Genius of the Rules-Style System

Zhang Hongtao couldn't figure out why Zhao Yi was able to accurately import the elements contained in the plates.

‘Neptunium’ is element 93.

There is still very little research on this element at the bottom of the periodic table in China, and some added materials are almost all imported from abroad.

If you were an expert on alloy materials and wanted to tell directly that the plate contained neptunium, you would almost have to rely on guessing, because there are several metal elements that can be added at the back of the periodic table. How do you know it is neptunium?

Zhang Hongtao couldn't understand.

At the same time, he didn't think that Zhao Yu was blinded just now. The look on his face seemed to confirm that it contained neptunium.

That's not a joke.

Zhang Hongtao followed Zhao Yi all the way with doubts. He kept looking for topics to chat with Zhao Yi. The topics were basically related to materials and alloys. He was having exploratory conversations.

Zhao Yi kept nodding along and said little.

Zhang Hongtao seemed to want him to express some opinions, but Zhao Yi didn't understand what he was talking about at all. He knew about metal elements and could memorize some of the periodic table of elements, but what kind of alloys were made and how much temperature a certain metal was heated to have different effects? What effect, what color and characteristics of a certain rare metal, etc.

How is it possible to know this!

What Zhang Hongtao said was very professional, and they were all about metal materials, alloys, etc. Zhao Yi could only listen and nod along, as if he pretended to understand, but in fact he was complaining in his heart, "Everything this guy said is... It’s Chinese, I understand every word, every word, and even the meaning of some sentences, but why don’t I understand the whole thing when put together..."

When Zhao Yi was explaining just now, he said that it was about ‘occasionally looking at’ materials science. He had already said it, so he definitely couldn’t understand everything.

So I will still speak when I can.

For example, some questions with limited answers.

"Could neptunium and aluminum be fused together in a way that would make it more resistant to high temperatures?"

"Can the proportion of carbon element that plays a harmonious role exceed 0.5%?"

“Is it possible to add two rare metal elements to create a material that is more resistant to high temperatures and stronger?”

Zhao Yi’s answer is ‘yes’ and ‘no’.

reason?

He won't explain it carefully.

Anyway, the two of them were talking in the form of a chat. They seemed to be discussing academic issues. In essence, they were just chatting casually. Zhang Hongtao had no way to delve deeper.

After going through this journey, Zhao Yi really didn't want to stay with Zhang Hongtao.

After leaving the metal materials experimental base, he quickly walked next to Liu Guangzuo and found that Liu Guangzuo was actually quite good.

least……

This guy doesn't bother talking about metal stuff.

Just now, in order to talk to Zhang Hongtao and show that he had a certain understanding of materials science, he spent almost 20 points of energy using the "Law of Cause and Effect" to find the answer to the question.

20 points of energy is equivalent to two learning coins, which doesn’t sound like much, but it’s meaningless!

the other side.

Zhang Hongtao stood at the door of the materials laboratory, looking at the group of people leaving, and became even more curious about Zhao Yi.

When he was talking to Zhao Yi just now, he deliberately asked some questions that he knew, and Zhao Yi answered several of them correctly.

It can be said……

As long as it was a question to which he knew the answer, the other person would always answer it correctly.

Presumably, those who don't know the answers to questions may also be right.

Although it was just a tentative conversation, Zhang Hongtao was still very surprised, because Zhao Yi is a mathematician and computer expert who has also made achievements in physics. It is said that he is also a researcher in a biomedical laboratory.

None of this has anything to do with chemistry!

It would be incredible if Zhao Yi also had some research in the field of metal materials.

He is an all-powerful person!

"When I have the opportunity, I should ask, what problems did I encounter in my research?"

"Perhaps...he can give very useful advice?"

Zhang Hongtao thought that he should discuss it more with Zhao Yi in the future.

The other person is a true genius.

Although the basic knowledge in the fields of chemistry and materials may not be solid enough, some of the other party's ideas may be very creative.

What scientific research requires is creativity.

After a large group of people left the materials laboratory, they visited two teaching buildings, including the graduate student laboratory building, and then returned to the computer laboratory building around the same time.

They crowded into the small conference room.

Zhao Yi was placed in the front row. He glanced left and right and found that there were about thirty to forty people in the conference room.

This number is definitely quite large.

Although it cannot keep up with those large-scale studies, you must know that the minimum standard in the conference room is associate professor (associate researcher) or above, and there are two academicians, including Liu Tongen, the designer of the national navigation system, and another one from Capital Aerospace. University computer science fellow.

Zhao Yi was placed in the first row, probably because of his research results. He has the world's top achievements in the fields of mathematics, physics and computers. This is the case in the academic circle. If you have achievements, you will have a corresponding status.

Even if he only attended the meeting as a distinguished researcher (intern researcher) of the Intelligence and Automation Laboratory, he was still placed in the best position, and no one else had any objections.

But Zhao Yi is indeed ‘of no use’.

The content of this meeting has been determined, which is to assign the work of error correction coding in the positioning system.

Capital University of Aeronautics and Astronautics is responsible for designing error correction codes. The Intelligence and Automation Laboratory of Yanhua University is small in scale and has only been assigned a part of the work, which is about a quarter of the overall error correction codes.

The workload is also very stressful.

Error correction coding refers to a code that can detect or correct errors at the receiving end after errors occur during transmission.

This kind of coding has the ability of error detection and correction. It is necessary to add redundant code elements to the original code words to expand the difference between code words, that is, to turn the original code words into code words with a certain degree of remainder according to certain rules. , so that there is a certain relationship between the codes of each codeword.

The above explanation seems a bit complicated. A simple understanding is that after each part of the program in the source code, a part of error correction code will be added to detect errors, deletions and other problems that may occur during the information transmission process.

When the error correction code finds an error, it will automatically correct it.

The reason why error correction coding is important is that character packet loss is likely to occur during information transmission.

For example, a message: 1234567890.

When transmitted to the terminal, it may become 1234560, and the three characters 789 are lost directly.

At this time, the role of error correction coding is reflected. The coding will automatically detect the integrity of information transmission by running the program. If problems are found, they will be corrected and added in a timely manner.

The existence of error correction coding ensures the security and integrity of transmission, and also allows information to be transmitted in multiple ways without fear of too much packet loss in the process.

The above explanation can almost tell how much work is required for error correction coding.

The computer academician from Shouhang is responsible for this piece of work. He has already designed the error correction coding framework. What the meeting needs to do is to allocate work, assign part of the function code to this person, and assign part of the function code to that person...

etc.

After the assigned work is completed, it is time to discuss the sharing of information during the research and development process, because the whole thing is made of one thing, and they require team cooperation. There must be docking between codes and information sharing.

The meeting went very smoothly. The only special thing was Zhao Yi. He almost fell asleep listening to it because the whole content had nothing to do with him.

Liu Tongen invited him over because he wanted him to give opinions, but the overall framework was already done, which meant that the work had been arranged, and there was no way to give opinions on the distribution.

Fortunately, the meeting was still fruitful.

[Extra rest, study coins +2. 】

[Extra rest, study coins +2. 】

[Extra rest, study coins +2. 】

The system prompt was really unexpected.

"So you can get rest coins even if you sleep during a meeting?"

"That's not bad."

Of course.

The sequelae are also huge.

The teacher doesn't care too much about sleeping during class, and no one cares about sleeping during meetings. But looking at the old professors holding back laughter on both sides, Zhao Yi didn't know what expression to show.

"Ahem... I didn't sleep well last night." He explained awkwardly.

"Are you thinking about my brother's guess?" an unknown old guy said with a smile on his face.

"Ahem...yes, yes."

"I've heard that you are studying Ge Guai, is there any progress?" The old guy seemed very proud that his guess was correct.

"A little bit."

Zhao Yi's answer was a bit surprising.

The old guy opened his mouth and asked, "Is there really progress? Can you tell me?"

"That's too much!" Another person next to him jokingly reminded him. The old guy also knew that he was a little too much. He would definitely not disclose information about other people's mathematical research until the results were confirmed.

He was just too surprised.

Zhao Yi shook his head and said, "I just determined which method to use, and the real results haven't been achieved yet."

"So that's it."

Several people around him nodded.

This is right!

That is Goldbach's conjecture. It has been almost half a century and there has been no progress. Even if Zhao Yi is a genius in number theory, it is impossible to produce results in such a short time.

A few people only said a few words jokingly.

The meeting is over.

Most people were discussing the content of the research work, which had nothing to do with Zhao Yi. He looked around and thought about whether he should go back first and let Liu Guangzuo continue to communicate here. Unexpectedly, Liu Tongen found him. .

Liu Tongen sat next to him, and he knew something was wrong from the look on his face.

Zhao Yi wanted to leave quickly, but unfortunately he couldn't leave anymore. He looked at Liu Tongen depressedly, wanting to hear what was going on.

Liu Tongen smiled and said, "The main reason I invite you here this time is not to correct error coding, but to talk to you about mathematical problems."

"Math question?"

"It's information compression, transmission, and multi-data positioning calculations."

Liu Tongen gave a general explanation, and then asked, "Have you ever understood information compression?"

Zhao Yi nodded lightly.

Liu Tongendao said, "Our satellite performance is still high-end, definitely at the top international level, but there are still big problems in signal compression and transmission. The main reason is the lack of support from mathematical theory."

"There is a new digital compression technology in the world. Have you heard of it?"

Zhao Yi continued to nod. Of course he had heard of it. It was designed by him and Terence Tao, and they also applied for a patent. His name was on the patent.

Liu Tongen thought that Zhao Yi probably didn't understand, and the nod was just symbolic, so he explained carefully, "We hope to use algorithms to improve the performance of satellite cameras, that is, to allow satellites to be launched in the future to capture more precise images." The efficiency is higher, it can store and transmit more image data, and it is also hoped that the positioning can be more accurate."

"The latter is easier to say. It only requires more data to perform calculations, while the former requires the support of a systematic mathematical theory."

"Previously, our program design was a bit confusing, with multiple sections spliced ​​together. We wanted a systematic compression technology..."

Liu Tongen explained it carefully. The general meaning is that the efficiency of data transmission is too low due to algorithm problems. He hopes to have a mathematical theory to support the development of a new compression technology, which can be placed on satellites to improve satellite data capture. , transmission and other aspects of performance.

Zhao Yi kept nodding along as he listened.

After Liu Tongen finished explaining in detail, he said, "It is definitely not possible to use traditional algorithms. The fundamental way to improve performance through data compression is to simplify the amount of information in the captured data and increase the amount of information in the analyzed data."

"It's better to make decompression more computationally expensive than compression."

"Mathematically speaking, it is to use simple information to shape complex functions. We only need to record the simple joy, and then analyze the complex functions when decompressing..."

"right!"

"Is such that!"

"That makes sense!"

When Zhao Yi was explaining mathematics, several professors gathered around. At first they just listened to what the two were talking about, but after Zhao Yi opened his mouth, it seemed to become a personal class.

Others can only shout "that's right", "that's right", "makes sense", "that makes so much sense", etc.

They were also surprised.

Data compression is a field that is closely integrated with computers and mathematics, but in terms of mathematics, it should be divided into applied mathematics.

Zhao Yi is indeed one of the top mathematicians, but his area of ​​expertise is number theory research, not applied mathematics.

There are so many areas of mathematics.

Many mathematicians in China are doing complex mathematics, such as partial differential equations, topology, differential geometry, etc. There are several academicians in this field.

Number theory research and complex mathematics are linked to a certain extent and can be said to be very closely related to each other.

Applied mathematics is different.

Applied mathematics is more closely related to complex mathematics than to pure number theory.

They really didn't expect that Zhao Yineng could also do research in applied mathematics, and that after hearing Liu Tongen's explanation, he would be able to follow up with so many things.

The people around him, including Liu Tongen, could only nod, and sighed in their hearts, "As expected of Zhao Yi!"

"It's really awesome!"

"This is the level that can win awards internationally!"

"..."

After Zhao Yi talked about some mathematical theoretical issues of data compression, Liu Tongen's eyes lit up when she looked at him, "Follow me."

He took Zhao Yi to the small office next to him, and then stated his purpose, "In the name of associate designer, I formally invite you to join the work of the national navigation team."

"ah?"

Zhao Yi suddenly felt a little uncomfortable. He felt it was too formal. "Have I not done projects before?" He was referring to helping the Intelligence and Automation Laboratory to do program design work, some of which were for the National Navigation System. project.

Liu Tongen shook his head and said, "I mean, let you start the project on your own. As I said just now, we need a mathematical theory of data compression. I think your ability is enough to take over this project."

"this……"

Zhao Yi was a little hesitant. This was his first time experiencing such a thing.

Liu Tongen smiled and said, "Don't be too stressed. This is not something too confidential. Data compression is a technology, not decryption. It doesn't matter even if someone knows about it. We are just increasing the performance of transmitting data. Related The technology can be popularized for civilian use.”

Indeed.

After the digital compression technology designed by Zhao Yi and Tao Zhexuan applied for a patent, several large international commercial companies were discussing the use of the patent.

This is actually like communication technology, which can be used in any aspect, but because there was no mathematical theory for data compression into a system in China before, he was asked to do a related research.

Zhao Yi thought about it and agreed.

It's easy for him.

He only needs to take over the mathematical theory of digital compression technology and apply it mechanically.

Of course.

Because the uses are different, the mathematical theory also needs certain modifications, but overall there is not much difference.

The results won't be published publicly anyway, so it doesn't matter much.

When Liu Tongen saw Zhao Yi nodding, he breathed a sigh of relief and smiled, "I will be responsible for this project. I will sign you up for a big project. When it is completed, don't publish the results. I will definitely give you corresponding rewards when the time comes." compensate."

"good."

Zhao Yi doesn't particularly care about compensation. What he cares about is that the work should not be too complicated and affect his college life.

If he suddenly had to work and study all day long, it would be unacceptable. In his plan, he would not officially enter a busy job until he was at least thirty years old.

Around twenty years old...

Youth!

This is the best time in life, and you can’t spend all day working.

…

Zhao Yi went back in the same car as Liu Guangzuo.

On the road.

Liu Guangzuo asked, "Did you accept Academician Liu's project?"

"you know?"

Zhao Yi was a little surprised.

Liu Guangzuo smiled and said, "How secretive do you think it is! Don't listen to that old guy's surprise. Domestic compression technology lacks the support of high-end mathematical theory. It is not a secret in the academic world. I knew it when you just talked about it. .”

"oh."

Zhao Yi felt that he had been deceived. He thought he had joined some secret project, but it turned out to be something everyone knew.

Liu Guangzuo commented, "It's pretty good."

"Why?" Zhao Yi didn't understand, "How much can the project funding be?"

Liu Guangzuo hesitated for a moment, "Nowadays, projects with this kind of mathematical theory don't have much funding. This theory is very important, maybe two or three million? The advantage is that the funding will not be held accountable. Once the money is in your hands, it will be all It's yours."

Zhao Yi was a little surprised, "So good?"

Liu Guangzuo looked indifferent, "This is a high-end mathematical theory that is lacking in China. Systematic mathematical application theories are very rare, especially those that can be directly applied to the Internet."

"Think about it! A small component of a satellite may be worth tens of millions. The applied mathematical theory that can improve performance is not much, right?"

"It makes sense." Zhao Yi nodded.

"It is not easy to create a complete theory like this." Liu Guangzuo guessed, "Academician Liu should not only have found you, but also others, so don't put too much pressure on this project. The good thing is, whether you succeed or not, the money is yours."

"..."

Zhao Yi really has no pressure at all.

Academician Liu came to him just to give him money and buy hope of "possible success in the future"? He had just learned that doing research in academia was such a good thing...
