Let's go!

After the crowd, a piece of apple that Isabella had just forked with her fork fell to the ground.

She stared blankly ahead, her beautiful eyes widened, and she exclaimed, "Blair!"

"It's him ......"

In the crowd, a hint of surprise appeared on Alice's face, the second-year magic genius, the first author of Blair's theorem, the mystery of Raus, and his move to stand up at this moment......

All this shows that this junior has enough reasons worthy of her attention.

The sudden situation made Britney also stunned in place, but then her face changed, and she hurriedly said: "Blair......"

As soon as she said her words, she was interrupted by another person, and Debbie looked at the spoiler in front of her and said angrily, "Who are you!"

"I'm a student of Teacher Britney, my name is Blair. Chen Luo looked at the woman in front of him and said calmly: "Teacher Britney's time is precious, if it is just a problem of this level, there is no need to trouble my teacher, I will answer your doubts instead of her." ”

The purpose of the academic salon is to exchange ideas among scholars.

It is not uncommon for mathematicians to gather together to discuss problems and exchange ideas, and it is not uncommon for beginners to ask university scholars for advice.

However, the number of scholars is scarce and their energy is limited, and it is impossible to solve everyone's problems, so their disciples will answer questions in their place.

Or maybe the disciples felt that some of the questions were too simple to be worth bothering their teachers.

The young man, Blair, apparently for the second reason.

At this time, everyone present had only one evaluation of him at the moment.

Arrogant!

It's so arrogant!

What does it mean to "just a problem of this degree", doesn't he know that it is a problem of this degree that has stumped several university scholars at the headquarters of the Royal Capital Mathematical Association, and all the mathematical researchers in the Kingdom of Nolan, "a problem of this degree", including them, and everyone present has not been able to give an answer!

Behind, an old man looked at Chen Luo, frowned slightly, and said, "Which little guy is this, I don't know how thick the sky ......?"

Calvin looked at Chen Luo, his face showed a strange expression, and he said in a low voice: "Look at it, maybe this little guy really has the potential to create miracles......

Britney looked at Chen Luo, with a hint of worry in her eyes, Chen Luo smiled at her and said, "You sit here for a while, I'll be fine soon." ”

After speaking, he looked at Debbie and the others and said, "Can you let me go?"

Debbie glanced at Chen Luo coldly and gave way to an empty table. She didn't believe that the little-known Britney Spears could solve the problem of the Nine Bridges of the Royal Capital, let alone her young student who was not talkative, this problem had stumped countless mathematicians and even university scholars, could he be able to compete with the entire mathematical community by himself?

Chen Luo was already surrounded by people, and the issue of the Nine Bridges of the Royal Capital had been circulating in Yabo City for some time, and almost everyone present had studied it, but there was no result.

If you can get the answer to the question of Nine Bridges here tonight, then it will be the biggest takeaway from attending the academic salon tonight.

Although this sounds a bit unbelievable, the problem that stumps all university scholars can be solved by the disciple of a rookie in mathematics------ but isn't that the charm of mathematics?

The goddess of wisdom is not just, and all mathematical researchers must admit that talent is such a thing, seemingly ethereal, but it really exists.

The results of their life's research may really not be as good as what others do casually......

Under the starry sky of mathematics, countless geniuses have been born out of thin air, illuminating the entire night sky with the power of one person.

Chen Luo, who had become the focus of the audience, picked up the quill unhurriedly and drew a strange figure on the paper.

The so-called Nine Bridges of the Royal Capital and the "Seven Bridges of Königsberg" that Chen Luo is familiar with are both problems of one stroke.

The problem of the "Seven Bridges of Königsberg" is one of the famous classical mathematical problems of the 18th century.

The problem of the seven bridges is described in this way: in a park in Königsberg, there are seven bridges connecting two islands in a certain river to the riverbank, and one day, a boring idea arises in the mind of a passer-by: is it possible to start from any of these four landmasses, pass through each bridge exactly once, and then return to the starting point?

Although there are two more bridges than the "Königsberg Seven Bridges", the problem of the Nine Bridges of the Royal Capital is essentially a one-stroke problem.

The Seven Bridges problem stumped many mathematicians in the 18th century, and it was Euler, one of the greatest mathematicians in history, who finally solved it.

Thinking of Euler, Chen Luo couldn't help but think of Euler's teacher Bernoulli, and Bernoulli's teacher was called Leibniz.

Euler also had a student named Lagrange, who later adopted a disciple named Cauchy------ names that were once a nightmare for Chen Luo in college.

Until now, he could not forget the shadows that were once dominated by these people.

Euler not only solved the seven-bridge problem, but also created a new branch of mathematics ------ graph theory and geometric topology, and at the same time, he summarized and categorized such problems, and obtained and proved several conclusions about a wider range of strokes, which are often called "Euler's theorem".

Since then, the problem that has plagued countless great mathematicians has become a scoring problem for the Primary School Olympiad.

Chen Luo has no interest in teaching these people the Primary School Olympiad, but he must take care of Teacher Britney's face.

Putting away these thoughts, he looked back at the graphics on the paper, although the problem of one stroke is simple, but it involves an important mathematical idea, abstracting a complex practical problem into a suitable mathematical model, this kind of mathematical thought, in the eighteenth century, began to sprout, according to the level of mathematical development in this world, to produce this modern mathematical thought, probably have to wait hundreds of thousands of years.

Chen Luo pointed to the figure on the paper and said: "The problem of nine bridges can be expressed in this way, we consider each piece of land as a point, and the bridge connecting the two pieces of land is represented by a line, and the figure on the paper is obtained. ”

A scholar who was closest to Chen Luo had just seen the figure he had drawn on paper, and when he was confused, he heard his explanation, and suddenly realized, and couldn't help but say: "It is actually possible to simplify complex practical problems into geometric figures in this way...... What a brilliant thought!"

The surrounding scholars had also studied the Nine Bridges problem, and after they crowded to the table, they looked down at Chen Luo's figure, and immediately realized that this was a simplification of the Nine Bridges problem.

In a short period of time, most of the people around them put away their contempt for the young man in front of them.

Whether he can solve the Nine Bridges problem or not, this subtle idea alone will allow him to win the respect of everyone.

This has pushed the Nine Bridges issue a big step forward.

Douglas's face was calm, and he couldn't see his emotions, while Debbie's face became a little unpleasant, glanced at Chen Luo, and said, "You ......"

"Don't talk yet. As soon as she spoke, she was interrupted by someone beside her, who didn't even look at Debbie, looked at Chen Luo with inquiring eyes, and said, "Please continue." ”

Debbie's face turned red, but she didn't dare to say anything, the other party was a famous scholar in the city of Apo, and her status was higher than her elders.

Chen Luo nodded slightly to the scholar and continued, "Obviously, in addition to the beginning and end, when someone enters a piece of land from one bridge, he must leave from another bridge, so the number of bridges connecting each piece of land to other lands must be an even number, except for the beginning and end...... On this graph, the points connected by odd line segments are called singularities, and the points connected by even line segments are called even points......"

Teacher Britney stood behind Chen Luo, with a sudden look on her face, and muttered: "If you want to start from the starting point and finally return to the starting point, then you must reach all the points and leave all the points, so only if all the points are all even points, can the Nine Bridges problem ......be solved."

As Ms. Britney said. Chen Luo turned around, looked at Teacher Britney with a smile, and said: "The problem of the Nine Bridges in the Imperial Capital, there is obviously a singularity, a land that can only enter and cannot leave, therefore, there is no way for people to start from the starting point and eventually return to the starting point, and pass through all the Nine Bridges without repeating ......."

"To sum up, there is no solution to the problem of the Nine Bridges in the imperial capital. ”

After Chen Luo finished speaking, he looked at Debbie and the others and asked, "Do you understand?"
