1991 Starting from the core

As a female programmer who once worked in Pandora Labs, Ye Rudai quickly understood what Su Yuanshan and Xi Xiaoding were communicating.

Even at the beginning, she really wanted to join the deep learning group, not to mention what contribution she would make, but just to understand the thinking of those big guys.

But later when she tried to get involved, she decisively realized that she was not the material.

Mastering algorithms is actually not difficult. As long as you learn high school mathematics and advanced mathematics well, and master the algorithm course compiled by Xi Xiaoding, it will basically not be difficult.

But summarizing and creating algorithms, especially machine learning, is not something she can get involved in at the moment - that is the world of math giants.

Is Pandora's chess program complete?

Well, it's done. Su Yuanshan hung up the phone and said happily: You know that the chess program developed by Mr. Xi and his friends is different from ordinary ones, right?

Well! That's the difference between artificial intelligence and artificial retardation. Ye Rudai pursed her lips and smiled, and immediately added: These are Mr. Xi's exact words.

Haha! Mr. Xi said it well! By the way, do you want to go see it tomorrow?

Uh... forget it, I have class tomorrow and I have to analyze the data.

…

The two broke up downstairs in the dormitory. Su Yuanshan returned home and told his father the news. Professor Su Xinghe was also very happy - but Su Yuanshan felt that his father obviously had not realized what it meant.

Dad, don't you know how to build a supercomputer? Help Yuanxin build one too. Su Yuanshan sat on the sofa and smiled at his father: Build one just for playing chess.

Are you here specifically to play chess?

Yeah... Su Yuanshan nodded: The current supercomputer in school is fast in integer operations, but floating point operations are a bit bad. According to tests, it can only calculate 30 million steps per second.

Thirty million steps are still too few? Su Xinghe laughed and said, Do you know what it means to be incompetent?

Su Yuanshan pursed his lips.

He remembered clearly that although Deep Blue had less than 500 low-frequency chips at the time, they were specially manufactured for chess, and the computing speed could reach 200 million steps per second!

You know, this kind of deep learning mainly uses single-precision floating point computing capabilities. Now the supercomputer of Electronic Science and Technology has more political attributes in a sense. Although it is fast, it is only fast in integer arithmetic.

In actual applications, floating point operations are the most demanding test of computing power.

Thirty million moves is a long way off... You have to know that there are almost two million chess games circulating in the world. It is really a big project to input them all and then learn them.

Seeing that his son didn't look like he was joking, Su Xinghe became serious and asked, Do you really want to build a supercomputer specifically for playing chess?

You don't think I'm joking, do you? Su Yuanshan smiled: Dad, it seems that you have fallen behind in the field of algorithms... In the future, neural networks, deep learning, and artificial intelligence, the easiest way to start is by playing chess.

Su Xinghe thoughtfully nodded and said, What you say makes sense, but supercomputing is really not something I can just build. If we really want to build it, we have to adopt a cooperative research and development model.

Well, okay, let's stop talking about this first. When our CPU comes out, we will gather the team again!

Haha, okay. I'll give you a shout when the time comes.

…

In the afternoon of the next day, Su Yuanshan went to the supercomputing center.

Although chess has become an international game, there are still competitions in China, but it is not as famous as Chinese chess. This is also one of the phenomena of internationalization in China.

Even because it is chess, chess has added additional noble BUFF in some places and among certain groups of people.

Gu Xiaochun is the domestic chess champion and has been among the top five players in international competitions.

Therefore, this competition is purely a friendly invitation and has the meaning of testing, so Yuanxin did not make a big move. Gu Xiaochun also kept a low profile because he had the mentality of win without force and because Yuan Xin gave him money.

That's right, Gu Xiaochun knew that he would win without force even before he made the move.

Nowadays, with the development of computers, there are Chinese chess games and international chess games. He is aware of them, and has even played them on the Little Overlord learning machine at home - it is really weak, and he also specializes in sharpening chess weights.

In Gu Xiaochun's mind, even if the supercomputer known as Asia's number one was moved here, it would just go faster.

Hello, Teacher Gu. Su Yuanshan did not introduce himself, but simply said hello.

Hello. Gu Xiaochun, who was in his early thirties, was sitting on a chair, staring at the chessboard to relax. When Su Yuanshan greeted him, he didn't take it seriously and replied with a smile.

Teacher Gu, I'm not very good at chess, but I heard that... chess players can usually calculate to ten moves, isn't that true? Su Yuanshan pulled up a chair and sat next to Xi Xiaoding, smiling. asked.

Uh... Gu Xiaochun was startled for a moment, then laughed and said, Who told you?

Uh... isn't it?

Anyone who can calculate ten moves is a master. Many people can't even calculate eight moves. Gu Xiaochun said with a smile: And whether it's chess, chess or even Go, these are purely intellectual games... There are a lot of variables.”

Su Yuanshan and Xi Xiaoding looked at each other, and they both smiled at the same time.

The implication of Gu Xiaochun's words is that this computer is nothing more than a lump of iron. You may say that it is fast at addition, subtraction, multiplication and division, but when it comes to simulating intellectual games such as the ever-changing chessboard, it is still a little behind.

After all, intelligence is exclusive to humans.

Su Yuanshan touched Xi Xiaoding: Senior brother, have you ever had sex with Teacher Gu?

I've done it once, but I can't do it. Xi Xiaoding shook his head frankly.

Although Gu Xiaochun didn't know Su Yuanshan, he knew that Xi Xiaoding was the chief scientist of Yuanxin and a professor in the Department of Electrical Engineering. He was a real talent, and a genius... He also said very humbly at the moment: Professor Xi is humble. He has specialization in the field. , I just mastered a little more skills and played tens of thousands more games.

Gu Xiaochun said with a smile: If Professor Xi can sit down and play tens of thousands of games, he will definitely be much better than me.

Tens of thousands of rounds... Su Yuanshan repeated leisurely, and then asked Xi Xiaoding: Brother, how many AI skills have you learned?

Xi Xiaoding looked at Gu Xiaochun and said in an understatement: Time is limited, so I probably learned about 200,000 games!

Two hundred thousand games!

Gu Xiaochun's expression changed!

The whole person stood up!

impossible!
