Chapter 192 Infinite Monkey Theory (Second update)
“This is a man-machine battle held by the Go Club. His name is Yang Shengli.” Li Li secretly pointed at the gentle boy playing chess and said: “He He is the president of the Go club. He is the best in the school. It is said that he has passed the fifth level of amateur Go. He is also a master of physics in our school."
Li Li secretly pointed at an older boy standing next to the computer. Said: "His name is Qi Bo. He is a Ph.D. in the computer department of our school and a member of the Go club. He compiled a program to play Go. It is said that he defeated an invincible player. Yang Shengli was dissatisfied, so he agreed to compete today."
“He made it up himself?”
“Yes, it’s very powerful.”
Fang Minghua glanced at the boy again, looking at the screen with a calm look, but his messy hair was particularly eye-catching.
“What about this computer?”
“It’s a computer from their laboratory, secretly brought out.” Li Li chuckled.
You are brave enough.
A computer in this era is worth tens of thousands, but it is the treasure among treasures.
"Win!"
A burst of cheers suddenly came from in front of the computer, and the boy wearing glasses who was playing chess stood up and looked at Qi Bo next to him, with a somewhat arrogant tone:
" Qi Bo, you said that the program you wrote is very good, but I don’t think it’s very good. I can make it two times.”
Qi Bo was not frustrated, but looked at Yang Shengli and smiled: “ This computer is 286, and its computing speed is not good. The English name of the chess machine "Deep Thought" developed by the team at Carnegie Mellon University in the United States is said to be able to reach the level of international stunt masters. It uses mathematics. The brute force algorithm (exhaustive method), you must understand the principles if you study physics.”
Yang Shengli became silent.
"What do you mean, if computers run fast enough and are advanced enough in the future, the software can defeat people?" asked a classmate next to him.
Qi Bo nodded and continued.
"It's not the future, it's now! If I didn't have a 286 microcomputer, but a computer like "Shenzhen", I can't say that the program I compiled could beat Nie Weiping, but it could beat us amateurs. There is no problem with the players.”
Fang Minghua stood at the door and just listened quietly.
This is all true.
Isn’t there a very popular Go artificial intelligence Alpha Dog in the future? It is said that he defeated all the top Go masters.
Ke Jie, the world's number one Go world champion at the time: "In my opinion, it (Alpha Go) is the God of Go and can defeat everything. For AlphaGo's self-improvement, humans are too redundant.
Later I heard that AlphaGo looked like machine learning, but in essence it also used brute force algorithms.
But this involved the future, and he was a layman in technology, so Fang Minghua naturally couldn't speak up. .
At this time, Li Li suddenly said: "My tutor, Professor Xu, said that the French mathematician Emile Borrell once wrote a book about probability, which has always been famous in the scientific community. A conjecture like this is to let countless monkeys sit in front of typewriters and tap the keyboard randomly. If there is no time limit, then they will one day type a "Complete Works of Shakespeare". This is actually an exhaustive method. ”
"Li Li, you are right." It seemed that Qi Bo knew Li Li. He cast admiring glances at him at the door, but suddenly noticed Fang Minghua next to Li Li, with a strange look in his eyes.
Li Li's words attracted the attention of other students, and soon someone recognized Fang Minghua.
“Isn’t this the writer Minghua?” Someone quickly recognized it, and there was a commotion in the classroom.
Fang Minghua quickly smiled and said that he came to school to see Li Li for something. I don’t know anything about Go, so you can continue playing.
"Let's go, Li Li, I have something to do with you." Fang Minghua whispered, gently tugged on the girl's sweater sleeve, turned around and was about to leave, this tiny movement fell on the In Qi Bo's eyes.
Seeing Li Li following Fang Minghua to leave, he suddenly shouted.
"Fang Minghua!" Fang Minghua had no choice but to stay and turn around to look at the other person.
"You are engaged in literary creation. Have you heard of what Li Li just said?"
Fang Minghua nodded.
Qi Bo's expression suddenly became a little excited.
"Have you heard of it? That's good. A monkey typing out the Complete Works of Shakespeare is just a metaphor. According to the infinite monkey theory, all human literary works can be written!"
Listen Qi Bo's slightly excited tone made Fang Minghua vaguely wonder why Qi Bo emphasized what Li Li said.
Sure enough, a little boy said: "According to your opinion, all writers including poets will be unemployed in the future?!"
Qi Bo nodded proudly and looked again Written by Fang Minghua: "Are you right?"
Oh?
What does it mean?
We have no grievances, right?
Where is the irony in your sentence?
Fang Minghua looked at the other person's eyes and occasionally glanced at Li Li standing next to him, and suddenly understood something.
Are you jealous of the wrong person?
Li Li also heard the meaning of Qi Bo's words, and her pretty face suddenly turned cold.
I just thought of saying it casually, but I didn't expect that he would use it as an excuse.
"Qi Bo, what do you mean?"
"It's not interesting, I just want to discuss this issue with him." Qi Bo looked innocent.
Fang Minghua smiled and said: "The infinite monkey theory is just a hypothesis in mathematics, but literature is not mathematics. Whether it is monkeys or computers, they may be able to write novels or poems in the future, but it is impossible to write as beautiful as Li Bai "The reason?"
"Let's take a simpler poem as an example. There are only two ways for a monkey to be like Li Bai or surpass Li Bai. : First, write the poems that surpass him; second, write all the poems!
Is this the truth?”
Qi Bo thought for a moment and nodded: "Yes, this is a mathematical brute force algorithm (exhaustive method), the same principle as when I write a Go program."
"Li Bai is good at five-character poems and seven-character poems. He can further write all the words of common word patterns, so that he can surpass Su Dongpo. In order to achieve this goal, he should try all the combinations of Chinese characters in the poems that conform to these rhythms, right?" Fang Minghua said. A follow-through approach.
“That seems to be the case.” Qi Bo nodded again.
Fang Minghua smiled and looked at Qi Bo: "Do you think it's possible?"
Before Qi Bo answered, Yang Shengli, who had been listening to the conversation between the two, suddenly screamed: " Impossible!"
"Why?" A girl with a ponytail asked inexplicably: "A lot?"
"Of course there are many!" Yang Shengli said with a smile, "Let me ask you, write one poem each of five-character and seven-character poems, as well as those common word cards. How many words are there in total?"
"This is simple, Chinese characters are commonly used. It's only two to three thousand words, is that much?" The girl still looked confused.
“Ask Qi Bo, is it too much?” Yang Shengli said, looking at Qi Bo with mocking eyes.
At this time, Qi Bo's face changed drastically. As a PhD student in computer science, why didn't he understand the mathematical knowledge contained in it?
