"This is...Lagrange Multiplier method!"
"That's right, it's Lagrange. I didn't expect this question to be so intensive!"
"The perfect solution is flawless!"
"What a genius brain that I think of such a beautiful and straightforward way of thinking."
After reading the new solution given by Gu Lu, the team leaders from all countries were excited.
One by one, they looked at Gu Lu beside Chairman Andre with a marvelous look.
Thirteen lines!
Gu Lu only used thirteen lines of formula to easily solve this algebra problem.
The standard answer given uses twenty-eight lines of formula.
More importantly, Gu Lu used the Lagrange multiplier method to solve this problem.
Introducing Lagrange Multiplier method is a very clever idea.
It is also an important reason why the leaders of various countries exclaimed their surprises repeatedly.
Because, if you use Lagrange multiplier method to solve this algebraic problem, the difficulty of this question will not even reach one-third of the original difficulty.
In other words, the emergence of Gu Lu's solution made a high-difficulty problem worse than some simple and difficult IMO questions.
Lagrange The introduction of multiplier method is indeed a matter of the gods in this set of solutions.
It’s not Lagrange. The multiplier method is so difficult, but before this, the leaders of various countries had never thought that this algebra problem could be solved in this way.
Genius’s ideas, perfect solution!
Team leaders from all countries admire Gu Lu very much.
Chairman Andrei turned his head to look at Gu Lu with curiosity, and an intriguing smile appeared on the corner of his mouth.
He glanced at everyone, "Do you have any opinions on Team Leader Gu's solution?"
Everyone smiled bitterly and waved their hands.
Gu Lu's solution is already more standard than the standard answer, what else can they have?
But at this time, the leader of the American team raised his hand and signaled, "Chairman, I have some different views."
"Please say it." Chairman Andrei nodded.
"Of course, I'm not the solution shown by Team Leader Gu." Afraid of being misunderstood by everyone, the team Leader of the United States explained first, and then said, "What I want to say is about this question itself."
"From the solution provided by Team Leader Gu, we can see that the difficulty coefficient of this algebraic problem is obviously overestimated by us! As long as we use the Lagrange multiplier method, the difficulty of this question is even worse than the number theory of the first question."
"I think it is obviously inappropriate to put this question in the second question! So, I suggest that you remove this question and select the topic again!"
Re-select topics!
When the American team leader said these four words, the entire conference room was boiling again.
If the test questions have been determined, re-select the topic.
This situation has not happened in the IMO field for more than 20 years!
But today, it is staged again because of a problem solution provided by Gu Lu.
Regardless of whether this algebra problem was replaced in the end, this scene will definitely be recorded in the history of IMO development.
The name of Gu Lu will also be recorded.
On one side of the conference table, Park Changqu was completely stunned.
The current development of the situation has completely exceeded his expectations.
Originally, he wanted to compete with the solution provided by Gu Lu and the solution he just showed on stage.
But now it seems that there is no need for that.
As soon as Gu Lu took out his solution, everyone forced to consider re-choosing the topic.
And what about his solution?
It seems that even a small wave has not been turned up.
In an instant, the right and wrong are immediately judged.
Kakka--
Park Changqu felt that his self-esteem was shattering little by little.
I prepared for six years, but when I really faced Gu Lu again, I was still completely crushed.
Just like the time six years ago.
In the conference room, the noise continued.
The team leaders of several countries led by the United States believe that the second question should be removed from the IMO topic list and the topic should be selected again.
But there are also a group of countries that disagree.
They believe that Gu Lu's solution using Lagrange multiplier method is hard to imagine, so there is no problem of being too simple.
Both sides held their own opinions and quarreled in the conference room.
"Team Leader Gu, come and evaluate the reason. Is it difficult for ordinary people to think of this solution?" A team leader of a country who opposed the IMO list of opinions on the topic, pulled Gu Lu among the crowd. "Did you think of this solution after you have spent a lot of effort?"
As the culprit of the incident, Gu Lu was stared at by a pair of eyes.
Gu Lu smiled helplessly and told the truth, "It's okay. Actually... it doesn't take much time."
Everyone in the audience: "????"
Didn’t it mean that Chinese people regard modesty as their virtue? But Team Leader Gu…what is your modesty?
With the audience's speechless look on their faces, Gu Lu shrugged innocently.
These days, I don’t even want to tell the truth.
At that time, at the first glance of this question, Gu Lu subconsciously came up with this solution in his mind.
That's why I felt that the complicated standard answers were shown on the screen and it was a bit difficult to understand.
After nearly ten minutes of discussion, Chairman Andre finally decided not to make a re-choice and continued to use the three selected questions.
After all, it is impossible for every student to be as perverted as Gu Lu, and he can think of it using the Lagrange multiplier method to solve the algebra problem.
After discussing all this, it was already past eleven o'clock.
Chairman Andrei handed the three questions to the assistant and asked the assistant to arrange for someone to translate the test questions into languages of various countries.
In order to avoid the team leader leaking questions, the activity areas of more than 100 team leaders from various countries have been temporarily restricted to this office building.
It was not until the candidates entered the venue in the afternoon that everyone could move freely.
…………
Gu Lu returned to the seat in the conference room with a faint smile on his face. He saw that the leader Park Changqu was lowering his head, and his face was gloomy and fell into autism.
Gu Lu smiled and said, "Captain Park, don't you go down and have lunch together?"
"No." Park Changqu, who was autistic, spoke in a muffled voice, "I feel uncomfortable, I don't want to eat."
"Uh... well, I'll go down first."
"Gu Lu... wait!" Park Changqu called Gu Lu, looked up, and looked firm, "For this IMO, we South Korea will definitely win the first place! Your Chinese team cannot win!"
Gu Lu shrugged and turned his head to leave, "Ha, just be as good as you like, just be happy."
Some things are not enough to just say them.
Gu Lu is also determined to win the championship of this IMO team competition!
Looking at Gu Lu's departure back, Park Changqu was like a punching cotton, and the fighting spirit that he barely supported suddenly disappeared.
"Champion, I will definitely stay in our South Korea!" Park Changqu clenched his fists hard.
It's not just China and South Korea.
Many powerful competitive powers have all the goals this time to be for the championship.
After all, even the major countries in Europe and the United States are very jealous.
Not to mention China, South Korea, and island countries that have not joined CERN.
It can be predicted that this IMO will definitely be the most tragic battle.
Many countries are at the end of their elite forces and are moving towards the championship trophy.
