Chapter 23 This is a genius!
"Summary key points: 1. For the problem of one-completion flow record method, the cost prices of most non-discounted commodities in Annex 1 and Annex 2 are missing. Note: 783524 missing data can be solved by two methods. a. System product ID traversal is not The lack of cost price historical flow fills in the missing part of 71.46, historical data query X, prior experience 20%-40%; in addition, generate a random commodity profit rate (0.2-0.4), and carry out reverse deduction.”

"2. Through the known variables in Appendix 3 → product discount rate, profit rate, discount responsiveness indicators → coarse-grained results → final daily discount intensity."

"3. For question 3, use iterative weighted least squares method → ​​discounts are positively correlated with sales, and discounts are negatively correlated with profit margins."

"4. Analysis of price elasticity of demand."

"5. Symbol description:"

"6. Formula list:"

"7. Simple chart:"

……

I haven't written much content on the manuscript paper, but simply wrote some ideas for solving the problem according to the requirements given by the topic.

As the head coach of this mathematics competition, Zhou Jingxue also recognized at a glance that this was the train of thought for the first question in the question bank of the preliminary contest. There seemed to be nothing wrong with it, but how could the train of thought be so clear?And how do the matching mathematical formulas next to them match so well?Even the pictures drawn by hand are the same as the software?
If it weren't for the fact that the ink on the last picture hadn't dried completely, Zhou Jingxue would have suspected that this was a reference answer given.Although he briefly browsed through the questions just now, and roughly passed the solution to each question in his mind, obviously he couldn't sum up the question so concisely and clearly.Not to mention the ability to draw freehand.

After Zhou Jingxue scanned the manuscript paper, he subconsciously checked the time, and it was only 8:49.He still remembered that at 7:33, Ning Qing just started to open the question bank, and it took nearly an hour to study all the questions. About 10 minutes ago, he was still searching for the biographical information of two celebrities on the Internet.Zhou Jingxue believed even more that other group members were probably still conducting group discussions at this time, while Ning Qing had already begun to directly formulate the problem-solving ideas clearly and clearly.

Not to mention high school students, even college students probably don't have this efficiency.

Zhou Jingxue swallowed subconsciously, for a moment he didn't know what to say, he was indeed doing a serious job, and he did it better than he imagined.

The manuscript paper was put back on the table by him, and he was a little hopeful when he spoke: "Um, that... By the way, Ning Qing, you are used to listening to music when thinking about problems, right?"

Ning Qing nodded and asked, "Yes, why is it not allowed in the competition rules?"

Zhou Jingxue quickly said: "That's not true, it's just that the sound insulation here is not very good, and I'm afraid it will interfere with other students' thinking. How about this, I'll change you to a computer with a sound card and give you a pair of headphones. Do you think it will work?"

Ning Qing thought for a while, then looked at the only girl in the group, and said, "Well, Liu Xiaohan, why don't you go and record the melody just now? I think listening to this melody is very touching."

The girl blinked her eyes, looked away from Zhou Jingxue, who had a sudden change in temper, looked at Ning Qing and asked, "How many times do you think I recorded it? Just now I played it three times completely, and made some variations each time." .”

This really touched Ning Qing's knowledge blind spot. He didn't quite understand what variation meant, so he shrugged and said, "Actually, it's all fine, as long as the main theme is not bad. I just listen to the melody. Thinking becomes clearer.”

Liu Xiaowan nodded and said: "Then it's better to do this. I will go to the music classroom and record it for you with violin, piano, flute and harmonica, and then how about you listen to it on a loop for the next two days? If you hurry up, it should be at noon. We can finish recording before eating."

Ning Qing immediately nodded and said, "That's a good suggestion. I just go online again in the morning to find out what materials I can refer to. The question I chose happens to involve some things in microeconomics. Let me see if there are any. Appropriate papers can directly cite some processes."

After confirming, the two looked at Zhou Jingxue again... no, there should be three of them.

Zhou Yan, who hadn't turned the corner in his head, was also staring at Teacher Zhou standing there blankly at this moment. The child in the key class only felt that everything that happened this morning had a weird feeling.It directly overturned his outlook on life that he had managed to establish over the past ten years.

"No, if you like this song, you can just pay for it and download it online? I'll pay for it." Zhou Jingxue obviously didn't want to be so troublesome.

"The melody is my own creation, it's not available online." Ning Qing answered casually.

"Self-created?" Zhou Jingxue was stunned, and then subconsciously looked at Liu Xiaohan, who was as messy as Zhou Yan at this moment... Then he suddenly wanted to understand why Ning Qing searched for Lin Didi's name on the Internet.Then I asked again: "Eh...go to the music classroom? Can you borrow it?"

Liu Xiaohan directly took out a bunch of keys from the bag, shook them at Zhou Jingxue, and said, "Report to Mr. Zhou, I have the keys, and Mr. Qin specially made them for me, so that I can practice piano at any time."

"Then... alright. Come with me, I'll take you out." After hesitating for a moment, Zhou Jingxue suddenly made a decision. He happened to want to ask Luo Zhen to inquire about Ning Qing's situation.

……

Leading Liu Xiaohan out of the small building in the competition area, Zhou Jingxue couldn't help asking, "What's the relationship between Lin Didi and you?"

"My piano teacher, he has taught me for almost six years."

"Did you compose that song just now?"

"No, Ning Qing created it himself. He hummed the melody just now, and then I reproduced it."

"Ah? Ning Qing made it himself? Could it be that you didn't discuss the topic just now, but the music?"

"That's not true. At first Zhou Yan was reading a book, and Ning Qing was surfing the Internet alone. I was watching the performance skills of the world's piano masters. Then Ning Qing said that he likes to listen to music while thinking, but the computer does not have a sound card, so he hummed. A melody, and I played it to him on the harmonica."

After hearing this answer, Zhou Jingxue felt that everything was messed up...

Class [-], what kind of ghosts and ghosts are these?It's against the sky, it's even more rocket class than rocket class!

Thinking of Ning Qing's clear problem-solving ideas, thinking of the formulas he summed up casually and the hand-painted charts that look like software graphics, before that he even created a melody that sounds good so that he can concentrate on solving the problem?

Zhou Jingxue felt that he could hardly recognize the world.

So after he sent Liu Xiaohan to the music classroom, he rushed to the office of the second-year math teacher in the high school teaching building. Unfortunately, Teacher Luo was in class, but fortunately, there were only 5 minutes left before get out of class ended...

Zhou Jingxue simply took out a cigarette and began to savor the loneliness.
