The group pet sister fell off again

Chapter 173
P (polynomial algorithm) problem vs. NP (non-polynomial algorithm) (also from one of the top ten problems in the world)

At the moment when he saw the topic, Zhang Jiaming's complexion changed a little. This topic was completely out of his area of ​​expertise, so without any hesitation, Zhang Jiaming resolutely admitted defeat.

Zhang Jiaming ended dejectedly, and Quan Jiuli directly replaced him on the stage, because it was originally arranged that Quan Jiuli would not appear on stage, to preserve his strength and hide Quan Jiuli's trump card.

But unexpectedly, there was an accident. None of the members of the youth group sent by country Z had come into contact with the questions this time, except Quan Jiuli.

People in the youth group are either not good at this kind of topic, or they have been exposed to it, but they are not very proficient, so in order to ensure the victory of the game, they can only send Quan Jiuli to play.

As soon as Quan Jiuli came on stage, she didn't say anything, but just came to the whiteboard and began to write the answer.

The man was a little shocked when he saw the answer given by Quan Jiuli. These were the questions assigned by the professors of their college when they left the college. If this set of questions were not because of today's competition, they would never have come up with it. I didn't expect today On the field, someone actually solved it with a method that was simpler than the professor's.

Quan Jiuli looked at the shocked look on the man's face after explaining the question, and couldn't bear it. This question was left behind by her before leaving Y Country Academy. She didn't expect it to be used as a competition question now. It's really not I am too strong, but the other party actually releases water.

"How can you work out this problem." (How can you work out this problem.)
"Is this a difficult question?" (Is this a difficult question?)

"This is the question left by the honorary principal of our Y country. Do you think it is difficult." (This is the question left by the honorary principal of our Y country. Do you think it is difficult.)
"Honorary president! When did you become an honorary principal? Why didn't I know." (Honorary president! When did you become an honorary principal? Why didn't I know.)
The man frowned and said: "Our honorary president of Y, what do you care, you tell me how you solve this problem." question.)
"No comment. Now that I've worked out your problem, it's my turn to work it out." (No comment, now that I've worked out your problem, it's my turn to work it out.)
While talking, Quan Jiuli wrote down the topic on the whiteboard

Yang-Mills Existence and Quality Gap
Seeing this question, the man also admitted defeat, after all, he didn't answer it by himself, and seeing that Quan Jiuli easily solved their professor's question just now, he knew that he was destined to be difficult than Quan Jiuli.

The host looked at this woman who had finished two competitions, and fell into a deep silence. What happened to this world? Why was the girl named Quan Jiuli turned the tide in the last cultural and art competition? This girl named Quan Jiuli turned the tide, wouldn't something like this happen in every next match!

I have to say that although the host thought quite far, he was right.

"All right, let's congratulate the representative of Z on his re-entry, and then let's welcome the representative of M to the stage."
The person representing country M was Quan Moxie. Looking at Quan Moxie, Quan Jiuli said, "I won't show mercy."

"I won't either, let me see your ability."

The shameful rock-paper-scissors began. Quan Moxie naturally doted on his sister, so of course he let the water go.

Of course, the strength of our boss Quan doesn't need to be released at all, so the first chance to ask questions fell to Quan Jiuli.

Out of respect for his brother, Quan Jiuli asked a new question.

Existence and Smoothness of Navier-Stokes Equation

Quan Moxie looked at the topic on the whiteboard, and the shock in his eyes became deeper and deeper. Most people who can write this kind of topic would think that it was written by a senior who has been teaching for at least ten years, but the truth is that It was written by a child who was only 16 years old. How can this not be shocking.

Quan Moxie really conceded defeat, and even went off the field to communicate with the representatives of the elder group of country M before giving up the rest of the game.

Because today's match let them know that Quan Jiuli can only be friends with each other, not enemies.

　The writing in this one is a bit simple, because it is necessary to quickly advance the three departures and lose the horse, so the writing is relatively simple. You can just look at the titles in the middle of this one. Don’t delve into it. I can't even read it.
