"Me too."

"Do you think it's okay to wear the kind that reaches the knees? Ordinary ones, or gauze skirts? I think the gauze skirts are too revealing, so I dare not wear them. If it's thicker, will it be too hot?"

"It's okay, my mother is here, just ask her, she studies this every day."

"Your mother's clothes are so fashionable. I watch TV, people on the beach wear that kind of clothes, just cover...and foreigners, upper body...hehe..."

"What are you talking about! Are you ashamed!"

"Tickle you!"

"I scratched you..."

Zhao Yi looked at the books on the table, his eyeballs were still in their sockets, and he didn't move for a moment, and he kept thinking silently, "Form is emptiness, emptiness is form, women are tigers..."

"Women are monsters..."

"Women are devils..."

"Read carefully, don't go astray, don't go astray!"

The cow lotus is still majestic.

The two girls didn't dare to have too much fun, and they seemed to feel boring after talking for a while, so they shifted their attention to Zhao Yi.

Lin Xiaoqing stared at the books on the table and asked, "Zhao Yi, is this mathematics?"

"Correct."

"University mathematics?"

"No."

"What is it, what is it." Zhao Linlin also leaned over to take a look, and found that the content of what she said was very novel, most of which she couldn't understand, so she felt boring, "Leave him alone, he is a pervert, obviously In high school, he felt better than college students."

The two girls smiled and sat back.

Zhao Yi looked up and shook his head silently. He was indeed studying hard, not just memorizing textbooks, but learning something new.

This is a New Year's gift from Professor He.

Ok.

Consider it a gift for now.

Zhao Yi received a stack of materials, including two professional reference books, and two handwritten notes, all written by Professor He himself. .

The core content of the book and notes revolves around one point: fuzzy mathematics.

Modern mathematics is based on set theory. The significance of set theory is that it can extend the abstraction ability of mathematics to the depths of human cognition process: use sets to describe concepts, and use set relations and operations to express judgments and Reasoning, so that all realistic theoretical systems are included in the mathematical framework described by sets.

no doubt.

Accurate mathematics and stochastic mathematics based on classical set theory have achieved remarkable results in describing the internal laws of various objective phenomena in nature.

However, like random phenomena, there are a large number of fuzzy phenomena in life, such as cloudy, overcast, light rain, heavy rain, poverty, food and clothing, etc.

Since classical set theory can only limit expressiveness to phenomena and concepts with clear extensions, it requires that the affiliation of elements to sets must be clear and not ambiguous. Therefore, for those concepts with unclear extensions that cannot be reflected by classical sets, Scientists try to avoid them as much as possible.

With the continuous development and progress of science, there must be a system that can extend beyond the classical set theory to describe those uncertain concepts.

This is fuzzy mathematics.

The concept of fuzzy mathematics breaks away from the conventional mathematical system, but it has broad prospects in the field of application.

For example, computing.

When those complex calculations that are difficult to determine are discarded, the calculator based on fuzzy mathematics can increase the calculation efficiency by a hundred times or a thousand times.

The fuzzy inference machine developed in China 20 years ago - the prototype of discrete components, the inference speed has reached 1500 million times per second, which marks a very important step in breaking through the difficult technology of fuzzy information processing in China.

In the field of fuzzy mathematics, decision-making and artificial intelligence are the most promising prospects.

In the field of major decision-making, such as deciding some major affairs, you have to face a lot of uncertain factors, you can use the theory of fuzzy mathematics to make the decision-making more accurate as much as possible, rather than "gambling-gambling" Just like that, a decision was made in a snap of the brain.

The Three Gorges Dam is an example.

During the design and construction process of the Three Gorges Dam, many uncertain factors will be encountered, and the decision-making is related to a century-old plan, so it is definitely not possible to make a decision directly.

At that time, Professor He used the concept of fuzzy mathematics to make detailed auxiliary calculations to help senior officials make final decisions.

This is Professor He's battle for 'fame'.

After that, fuzzy mathematics was paid attention to in China, but in fact, because the content of fuzzy mathematics research is inherently uncertain, many people in the field of mathematics are very resistant to fuzzy mathematics. They think that fuzzy mathematics is not real mathematics. It's a bit like literature and philosophy.

In addition, fuzzy mathematics is very high-end in the field of application, which directly affects the popularity of the subject.

Professor He has been studying fuzzy mathematics all his life, and he is well aware of the development of fuzzy mathematics in China. Most colleges and universities do not have relevant courses, and there are only a handful of people who have in-depth research on fuzzy mathematics.

He hopes to pass on what he has studied all his life.

After Zhao Yi received the books and manuscripts, he took the time to study them patiently. He found that what Professor He said was right, fuzzy mathematics and artificial intelligence were very suitable.

For example, calculate.

Ordinary computers perform multiplication by first converting two numbers into binary, and then using the rules of binary multiplication to calculate accurate results step by step.

The human brain is different.

If you ask the result of multiplying 134 by 257, it is difficult for most people to calculate. If you want to make the answer more accurate, you may calculate it in this way, first calculate 13x25, and find that it is 325, and then you can get a result, "should be in About 350 million, and the last digit is 8."

This result is ambiguous.

In real life, many things do not need to be very accurate, what is needed is only a 'fuzzy' answer. In similar matters, the human brain can outperform the computer and quickly obtain a fuzzy result.

Fuzzy mathematics can be applied in this field.

The intelligence designed with the logic of fuzzy mathematics can deal with problems that are difficult to determine the result, and the thinking logic is closer to the human brain.

Zhao Yi looked carefully at the knowledge of fuzzy mathematics. Some concepts and logic gave him some new ideas for designing robot programs.

"Let's talk about it when we get back from vacation!"

noon.

Zhao Yi went to lunch alone.

He and Sun Liang usually go out to eat together. The stalls on the street and the small restaurants across the street, regardless of hygiene or unsanitary, are better than the food in the school cafeteria.

Sun Liang went to the winter camp.

Zhao Yi lost his bad friend who made complaints and sarcasm all the way, and he was really not used to it. After finishing his lunch quickly, he returned to the classroom and saw Zhao Linlin rushing in quickly.

"Zhao Yi, it's not good!"

Lin Xiaoqing followed closely behind, shouting continuously, "Zhao Yi! Zhao Yi!"

"what happened?"

The two girls explained out of breath. On the way back from the cafeteria, they met Niu Lianhua. Niu Lianhua told them a "good news". After discussing with Teacher Xue Pinggui, she decided to go to South Island with them during the holiday.

This is definitely not good news!

Lin Xiaoqing and Zhao Linlin pretended to be calm and smiled, and ran back quickly after turning the corner.

"Absolutely, yes, no, yes!"

Zhao Yi took a deep breath, looked at Zhao Linlin immediately, and smiled calmly, "Linlin! Dear Linlin, how about it! You stay at home, I think it's better to go with Xiaoqing, and Aunt Zhao also It doesn't matter, you and..."

Lin Xiaoqing nodded along with her.

Zhao Linlin clenched her teeth, tears were about to fall, with a pitiful look on her face.

Lin Xiaoqing said softly, "How about going with Teacher Niu and Teacher Xue?"

"Absolutely, yes, no, yes!"

"I don't agree 100%! Otherwise I'll go by myself, let's separate, I'm not with them anyway!"

What Zhao Yi said was very firm.

He still remembered the experience of the Mathematical Olympiad exam, when Niu Lianhua and Xue Pinggui were together, it was a kind of torture for others.

Even if he can withstand the pressure of being 'blind' and go on vacation with two teachers by his side?

Is this going on vacation?

Looking at the pitiful Zhao Linlin, Zhao Yi still couldn't bear to leave it behind. It would be strange without Zhao Linlin. He, Lin Xiaoqing and Zhao Hongjuan together... It's too awkward!

Zhao Linlin can play a mediating role.

For example, if Zhao Hongjuan and Lin Xiaoqing sleep in the same room, Zhao Linlin can... ahem!

Yup!

Zhao Yi's eyes lit up suddenly, and he rushed out of the classroom, got on his bike and left the school gate, directly found a travel agency, and asked them to help book a flight ticket and a hotel.

He originally planned to go to the airport to buy a ticket tomorrow, and check the information by the way before choosing a hotel.

No need to choose now!

Just order the expensive one!

Zhao Yi chose a luxury hotel by the sea, which costs more than 2000 yuan a night. Money is not everything, but money is very important. He measured the teacher's salary level and determined that Xue Pinggui and Niu Lianhua were unlikely to live in the same hotel.

That's it.

Whether the hotel is luxurious or not is actually not the key, and it is relatively acceptable. He is not a person who is content with enjoying himself, but he must get rid of Niu Lianhua and Xue Pinggui.

This is the bottom line!

……

School in the afternoon.

Lin Xiaoqing returned home with her schoolbag on her back, and she started talking to Zhao Hongjuan when she got home, "Mom, Teacher Niu said that she also went on vacation, and Teacher Xue, who teaches chemistry, they seem to be in love. Teacher Niu is still worried about Lin Xiaoqing. Lin."

"This is good!"

Zhao Hongjuan's reaction was as expected. She said with surprise, "With two teachers following you, you won't be afraid of delaying your studies. You can also find Teacher Niu and Teacher Xue to make up lessons."

Lin Xiaoqing nodded vigorously, seeming to approve, but said with a frown, "But Zhao Yi has already made reservations for tickets and hotels!"

"what?"

Zhao Hongjuan's focus immediately changed, "This kid is too, as I said, we spend the money ourselves, even if he wants to invite you, I should spend my share!"

"no!"

"I have to give him the money."

Zhao Hongjuan was a little restless, and she suddenly frowned and said, "By the way, your teacher is going too, let Zhao Yi refund the ticket, the hotel is also refunded, let's make a new reservation! Tomorrow, I will book it!"

Lin Xiaoqing quickly shook her head, "I have spent all the money, and it is very expensive to refund. It is said that one third will be deducted. I don't know, but I can't refund anyway, and the air tickets are tight during the Chinese New Year. Maybe you won't be able to buy it if you refund it."

"That's it!"

Zhao Hongjuan hesitated for a long time, then said, "That's fine, I'll talk to Teacher Niu..."

In the end there was no result.

Niu Lianhua heard that Zhao Yi had bought a ticket and booked a hotel, but the tickets for the same day were all gone, so she had to make a mistake one day later.

Hotels are even less likely.

The three of Zhao Yi successfully got rid of Niu Lianhua and Xue Pinggui, and they almost opened a bottle of champagne to celebrate.

Zhao Linlin danced happily.

of course.

When Zhao Hongjuan was around, she definitely had to show regret. This was the case on the departure car. Lin Xiaoqing kept saying, "It's a pity that Teacher Niu didn't go with me!"

"I also told her to make up math."

"And Teacher Xue... What a pity!" She was still smiling as she spoke.

Zhao Yi was sitting next to Lin Xiaoqing, poking her hard with his fingers, which made Lin Xiaoqing's face turn red, and finally stopped talking about Niu Lianhua.

this girl...

Just don't lie!

Since talking about Niu Lianhua with Zhao Hongjuan, Lin Xiaoqing was probably feeling awkward, always afraid that Zhao Hongjuan would see something, and ended up saying it over and over again.

Zhao Hongjuan had already heard it.

Known daughter Moruomu.
