In the 18th round of the siege, Li Xiangping, who had just won the "Fujitsu Cup", missed in this place, and he was defeated by Lee Sedol with a classic skill.

Of course, chess fans know that "one son solves two signs" belongs to the kind of very cool tesuji, once the move is basically unsolvable, so when Li Xiangping saw that chess, it took two minutes to figure out that it was indeed unsolvable, and he was very happy to admit defeat.

After the game, the two players did not have a long review, after all, the language is not understood, and it is impossible to have a full-time interpreter for the review of the game, so after a few random strokes, Xiao Li dodged and left, leaving Li Xiangping alone in the same place thoughtfully.

And he was in a daze, and more than ten minutes passed.

No one thought there was anything wrong with it, and no one bothered him.

After all, this is Li Xiangping, after all, this is one of his only two defeats this year, and it is his second defeat this year after losing to Gu Dali in March.

Since he suffered a defeat, even if it is Li Xiangping, he definitely needs to adjust his mood, and considering that it is rare for him to encounter this situation now, then he takes a little longer to tidy up his hairstyle, which of course everyone can understand.

It's just that no one knows that Li Xiangping's "hairstyle" this time is so special:

"Alas...... Xiangping Xiaoyou, I didn't know until now that if we want to defeat the machine, it turns out that this person will be the biggest help. ”

Lao Shi's words seemed inexplicable, but Li Xiangping immediately understood, not only did he understand, but this was also a new understanding he had after he played today's game of chess:

"Hehe, Brother Ding'an, do you think the same way, it seems that the hero really sees the same thing......."

To clarify Li Xiangping's new understanding, we must first briefly understand the basic context of this game of chess:

From the very beginning of this game of chess, the two practiced a "dog move".

Well, a dog move that has almost become a "dog formula" and is almost familiar to everyone in today's professional chess world. And not long ago, Xiao Li also used this change, that is, in the round of 16 of this year's "Toyota Cup", he was eliminated by Kong Erjie.

However, Xiao Li is Xiao Li after all, he still uses the changes he has lost, and "not taking the usual path" seems to be his pursuit forever, and today he is no exception, when he made more than 40 moves in the overall game, he changed his moves again, so that the "dog formula" deviated from the normal track.

It's just that Xiao Li's change of tactics this time is different from last time.

The last time he changed his moves, not only did he not take advantage of Kong Erjie, but he was even found by Li Xiangping in the research room, and the good move he found in a short period of time was a good move that could immediately defeat that move.

Therefore, his last change of tricks, objectively speaking, did not have much technical content, and it was very similar to reluctantly "taking the unusual road" in order to "take the unusual road".

But his change of tactics today is different, completely different!

This move not only has stronger concealment and confusion, but also has a much higher technical content, so high that even Li Xiangping was lost, so high that he was defeated by others in less than 100 moves.

Li Xiangping now looks back at this game, and he does not think that he lost unjustly-------

In fact, when he first saw Xiao Li's change of moves, Li Xiangping also counted two changes, and the changes along the way were slightly peaceful, and if he continued to evolve according to the changes in that way, he might still gain a little profit.

And the other way of change, of course, is the point of no return in actual combat.

The reason why he chose this road of no return in actual combat is because he did not calculate that step of "one son solves two signs", that move is the 93rd hand of the overall game, and Li Xiangping's calculation of the road just stays at the 92nd hand of the whole world.

Further in-depth discussion: It is normal for Li Xiangping's calculation to stay there.

Because this is the characteristic of the classic trick of "one son solves two signs": as long as you don't calculate this step, then in the previous hand, you must think that you are in favor, and the person who collapses immediately should be the opponent--------

And this is precisely Li Xiangping's game psychology at that time: Do you dare to change your blatant dog moves? You're too unreasonable, aren't you? Aren't you looking for death? So how am I going to punish you? ...... By the way, it should be the right solution to evolve like this, if I go like this, then Xiao Li seems to be about to collapse within a hundred hands......

It is precisely because of such a game psychology that Li Xiangping's calculation is stuck at 92 hands.

It is precisely because Li Xiangping has such an awareness that he thinks that he has nothing to say about losing today, so he will very much agree with his plug-in statement: An opponent like Xiao Li is really very rare, especially if he wants to challenge the dog, then such an opponent is even more valuable! It is much more difficult than an opponent like Da Li Gu Dali.

Why? To use an inappropriate analogy, if you compare the dog tricks you are studying now to "Xuanmen Zhengzong", Da Li is also studying "Xuanmen Zhengzong", Gu Dali is also studying "Xuanmen Zhengzong", and there are many, many other chess players who are also studying "Xuanmen Zhengzong" now.

However, Xiao Li is different, he is still studying his "Evil Sect Outer Dao", and judging from today's game of chess, his "Evil Sect Outer Dao" seems to be also upgrading, at least much stronger than him in his previous life.

In his previous life, Xiao Li actually created the "zombie flow" within the framework of human Go theory, but now, his evil kung fu is already based on "dog moves-------

Li Xiangping didn't know what to choose, but he could confirm one thing: Xiao Li's current "Evil Sect Outer Dao" is already a level stronger than the "Zombie Stream" in his previous life.

So now the question comes: if Li Xiangping stands in the perspective of sharpening his chess skills, it is more helpful for Li Gudali's "Xuanmen authenticity"? Or is it more helpful for Xiao Li to be an escalated "evil way"?

The answer is obvious, everyone knows that Xiao Li's style must be more helpful!

"Alas, Xiao Li is really Xiao Li, the unruly Xiao Li, the always maverick Xiao Li, with the existence of an opponent like him, Brother Ding'an, do you think this is a great joy in life? It's a pity that there are still too few opponents like him. ”

"Hehe, this Xiangping little friend is reassured, I believe that in the near future, there will be more and more such opponents."

"Oh, why did Brother Ding'an say that?"

"Xiangping Xiaoyou, I remember that in a game a few months ago, you said to your little brother: Those who learn from me live, and those who are like me die, since you understand this truth, are you still worried that others don't understand?"

Li Xiangping had a black face at that time: "How can Brother Ding'an speak, what do you mean since I understand ......"

However, although Li Xiangping has a black face, he thinks about it, there are so many smart people in the world, especially in the professional Go world, all of them are highly intelligent.

So if you want to challenge yourself or even defeat yourself, it is impossible for everyone to follow behind them, and when they understand the dog tricks to a certain extent, someone will definitely find a way to find another way, so as to slowly become an "evil outsider" like Xiao Li.

It's almost a given!

Because he is not a real dog after all, he can't do it like a dog to "reduce the dimensionality" of humans, and make humans kneel down and sing about conquest.

Since this is the case, there must be many people who want to defeat themselves, especially those chess players in the first group army of professional chess------- Li Xiangping is now a professional chess player himself, and he doesn't believe it at all if others don't think so.

“....... Hehe, good, it's a good thing, now it seems that the "Demon Gate" in the Go world may really be able to carry forward, but then again, the "Demon Gate" that is qualified to enter the Go world, there is really no idle generation, and even from a certain point of view, the average qualification of the "Demon Gate" in the Go world is actually far more than the average qualification of the "Xuanmen Authentic", and now I just don't know which chess players will enter the Demon Gate in the next 10 years.......

Just when Li Xiangping was thinking like this, Lao Shi Leng didn't know a question that made his heart beat faster.

"Little friend Xiangping, I suddenly thought of a question just now, and I really want to ask your opinion."

"If you have something to say, why should you be so serious."

"I was just thinking, if it were the same machine today, would they be able to avoid this step of "one son solves two signs"? ”

"Ah?!!!! This ......."

Hearing Lao Shi's question, it was like a thunderclap, which instantly made Li Xiangping's heart beat faster, and after he forcibly calmed himself down and thought for a while, he asked rhetorically:

"What does Brother Ding'an think?"

Lao Shi smiled bitterly: "I just can't be sure, so I want to listen to the opinions of Xiangping Xiaoyou." ”

At this time, Li Xiangping had completely calmed down, and he smiled: "I think the dog is likely to be unable to avoid it." ”

"Why?"

"Without him, because of a method similar to "one son solves two signs", the previous evolution must be extremely fierce, frightening step by step, and the trick does not leave the back of the head, and this characteristic is precisely where the weakness of the dog lies. ”

Lao Shi also thought about it a little: "What does Xiangping Xiaoyou mean, every chess hand before this, the winning rate is shaking violently, and it is likely that there will be blind spots that the machine can't find?" ”

Li Xiangping continued to smile: "That's right, that's what I mean, although I'm not sure now, the dog will definitely not be able to avoid the "one son to solve the two signs", but the weakness of the dog must be hidden in similar means, great Li Sedol!" I can now finally understand why he was able to defeat a generation of dogs in the first place. ”

"The first generation of dogs has this weakness, but what about the second generation of dogs and the third generation of dogs?"

"Haha Ding'an, don't worry, this weakness is not only the first generation of dogs, but also the second and even third generations of dogs, anyway, before you and I cross, human beings have not solved this problem for the time being."

When Li Xiangping replied to Lao Shi's question, he recalled several things in real history, and these things may be able to eliminate the blind worship of Go AI by some chess players.

After the birth of the alpha dog, especially after Google published an algorithm paper, everyone saw that foreign dogs of all sizes quickly emerged from all over the world, and in the previous life, Li Xiangping knew several core members of the "Star Array" research and development team of the earth dog, and there were two friends who were still on good terms.

According to their introduction, their research and development of the "Star Array" is actually based on the open source paper, and then their team decomposes it into about 80 specific topics, and after these 80 topics are tackled, the "Star Array" comes out.

In fact, it is not only them, but the other teams are in a similar situation, using that open source paper as a foundation, and then breaking it down into specific topics.

It's just that because of the different ways of decomposition, we can see that the big and small foreign dogs seem to have different "chess styles".

However, what interested Li Xiangping was not the chess style, what he was interested in was that after the team developed the "Star Array", they took on a new task, that is, to develop an intelligent traffic light system for a city in the Yangtze River Delta.

According to their own words, the development of an intelligent traffic light system is much more difficult than the "Star Array", which only needs to tackle 80 topics, but the traffic light system has about 130.

Eventually, that traffic light system was developed and is already running in that city.

Most of the time, the system worked well, saving manpower and making traffic flow better throughout the city.

However, during the trial operation, the system also had two problems, and there was a command disorder, which led to a large traffic jam in the whole city.

What's the problem? There was an extreme situation, when the city had a heavy rainstorm before the end of work, causing many vehicles to be stuck on the road, and when the number of cars increased and the limit of the system was exceeded, it became disordered.

If you look back at Go, there are extreme situations on the chessboard, and dogs are also prone to disorder.

Isn't the two similar?

And the root of all this is actually the basic algorithm, as long as the algorithm is not corrected, then this problem cannot be solved.

Li Xiangping later asked his friend: What level is your traffic light system?

My friend smiled, and he said that if it is replaced by Go AI, it will be no problem to beat the second generation of dogs, as for the third generation of dogs, considering that Google has developed the "ancestor of dogs" after all, then they are still polite, thinking that it is slightly worse than the third generation of dogs.

However, my friend added that if it was replaced by the strongest Go AI "mastery" in China at that time, it should be on par with the three generations of dogs "Alpha Yuan", if the two want to really compete, it is to see the competition of hardware, who has stronger hardware and wins.

To tell the truth, when Li Xiangping first heard this, he was still very surprised as a layman, maybe it was also because of the "Dog Ancestor", he, like most chess fans, subconsciously thought that "Ah Fa Yuan" was stronger.

So Li Xiangping continued to ask, wondering what the professionals who developed AI thought.

The friend told Li Xiangping: Considering that Alpha Yuan was so shocking and only appeared once in a hurry and then retired from the rivers and lakes, so if it is excluded that Google hid more advanced algorithms for commercial reasons, then only from the public appearance of the dogs, they and "Jueyi" are indeed on the same level.

Li Xiangping asked at the time: "Then what do you mean, in fact, the three generations of dogs have not made up for this flaw?" ”

There was no hesitation in my friend's answer, and his answer was categorical:

"No, as I just said, excluding the fact that Google hides more advanced algorithms, this flaw definitely exists, because such a vulnerability cannot be made up for by simple patching."

Li Xiangping continued to ask: "Then do you think Google doesn't have more advanced algorithms?" ”

The friend smiled and said that he couldn't say anything about this, but he personally thought it should not be.

Li Xiangping asked again why.

That friend told Li Xiangping that in fact, since the Google paper came out, scientists all over the world have actually discovered that flaw through practice and want to find a solution.

However, it is a pity that algorithms are the most basic basic disciplines, but it is this most basic thing that is the most difficult to solve, so until now, there has been no better algorithm.

The only one who is leading is Google, and they have a team that has come up with an idea, which seems to be the most reliable of all ideas, but at the time, it was just an idea, they hadn't built a model yet, so it wasn't a mature algorithm.

Next, that friend was enthusiastic to introduce Google's new ideas to Li Xiangping.

Obviously, Li Xiangping's friend is also the kind of nerdy science and engineering man, he told Li Xiangping that, it was completely playing the piano to the cow, where could Li Xiangping understand that.

I only know that there are real numbers and imaginary numbers, and there are positive matter and antimatter.

Google seems to want to use similar ideas to make up for that flaw, which sounds so profound.

At that time, the only thing that impressed Li Xiangping was to listen to the friend's introduction: the core members of the team that Google proposed this idea are also three Chinese, two from Tsinghua University and one graduate of the research laboratory of the Chinese Academy of Sciences.

This made Li Xiangping not know what it was like at the time.

When he thought of this, Li Xiangping didn't want to continue to recall:

"Hehe, Brother Ding'an, let's discuss this issue later, today's game is not over yet, let's go and see the situation of other teammates."
