"After a while, the robot will officially start up. Please help me. Don't get too close to me, otherwise it may affect the operation of the robot. Also, please help me to keep quiet."

Zhao Yi was experimenting with high technology in his own supermarket, and the fat boss felt very honored. He quickly stood up and said loudly, "Everyone be quiet! Be quiet! This is a high-tech experiment! It's not for you to watch a show."

Many people laughed out loud.

Zhao Hongjuan and Lin Xiaoqing were also among them. Lin Xiaoqing and Zhao Yi stood very close, and Zhao Hongjuan also helped to greet her, "Everyone help, calm down, and look at Xiaoyi's robot, don't get too close."

Zhao Yi asked them to help watch the machine, and went into the supermarket to check the environment by himself.

The fat boss is prepared.

The distance between the shelves of the supermarket has been enlarged, and the inside has become much tidier. There are no obstacles such as boxes between the shelves, which will make the robot run more smoothly.

After seeing the environment inside, Zhao Yi went outside and waved his hands, motioning for everyone to calm down.

Xu Chao went over and stood on the steps at the door, leaving only the barrier-free passage, and the robot could turn directly to the barrier-free passage, calculate the slope and climb up along it.

The test officially begins.

Zhao Yi turned on the robot.

After the robot system is loaded, immediately say a sentence, "Robot, Dongdong, is on standby!"

"Push!"

Zhao Hongjuan couldn't help laughing, quickly covered her mouth and looked around, then gave Lin Xiaoqing a hard look.

She knew that the name had nothing to do with Lin Xiaoqing.

carry on.

Zhao Yi said, "Start the shopping mode, go to the supermarket directly ahead, and buy two cucumbers, a pack of tissues, and a box of milk."

"complete."

"Instructions received!"

The robot stopped for about two seconds, turned on several cameras, and walked straight ahead.

Xu Chao stopped right in front of him.

The robot stopped at a distance of about [-] meters from Xu Chao, then moved laterally to the corner of the barrier-free passage, then turned left and right to check, walked forward for a short distance, and finally stopped directly in front of the barrier-free passage, and then followed the slope climbed up.

"Hu~~"

The people outside couldn't help shouting.

Even ordinary people who don't understand it know how difficult the wayfinding process is. It is absolutely remarkable for a machine to stagger the front door with steps and find a barrier-free passage to climb up.

The robot walked to the main entrance of the supermarket, then stopped and turned to enter the supermarket, and came to the outermost vegetable area.

The fat boss's supermarket is not big, with only six rows of shelves in the middle, and a whole row of shelves against the wall. The vegetable section at the door has two rows of vegetables and fruits, and there is an aisle in the middle.

The robot walked down the aisle, looking only in a single direction, and quickly stopped in front of the cucumber.

After a gap of about two seconds, the robot stretched out its robotic arm to grab a cucumber and put it in the shopping basket behind it, then turned around to grab a cucumber and put it back in the shopping basket.

"Hula~~"

"Clap clap~"

"He did it! He did it!"

The onlookers at the entrance of the supermarket were all more excited than Zhao Yi, some shouted excitedly, some simply applauded, the fat boss is a rare calm person.

He hurriedly pressed his hands and shouted, "Quiet, quiet!"

The crowd quieted down.

The robot did not leave the vegetable area, but continued to walk along the aisle, checking the vegetable area continuously, before reaching the next aisle and entering the shelf area.

The front of the shelf area is full of wine.

The robot walked quickly, almost without stopping, until it reached the second row of beverage area, and then started to stop continuously, and the sound of 'buzzing' was obvious in its stomach.

It was the sound of a fan.

When the amount of calculation becomes huge, the CPU usage rate becomes higher, and the cooling speed of the fan will also be accelerated.

There are many items in the beverage area, all of which have similarities with 'boxed milk', so they cannot be eliminated immediately, and the amount of calculation will increase immediately. The robot stops in the milk area, but in the end it still does not make a selection, but continues to go forward.

"call……"

Many people feel like they have failed.

Lin Xiaoqing also asked Zhao Yi, "Did it fail?"

"No." Zhao Yi didn't care, "Because I didn't set a 100% matching data with the boxed milk."

"why?"

Zhao Yi just wanted to speak but got stuck. He felt that it was too complicated to explain this question to Lin Xiaoqing, so he simply said, "You will know it when you look at it."

"Tell me!" Lin Xiaoqing was very dissatisfied.

Sun Liang also said, "Zhao Yi, explain, explain, I don't quite understand either!"

"All right!"

Zhao Yi simply spoke up.

The robot judges items by design and recognition, and the most basic thing is through color recognition. He adopts the method of "fuzzy calculation" and covers the largest range, even if it is what color.

For example, on a milk package, because there is a cartoon character image, any color may appear. Using the method of "fuzzy calculation", if the area covered by a certain color exceeds 50.00%, it will not be counted, but the color of the item will be directly assigned to the Cover the highest color.

Milk is defined as white.

However, there are many 'square' box-shaped items in white packaging. If the text cannot be recognized, other judgments are required, such as the range of box size, weight, and so on.

When all the conditions are met, it is still impossible to judge 100% that it is milk, because there are still many similar things.

Zhao Yi didn't make a 'sure' judgment at all.

He made dozens of possible related judgments and classified them, and made a percentage for each judgment, and finally determined the item through the percentage. Items that exceed the conditions of 90.00% five will be determined to be certain items.

This vague method is also the way the human brain judges.

In fact.

If it is just to judge items, of course there is a better way, but what he wants to do is a 'human-like' approach, rather than simply calling data to make judgments.

At the same time, judging must also be done in a unified way to achieve common codes. It is impossible to change another method for simple or complex items, which is equivalent to rewriting a set of codes to identify an object.

That is not advisable.

So when it comes to judging items, some things, such as cucumbers, are very simple and can be judged directly, while things like milk, with packaging, and many uncertain factors, make judgments more complicated.

During Zhao Yi's explanation, the robot continued to walk around the supermarket after successfully selecting the tissue.

After turning all the positions, he walked to the door again, stopped suddenly, turned and walked towards the milk area, stopped directly to take a carton of milk, and then returned to the door.

"It got it!"

"What's going on? Can't you get milk?"

"awesome!"

The crowd at the door cheered again.

This time, everyone didn’t care about the sound, because the robot completed the order and got the tissue, cucumber and milk. Some people simply asked Zhao Yi, “Where did you buy it? It’s so advanced?”

"Is this robot for sale? I want to buy one too?"

"how much!"

Zhao Yi first turned off the robot in the past, because it was prompted that the battery was low, and it was definitely not advisable to force it to shut down because it was out of power, which might damage the system or files.

When I came back, I smiled and said, "I bought the machine for tens of thousands of dollars, and I designed the program in it myself."

"This is amazing!"

"By the way, it's all because Zhao Yi is a mathematician and solved some mathematical problems. In fact, he is a computer expert!"

"hacker!"

"Hackers are amazing!"

Zhao Yi forced a smile on his face and complained dozens of times in his heart, "Does this have anything to do with hackers?"

……

testing successfully!

Although many problems were exposed in the middle, at least the core functions were played.

Wayfinding, no problem.

There is no problem with item recognition.

In fact, Zhao Yi only entered ten kinds of items in advance, and the others have not been entered yet, but the follow-up is a crossword puzzle. With basic compliments, just ask Xu Chao to put things in it.

There is still a celebration banquet.

night.

Zhao Yi invited a big meal.

Xu Chao, Sun Liang, and Zhao Hongjuan's mother and daughter all went. Several nearby neighbors, including the supermarket owner Wang Ge, also gathered together for a table. Zhao Yi paid the bill very generously, and the neighbors would sometimes help and take care of , invite guests and deepen the relationship.

When a group of people were eating and drinking, photos of Zhao Yi testing the robot had been posted on the Internet.

It was taken by a mobile phone.

The pixels of the photos are very poor, but the number is very large. There are more than 40 photos in total, all of which have been uploaded on the Internet. Someone exposed what happened and the whole process of the robot selecting items.

In addition, someone uploaded a short video of the robot entering the supermarket.

Putting videos and photos together is very convincing. Most people just watch the fun and feel the current smart high-tech. Robots can actually complete shopping in supermarkets like humans.

Professionals are different.

Zhou Kai, manager of Haitian Technology, is a professional. They have been researching a smart technology that can identify objects, and they never expected to see it on the Internet.

"is this real?"

"It doesn't look like a fake, how could an experimental robot appear in..."

"This person is..."

Zhou Kai was skeptical at first. He felt that high-tech intelligence usually only appeared in the laboratory, until he saw a photo with a face he seemed to have seen before.

"Is... that genius high school student?"

Chapter 163 Magic Cracking Master

Zhao Yi can be regarded as a small celebrity, and his fame mainly comes from "cracking the Jiaogu conjecture".

The "Kakutani Conjecture" does not involve prime numbers, and it is not an extremely difficult conjecture in number theory, but it has become very famous because it is "simple and easy to understand".

This makes sense.

It is difficult for people to remember the names of those complex mathematical problems, but they are impressed by the mathematical problems they can understand.

The name of "Goldbach's conjecture" will appear in the textbooks of middle school and even primary school, but Goldbach's conjecture is not the "first problem in mathematics". Fermat's conjecture, which has been proved, is on the same level as Goldbach's conjecture.

In the field of prime number problems in number theory, Riemann's conjecture is much more valuable than Goldbach's conjecture, and it has been applied to many fields before it has been proved.

Riemann's conjecture and Fermat's last theorem are mathematical problems that are not inferior to Goldbach's conjecture, but Goldbach's conjecture is more famous than them, because Goldbach's conjecture is simple and easy to understand, as long as you know the definition of prime numbers, You can know what the guess is.

The same goes for Kakutani's conjecture.

The Kakutani conjecture has become so popular that it has become a small mathematical game, and it will naturally cause a sensation when the conjecture is proved.

Zhao Yi proved Kakutani's conjecture, which greatly increased his reputation.

This is just the beginning.

The education departments of some provinces have already planned to add an extracurricular story about "Chinese high school student Zhao Yi cracks the Jiaogu conjecture" in the textbooks of middle and primary schools. In the future, Zhao Yi may become "a rare living character in the book".

Therefore, most people think that Zhao Yi is a genius mathematician.

People in the computer industry are different.

They remember that Zhao Yi mainly used the "effective and irrelevant carry screening method", and the proof of Kakutani's conjecture also came from the "effective and irrelevant carry screening method".

The computer and Internet industries are at the forefront of the times. People in the industry must keep up with the times, otherwise they will be eliminated quickly. Zhao Yi invented a brand-new algorithm, which provides a new algorithm idea for the computer industry all over the world. It will definitely be widely used in the future.

Therefore, people in the computer industry can associate Zhao Yi's name with the "screening method".
