Chapter 73 Grandmaster

"The more flexible the deck is, the weaker it is for the computer..." Kaiba pinched his chin, then nodded and said, "How did you come to this conclusion?"

"It's just a little mathematical principle, very simple." Lihua pushed up her glasses and then explained: "No matter how many cards there are in each deck, the final result produced by the computer is just a sequence, and if If all the cards in the entire deck plus the opponent's cards are added to the calculation, then the question of which card the computer will use can be solved: the first card is easy to calculate, but the second and third cards are slightly more difficult. Do the math, and when it comes to the fourth and fifth cards, since more than four variables need to be used to calculate, the calculation amount for the computer will increase exponentially - so I would venture to guess here that your group The Duel Terminal does not use such resource-wasting algorithms.”

Haima remained silent, which seemed to be what Yuan Lihua had inferred.

"So there will be a simpler algorithm - every card used by the computer is only related to the card it or the opponent used before, or the previous cards." Yuan Lihua shrugged, "This way Although it is lazy, it does have its advantages. At least it will be easier for the computer to remove the card; although such an algorithm saves resources, there is a problem, that is, as long as it involves more When operating the card, the computing speed of the computer will decrease; that is to say, for the computer, the less relevant cards are used, the more powerful the connected card group will be, and the card group that requires the use of a lot of cards will be A deck with high flexibility for linking is the computer’s weakest item.”

"Is that so..." Kaiba nodded after understanding, "From this point of view, among the nine decks, which ones do you think are the strongest in the hands of the computer?"

"Dongfeng Guhui's 'Transformation Ninja' usually only requires one or two cards to complete the operation, but sometimes it will change the wrong monster; Luo Likong's 'Loli King' often only needs to control the back The trap card on the field; and..." Yuan Lihua raised her lips, glanced at Seto Kaiba and said: "And Seto Kaiba's 'Blue Eyes Triumph'; in addition, I really like Katsuya Jonouchi's 'Change Fate'. It’s impossible to calculate it clearly—things like luck have always been a matter of metaphysics and not a subject of mathematical research.”

The corner of Kaiba's mouth twitched slightly - indeed, Jonouchi's strong luck often falls into the unreasonable category, and it is really difficult for a person who studies mathematics to study this thing.

"The above is all my answer. Mr. Haima, are you still satisfied?" Yuan Lihua held her eyes and said calmly: "If you are satisfied, please let me leave; if not, please let me go." Leave - I really have nothing more to say."

Kaiba turned sideways slightly, and the girl with glasses left with standard steps - if someone measured her steps, they would know that the distances covered by each step were strangely the same!

"It's really interesting..." Kaiba looked at the direction Yuan Lihua left, then turned back and said: "Li, take Hui and Yukino back... Hey, what's wrong with you?"

When the president turned around, he saw two small faces with "confused" written on them... Obviously, after listening to Yuan Lihua's theory, Jiu Yuli and Fujiwara Yukino looked confused, while Xiao Hui did not. , but she didn’t seem to have the desire to explain on her own initiative.

After all, the half-spirit girl usually doesn't like to talk. This kind of thing requires a lot of words to explain. She has also seen it in "Calculator Man". She still doesn't understand something, how can she take the initiative to speak out?

Just when Xueno was confused, Xiao Hui patted her shoulder slightly and gave her directions: "If you don't understand, just ask, ask Li Zheng."

Only then did Fujiwara Yukino remember that she still had a cheating ghost (Li Zheng: Hey, hey, hey, it was just that the majesty value was wiped out a few times. When did it evolve into a cheating ghost!), so she hurriedly answered the call. After meeting Li Zheng, Li Zheng, who had also heard Lihua's description before, silently explained: "Actually, it's just a probabilistic statistical algorithm transplanted into the game, using a variant of the hidden Markov model..." 】

["Forget it, you'd better stop talking. I'm really sorry that math is my worst subject."] As soon as Li Zheng opened his mouth, Yukino stopped hastily. She felt that it was a mistake for her to figure this thing out in the first place... ...["However, that guy is so young, but he is really a genius in this aspect..."]

Li Zheng shrugged, but z-one, who was sitting next to him, spoke up, "Actually, if it were her, it would be normal for her to understand these things at the age of twelve."

"Oh?" Li Zheng turned to look at z-one, "Do you know her?"

[By the way, this guy comes from the future. Could it be that this "Yuan Lihua" will be a famous genius in the future? ] Li Zheng thought, but after Li Zheng expressed his doubts, z-one shook his head and said: "More than just knowing her - she is the 'grandmaster' of my profession. I have killed her 24 times. Saved her 26 times.”

"Kill? Save? 24 times? 26 times?" Li Zheng noticed these actions and quantifiers, "And, 'Master Patriarch'? Could it be that she has something to do with the 'doomsday' in the future?"

"It's not just a relationship - in the 'official history' without any interference from me, although Yuan Lihua only lived for 34 years, she was the founder of the theoretical basis for the later planetary particle perpetual motion machine. She proved this perpetual motion machine mathematically and obtained funding to conduct research on perpetual motion machines on her 34th birthday." z-one continued: "Then the next day, Yuan Lihua was assassinated on the way to her new laboratory."

"Assassination? Who did it?" Li Zheng simply found it unreasonable - please, that is a perpetual motion machine. If it is really built, it will be the greatest invention in human history, and the founder of the perpetual motion machine theory is the greatest treasure given to mankind by God. Kill her? I wonder how many people will cry in the toilet?

"The people from the extreme environmental organization, the one who finally took action was a close friend of Yuan Lihua, a popular actress." z-one took a sip of the wine he won from the casino with the lottery system, "He tampered with the car and died together with the genius mathematician; later Lihua's student completed the perpetual motion machine."

"Student? Could it be Fudo Yusei's father?" Li Zheng had watched "Yu-Gi-Oh! 5DS", so he naturally knew who the real person who created the perpetual motion machine in the "official history" was.

"That's right." z-one nodded: "Fudo Gendou, a genius in quantum physics, although in my opinion he is still a little bit behind his teacher."

"..." After hearing this name, Li Zheng complained: "I know why Fudo Yusei can't save the world - it turns out that this guy is a Gundam driver..."
