"Our Alpha Go, we can also do 120 hands after all the hands - if the middle two sides do not have large-scale robbery, change, being eaten, etc., resulting in the board is too empty - and Hatsune knows more about Go than our Google team, and started half a year earlier, the value trade-off algorithm must also have advantages, it is estimated that Gu Mojie will completely let go after 100 hands, and the hard thinking and meditation behind are all pretending to show you!"

"Gu Mojie's machine must be the same as our Alpha Go, with the function of 'telling the user whether the current steps are expedient measures to save time after weighing the pros and cons', so Gu Mojie is absolutely impossible to think about every step there. So the number of moves that you think a professional chess player should judge right away, he must also be pretending to be for you to think. ”

A group of Google engineers who were received by Lee Sedol overnight took advantage of the work at the dinner table to tweet a lot of things for Lee Sedol, which made people upset.

Before Lee Sedol wanted to be irritable, Dean Liang of the Korean Chess Academy, who came to watch the game with him, opened his mouth to play a round:

"Alright, Professor Huang, let's make a long story short. After all, Li Jiuduan still has to rest, and he is already very tired after a day of chess today, and he must empty his brain after 9 o'clock. You only have two hours, don't talk about it if it's useless. ”

Google's person in charge of the value-trade-off algorithm from Wanwan, known as "Professor Huang", immediately stopped talking, and asked his commentators to stop.

"I'm sorry, but I just said it casually. Fully understanding the opponent is also helping Li Jiuduan to win. Later, we will focus on what benefits Alpha GO can bring tomorrow and how to cooperate with Li Jiuduan tonight. ”

Professor Huang said, signaling Lee Sedol not to waste time, just eat and listen at the same time.

Lee Sedol was not polite to him, others were chatting around him, and he hurried to have dinner.

The food provided by Jiangnan Club is definitely the pinnacle of Chinese cuisine, and in order not to be honest, the hospitality of Lee Sedol these days can be described as extremely luxurious. But when the dragon liver and phoenix pith are eaten in his mouth, Lee Sedol feels that there is no taste.

It's better to pour two mouthfuls of spicy kimchi when you win the game.

Professor Huang and his assistant explained to Lee Sedol in turn:

"Although Alpha GO is not as perfect as the first line, the official is definitely fine. I think you will not win or lose until 220 moves in today's game. In fact, the last 50 hands after 170 hands, if both sides are robots, the result must not change no matter how many times you play, and it only takes 15 minutes to complete those 50 steps. ”

Normal humans play Go, and the last 50 hands add up to more than 1 hour, while robots can do it in 15 minutes, which is equivalent to saving at least 1 hour of total game time compared to human chess.

This time can be better allocated to the previous steps, and each person has more than half an hour to think.

As for the specific steps Lee Sedol walked the next day and then completely let go of Alpha Go, Lee Sedol was ready to try a few mid-game endgames of about 150 hands with Alpha Dog after eating - from the relatively close chess games he had played against his opponents in his own history - to try the level of Alpha Go.

"In addition, Alpha GO doesn't have any ability in the layout stage, it can only give you some reference formulas, and you can pick out the best result after reading it - we can only guarantee that the best result must be within the eight-screen option, but which one is specific, Alpha GO can't judge."

"Alpha Go also has a tool called 'Value Judgment Network', and when the time comes, after giving the machine's opinion, it will make a judgment on the screen and tell you, 'There is absolutely no better solution for this step', or 'the machine doesn't know who is the best, but it just doesn't have time to think about it for the time being'. So those machines are willing to pat your chest and tell you that this is the best answer, and you can also save some thinking time. ”

When Lee Sedol heard this, he stopped his chopsticks and personally confirmed the operation of this thing to Professor Huang.

Professor Huang didn't hide it either, and told him frankly: there are actually two sets of sub-algorithms in Alpha Go, the first is the algorithm that absolutely exhausts the best possibilities, but it takes a lot of time. Even with Google's cloud server fleet and accumulated chess game big data, it will take a long time to calculate a move.

After all, Go is the most computationally intensive game in the traditional chess game of mankind today. Compared to chess and chess, the possibilities of Go are simply astronomical.

Therefore, the deep learning of Alpha GO is mainly reflected in one point: when the algorithm is found to be seriously timed out, it will make a time-saving judgment, and the next one is not too bad. And this monkey version of the time-saving algorithm only needs one hundredth of the time of the first type of exhaustion algorithm.

After eating, Lee Sedol used some tea, took a short rest, and studied the run-in method with Professor Huang's team.

However, after all, he can't compete with Gu Mojie's ability in the field of artificial intelligence to test his understanding and cooperation with artificial intelligence.

A habit that has been formed over the years, let alone a few nights that can be reversed.

After sharpening the gun, in the end, Lee Sedol saved about 1 hour of thinking time and saved a lot of brain power in the next day's competition.

It's like a candidate taking a high math exam and is allowed to bring a calculator. However, the calculator does not solve advanced math problems, but only helps the answerer save some time and reduce some low-level errors.

……

The eyes of the whole world continue to stare at the pool pavilion of the Jiangnan Society.

The exposure of billions of people has formed a highlight moment that is stronger than the World Cup final.

Google has struck! Finally, it is not the man-machine that fights the real person, but the man-machine fights the man-machine!

Both sides are the ultimate showdown!

December 23rd, the third battle!

Gu Mojie held the black and returned to Gu Liliu's "big win rate against Li Xianxing" mode. At the beginning of the game, a series of imaginative and violent layouts suddenly limited Lee Sedol's play space by twenty or thirty hands, which also made Gu Mojie slightly relieved.

A fierce fight ensued.

Gu Mojie has fewer and fewer times when he can play a role, and most of them are handed over to the first line. It is only when certain initial lines give "high-risk" and time-consuming steps that Gu Mojie can arbitrarily deal with them - and basically every time this kind of disposition occurs, it will reduce Gu Mojie's market estimate by about half an eye.

But he couldn't help it.

Only when the authorities look very similar to the formula in the thousands of games that Gu Li gave him special training in the previous months, or very similar to the historical record of Gu Li's battle, will Gu Mojie completely play it himself.

"Google's engineers can teach Lee how to use the AI assistant and how to allocate time with the AI. But the people at Google certainly don't know much about Go circles. The Americans don't have a first-hand look at the specific mental process of the confrontation between Coulee and Lee Sedol - so the help of Alpha GO in the layout is tantamount to a waste! ”

Gu Mojie took a deep breath repeatedly, imprinting this impression in his mind.

60 hands, Gu Mojie is estimated to be 2 disadvantages!

Barely able to hold up to 80 hands, estimated disadvantage of 4 meshes!

Gu Mojie's forehead was already sweating.

Could it be that the "14th section of the middle game" in the first line can surpass Lee Sedol by more than 4 meshes in the middle game?

You can only look at the sky.

When it came to 100 hands, Gu Mojie stopped pretending, left the table to rest, and asked a waitress to play chess according to the instructions of Chu Xing. He himself was in a cold sweat, and he was able to chat with the senior master Wu Qingyuan next to him.

This is equivalent to telling the other party: after the first 100 hands, you can already let go!

As for whether the Americans and Lee Sedol believe it or not, Gu Mojie doesn't care, this strategy of being virtual is also a weight to shake the other party's mentality.

Anyway, there are no real people on Gu Cheng's side, and it is impossible to be emotionally affected.

Disadvantage 3 mesh ...... 1 mesh ...... Pulled! (stickers already included)

Wu Lao is 99 years old, his body is really not good, he has slept several times when he watches a game of chess, and there are many waiters waiting next to him.

When Gu Mojie was off the field, he just woke up.

"Luck! Today's plate is a bit hanging. Fortunately, the strength of Alpha GO's mid-game is not as good as that of Lee Sedol, but what to do next? I'm going to win three out of five games, satisfied? ”

Gu Mojie wiped his sweat unwillingly: "I can't be satisfied, at least I have to win one more set, otherwise, wouldn't it be said that 'in the three sets after Google's Alpha Go competition, Lee Sedol won 2 wins and 1 defeat - doesn't it mean that Google's artificial intelligence is stronger than Chuxing!" ’”

Wu Lao narrowed his eyes and nodded wisely: "How can you say that." Lee Sedol plus Alpha GO is stronger than you plus the beginner, and that doesn't prove that Alpha GO is stronger than the beginner - after all, Lee Sedol's level is higher than yours. Today, if Xiao Gu is allowed to fight with the beginner and Lee Sedol with Alpha Go, at least he will win Lee Sedol by more than 20 meshes, or the opponent will admit defeat if he has less than 150 sons. ”

Gu Mojie thought about it, and he really had a bull's horn.

Let a person like Gu Li lay out the nine sections, compared with Lee Sedol's layout of the seven sections, and everyone let go in the later section - isn't that a bully?

"Anyway, I'm going to have to figure it out." Gu Mojie adjusted his mentality and said.

Wu Lao shook his head and poured a little cold water on Gu Mojie: "It's not that easy, Gu Li has a great chance of winning first, and he can hold Li Shishi's layout routine." Tomorrow it will be Lee Sedol's turn to take the lead in black, and it will not be so easy. ”

Gu Mojie rested for a while, and the third game on the field was finally decided.

Sure enough, with robots on both sides in the battle, the total duration of the game was shortened a lot. Lee Sedol had tried to take as much time as possible in front of him, and finally ended the match before 3 o'clock in the afternoon.

Lee Sedol was defeated again.

But he also accumulated some experience with robots.

The next day, the fourth battle.

Lee Sedol took the lead in black, and he seemed to realize that he couldn't be led by the opening routine of the "Gu Li Game" in the first 20 hands, and he had to try to play differently.

Gu Mojie fought hard, and finally lost miserably because his "physical" strength was too bad.

After four rounds, the final score was 3:1!

In terms of best-of-five games, Gu Mojie has already won this game.

But according to Google's results after joining Alpha Go, the two sides are now 1:1.

……

"No! Lee Sedol must not be given a chance to turn the tables. It must be proved that Hatsune has an absolute advantage over Google and other opponents on the planet in terms of deep learning artificial intelligence! ”

"Otherwise, how can we quickly promote artificial intelligence push and assistant products? How to boost the morale of the people, so that everyone can respond to try our products as soon as possible, and provide us with more complete big data! ”

For the sake of market confidence, this battle cannot be lost.

Gu Mojie thought a lot.

Lee Sedol is making progress, and this progress is not the progress of chess skills, but the progress of man-machine cooperation.

Tomorrow's final battle is for the two sides to draw lots to determine who will take the lead in black.

The number of sunspots in China's Go rules is four to three-quarters, which is relatively rare in the international arena -- some of the more ruthless rules stipulate that the number of sunspots can reach seven meshes.

Therefore, compared to those rules, the rules of Chinese Go have made Heizi earn more than two eyes.

Judging from the trend of Gu Li's special training, Gu Mojie's preparation If he takes charge of the black tomorrow, he still has a certain degree of confidence in using the beginner to kill Lee Sedol.

However, if the draw is drawn to Lee Sedol Kuroko...... It's hard to guarantee that today's fourth game won't be repeated.

"Don't think about it, eat well first. You're not a professional Go player. Hatsune Intelligence's forced grid brush to this step is enough. ”

During the meal, Lu Wenjun felt sorry for her husband, and when she saw that he was absent-minded and a little crazy, she couldn't help but persuade her.

"I don't have an appetite, I'll go to Hujiang to eat in a while - let Sister Xiaoru prepare the helicopter. I'm going to go to the big data center over there. ”

Lu Wenjun watched Gu Mojie leave mysteriously, and felt a little surprised in his heart.

"It's Christmas Eve, what are you going out to fool around in the middle of the night?" (To be continued.) )
