dynamics, or classical dynamics, the more mature scientific computing software was basically developed abroad.

This will involve some gaps in experimental processes and data.

The more Xu Qingshan referred to it, the more uncomfortable he felt.

"Let's optimize the various basic functions, integrate them, and iterate according to the versions to make a complete calculation route."

In order to make himself feel more comfortable, Xu Qingshan didn't mind increasing his workload. For a moment, he even forgot about the modeling competition.

The three young men just stayed on the top floor and rarely went downstairs. Even their meals were cooked by Lin Yuehua and brought up to them.

During this time, Lin Qingying came over to take a look.

On the one hand, she was impressed by her daughter's hard work and her concentration and determination which were completely different from her usual life. On the other hand, she was worried whether these children would hurt their health by working so hard.

Fortunately, this period of time did not last too long.

Xu Qingshan didn't have any chance to take action at all. Jiang Huanxi and Tong Tong solved the AMC modeling problem together. It was only during the process of program monetization that Jiang Huanxi asked Xu Qingshan to solve it.

He also basically completed the first complete version of the software.

The foundation had already been prepared in Liangxi before, and the improvements made in recent times have made the software more complete.

However, at present, the completeness of software processes and functions does not represent the accuracy of data and the reliability of various data analyses.

Although Xu Qingshan has built-in visualization modules in the software, these cannot be well tested if the data are not guaranteed to be accurate and precise.

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

Moreover, this kind of work is obviously more of a complicated workload with repetitive content, which is obviously not something Xu Qingshan would do.

Without the slightest hesitation.

Xu Qingshan contacted Qu Jinmou directly.

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

Qu Jinmou was very surprised that Xu Qingshan would call him. When he picked up the phone, the surprise in his words could be seen through the speaker.

"Professor Qu, Happy New Year."

Of course Xu Qingshan wouldn't be so low in EQ as to bring up things right away, he still had the proper etiquette.

Lao Qu is as enthusiastic as ever whether online or offline.

After a long greeting, Lao Qu couldn't stop talking.

"Ahem, it's pretty good. OK, then after the New Year, I'll go to Huaqing to have dinner with you, Old Qu. Don't complain about me eating too much then."

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

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

"Old Qu, well, the workstation is easy to talk about, but I have something I need help with in your lab."

Xu Qingshan said.

"Ah, you have something important to say? Of course, no problem, just go ahead and tell me. Oh, I'm so happy to say that..."

"It's okay, Lao Qu, this is what happened. Wasn't I working on that software in Liangxi last time?"

"Yes, I remember that at that time, every student in our laboratory collected and prepared data for you. So, is there anything that requires us to do more experiments to test the realism or robustness?"

Qu Jinmou said.

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

“Then there’s no need to do an experiment.”

Xu Qingshan approved of Qu Jinmou's attitude. He agreed without hesitation, which was really different from others.

If anything goes wrong in the experiment, Qu Jinmou himself will be responsible.

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

On the other hand, the definition of helping others do experiments is too ambiguous.

"I will package the software for you later. You can distribute it to the more reliable young people in your laboratory. When school starts, ask them to help test the accuracy and reliability with the previous data to see if the software is OK."

Xu Qingshan made his needs clear.

"You've got it done so quickly? What are you going to call it?"

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

"Well, whatever, let's call QSKS."

"QSKS?"

Qu Jinmu thought about it, but couldn't figure out what these four letters stood for?
"Qingshan Branch counts, it's so easy to remember."

Xu Qingshan said casually.

"Ah? Are these the initials of Pinyin?"

"Yes! Since we developed it in China, of course we have to use pinyin. It's OK as long as we can understand it."

Xu Qingshan didn't care at all, as casually as if he had just folded a little frog out of white paper.

“It seems to make sense”

Qu Jinmou felt a little strange for a moment, but he didn't reject it and even felt a little inexplicably refreshed.

This feeling.

It’s like being in the chasing stage all the time, and suddenly having the capital to look down on others and set the rules according to one’s own wishes.

There is quite a bit of arrogance from the strong and the superior.

"That's nothing. If our generation works hard, maybe the standard language for science textbooks will be Chinese characters in the future."

"Let those foreigners figure out our written grammar."

Xu Qingshan's words were full of confidence.
