Go Legend

   Chapter 337 Dog's Weakness

Due to the influence of the previous "SARS", the schedule of this "Celebrity Battle" was very compact, with 5 sets in 7 days, and the challenger was decided within a week, only between the 2nd and 3rd, and the 4th There is a rest day between round and round 5.

To be honest, such an intensive schedule is a great test for physical strength. Although in later generations, due to the influence of Korean Go, such a schedule seems to have become the norm. However, don’t forget that most of the games in later generations are 2 hours at most. 2 and a half hours, but the current game is 3 hours of slow chess per side. In comparison, of course, the current game is much more tiring, and it is obviously not good for the "old comrades".

   "Teacher Cao, I've accepted it."

Li Xiangping's opponent in the first round will encounter an old comrade, who is one of China's "Five Tiger Generals" in the era of the Sino-Japanese Go arena, commonly known as the "Cao" in "Nie Ma Cao Liujiang" , Shencheng chess player Cao Dayuan 9 dan.

   Cao Dayuan is a very early 9-dan player in China. If you really want to count it, he should be the 5th 9-dan player in New China. When he rose to 9-dan, he was only ranked after Chen, Wu, and later Nie and Ma in ancient times.

   For Cao Jiuduan, because his achievements are not particularly outstanding, Li Xiangping does not remember what championship he has won, but an anecdote of his that year impressed Li Xiangping deeply.

One year, Cao Jiuduan went to participate in the Sino-Japanese Go arena. Li Xiangping has already forgotten which session, and who his opponent is Li Xiangping. one of these.

Li Xiangping only remembered that the game was held in Yangcheng, and at that time, professional chess players were still allowed to smoke in the arena, and Cao Jiudan would also smoke, so before playing, he specially asked the staff to prepare a box for him Cigarettes, and specify the brand "Double Happiness".

Well, Cao Jiuduan's request is of course not excessive, because even in those days, "Double Happiness" was not a high-end cigarette. This brand was very common, and there were several kinds, not only in Shencheng, but also in Yangcheng. Produce a kind of "Nanyang Double Happiness".

  However, it was such a coincidence that when the staff member went to buy cigarettes for Cao Jiuduan, not only did he not find "Shencheng Double Happiness", but even "Nanyang Double Happiness" was just sold out.

   Seeing that the game time was coming, the staff felt that Cao Jiuduan could not be delayed to play chess. After all, this ring match was a major event that the people of the whole country were paying attention to, so in a hurry, the staff gave Cao Jiuduan a box of "three-five".

   He didn't want to wait for Cao Jiuduan to see this box of "Three-Five", his face changed greatly, and he even became uneasy because of it, and Cao Jiuduan also lost the chess game in the end.

   Not because of anything else, but because the Chinese team temporarily trailed 3-4 before Cao Jiuduan came on stage.

   This is the reason why Cao Jiuduan has to name "Double Happiness". Think about it, how good this brand is. Not only is it festive and auspicious, but it can also get a lottery, indicating that the score will be tied 4 to 4.

   However, the staff member had to take out a pack of "Three Fives" at that time.

   Of course, this anecdote cannot explain other issues. Li Xiangping believes that it has confirmed two things:

First, in that era, the Sino-Japanese Go arena was indeed the most influential Go event. You can see that even a box of cigarettes could be made into a joke by the people at that time, and let Li Xiangping this age. everyone knows.

Second, as Go is a mental game, most professional chess players are very "superstitious", at least such things as "psychological cues" are common in the professional chess world and will have a great impact on the game. .

   Of course, when it comes to the current Cao Jiuduan, of course he will no longer be so obsessed with winning or losing. Facing Li Xiangping's "acceptance", the honest and honest Cao Jiuduan smiled gently:

"What did Xiangping say, how can I be qualified to give you, huh, don't say it is now, even if I am the most peak of course, then you have to give it up, Xiangping, you are on the "world" I have carefully read the serialized articles of my book, and I am suddenly enlightened, some questions that I have not understood for decades, I feel that after reading your article, I suddenly become enlightened."

  Li Xiangping smiled modestly. It is now October, so his "I want to do this" series has been serialized in the magazine for several issues. Li Xiangping is not at all surprised that Cao Jiuduan would be interested in this series of articles.

After all, at that time, Cao Jiuduan was well-known in the chess world for his clear chess logic. This is also a particularly "reasonable" player in chess, and his "I want to play like this" series is actually to reveal the "dog move". The chess theory is the main thing. In this case, Cao Jiuduan will of course be very interested in this kind of article.

It is also a very strange thing to say. Before the "Alpha Dog" was born, everyone always thought that even if the machine could surpass humans in the future, the strength of the machine should still be on the specific calculation road, in the "chess theory". As for a relatively imaginary field, then humans should still have certain advantages.

However, after the dogs really appeared, everyone found that it was not the case at all. The difference between man and machine in the specific calculation of the path was not too big, but the layout, chess theory, these relatively empty places in Go, Go AI has thrown away several streets of human beings, and the gap between human and machine is mainly concentrated in this place.”

It must be noted that Li Xiangping’s words are really not nonsense. Everyone knows that in later generations, the Go national teams of China, Japan and South Korea will all be equipped with Go AI as a tool, and use dogs to train and learn. However, the national players of the Three Kingdoms have found that as long as specific calculations are involved, especially if there is a "kill", the dog's performance is often unreliable.

And it's not that only one dog is unreliable, not only is the "excellent art" used by the Chinese national team unreliable, the "lira" used by the Koreans is also unreliable, the Chinese "star array" is unreliable, and the dogs used by the Japanese are unreliable. Dogs are also unreliable. It seems that except for "Afa Yuan" who has been "seal", there is no dog that is more reliable in the field of "killing".

  The national players of the Three Kingdoms have found that once this situation occurs, dogs often make mistakes, but human players can find the best solution for the whole situation.

   Is this kind of thing a bit abnormal? Seems hard to understand?

   Well, although Li Xiangping is not a computer expert, he thinks it is not difficult to understand. Everyone knows that once there is a duel kill in Go, especially the relatively large-scale duel, it is of course a more extreme situation. The so-called one-step king, one-step death, the winning side has a winning rate of more than 99%, and the duel-kill The losing side may have a winning percentage of only a few tenths of a percent.

That's right, it is precisely because of the violent shaking of the winning rate that this is the main reason for the dogs to make mistakes. After all, all dogs are an algorithm based on the winning rate. It is of course difficult for ordinary winning rate fluctuations. Falling dogs, such as suddenly changing from 30 percent to 70 percent, is normal for dogs.

   However, the previous step is still fifty percent, and the next step is either ninety-nine percent or zero percent?

   It is precisely because of this extreme choice that dogs often make mistakes.

   There is no doubt that this should be a weakness of dogs.

   At least before Li Xiangping crossed, there was still a weakness in Go AI.

   However, such a weakness does not exist for humans.

   In addition, this kind of "counter-kill" is also very common in Go. It is by no means a rare thing. If you intend to guide it, you can play "counter-kill" in 5 out of 10 chess games.

   Speaking from the bottom of his heart, Li Xiangping dared to promise Lao Shi to challenge dogs in the future. This is actually one of his sources of confidence. Again, as long as dogs still have weaknesses, humans should still have a chance.

  Li Xiangping is of course clear in his heart that he really wants to challenge the dog. Of course, this alone is not enough. Except for this extreme probability situation, in other ordinary probability, he cannot be pulled too far by the dog.

   But fortunately, isn't it more than ten years away from the birth of "Alpha Dog"? In Li Xiangping's view, he is now studying the internal chess theory of "dog moves", which is actually studying those problems of ordinary probability.

  Li Xiangping is going to spend more than ten years to solve this problem �

   I don’t want to surpass the dog, but I don’t want to be pulled too far by the dog. If this can be done, then Li Xiangping thinks that if he and Lao Shi work together, he may be able to fight the dog.

Of course, this is a secret buried deep in Li Xiangping's heart. It is a secret that he cannot share with anyone except Lao Shi. Therefore, in the face of Cao Jiuduan's enthusiasm, Li Xiangping can only smile hypocritically, Then say something like "You're welcome" and "I'll ask you for advice when I have time", and then get off the topic.

   The focus right now is, of course, the ongoing "Celebrity Battle".

After taking Cao Dayuan's ninth dan lightly in the first round, in the second round, Li Xiangping once again encountered a local chess player whose rating score was out of 50. In this chess game, Li Xiangping still did not encounter any decent resistance, he was relatively relaxed advance to the 3rd round.

   In the third round, Li Xiangping finally encountered a hard stubble, and in everyone's opinion, this game is still very interesting.

   Not because of anything else, because this opponent's name is Luo Xihe.

   is the "Luo Shenpig" who is as famous as Chang Hao and has a test IQ of 169.

   He is quick-witted and quick to react. He often shoots like lightning when he plays chess. Unfortunately, after Li Xiangping was born, his reputation as the fastest chess player in the national team seems to have been snatched away.

   The current "celebrity" is Ma Xiaofei, and classmate Luo Xihe is precisely Ma Xiaofei's entrant disciple.

   It's just that in Li Xiangping's view, these are not important. The most important thing is that Xiaozhu has just cut himself in the armor not long ago, so today he wants to take revenge.

   "Haha it's a little pig, it's a little pig, finally let Li Xiangping meet a little test"

   After the results of the match came out, not only Li Xiangping himself, but also many reporters finally got a little excited.
