Chapter 21 Difficulty in Choice

For mathematical modeling, interest is the best teacher, and that is Ning Qing. Of course, he gave up the first time when he saw boring questions. But soon Ning Qing discovered that in this mathematical modeling competition, there seemed to be few questions that make people interested in answering.

For example, the second-ranked airport taxi problem requires establishing a selection decision model with the objective function of the maximum profit under different decisions from the perspective of the manager; the third-ranked enterprise raw material ordering and transportation planning model based on optimization algorithms...

This competition gave a total of eight questions, and seven of them were closely related to corporate operations and management. I didn’t see any questions like the purely technical field analysis given to him by Luo Zhen that day.

Well, it seems that the economic situation in the world has been really not good recently. Even the questions presented in the mathematical modeling competition are of this kind of economic orientation...

As for the last question, Ning Qing was confused.

The description of the question is very simple: scientists believe that the operation of any event in this world follows certain laws, ranging from the operation of celestial bodies to the distribution of particles. This also means that all problems may be solved by mathematical models. Which problem do you think in this world that has not yet been paid attention to by scientists is worth solving with mathematical models? This question allows you to freely exert your ability, ask questions independently, and solve them through mathematical modeling. Maybe you are the next Robert Cardi.

Obviously this is a question with extremely high degree of freedom, but it also means that the difficulty of this question is directly overwhelmed. Even the two words (check carefully) are directly indicated at the back of the question stem.

This is why students like Ning Qing, who are not a professional class, look at the question specifically. In fact, since the World Mathematics Modeling Competition began eight years ago, this question is a guaranteed question that appears every year in college students. It is also a question that coaches have told their students that they must not choose countless times.

Because in the coaches' opinion, even if the best college students dare to choose this question, their final scores will not be too high, because knowledge accumulation is not enough. This is true. In the past seven years, no one has won the award on this question, even though he knows that this question will appear in the question bank.

Ning Qing actually felt that such open questions should not appear in this level of competition at all, because this is not a question that can be completed in three days at all.

However, this did not prevent him from searching for Robert Cardi online, and then was shocked.

This is a real genius on Sky Blue Star. Although he died young only at the age of 32, he left too many things on Sky Blue Star. For example, this big man is the pioneer of quantum physics in this world. He completed the research results of Schrödinger, Boer and Pauli on Earth in a limited ten years, and was so awesome that he had no friends.

In the year of his death, quantum mechanical measurement provisions were proposed to make the entire set of theories relatively complete.

What made Ning Qing even more speechless was that this guy's way of death was so legendary.

According to the online statement, the old man was blown to death by what he created while studying nuclear fission. Simply put, Mr. Robert Cardi built an atomic bomb, but failed to control it well and exploded. And the boss was at the center of the reaction at that time, and the whole person should have been instantly vaporized into molecules...

...

Ning Qing didn't know how strong the control desire of his beloved Teacher Zhou was. Or how strong the teachers in this world had. The computers prepared for this competition were all installed with control software. In other words, Zhou Jingxue could monitor all the operations of students on the computer in the background.

So after Ning Qing expressed his feelings in front of Zhou Jingxue last night, he originally intended that the paper submitted after the competition would be taken seriously, but Teacher Zhou had already paid enough attention to him at this moment. For example, he had already begun to care about his topics early on.

So Zhou Jingxue knew that while others were frantically refreshing the question database, Ning Qing browsed international news online at Yonghan's most authoritative online news platform - Yilan, and spent more than half an hour to view various related expert comments and articles.

Zhou Jingxue doesn’t know how to evaluate this kind of behavior. This is probably super confident?

Finally, the question bank link was updated thirty-two minutes later, Ning Qing logged out of Yilan.com and logged into the Haizhou Municipal Education Bureau system. Then he clicked in and read each question.

The background cannot see the specific process, but it records the time Ning Qing stayed on the exclusive page of each question, and it stayed for seven or eight minutes, which was more than an hour passed. At this time, most other groups should have selected the questions and started to search for various related information on the Internet, but Ning Qing still had no operation, which probably means that this guy has not selected the questions yet.

Oh……

Zhou Jingxue suddenly felt that his IQ might have decreased. Yesterday, he had so much anticipation for this guy from Class 9. This was very similar to those young boys who couldn't understand the questions at all. But the head coach was still in a good mood.

Because he bet on the questions this year, he bet on the questions in the last half month of intensive competition thinking training class, he bet on at least three similar questions. If the Rocket class students who participated in the mathematical modeling interest class really understand the questions he was talking about, they only need to undergo a simple change and they should get a good evaluation.

And from the choices of these children, we can see that they all chose one of these three questions. This shows that they can all see the relationship, which is very comforting!

...

"Ning Qing, have you chosen the question?" Liu Xiaohan, who had been secretly observing Ning Qing, couldn't help but ask.

"Not yet, I'm looking for music software, but there is not even a music player on this computer. Haha, they even blocked the sound card." Ning Qing answered casually.

He acted very easily, but in fact, Ning Qing's mind was running rapidly. The simple ones were arranged too simple, and the difficult ones were too difficult. If he had enough time, he really wanted to challenge the last final question.

But it was too late to see this question just now. If you still have this question when you are participating in the national competition or representing the Yonghan Republic in the World Championship, you can consider it.

Then choose...

"What music do you want to listen to? I'll play the harmonica for you?" Liu Xiaohan suddenly gave a suggestion.

"You can still play the harmonica?" Ning Qing was a little surprised.

"Actually, I also know flute and trombone, but I only bring a harmonica. My music enlightenment teacher is Lindidi, and he knows a lot of musical instruments." Liu Xiaohan also explained, and then took out an exquisite harmonica from his schoolbag.

Zhou Yan, who had been studying silently, suddenly raised his head: "Wait, what did you say? Is your teacher Lindidi? Is Didi's unparalleled Lindidi?"

Ning Qing subconsciously opened the browser again, entered "LINDIDI" using the pinyin input method, and the name Lindidi indeed appeared in the first place.

Well, is the currently recognized number one pianist in the Yonghan Republic?

Seeing this result, Ning Qing immediately decided to choose the simplest question, shopping mall discount issue... The extra time is just right for me to discuss music with Xiaohan. In this strange world, it must be a very romantic thing to appreciate the familiar melody that only exists on the earth.
