In the last round of online PK competition, after all the strange-shaped Sudoku in the previous round, we returned to the standard Sudoku, which is often called the nine-cable grid. Of course, the final standard Sudoku is a difficult problem, and it is quite difficult for ordinary people to solve it.

Thesky can solve the problem in half a minute for the low-level standard Sudoku, but thesky can solve the problem in half a minute, but thesky can solve the problem in average about two minutes. Because each question is different, there is no such thing as a world record, and only the world rankings, thesky is the first.

The system suddenly said: [This is the first live broadcast by the host, and it has obtained a lot of admiration. With the host's women's clothing, it has caused considerable influence. This system decided to increase the host's brain power.]

Li Xuan was surprised: "System, you are rarely so proactive."

System: [Host, please understand that you must not lose when wearing women's clothing! This is related to the face of the women's clothing industry in the future! Please take the last round seriously!]

Li Xuan was speechless, which one wants to save face?

System: [It is recommended that the host use the trial method, do not rely solely on logical reasoning, otherwise there is no possibility of winning thesky! Don’t laugh, please be serious!]

Sorry, Li Xuan still couldn't help but want to laugh.

It seems that he was not serious before. He was very serious about writing Sudoku. If he didn’t take it seriously, he would not make any progress.

However, the system is right. In this international website Sudoku online competition, he basically uses logical reasoning to get answers, and rarely uses the method of trial numbers to violently calculate. In fact, the more difficult the question is, the better the method of trial numbers is than logical reasoning.

There is a principle of unique solution for Sudoku, and it is natural to try to eliminate the answer. Many people who play Sudoku make rapid progress in competition. Li Xuan is also making rapid progress in competitions and proficient in Sudoku solution skills. In particular, Li Xuan's remaining point calculation skills have gradually become perfect.

The last round seemed very difficult...

From the serious tone of the system, Li Xuan realized that thesky's trickyness might be an opponent he could not defeat at the moment. Although he has strong computing logic and reasoning skills now, he has not had much time to contact Sudoku, and his proficiency is definitely not as good as professional players like thesky.

Li Xuan is just playing Sudoku, and he will not be addicted to it. There is no difficulty for him to play Sudoku. He can write a program and find out this standard Sudoku solution with a hundred lines of code.

Compared with thesky, his advantage is very obvious, his computing power is strong, and his weakness is that he does not have enough understanding of Sudoku. If he has a high understanding of Sudoku, it will be easy to deal with thesky.

For example, AlphaGo defeated the number one player in Go, and its artificial intelligence computing power is far superior to that of humans. As long as you improve your understanding of Go, it is completely normal to defeat humans.

Because Li Xuan has been wearing women's clothing more often, his brain power has been improved by the system to far exceed the public level. In terms of computing ability and reaction ability, compared with thesky, he also has the advantage of innate talent. If you want to defeat thesky, you can do it after training for a period of time. It is just a matter of time.

Especially Sudoku, there is no profound mathematical knowledge involved. For players who can enter the national team of Mathematical Olympiad, it is very simple to reason and summarize the skills in Sudoku. When Li Xuan was playing Sudoku, he had already deduced some Sudoku skills by himself based on the rules of Sudoku. Later, he went to the Internet to teach Sudoku skills and found that it was exactly the same as his understanding.

For Li Xuan, playing Sudoku is the same as playing mathematics. There is no essential difference between finding skills in Sudoku and solving math problems. The core of Sudoku is to exclude.

Li Xuan vaguely remembered reading a news story that someone in Sudoku national team seemed to be allowed to Tsinghua and Peking University? It seemed that he was a genius who won awards in mathematics and informatics.

The difference between the Mathematical Olympiad national team and the Sudoku national team is that the former has terrifying logical reasoning, while the latter has terrifying computing speed and reaction ability. If you want to enter the Sudoku national team, your computing ability must be extremely strong. Li Xuan is a type that is strong both, which means that your talent has not been converted into strength in Sudoku.

After thinking for a while, Li Xuan decided to make a mistake in the end. He had a sense of numbers that was more powerful, and with his super calculation ability, the method of trying numbers was more suitable for him.

The countdown soon began. When the countdown returned to zero, the nine-grid on the web page appeared on time.

Li Xuan looked at it and saw 26 numbers in the nine-client grid.

Ordinary people often have misunderstandings, as if the fewer numbers in the nine-cluster grid are, the more difficult it is. In fact, this is not the case. The difficulty has nothing to do with the number.

After seeing the nine-cup grid, Li Xuan did not fill in the numbers immediately. The calculation process was completed in his brain, and he did not fill in it at first glance. It seemed that he didn't know how to do it.

Of course, he can save unnecessary waste of time by completing all the operations in his mind like this.

Others can't do such a terrifying thing as calculating power as Li Xuan. Not everyone in this world can have the ability to process huge amounts of information in their brains.

As time passed, Li Xuan looked at the computer screen without blinking, and silently calculated in his heart, as if he had entered another illusory time and space.

The numbers are stacked and the changes are sinking into the darkness. Where does he want to see the light?

Others started to fill in the numbers one after another, but Li Xuan did not start to take action. The completion degree displayed on the side was still 0%, ranking lasting for the last fourteen contestants in the last round.

The first time I saw Li Xuan fill in a Sudoku viewer, it would be very strange to see Li Xuan's progress.

Chat room chat:

“dotheyes deceive me?lixuan falling behind all players? (I read that right? Li Xuan lags behind all contestants?)”

“that's howasprevious races and thenbeat the socks off the others!”

“ yes,i've seen this case dozenstimes. (Yes, I've seen him like this several times.)”

After a minute, Li Xuan's completion rate was still 0%.

Li Xuan and thesky had the shortest accumulated time before, ranking in the top two. This battle was the focus of the audience's eyes.

Many viewers saw Li Xuan's progress and thought it was a display problem. After refreshing the web page several times, the result was the same. Li Xuan did not start filling in the first free space. This made many viewers suspected that they were so much behind at the beginning, and they could really catch up in the end?

Especially when facing players of thesky level, thesky also fills in the front slowly, and the speed becomes more terrifying as the closing stage comes later. No matter how you think about it, it is impossible to catch up.

Not to mention thesky, they are all masters among the masters in the last round. The difference is a slight mistake. Most contestants think of where to fill in the first blank in a few seconds, but Li Xuan has not taken action yet. This situation of falling behind other opponents in total was also the first time Li Xuan encountered in the competition.

In Li Xuan's live broadcast room, the audience didn't know what opponent Li Xuan was competing with, and didn't know that China's Sudoku has only developed for a few years, but they were still more confident in Li Xuan.

Li Xuan thought about it while filling in the numbers at the beginning, but it has been like this since the last few rounds. He didn't do the question immediately. He thought about it for a while, and then completed the Sudoku at an outrageous speed.

The audience was shocked to the point of being a little numb when they saw Li Xuan's monster-like problem-solving speed, and only had mercy for the temporarily leading contestants.

Live broadcast room barrage:

"Okay, I'll be at the bottom at the beginning, and I'm stunned when I wait for international friends."

"Waiting for international friends to be stunned +1."

"Anchor is good or bad, will he make a big splash again?"

"Mom, they are really masters. Some people have completed several free time. The anchor should do it quickly, otherwise they will not be able to catch up! One minute has passed!"

"This time the standard Sudoku is more difficult? The anchor has thought about it for so long but hasn't started writing yet?"

Of course, many viewers didn't say anything, looking forward to Li Xuan's counterattack, for fear of sending barrage to miss the last wonderful moment.

There was a delay in the barrage, and Li Xuan didn't pay attention, so he thought attentively.

...

...

In the last round of the Sudoku PK competition, some participants were distracted because they paid too much attention to the rankings, and the progress bar was stuck. The highest completion rate was 70% of thesky.

In a small house in an island country on the other side of the sea, thesky sat in front of the computer to solve the problem. Because Li Xuan accumulated a short time, it was a certain threat to her, and she was also paying attention to Li Xuan's ranking. At this time, she saw Li Xuan's progress, and felt that her first one was stable.

More than ten seconds passed, and Li Xuan had a light of inspiration, thought of the answer, and began to fill in the number.

An accident happened under the eyes of the audience. Suddenly, Li Xuan's completion reading bar changed, rising at a speed visible to the naked eye.

Li Xuan's completion rate jumped rapidly from 0% to 100%, and directly entered the closing stage from zero. Without intermediate thinking process, it soared into the sky.

No. 14.

No. 13.

No. twelfth place.

...

Third place.

Second place.

Finally, first place!

The ranking jumped quickly, Li Xuan's name was rising, and he stood at the peak in a blink of an eye, pressing on all the players, including thesky.

Unprepared, Li Xuan came up like a rocket.

The spectator was stunned at such an incredible speed.

This ranking speed has a great visual impact, which brings a sense of shock that makes people wonder if Li Xuan suddenly got the answer.

I have never seen anyone who solves Sudoku problems like Li Xuan, and have to re-examine it. Is it that Li Xuan’s calculations completed in his brain?

Li Xuan's progress is 95%.

At the same time, thesky entered the closing stage, and she was about to complete it. At this time, she accidentally glanced and saw Li Xuan's progress, and she was lost in her mind. Because of this loss of mind, her concentration decreased and she didn't have time to fill in the last few blanks.

The next moment, Li Xuan's completion rate was 100%.

After Li Xuan finished, thesky's thoughts came back, and the completion rate reached 100%, which took 59 seconds per minute.

The chat room exploded instantly:

“wow! that's amazing! (Wow, amazing!)”

"please tell what happened? (Please tell what happened?)"

“lixuan won this time.(Li Xuan won this time.)”

“lixuanthe craziest person i've met. (He is the craziest person I've met.)”

“thesky finished almost three secondsarrears for second place.(thesky finished almost three seconds behind and won second place.)”

“lixuan saidis chinese (he said he was Chinese.)”

...

After filling in the Sudoku, Li Xuan breathed a sigh of relief when he saw the message that he was the number one pop up on the webpage. He didn't know why his mind suddenly became blank and he fell into a state of confusion.

Turning around and looking at the live broadcast room, the barrage was flooding the screen:

“666666666!”

"The final action was so cool!"

"It's really cruel!"
