metaverse evolution.

After finding the bug that the Wei family was researching, Chu Fei showed a bright smile, but he did not stop there, but needed to prove it carefully.

In scientific research, we cannot just have "the power of my own thinking", that is not enough.

In fact, many times, scientists have some intuition and vaguely know the problem, but because they cannot lock down the specific details, or find no solution, or cannot implement alternative theories, they have to let it continue to exist.

This situation is actually common.

Therefore, Chu Fei found the problem, but it was not the end. It can even be said that Chu Fei has finally reached the starting point of complex algorithms and has just begun to get started.

But before sorting out this bug problem, Chu Fei also took the time to sort out the data he decompressed the cosmic brain, etc. This was agreed upon yesterday.

In scientific research, theory alone is not enough; detailed data is required.

The theory is like a skeleton, but what is restored based on the skeleton may be very different from the actual situation, and may not even be the same species at all.

For example, various "paleontological restoration maps", let's talk about bulldog skeletons, can create images of ferocious monsters on this basis, and ensure that every data is reasonable and consistent with scientific argumentation.

Therefore, Wei Weiya needs the data that Chu Fei has personally experienced to improve the situation after the decompression of the cosmic brain and exercises, especially the problems Chu Fei faced in his practice and the solutions at that time.

Fortunately, Chu Fei is very familiar with these data. Even if he was negligent at the time, looking back from today's height, he can make up for the data at that time. Even looking back, the data may be more accurate.

It only took half an hour to sort out the data, and Chu Fei continued to study complex algorithm problems.

It was after noon that Chu Fei finished his lunch and on his way back, he met a researcher yawning and walking towards the research center.

After seeing Chu Fei, the man yawned even louder, said lazily "Good morning", then Shi Shiran passed by Chu Fei, came to his work station, and lay down on the table first. Had a nap.

Chu Fei: ...

Is it early? Looking up at the hot sun above my head, I happened to see Lan Wenchuan approaching and said "Good morning".

Lan Wenchuan glanced at Chu Fei and frowned slightly, "Young man, don't be so lazy."

Chu Fei: ...

He looked at the sun in the sky again, eyes wide open.

Half an hour later, Wei Weiya came over, but the old man actually had a candied haws in his hand, which was delicious.

Am I in the wrong place?
Wei Weiya looked at Chu Fei standing at the door in a daze, nodded, and went in.

Chu Fei quickly said: "Senior, I have sorted out the data mentioned yesterday and put it in the virtual space, in the account of the virtual cabin I used."

Wei Weiya stopped and said in a slightly excited tone: "Is everything sorted out?"

"There should be no omissions. However, the data may be a little... um... messy. I sorted it out strictly according to my practice process, so that the process will be more comprehensive. But there are always various problems in the whole process."

Wei Weiya nodded and continued walking, even eating a candied haws. As an elite researcher, he was not afraid of Chu Fei manipulating the data, he could check it out.

Chu Fei spoke again: "Senior, I read all the basic information on complex algorithms last night and found a possible bug, but I'm not sure."

Wei Weiya stopped and took a serious look at Chu Fei, with a look of doubt on his face: "You read all the materials in one night? Three thousand volumes of formal research materials and one hundred thousand notebooks?"

"Yes!" Chu Fei answered decisively.

In order to get to the core of the complex algorithm as soon as possible, Chu Fei had to reveal a little secret.

If you want to join Wei Weiya's research team, you can't just go through the back door.

The most important thing in scientific research is research ability. If the research ability is not up to standard, Wei Weiya may not even be interested in opening his eyes. Yesterday's experience is the best proof.

However, as an old scientist, Wei Weiya was still very rigorous and didn't talk nonsense. He directly asked Chu Fei a few questions, each one more tricky than the last. Chu Fei answered fluently.

This time, Wei Weiya looked at Chu Fei in shock, "Such a strong learning ability?"

Chu Fei smiled and said nothing.

"No wonder you have such cultivation and so many achievements at such a young age. What a learning ability!" At the end of the sentence, Wei Weiya couldn't help but sigh.

The most important thing in big data practice is knowledge, and knowledge requires learning to master.

In other words, learning ability is the "qualification" for big data practice!
In Wei Weiya's sighing voice, Chu Fei also sighed, "Senior, do you know the environment in which I studied?"

"I've known it for a long time. It's all clear in the intelligence. Dawn Academy, Whip Education.

But now I roughly understand that Shuguang Academy and Wu Yong are not cultivating elites at all. They are actually looking for a learning genius.

Using the whip squeezing method can squeeze learning ability as much as possible, thereby activating the nature of people with real learning ability and standing out.

Very cruel approach. But it works.

In this way, you can be regarded as one in a million. "

Chu Fei smiled bitterly and said nothing. This is the reality.

But having said that, if it weren’t for Wu Yong, I wouldn’t be where I am today. Even if you have the seeds of the Tree of Wisdom, you still need a place to study. At that time, Shuguang College was indeed the best choice.

Even now, the main direction of the wisdom tree seeds is still learning, which requires a lot of knowledge.

Wei Weiya spoke with a very solemn attitude: "Come sit here and tell us about the problems you discovered."

The surrounding researchers pricked up their ears to listen.

Chu Fei sat down and said seriously: "The bug I suspect is a typical triple star problem."

Unexpectedly, as soon as Chu Fei's words came out of his mouth, Wei Weiya sighed, "You discovered this."

Chu Fei was surprised at first, and then suddenly realized, "Senior, have you known about this problem for a long time?"

Wei Weiya clicked his tongue, "First tell me your opinions, ideas, and even solutions."

Chu Fei nodded and began to explain: "Let me first talk about the important core of the entire complex algorithm, which is the lowest level logic, which is: movement!

This is a dynamic model. Compared with the static model, it has inherent advantages and the dimension is naturally higher.

But there is also a bigger problem with dynamic models, which is accuracy.

Obviously, the accuracy in sports mode is not as good as that in static mode. Moreover, the calculations in the sports mode are more complicated, which is beneficial to the construction of complex algorithms, but it also further aggravates the problem of insufficient accuracy. "Hearing what Chu Fei said, Wei Weiya nodded and looked at Chu Fei with a look that seemed to be more serious.

At this time, the surrounding researchers also gathered around and listened to Chu Fei's explanation.

Chu Fei took a deep breath and continued: "In order to solve the shortcomings of the motion problem, we have to adopt mature logic. The most mature and stable motion logic at present is undoubtedly the solar system operation model.

However, the solar system motion model, or the star system motion model, cannot avoid a core problem: the triple star problem. "

A researcher couldn't help but speak, "We are using the ideal mode of star system operation. There are indeed problems as you mentioned, but they are not considered bugs. We have corrected possible problems."

Wei Weiya knocked on the table, glared, snorted softly, and then said to Chu Fei: "Continue."

Chu Fei also glanced at the researcher and nodded slightly, "The problem lies in this ideal model. The ideal model itself is wrong!

The so-called ideal model is a hypothetical perfect state. The significance of setting up an ideal model lies in better learning and understanding, rather than following a script.

Using the so-called ideal model is surreal. This is a typical problem of believing in books rather than having no books at all. "

Chu Fei said this a bit rudely. But Chu Fei still said it. Since you dare to take the lead, I will step on you and move up without negotiation.

Of course, Chu Fei nodded before speaking, which could be regarded as saving some face.

After a pause, Chu Fei continued: "We study complex algorithm computers to solve real-life problems. This itself cannot be solved by an ideal model.

If we follow the ideal model, the current physical world will collapse. In other words, using an ideal model can make the problem more troublesome.

Everything based on the ideal model theory is a sand sculpture built on the beach. "

Sand sculpture...

A certain researcher who just spoke looked at Chu Fei and something was wrong.

However, Chu Fei didn't care about this and was still explaining: "I carefully looked at the complex algorithm we have here. The first and most important thing is to establish a carrier.

Just like painting requires paper, the operation of this complex model also requires a carrying logic.

This is the Riemannian geometric space built with Riemannian geometry as the core, and this space is used to simulate space-time. This works very well, at least I haven't noticed any problems for the time being. If there is, it is not enough to describe the ultra-three-dimensional world, but it is more than enough to run a solar system model.

The problem lies in the solar system model.

It is generally believed that in the solar system model, the position of the stars, that is, the sun, is constant. However, in fact, the center point of the solar system is not the center of the sun, but is located about 4.6 kilometers away from the sun's surface.

Why do we say "left and right"? Because there are too many celestial bodies in the solar system, celestial bodies interact with each other, and the center point of the solar system is changing all the time.

Even because of gravity problems, the sun itself is not a standard sphere, and all the celestial bodies in the solar system are not standard spheres.

This is an inevitable phenomenon caused by the laws of space and time. It is this change that causes the environment on the earth to be different every day.

If we forcibly eliminate this change, we can certainly get a good logic of a complex algorithm, but when the calculation accuracy continues to improve, when it reaches an accuracy of one part per billion, an error will be reported.

The accuracy of one part per billion refers to the ratio of 4.6 kilometers to the radius of the solar system. I did some accuracy tests last night and basically verified them.

The precision of one part per billion is of course not used normally. However, in the field of scientific research, in high-precision fields, especially when sprinting towards the ultra-three-dimensional world, we often encounter or even exceed it.

If one or two data are wrong, the computer may be able to correct them automatically.

But when the computing power of the computer reaches Beijing-level computing power, and when the calculated data reaches Pb level, more than one error will occur almost every second.

Therefore, I think today’s computers with complex algorithms will enter a protection state within three seconds at most once the accuracy reaches one part per billion. "

After Chu Fei finished speaking, everyone fell silent.

After a while, Wei Weiya spoke, "You are right, this is indeed the case. But the question is, how to solve it?

We have thought about replacing the binary star system, simplifying the number of cores, or continuing to increase the proportion of cores, or downgrading to a Jupiter and ring structure, and even thought of neutron star systems, and wanted to learn from the electron cloud structure, etc., all of which have problems of one kind or another.

In fact, it’s not just us, other teams or organizations that study complex algorithms have encountered similar problems.

Even our research accuracy is among the best.

Do you have a solution? "

Chu Fei nodded and said word by word: "If one system is unstable, there are only two systems, which are mirrors and yin and yang to each other. As the saying goes, one yin and one yang are called Tao, and this can also be handled in this way.

To put it simply, the logic of parity conservation is introduced to form a binary logic of one positive and one negative.

Our logic as a whole is based on the logic of gravity, and the conservation of parity is completely established under the conditions of gravity. "

A certain researcher who had just spoken spoke, with a hint of ridicule in his words: "We have already discussed the direction you mentioned. The theory is feasible, but in actual research, it makes people feel like a tiger eating the sky and having nowhere to eat. .

The logic itself is already complex enough, and introducing a complex logic has exceeded the basis of existing knowledge. The most important thing is that the hardware does not support it. "

Everyone around them nodded, even Wei Weiya nodded, and said with some emotion: "Chu Fei, it's good that you have such an idea, it shows that you have indeed done research and want to make some contributions.

But we have studied complex algorithms for decades and discussed them with thousands of researchers.

It can be said that we have tried every method we can think of, even some seemingly unbelievable methods. But none of them worked. "

As he spoke, Wei Weiya's voice became much lower, "The super three-dimensional algorithm may really exceed our capabilities."

Chu Fei was very motivated, "What about banks? How do banks solve complex algorithms?"

Wei Weiya: "Their advanced computers are obtained from further inland and cannot be parsed. In fact, banks need to pay expensive usage fees when using these computers.

In other words, our bank here, despite its appearance, is also a workman behind the scenes. "

Technology monopoly!
Such a word came into Chu Fei's mind. No wonder banks are also involved in research on “open source” projects. Of course, sucking blood is part of it, but the other part is probably a helpless choice.

After thinking for a moment, Chu Fei spoke in a loud voice: "Senior, I can't find a better solution for the time being, but I am confident and determined to tackle this technology. But I need more information."

Wei Weiya took a deep look at Chu Fei and said, "You want more information, right?"

"I do not deny!"

Wei Weiya: "However, these materials have been accumulated bit by bit over decades, and have brought together the wisdom of countless elites. The resources and wealth consumed during the research process are difficult to estimate. Therefore, if you want to obtain this knowledge, you must be demanding. Conditions." (End of chapter)
