"Yo, what's the matter? You're like an old-fashioned CRT TV with a broken antenna, the picture is covered by noise from time to time. Do you want to go to the factory for repairs? I strongly recommend you reincarnate again and return to Earth directly if you have the chance. "
The one who spoke was, of course, the fat one. Lin said unhappily: "I'm already sick and in pain. Can't you say something nice and use a better analogy?"
"Then, the analog knob is not very good. How do you adjust the radio that can't even adjust the channel?"
… It seems that I'm too demanding, Lin thought. Ignoring the fat one, Lin asked: "Did I do anything before I came down?"
The chuunibyou clone said calmly: "It seems that you really forgot something."
"I forgot something?" Lin repeated. Of course, he was also curious and puzzled about the content of the conversation: "You said that I forgot, that is to say, you still remember those things. Aren't we the same person? Why are there things that only you know, but I don't know? Just like how you killed the invading nightmare creatures here. If I hadn't come in and encountered them, I wouldn't have known about these things. "
"We are your subconscious. Some unimportant things, some things that shouldn't be remembered, whether good or bad, you forgot, but we still know about them. This is a very normal thing. Otherwise … "The fat otaku clone grabbed the chuunibyou clone," … do you want to remember what dark history you left behind in this era? "
"No, I was wrong, please forgive me. Let's forget about this topic. " A certain person withered. Don't think about things that should be forgotten. "… I just want to know what I did before …" Before he finished speaking, new decorations on the second floor of the Magic Tower attracted Lin's gaze.
For Lin, who has been studying this aspect of craftsmanship for a long time, although it wasn't clear at a glance, but after a little thought, he more or less understood its function. Soon, Lin Li understood the purpose of the magic array he had carved on the second floor.
"This is … principal component analysis?" After understanding what he had done, Lin also recalled most of the causes and effects of his actions. He walked around the Magic Tower, confirmed the logic of the program that has been carved, and learned that the completed part is not complete.
This didn't mean that the principal component analysis was incomplete. In the field of data analysis, whether it was algorithms or other tools, there was only the most suitable one, not the best one. In other words, each method had its own conditions. Therefore, if one wanted to reach a certain level in this field, one would not be able to travel the world in one move. Mastering the use of multiple methods was the absolute truth.
In other words, the program on the second floor was merely passable. It had not reached a complete level, let alone a level of perfection that was impossible to achieve. How could a program be perfect? It was all about finding bugs, updating, finding new bugs, and updating again. After accumulating enough updates, it would be revised. Those that stopped updating and modifying the game were either because the company that maintained the game had collapsed, or they had released something new and released the old game.
Therefore, there was still a long way to go. However, Marco Lin didn't want to start work now. His body wasn't in good condition. Besides, there was still someone waiting outside for an answer. If he let her wait too long, it was hard to predict what would happen.
However, before he left, he saw that a part of the program code was quite strange. It wasn't part of the PCA (principal component analysis) program, and it didn't seem to have anything to do with the logic of automatic loops and automatic updates. It was like a redundant and useless program code. This wasn't a test program code, either. It was used to check if the program output was correct.
He couldn't figure out how this program could help this large piece of mathematical logic, and it might even cause a misjudgment. Therefore, Lin Da waved his hand and deleted this large piece of program code. The first step to simplifying and optimizing was to dare to delete things, wasn't it? After doing all this, he felt much more refreshed and left the dream.
Seeing the original body leave, the fat otaku clicked his tongue. He didn't think much of the mod that he had worked so hard to complete being deleted. Guo Zhongsheng said, "It seems that even if it's not explicitly stated, he will have an intuitive reaction to things that we subconsciously know."
"Goddamned dog, you don't know how to empathize with people. You deserve to be stuck in this life."
"You're self-destructing. The original body was raised outside, and she was also a domineering older sister. Yan Ran was a successful person who had escaped from Africa and entered Europe. As for Lu, it's the two of us who can only stay in the dream, unless we're gay. But if you dare to have that kind of disgusting thought, I'll stick this unfinished magic tower in your ass. "
"Huh, this seems quite interesting. Want to try? "
Guo Zhongsheng gave the fat otaku a look of disdain and gradually disappeared from this space. The fat otaku clicked his tongue again and said, "The chuunibyou self is so boring."
In the real world, Lin Da opened his eyes and looked at the flickering flames of the bonfire. After a while, Lin Da's lifeless eyes refocused.
Sensing that someone had returned from the dream, Fen asked, "How is it, do you have an answer?"
"Mhmm." Lin Da nodded and organized his thoughts. He then told Fen about his thoughts and what he had done. Fen was very surprised by his answer. "I've never thought of using mathematics as an approach."
"This isn't a surprise. In a maze without mathematics, no one would be used to using mathematics as a solution. But in fact, the ultimate explanation for everything in the world is in mathematics. If there is something that can't be explained, it only proves that there are places or phenomena that we haven't observed yet. "
"Then there are higher dimensional creatures."
"Yes. Explaining those existences from this perspective can also explain why they can't move freely in this world. Because if higher dimensional creatures want to move in the three-dimensional world, they must reduce their dimension or rely on projections. – "
Take humans living in the three-dimensional space as an example. If they want to become two-dimensional, they have to draw themselves into a picture, or a comic, or even an animation. These are all methods of projection.
As for reducing their dimension into two-dimensional creatures, it's either absent-mindedness, like a ghost living in a painting; or it's science fiction, where they turn their consciousness and memories into something like a computer virus, living between the screen and the network. And these are not easy things to do, they only exist in fantasy.
"– No matter which method it is, it has its difficulties and shortcomings. Secondly, how the information they provide will be understood by humans. This is related to everyone's subjective perception, that is, belief. And when the subjectivity is occupied by fear, evil, and other emotions, then the appearance they present will be terrifying and evil. "
"So, using mathematical methods, they reduce their dimension." Fen added, but was somewhat hesitant.
"That's not accurate. It should be said that using mathematical methods, after reducing the dimension of the information they provide, it is transformed into a form that we can understand. It's not that we reduce their dimension, we can't do that. In the past, people used the form of belief or learning related knowledge to try to get close to and understand them. But this involves too much beautification or ugliness of the subjective consciousness, rather than the truth. Using mathematical methods to reduce the dimension is to try to find important information from a lot of information, combine or selectively delete similar information, and finally leave the 'most suitable' explanation, which we can then understand. This seems to exclude the influence of subjective consciousness, and may be closer to the true appearance, but in fact, what we see in the end is still not the most primitive one. Also, different methods and different parameters will bring about different results. "
"So, no matter which method it is, it's not the truth. It can only be said to be a perception close to the truth to some extent. "
"Yes. That's accurate enough. But the average person can only use the former method to try to understand. The latter method has to rely on auxiliary means to be realized. And I relied on the computing power of the magic tower in the dream to see the world after I reduced the dimension. But what I can't understand is why I seem to be able to not only see it, but also walk in it. "
Even Fen, a genius from a thousand years ago, spent a considerable amount of time digesting what Lin said. Compared to the possibilities she knew, and everything she had experienced, all kinds of experiences were not enough to overturn what Lin said, and they even continuously confirmed the correctness of those words.
The understanding of the gods by mortals was just that unpredictable. Everyone had their own set of explanations, and those mortals who served the gods also had their own set of understandings. As for Fen, who had slain a god and even touched the threshold of that door, she had a deeper understanding.
As long as he could cross that small gap, perhaps his life would be completely different. She reckoned that she would be among the evil gods, and she would have to fight against kindness for the rest of her life until she died.
But the world that she could see after crossing that step did not attract her. Or rather, after the flames of revenge burned her to ashes, all that was left was a muddle-headed empty shell. Until today, she felt like she was alive again. Was it because she discovered a new world and obtained the knowledge of the new world? Or was it because …
"Cognition." As if to prevent herself from admitting something meaningless, Fen shifted her focus. She used her perspective to explain Lin's problem. "I once said that magic is about using power to command, to change the status quo or cognition. The experiment with the Featherweight Spell that I did with you before was a kind of magic that changed cognition. "
It was a very interesting experiment that they did when they were in the Tower of the Great Sage. The experimental material was a very heavy box filled with precious metal coins. Even Hercules would find it difficult to lift a wooden box filled with precious metal coins. Fen cast a First Circle Apprentice spell in front of Lin and Kaya — Featherweight Spell. As expected of a Lich, Kaya, who was very thin at the time, easily carried the box.
Then, she let Hallumi, who was not present, in, which meant that the box had been cast with Featherweight Spell. However, no matter how hard the blonde girl tried, she could not move the box at all because it was too heavy.
What was more interesting was that from the beginning to the end, using a standard method to measure the weight of the box, before and after the Featherweight Spell was cast, the weight remained the same. The only thing that changed was the 'human cognition'. And this change brought about a completely different result.
