Shen Yun spoke eloquently, and mathematical symbols came out of his mouth, as simple as telling a story.

The students who were still sitting in the classroom, except for being dumbfounded, seemed to be unable to show a suitable expression to face all this in front of them.

And Shen Yun has just finished talking about the first plan,

"The second model is the ring search model. The search area is divided into two congruent parts, which are demarcated by the short-side midpoint line. Search for a part of every ten people in the same way, because of the symmetry of the problem, we only look at the first half. ”

Shen Yun's thinking became more and more thorough, and the speed was so fast for a while that some students who wanted to take notes could only look at "Shen" and sigh.

In ten minutes, Shen Yun dictated all the modeling processes. A "finished answering" instantly detonated a round of warm applause in the classroom.

At this time, the instructor standing on the podium also looked at Shen Yun with a look of relief: "Good, very good." Both models are based on the idea of avoiding repetitive search and non-search travel. Shen Yun, your answer is perfect. ”

After signaling Shen Yun to sit down, the instructor turned the question over, and the answer that appeared next was the roundabout search model that Shen Yun said before. Pointing to this question, the instructor nodded and praised: "The two methods have their own advantages and disadvantages, you can discuss with Shen Yun after class the kind that has not been written." ”

After finishing speaking, he began to operate the next question on the computer, and at this time, Fang Han and the three of them gave Shen Yun a thumbs up at the same time.

In a big class, the instructor asked Shen Yun three mathematical modeling problems one after another. And every question, Shen Yun gave a perfect answer in a look of envy, jealousy and hatred.

At nine fifty, the bell rang for the end of class, and the instructor did not walk out of the classroom as soon as possible, but beckoned to Shen Yun: "Shen Yun, you come with me." ”

Shen Yun was stunned, and was instantly pushed up by Fang Han and a few people: "Why are you stunned, come over quickly, the instructor will call you." Remember, after you're done, go directly to Sanjiao 203. The political and ideological work of the army in the next class will be taken there. ”

Nodding, Shen Yun quickly packed up his things and walked out of the classroom with the envious eyes of this group of majors and captains. And at this time, Zhou Jin also shouted at the right time: "Hurry up and gather downstairs, class is going to be at ten o'clock, what are you rubbing?" ”

Only then did the big guy remember the time-critical problem.

Shen Yun followed the instructor to the instructor's lounge not far away, where there were three people drinking tea and chatting.

"Instructor Tang, what's wrong with this student?" Looking at the two people who walked in, one of them asked with a slight smile. Even if it is a cadet, it is still possible to make small movements in class. Therefore, this person thought that Shen Yun had committed this thing.

"Haha, it's okay, it's just something I want to talk to the young man. Come, Shen Yun, drink some water. You still have class at 10:10, so I'll make a long story short. At the end of this month, there was a mathematical modeling competition for military cadets in military academies across the country. ”

"Huh?"

Shen Yun was dumbfounded this time. He never expected that this instructor would actually mention something about the game.

Seeing Shen Yun's surprise, the instructor also patiently explained: "This competition, there are still difficulties. The two questions I just came up with in class are the test questions of previous competitions. ”

Your answer was not only very standard and prompt, but it also came up with new ideas. I'm afraid that before this, you already have an in-depth understanding and learning of mathematical modeling. So I'd like to ask for your opinion and sign you up. ”

Shen Yun said very helplessly: "Report to the instructor, I have no opinion. ”

No opinion, naturally, is a good thing. Instructor Tang nodded with a smile: "Since this is the case, it will be easy to do." In this way, there will be my class the day after tomorrow, and I will bring the registration form when the time comes. Once you have filled it out, you can go to the mathematics department in the afternoon to find me. ”

Shen Yun nodded, saluted, and then walked out of the lounge.

And at this time, suddenly a teacher exclaimed: "Old Tang, you just said that this young man's name is Shen Yun?" ”

"yes, what's wrong?" Instructor Tang drank the tea beautifully, and was thinking that he had found a talent: "This name looks quite unfamiliar, I have been teaching students for a month, and I haven't recognized him yet." ”

Instructor Tang's words instantly caused this instructor to laugh: "You recognize the ghost, this student only came to our academy the day before yesterday, and only officially entered the school yesterday." If I remember correctly, this should have been his second lesson. ”

"What?"

Instructor Tang exclaimed, looking very strange in the eyes of the other two instructors. Isn't it just a student, who needs to make such a fuss.

"You don't know, according to that, this Shen Yun has never taken my class at all. But today, when it comes to mathematical modeling, he actually dictated and did three questions correctly. This young man has definitely studied specifically before. ”

Hearing Instructor Tang's words, the other two instructors showed a look of understanding, while the instructor who had told Shen Yun about his origin before had a calm expression.

"What's this, this guy is still the first guy to finish all the top difficulty exam papers. At first, Dean Ding told me that I didn't believe it yet, but now, I have to believe it if I don't believe it. Besides, whether you have learned it or not, just look at his materials. ”

Shen Yun, who didn't know that four more instructors had begun to be curious about him, was sitting in Sanjiao 203 at this time, looking at the army's political and ideological work notes handed over by Fang Han, and was dumbfounded for a while.

Looking at his dull gaze, Fang Han felt that it was probably the depth of this course that made him afraid. With a reassuring smile, Fang Han said: "Actually, you don't have to worry, you must know that although this course is relatively deep, there is only one class per week, that is to say, I have only taken four classes so far, and it is easy to make up for it." ”

However, the reason why Shen Yun was really sluggish was not this at all.

If several leaders of Shen Yun's old army got this note, they would definitely be surprised, and then said: ", Shen Yun's things have actually become the teaching materials of the military academy's political class." ”

That's right, what is written in the notes is the first part of the paper that Shen Yun wrote. As soon as the experts engaged in the study of military and political ideology diverged, they became like this -- the phrase "obey the party's command" was actually taught here without finishing four lectures.

I have to say that Shen Yun's heart at this time, when he was extremely excited, couldn't help but feel a little bitter. The things described in it are so profound that it is not easy to understand and comprehend.

Is this the idea that the author of the legend does not understand his own article?
