Chapter 320: Prediction of the topic (two/three)

Xu Mang, lying on the bed, listened to the sound of the water, and his brain was thinking about how to explain the next thing to Xiaoman.
moment,
The sound of the water stopped.
Immediately afterwards, the violent airport walked out of the bathroom, then walked to Xu Mang's side, and said softly: "Sleep to the side."
Xu Mang did not hesitate, and quickly lay down on the side in a cold position.
When Xiaoman lay in, Xu Mang leaned forward slowly, hugged her in his arms, and said with a smile: "It's so fragrant, what shower gel do you use?"
"very expensive!"
"The shower gel I wash is several thousand." Yang Xiaoman twisted his body and leaned into Xu Mang's arms as much as possible, with his head clinging to his chest, and whispered: "What's your situation these past few days? Old? Is it such a passion?"
"what?"
"Oh, nothing, just because you are so beautiful." Xu Mang said with a smile, "Xiao Man, do I want to ask you for something?"
"Humph!"
"I knew you were not at ease." Yang Xiaoman gave a white glance and whispered softly: "Say it."
"Can you remember more questions?" Xu Mang said: "I just received a call from Teacher Teng from the Department of Mathematics at Jiangxi University, reminding me that I am the person who made the questions for the Zhejiang Mathematical Olympiad. forget"
"I think let the students of Zhejiang Province feel the types of questions in some international competitions, and see how far the so-called tops in high schools are from the top internationals." Xu Mang said: "It's not like we are not forbidden to engage in Olympiad. How many Olympics?"
Yang Xiaoman shook his head and said silently: "I don't know, we have been miserable at the International Olympiad."
Xu Mang didn’t know much about these things, but he used Douyin to see all kinds of popular science, and then he found a problem. Many people defined the mathematical ability of foreign students as mentally retarded.
of course,
Xu Mang didn't know if the big guys were right, so this time I went to Princeton University to see if the real situation was the same as the so-called big guys on the Internet.
In fact, Xu Mang had an answer to this question long ago, and he couldn't stand his stubborn character.
"Stupid!"
"Have you finished your visa?" Yang Xiaoman asked.
"Ok."
"It's done before you come." Xu Mang said with a smile: "It's settled. Then help me remember some questions, er, remember the most difficult questions."
""
"Can you be a man?" Yang Xiaoman gave a blank look: "The contestants came to the competition, not for your autism."
Xu Mang said awkwardly: "I will experiment. Anyway, I will tell Teacher Teng when the time comes. He is the general manager. I think it is a trend to move the topic closer to internationalization. I have to look forward to it."
"What if it is exploded?" Yang Xiaoman said worriedly.
"It's my shit, I will ask the question." Xu Mang said with a serious face: "Can I ask such a question without the head nod? Without the head nod, can the players do the question?"
""
"You really are not a human!" Yang Xiaoman said helplessly: "You beast!"
Words fall,
A red glow appeared on Xiaoman's pretty face, and he whispered: "Oh beast, when do you do what beasts should do?"
"Sorry!"
"I am a man who is not as good as a beast." Xu Mang said solemnly: "Sleep!"
Yang Xiaoman: Convex (艹艹艹)
this day,
Finally going to Princeton University.
Xu Mang had already applied for the temporary position of teaching assistant and set off with the delegation.
The leading professor's surname is Wu, a good-tempered mathematics professor. During the conversation between Xu Mang and Professor Wu, he discovered that Professor Wu not only has a good temper, but also seems to be a real giant. He knows many Fields Medal winners.
"Ugh"
"In this competition, we were the champions." Professor Wu said: "As a result, you were suspended from the competition, but it was beyond my expectation."
"Isn't this their usual tactic. If you can't beat it, you will be banned." Xu Mang said with a smile: "By the way, Professor Wu, which field of mathematics are you studying?"
"Application problems of partial differential equations, measurement geometry, and probability." Professor Wu said: "Do you have any research on these issues?"
"No!"
"I'm doing physics" Xu Mang shook his head hurriedly, really didn't feel much about mathematics.
at this time,
There is one hour left before takeoff.
Xu Mang simply strolled with Xiaoman in the airport. It was strange to say that no one came to see off the team that represented the country.
"Ugh?"
"What's the situation over there?" Xu Mang pointed to a group of people in the distance and asked curiously: "Did something happen?"
"Maybe a star."
"Don't you see the fierce shooting with your mobile phone?" Yang Xiaoman said: "Only celebrities have this position."
"Oh"
After watching for a few minutes,
Xu Mang observed a man wearing a mask walking to the so-called VIP lounge under the support of him, and then a group of people stood outside the glass wall and took photos with their phones.
"Who is this?"
"Why don't I know?" Xu Mang said with a confused look: "Is he a big star?"
""
"I don't know either. It may be someone who just debuted." Yang Xiaoman shook his head.
Uh
It's just like that,
Not as handsome as 0.1% of this prosperous beauty.
"By the way, why can't we rest in the VIP room?" Xu Mang asked: "We went out to participate in international competitions, and went out to get international honors."
"Don't complain."
"If you are really upset, you can buy the airport." Yang Xiaoman said irritably, "This is reality."
for a long time,
Xu Mang and his party boarded the plane and began their next journey
get off a plane,
Take a ride directly to Princeton City, because the room was booked in advance, and only need to check in with a bag. However, Xu Mang encountered a little trouble because he was temporarily inserted as a teaching assistant and did not have his room.
In the end, he could only live in the same room with Xiaoman. Professor Wu knew that the two were lovers, so he simply opened one eye and closed the other, and the kind reminder was still not forgotten.
"Don't stay up at night, don't do anything unrelated to rest." Professor Wu said seriously.
Xu Mang:? ? ?
Yang Xiaoman:? ? ?
The two soon understood what Professor Wu meant.
This night,
Nothing happened.
The next day,
Princeton University,
For the first time, Xu Mang felt the atmosphere of a famous private research university, but some of the houses were old and felt like more than one hundred years old. Although the classics are quite classic, they feel a little dangerous.
Due to the tight schedule, after Xu Mang attended the opening ceremony as a teaching assistant, he began to help Professor Wu with guessing questions.
The rules of the game are very simple,
There are only two days, and each day there is only one paper, with 50 questions on the paper, a total of 100 questions.
Out of five hundred,
Individual awards will be ranked with the highest scores, and group awards will be ranked by five total points.
at this time,
Xu Mang opened Shi Jie’s notebook in the team, connected to the hotel’s wireless network, and downloaded PUMaC questions for nearly ten years. Together with Professor Wu, he will make a systematic summary of all the questions in the past ten years, and then based on the probability Learn and count the probability of tomorrow's topic.
"According to the experience of previous years, the first ten questions are all free questions, and the last five questions are free propositions. Therefore, the key to winning is the 35 questions in the middle." Professor Wu said: "Geometry and number theory account for 8%. Ten, the algebra problem only occupies 20%."
"and so."
"We strengthen the analysis of geometry and number theory." Professor Wu said: "Xiao Xu, is your number theory good?"
"what?"
"It's okay." Xu Mang nodded and said silently: "But professor, I think the proportion of questions will change drastically this year."
"Oh?"
"Talk about your views." Professor Wu asked curiously.
"I took a closer look at the topics of the past ten years." Xu Mang frowned and said: "The first three years were very targeted, but from the fourth year on, the topics became a little weird until the seventh year. , Began to develop comprehensively."
"Especially last year's topic, the ratio of singularity to comprehensiveness was 37%." Xu Mang said: "I think this year's topic is either 37% or 28%."
"Ok!"
"If it is comprehensive, then it is difficult to follow the topic." Professor Wu said: "I have heard before that the current trend is to cultivate students' comprehensive ability, especially in the field of mathematics."
Xu Mang has also heard of this argument, and he especially believes in this argument, although it violates the so-called single superiority and directly sets its comprehensive benefits.
But in Xu Mang's explanation, science is the basis of human development, and mathematics is the basis of scientific development. Take your own physics, but geometry is really useless, sometimes you must use combination.
noon,
After having lunch with the members of the representative team, Xu Mang stayed in the hotel room, constantly trying the possibility of tomorrow's problem.
then,
Autistic.
"Can the system tell me tomorrow's topic?"
【No】
"Can the system tell me and Xiaoman's children are male or female?"
【can】
Xu Mang: Σ(｀д′ノ)ノ
Damn it!
Your system is very bad!
Can you tell me the of the future child, but can't tell me tomorrow's topic?
Xu Mang's anger, originally a joke, got a heart-piercing pain.
Whoops
This heart is so cold.
In the end, Xu Mang gave up the unwise practice of guessing a hundred questions. In terms of probability, this possibility was too small, so let's rely on their own strength.
of course,
It is impossible to guess the overall situation, but Xu Mang can accurately attack the local area. For example, the last five major topics add up to ten.
If you rely on scientific methods, you can guess three of ten questions, or even more questions.
"Let's work!"
When Yang Xiaoman came back from shopping ~EbookFREE.me~, he saw Xu Mang lying in front of the computer and screaming, he could not help showing a look of helplessness.
"It's estimated that the account has been blocked again" Yang Xiaoman sighed: "Playing a game is so good."
Taking a blanket and preparing to put it on Xu Mang's body, he immediately saw ten math problems on the laptop display.
"Ugh?"
"what is this?"
Yang Xiaoman was stunned for a moment, and carefully observed these ten math problems. In fact, they weren't any math problems, because there were no numbers on them, they were pure words.
The first question of the big question,
The combination of number theory and geometry appears with high probability
Yang Xiaoman: (￣△￣;)
What the hell?
When you are a forecaster?
