No. 284 Crushing Lee Sedol (6)

Nan Pojun glanced back at the host who was excitedly analyzing the fatal mistake of the 78th hand of Rotten Ke Go: "Their delusion? ”

Ji Susu did not have an air-to-air explanation for the strength of Rotco Go.

Ji Sujing lit up the LCD screen of the tablet computer wirelessly, and simply called up the backstage win rate of Rotten Ke Go. Ji Susu explained the strategy of the Rotten Ke Go team to the Nan Po Army with the most intuitive probability figures: "General, please look here. Before the 78th lot, Lee Sedol's win rate had been reduced to 11.9%; After the 78th move, Lee Sedol's winning rate suddenly increased to 42.2%, and it seemed that one of the gods turned the corner. But under our probability calculation method, a win rate of less than 50% is a loss. Whether the win rate is 11.9% or the win rate is 43.2%, as long as it is less than 50%, the result will definitely be Lee Sedol's loss. ”

Nan Pojun: "What if Rotten Ke Go makes a mistake again?" ”

Ji Susu explained: "So far, there has been no mistake in Ranco Go. Or, so to speak. Limited by computer hardware and our understanding of deep learning, there must be some flaws in Rotco Go that you and I don't know about. However, the chess power of Rotten Ke Go is strong enough to beat Lee Sedol in a variety of postures, even if Rotten Ke Go is flawed and has limits, it is not something that the current Lee Sedol can force out. Just Lee Sedol, he doesn't have the ability to push Rotten Go to the limit. ”

"The 78th hand, it's not a mistake either."

"Before the Rotten Ke Go Challenge, public opinion felt that Lee Sedol would win and Rotten Go would lose; It was only from the first game to the sixth game that the public opinion gradually admitted that the bumpy Go game was stronger than Lee Sedol. However, how strong is Rotten Ke Go, or how much stronger is it than Lee Sedol? Assuming that Lee Sedol is regarded as the criterion of chess strength, is the chess strength of Rotten Ke Go 1.1 Lee Sedol or 10.1 Lee Sedol? ”

"There are different opinions, and there is no consensus."

"Even many people think that Rotten Ke Go is only one line stronger than Lee Sedol, as long as Lee Sedol understands the mystery of human emotions for a while, he can awaken the power of Go and defeat Rotten Ke Go strongly; Or, as the webcast host optimistically imagined, he felt that Lee Sedol would be able to find the dead end of 'machines don't understand wisdom and machines don't know how to be flexible', and then defeat the bumpy Go with an absolute advantage. ”

"We want to shatter their illusions."

"We want to show the true strength of Ranco Go."

"In order to measure whether the chess strength of Rotten Ke Go is 1.1 Lee Sedol or 10.1 Lee Sedol, before this game, the Rotten Go team specially contacted Lee Sedol, hoping that Rotten Go would let the third son play the seventh game with Lee Sedol. It is a pity that Lee Sedol considered some outside factors, and he rejected the proposal of the Ranco Go team. ”

"Still, we wanted to test it out."

"Lee Sedol is unwilling to accept the handicap, so we will let Rotten Ke Go take the initiative to concede 9 moves."

"This is the truth of the so-called fatal mistake of the 78th hand of Rotten Ke Go."

Nan Pojun nodded.

In the first and fourth games, they won the official competition, and won Lee Sedol with the smallest wins and losses; In the second and third games, the mid-game battle was decided, and Lee Sedol, who was killed, threw himself early to admit defeat; The fifth and sixth games were decided in a decisive layout, and the miracle of dragon slaying was staged continuously; In the seventh game, the Spring and Autumn Search sought to "let the third son" defeat Lee Sedol. The seven games of the Rotten Ke Go Challenge, as speculated by the General Armament Department, each has its own goal, and everything is under the control of the Spring and Autumn Search.

The idea is good.

However, does Rotten Ke Go have the ability to make Lee Sedol 9 chess?

If it is overturned by Lee Sedol, the Spring and Autumn search will be self-defeating.

Nan Pojun had doubts in his heart but didn't say it, and sat quietly in the standard posture of a soldier and waited for the results of the seventh game.

In the live webcast projection, the host constantly connected with professional chess players to discuss and analyze the weaknesses of Rotten Ke Go, and laughed in a relaxed tone that the machine was not as flexible as the chess player after all; Outside the one-way glass, Lee Sedol may think of the proposal of the Rotten Ke Go team, which is as affectionate and serious as ever, without the slightest surprise of "one of the gods"; With the in-depth development of the chess game, the winning rate of the backstage of Rotten Go displayed on the LCD screen is rising bit by bit.

56.8%，

57.2%，

57.5%，

……

69.6%，

……

73.7%！

When the winning rate of Ranke Go rose to more than 70%, the host who had just praised Lee Sedol's hand and the professional chess player who connected the live webcast in real time unconsciously became less and less.

"Lee Sedol has finally won!" "Lee Sedol has finally discovered the weakness of Rotten Ke Go!" and other similar remarks have ceased to appear.

When approaching the official stage, the host helplessly showed a wry smile: "Rotten Ke Go is really Rotten Ke Go, and even the disadvantage of 9 goals can be recovered, which is so powerful that it is desperate." ”

The professional chess player who connected in real time also sighed: "Rotten Ke Go slowly accumulates small advantages, and quantitative changes cause qualitative changes, and now it completely overwhelms Lee Sedol." Rotten Ke Go has already shown its ability to be an official in the first and fourth games, and Lee Sedol can't win! ”

The host sighed: "It seems that Lee Sedol is going to lose again." ”

Professional chess player: "Playing against Lee Sedol, you can get back the disadvantage of 9 meshes, and Rotten Go is more powerful than I imagined." ”

The host smiled and said: "However, we humans don't have to be depressed, Rotten Go is not the god of Go after all." For example, the fatal mistake of the 78th hand of Rotten Go proves that there are still loopholes in Rotten Go. ”

The professional chess player looked cautious: "It's hard to say. Later, when Lee Sedol felt the pressure, he tried to repeat the miracle of his 77th move, hoping that Rotten Go would make a fatal mistake like the 78th hand again. But except for the 78th move, Ranco Go successfully bypassed the trap and perfectly coped with Lee Sedol's 'god hand'. Rotten Ke Go is simply like a saint seiya, the same trick, you can only use it once. ”

The host didn't take it seriously: "Rotten Ke Go is just a Go program, and it doesn't automatically write programs, how can it be as scoundrel as Saint Seiya." I think that this loophole is not a robbery loophole revealed on the surface, but a deeper loophole, Lee Sedol's 77th move only triggered the bug by mistake, which led to a fatal mistake in the 78th hand of Rotten Ke Go. We should dig deep into previous chess games and find the loopholes hidden in the depths. ”

Professional chess player: "If that's the case, it's easy. I'm more afraid that this is a strategy of the Spring and Autumn Search, just like the first six games to show the perfection of Rotten Go from all aspects, and the intention of this game may be to test the counterattack ability of Rotten Go in the case of 9 disadvantages. ”

The host didn't believe the suspicions of professional chess players: "If the Spring and Autumn Search is deliberate, Rotten Go is really too desperate." ”

The intuition of a professional chess player, guessed correctly.

However, the truth is far more terrifying than he imagined.

Nan Pojun looked directly at the helpless and complicated expressions of professional chess players, and once again lamented the rapid development of science and technology: "Artificial intelligence has conquered Go, how far is it from artificial intelligence to conquer the battlefield?" ”

As a result, as Ji Susu said.

The seventh game of the Ranke Go Challenge was as solid as the backstage win rate suggested, and it easily defeated Lee Sedol in the official stage and won by as many as 5 mesheks.

In the seventh game, Lee Sedol lost again.

0:7, in this Rotten Ke Go Challenge, the world's No. 1 chess player Lee Sedol was defeated.

From May 18th to June 5th, in just half a month, Ranco Go shattered the myth of the invincibility of Go.

Due to the lack of deep learning theory to continue to ferment for time, because the birth of Rotten Go can beat Lee Sedol in a variety of postures, the impact of Rotten Go on the world is far greater than the birth of Google AlphaGo in 30 years of memory. The market capitalization of Spring and Autumn Search soared from $69.39 billion on March 9 to $115.9 billion on June 4, which is enough to explain the problem.

Of course, Rotten Go is not the only reason why the market value of Spring and Autumn Search has skyrocketed.

After the financial crisis in 2008, China's economy flourished, and the scenery was unique; The troika of the real economy such as Zhiyu, Zhixing, and Zhuwei is advancing rapidly, and the smartphone business is in full swing; Compared with the first quarter of 2009, Spring and Autumn Search increased by 42.3% in the first quarter of 2010...... Wait a minute. After stepping into 2010, the Spring and Autumn Search continued to come with good news, even without the stimulation of Rotten Ke Go, the market value of the Spring and Autumn Search could steadily increase.

Of course, the hype of Rotten Ke Go is the most eye-catching after all.

Rotten Ke Go allows the world to reposition the Spring and Autumn Group.

Since then, Spring and Autumn Search has officially become the world's first-class enterprise.

The three giants of China's Internet companies, CAT, and Chunqiu's C are ahead of Alibaba's A and Tencent's T.

Secretly glancing at Nan Pojun, Wei Dongsheng felt that it was best to strike while the iron was hot at this moment to further deepen the impression of the Spring and Autumn Search for the world's first-class enterprises. The stronger the brand effect of Spring and Autumn Search, the smoother the cooperation between Spring and Autumn and the military will be, and the less hindrance it will be in the future. Thinking of this, Wei Dongsheng decisively took away the task originally given to Ji Susu: "The phased summary of the Rotten Ke Go Challenge will be given by me." ”

Ji Susu was at a loss and didn't understand Wei Dongsheng's thoughts.

Considering the presence of Nan Pojun, Ji Susu did not ask Wei Dongsheng why: "Do you need my cooperation for anything?" ”

Wei Dongsheng smiled: "It's just an impromptu speech." ”

After that, Wei Dongsheng said goodbye to Nan Pojun: "General Nan, let me be busy for a while." ”

Nan Pojun smiled and nodded with an empathetic smile: "Go get busy." ”

Wei Dongsheng took over Ji Susu's relevant equipment and made a detour to the scene of the Ranke Go Challenge.

As mentioned earlier, with the addition of various scientific and technological achievements and legendary honors, Wei Dongsheng's popularity is extremely high.

Wei Dongsheng is not an entertainment star, but he has a higher reputation than an entertainment star. Regardless of whether he agrees with or disagrees with the concept of the Spring and Autumn Period, Wei Dongsheng has broken through the gap between age and class and walked into everyone's field of vision. At this time, Wei Dongsheng was a celebrity of the times in the country and even the world. Seeing Wei Dongsheng's figure, the audience before they could understand why Wei Dongsheng suddenly appeared, they subconsciously applauded and welcomed.
