At around 6 p.m., when Li Xiangping rushed home, he didn't even bother to eat. He turned on his computer as soon as possible and studied and reviewed today's game with the help of domestically produced "unique skills".

After finishing the review, Li Xiangping once again fell into a state of being unable to let go.

Because for today's game of chess, the winning rate change curve displayed by "Jue Yi" is very simple. Before 138 moves, "Jue Yi" believed that it was leading all the way, while Google's "Afa Yuan"'s winning rate was from about 48% all the way.

dropped to more than 30 percent.

Then because of that move, my winning rate plummeted, from over 60% to about 45%, and then continued to decline steadily until it was less than 5% in the final game.

The subsequent winning rate curve changes steadily, which proves that my officials have also performed at a high level. As for the winning rate continuing to decline, there is nothing that can be done --------

It’s also half an eye away, but if you are half an eye away when the overall situation is 100 hands and half an eye away when the overall situation is 200 hands, the dog will definitely show different winning rates. The former may still be around 50%, while the latter will basically drop to 100%.

Less than 20 points.

After completing this work, Li Xiangping continued to use AI to dismantle the chess game. He hypothesized that if he had not made the fatal "block" move, but as Lao Shi said in the game, if he had "posted" the first move,

What will be the final result?

"Jue Yi" believes that "posting" is the right answer at the moment!

At that time, white only had to make this inconspicuous exchange, and black would no longer have the official trick of taking chestnuts out of the fire.

And as long as he can guard against the tactics used by dogs in actual combat, "Jue Yi" believes that he can still maintain an advantage of about one and a half eyes.

After he understood all this, Li Xiangping was even more speechless. Such an advantageous situation allowed the dog to reverse in this way, which really hurt Li Xiangping.

Yaya gently walked into the study and pressed Li Xiangping's temples with both hands:

"Xiangping, let's go eat. You only ate a few pastries at noon. I'll make them for you in the evening..."

Li Xiangping turned around and smiled reluctantly at his girlfriend: "I don't have an appetite. Okay, you can eat it yourself first. Let me stay in the study for a while."

After Yaya went out, Li Xiangping continued to be in a daze, but his current state was such that even Lao Shi could not stand it anymore. A few minutes later, Lao Shi suddenly said:

"Little friend Xiangping, I don't think you need to be like this. Although it is a pity to lose this game, but as you said in the afternoon, this game has made you and I gain confidence. Before this, we have always imagined dogs too much.

It's scary. Even though we have been using various ways to cheer ourselves up, you and I actually know it very well. This is a sign of being unsure of ourselves. We both feel that there is little chance of winning this game. But after today's game, I

I don’t know what you are thinking in your heart, but I am much more practical, at least on a technical level, as long as you and I join hands, I am not afraid of this dog at all, do you think so or not?”

silence!

Faced with such a long speech, Li Xiangping seemed not to have heard it. He continued to stare at the chessboard in front of him in a daze.

Lao Shi didn't know how to persuade him, so he had no choice but to say:

"Alas~ Today's game is really a pity. You and I both ignored such a simple pass. It's a pity that the seconds were already counting. It would have been better if it had taken a little longer..."

"Brother Ding'an,"

At this time, Li Xiangping suddenly said:

"By the way, I forgot to tell you before. In fact, when I was discussing the conditions of the competition with the Google team, Dr. Huang from Google once gave me a suggestion. He sent me an email and told me that if this dog plays a game of chess, it must be

It couldn't take three hours, so he made a suggestion at that time, it was also three hours, the dog would use one hour, and we would be given two hours, so we could play this five-game chess game in this way."

"oh?"

Li Xiangping continued: "Do you know why I didn't tell you? Because I rejected Dr. Huang's kindness at the time."

Lao Shi praised: "The little boy from Xiangping did a great job. As a competitive sport, the most important thing about Go is fairness. It is also one of the sources of charm of all competitive events. If it were me, I would not agree with this."

Unequal conditions.”

"Yes, for the sake of fairness, and also for the sake of being able to defeat the dog openly and squarely under completely equal conditions. Alas~~"

Li Xiangping sighed and continued: "Maybe dogs never make mistakes, which is a huge advantage that cannot be compared. Take today's game as an example. Brother Ding'an, you have to admit that even if we make a mistake,

This basically represents our highest level, because from a probability perspective, or from a philosophical perspective, it is absolute for humans to make mistakes, and not making any mistakes is only relative. We only made one mistake today. From a probability perspective, this is already

It’s a small probability event, but we still lose to the dog in the small probability event, so I just thought, this won’t work. If we want to really defeat the dog, we not only cannot be worse than it technically, but we may also have to think

Find another way."

Hearing this, Lao Shi was relieved: "Haha, little friend Xiangping, it turns out that you were thinking about this problem just now, but you made me worry in vain. So tell me, have you thought of any solution?"

Li Xiangping said straightforwardly: "The best way is, of course, to find a way to make the dog make mistakes."

"this……."

Li Xiangping continued to say to his plug-in: "Brother Ding'an, in fact, we have discussed before that the machine has its boundaries when faced with the complexity of the problem. Once it exceeds its boundaries, it will inevitably have program disorder. In fact, for

We don’t have to doubt this, because this computer science originated in the West. The founder of this science is named Turing. This man is known as the father of artificial intelligence. He invented a Turing machine and laid the foundation for this science.

The theoretical basis is actually the source of all current AI. This Western expert said back then that the "mechanical complexity" of the universal Turing machine has a critical limit when calculating. Beyond this limit, it will

It was solved by increasing the length and storage capacity of the program. The idea he proposed actually pioneered the computational complexity theory in computer science."

Li Xiangping paused and continued to say to the plug-in:

"I won't go into more details, because if I continue to expand, firstly, I can't explain clearly, and secondly, Brother Ding'an, you definitely won't understand either. In short, you just need to remember one thing. In fact, until now, this science is still

It has not broken through the theoretical framework established by this person. Since it is still within this framework, the dog must still have the flaw I just mentioned, which is the flaw at the critical point of complexity."

Lao Shi suddenly said: "But in those 400 dog fighting games, why didn't we find this problem?"

Li Xiangping smiled slightly:

"This is a very good question. In fact, it was just reading those 400 chess records in the past few months that made me ignore the dog's flaw. The reason why there is no such problem in the 400 games is very simple. The Western senior

Didn’t people say that to solve the problem of critical point of complexity, in the past, we have always relied on increasing the length and storage capacity of the program?

, and the first to third generation dogs are all developed by the same team, so they must all use the same hardware configuration when testing. Since the hardware configuration is the same, the critical points of the several machines must be basically the same, and their

Most of the competition is within the same critical point range, which naturally prevents us from seeing the problem.

"That, that..."

When it comes to such a topic, Lao Shina, as an ancient man, must be inferior to Li Xiangping, so he changed the subject and said:

"So, little friend Xiangping, have you figured out how to force the dog out of his trap?"

Li Xiangping smiled bitterly and said:

"How can we think about this well, because such a critical point only exists in theory, and we can't see it or touch it. Again, I have to thank South Korea's Lee Sedol. After all, he has given us so much in the last man-machine war.

It provides a vivid example, so in the second game tomorrow, of course we can’t

Completely imitating Xiao Li, but if possible, our game ideas can still be based in that direction. Haha, let’s not talk about it. If I continue to talk, I may have to get into trouble again. In short, everything is adaptable. I’m going to eat.

, the most important thing now is to recharge your batteries.”

After some mental construction, Li Xiangping actually had a good sleep that night, and then the next day, he continued to set off with high spirits, preparing to start the second game with the dog.

In the second game, it was Li Xiangping's turn to take charge of black. In order to save a little more time during the layout, he still used the "two consecutive stars" start that he used most in his career.

The dog also responds with "two consecutive stars", thus forming a "four-star battle" on the chessboard that is very common in the AI ​​era.

On the fifth move, Li Xiangping thought briefly for a minute, and he directly "point three three" in the upper left corner occupied by white.

It is worth mentioning that although this move was "initiated" by Li Xiangping, and because of his outstanding record, this move is more popular in the profession.

However, the popularity of this chess move is only supported by Li Xiangping's record. Not everyone agrees with this chess move.

In particular, veteran chess players such as Lao Nie have publicly stated that they do not like this move, believing that it violates the chess principle of "the sooner a strong momentum is formed, the more advantageous it will be."

Only now that AI has appeared, everyone has discovered that the dog seems to agree with this chess move, which leaves everyone speechless. Of course Lao Nie also came to the scene today.

Not only did he come to the scene, but less than 10 minutes into the game and less than 10 moves on the chessboard, he was already shouting in the viewing room:

"Ha! Xiao Li Fei Dao, everyone, look, this dog actually used Xiangping's first Xiao Li Fei Dao to deal with Li Xiangping. I watched a good show today. Since the dog can do it here, it seems that it is also very good.

I agree with this method, but this flying knife is Xiangping's original creation. So is it the fake Li Gui who beats the real Li Kui, or is the real Li Kui teaching the fake Li Gui a lesson? Today I want to take a closer look."

Well, the "Xiao Li's flying knife" that Lao Nie mentioned is actually the Mi family's flying knife in real history.

Obviously, since this fixed formula appeared 16 years in advance, it is naturally impossible for the surname to be Mi. Now it is Li.

And because this technique first appeared, it was in the distant 2000. In the semi-finals of the "Samsung Cup" that year, Li Xiangping used this flying knife to defeat the then Korean King Liu Changhyuk 9th Dan in one fell swoop.

.

Li Xiangping used this formula as a flying knife at that time.

In addition, the changes in this formula are indeed very complex, and it does have the attributes of many "flying knives" in Go.

So over time, until now, this formula seems to have a more popular name: Xiao Li Feidao.

In the game room, when Li Xiangping himself saw this move, he slowed down his move slightly.

Because although he ordered point three and three, the choice to make this change actually lies with the dog. So he really didn't think about it before, in a game like today, this "Xiao Li Flying Knife"
Chapter completed!
