Chapter 283 BGI: Is this rejection or acceptance?
The format of the defense is actually very simple. The contestants stand on the podium, the computer is connected to the projector, and they give their thoughts on a difficult problem within a given time. And try to improve the degree of completion.
For the sake of fairness, everyone only has fifteen minutes. Those who have finished their defense will leave the examination room through another door, leave the teaching building and wait for the afternoon closing ceremony to announce the list of participants for the international competition.
Perhaps the organizing committee just went by ranking to save trouble?
It doesn’t matter, first or last, Li Yan has no pressure.
"Let's get started, Li Yan. There is a question on the table. Please tell us your thinking process." Du De showed a rare kind expression on his stern face, "Don't be too rigorous, talk more, so that we can I see your thoughts.”
“Even some tentative ideas.” The executive director wore a formal suit today, and his temperament was very different from last night.
"Okay." Li Yan said and clicked on the question.
It’s complicated at first glance, but it’s still complicated at second glance.
There is no smart little character who likes to compose poems or play games. This question has no nonsense at all and is very abstract.
It's almost like a math problem.
After watching for ten seconds, Li Yan spoke:
"The meaning of the question should be that given the values of N non-leaf nodes and M leaf nodes, the leaf nodes have The initial value is 0 or 1. If there are becomes 0), and then asked how many ways to set parameters for non-leaf nodes so that the root node value is 1 and take the value of the number required by the question."
A few judges in the audience smiled. nod.
“This value is interesting.” Li Yan also smiled.
Then he immediately frowned and started thinking.
Three minutes later, he still didn’t say a word.
Dude gave the executive director a look, and the director was about to remind Li Yan that he could talk about his ideas.
Suddenly I heard Li Yan say "Hey".
“This problem seems to be very unsolvable, because the number interval is not related to the shape of the tree, and we cannot use any data deconstruction on the tree to solve this problem.”
The judges nodded again.
"And I think the judges will not use an unsolvable problem to test whether I can see that there is no solution... This is really boring. This also means that this problem has a solution."< br>
I seem to be talking nonsense?
"I made a bold guess. To have a solution to this problem, it is best for each non-leaf node to contribute independently to the answer. The proof here is not difficult, so I will omit it."
Judge They were stunned, and the executive director picked up the phone again.
"The main thing is that I don't have enough time, so I won't do some simple proofs." Li Yan spoke very quickly and pressed the director's hand holding the microphone, "Confirmed this, the follow-up is not difficult, please wait a moment Wait.”
Then he opened the programming software on the computer desktop.
"Huh?" Dude opened his eyes wide.
Li Yan actually started to write the code directly with his hands, and the speed was jaw-dropping.
The hand speed was so fast that his mouth couldn't keep up - it was really hard to pronounce in the first place, and he had to convert it in his mind, so he simply shut up and concentrated on coding.
The executive originally picked up the microphone three times to emphasize the time issue, but was stopped by Du De.
A genius performance should not be a disappointment, but should be willful.
"I won't say some things at the same time. There is still some time to finish coding."
About eight minutes passed, and Li Yan stopped.
“As above, omitting the conjecture and proof, just use the line segment tree to maintain the total answer after the tree DP. The time is limited, there are no optimization details, it is probably movable, and the time complexity is also marked.”< br>
The judges watched for a while, and some of the frowning ones relaxed, while a few of the pensive ones began to nod frequently.
Then the eyes randomly crossed each other, and finally converged on Dude.
Dude took the lead in applauding, and the others politely followed suit, maintaining the integrity of the judges.
"Wonderful." Chairman Du said loudly, "You are actually a first-year junior high school student. This is unbelievable to me. Based on your performance in the national competition this year, I dare say that after so many years as chairman, Among the talented young people I have ever seen, no one can compare with you!”
Now that the tone has been set, the applause is loud.
But when the nine geniuses separated by a wall heard the applause, they felt very complicated.
Li Yan, who had just left the examination room, turned the corner and saw two people with name tags in suits and ties, looking a little anxious.
They were anxious to see Li Yan.
So Li Da Yingying, who just now was thinking about finishing his defense and going to visit the school, was invited by this man and woman to the cafe next to the cafeteria.
In 2009, a high school actually had a coffee shop!
But in fact, there is a beverage area next to the cafeteria. It is used as a study room and has some small stalls such as fruit juice and coffee.
This is now called the "Signing Negotiation Room".
What we are talking about is naturally the matter of high school geniuses signing contracts with prestigious universities in advance.
There is only one possible identity of these two people that could allow Li Yan to follow them all the way:
The signing officer of Hua Xia University - actually the teacher of the admissions office.
As soon as he entered the house, Li Yan noticed two young men in blue suits beating their chests.
On the table is "Hua Xia University of Science and Technology". The second-ranked university in the country, its strength in science and engineering is not inferior to BGI.
If you hesitate, you will lose. Brothers, it doesn’t feel good to have your beard cut off.
Just the suits and brand names in this room... no matter how you look at it, it feels like a real estate sales conference.
"Hello, classmate Li Yan, I am Director Ma from the Admissions Office of Huaxia University. We have all seen your wonderful performance in this competition..."
A wave of expected rainbow farts .
When they met for the first time, Li Yan decided to be polite, so she did not interrupt.
"To be honest with you, several of our universities have held internal meetings just for you." Director Ma is a thin woman who looks to be in her forties, with a pleasant voice and a gentle tone. "The main discussion is, That’s your status as a freshman in junior high school.”
“You’re about to be in the second year of junior high school.” Li Yan replied.
Director Ma smiled and said, "Yes, based on your performance, you are completely qualified for special recruitment. No, it should be said that your performance is enough for our major universities to recruit you with the utmost sincerity."
"But I'm in the first grade of junior high school." Li Yan added.
"Yes, BGI has never recruited a junior high school student." Director Ma lowered his voice, "We are considering implementing an outstanding genius program, but the most radical plan is to expand the enrollment range Expanded to the first year of high school."
At this point, Director Ma looked impressed, "But you are in the first year of junior high school."
"Are you worried about hurting Zhongyong?" Li Yan asked. road.
"Of course it's impossible," Director Ma laughed. "You can rest assured about this. BGI has never been so worried. Even our President Cai is full of praise for your genius. But to be honest, talent cultivation cannot Urgent, you have just finished your first year of junior high school, and we will also consider your experience...BGI will give you two options.”
Finally, we get to the point.
“The first one is to continue to study in the second grade of junior high school in New Taipei No. 1 Middle School next year, and then go to the High School Affiliated to Huada for one year of high school to get used to it, and choose a professional direction to study for a 3+2+3 bachelor’s and master’s degree at Huada. Bo Talent Training Class.”
Li Yan’s face was expressionless.
Director Ma did not expect this reaction, and suddenly became a little nervous, "The second one is more radical. He will go directly to the High School Affiliated to BGI next year to attend high school. After two years of study, he will join the 'Outstanding Youth' organization organized by BGI. 'Select and determine the professional direction to attend the excellent class for cultivating special talents. ”
Li Yan was still expressionless.
"Li Yan, do you have any ideas?"
"That's it?"
Five thunders struck the brains of the two BGI admissions office teachers. Come on.
Director Ma, who was full of emotional intelligence, forced a smile and responded, "Classmate Li Yan, don't get me wrong, these two plans have no intention of continuing to examine you. It's just that after all, learning is different at different stages, and cultivating talents is different. Be patient and dig into the professional direction you really want to develop - especially for a rare all-rounder like you.”
"Yes, I know, Director Ma, doesn't BGI have a junior class?"
Director Ma didn't expect that Li Yan would be interested in this thing, so he explained: "That one was for outstanding junior high school students. The initial version of the training plan is meaningless. Due to your outstanding performance, the school leaders have continued to improve the specifications. There is no final version yet. "
"Can it be customized? "
Director Ma is already a little confused, "You say."
"First, set up a teaching center in New Taipei Middle School, and I want to stay in New Taipei to study. Second, give it to the juvenile class... forget it , it is up to you whether others will give it to you, I will only tell you my demands, and give me sufficient learning freedom and learning resources.”
"If you set up a point, you can. There are different tendencies for centralized teaching and point-based teaching." Director Ma frowned, "Learning resources, we must provide better teachers than the top high schools, but you choose to stay in As for New Taipei, the hardware facilities can only be found in New Taipei Middle School."
"It's okay."
"What does freedom of study mean?"
"Like. I am like this now.”
Being able to be the director of the admissions office, Teacher Ma is certainly no ordinary person. She also has a thorough understanding of Li Yan’s situation in junior high school, so she understands what Li Yan is talking about— —
A privilege called freedom.
“I can promise you on my own behalf, but it depends on the final plan of the junior class of BGI...”
“I understand this, just wait for the specific arrangements of the junior class. Right.”
“But I don’t quite understand. If you take the junior class route, you will have to spend an extra year in middle school. Wouldn’t it be better to enter BGI earlier?”
"I also have my own considerations, Teacher Ma." Li Yan said with a smile, "That means we have reached a consensus, thank you."
As he said this, he shook hands with two teachers from the admissions office of the University of Washington, then waved and left without taking away a single cloud.
Seeing Li Yan shaking hands with a smile, people from other universities thought that the dust had settled and shook their heads.
"Who calls me BGI" is written all over my face.
The young man next to Director Ma looked at the signing agreement on the table, pointed at the blank signature column and asked:
"Director... does this count as rejecting us or agreeing to us? ”
Director Ma frowned and pondered for a long time, then tapped his fingers on the table and said slowly:
“This kid is so interesting.”
