Omnipotent Data

Chapter 344

On February 14th, at 20 o'clock in New York time and 8 o'clock in Kyoto time, the 22nd American Global College Students Mathematical Modeling Contest officially kicked off.

As mentioned before, this is the largest number of participants since the event was held.

A total of more than 10,000 teams from more than 30 countries and regions around the world participated.

Except that the competition takes one day longer and the language used in modeling papers must be English, other rules are no different from the national competition.

Thirty minutes before the start of the game, Cheng Nuo once again met the other two teammates arranged for him by the college.

When the two saw Cheng Nuo, they couldn't help but make the roots of their teeth itchy.

One of them asked, "Student Cheng Nuo, what did you do in the last two days? Didn't it mean that we were looking for a set of modeling problems a few days before the start of the competition, and we worked it in well?"

Cheng Nuo folded his hands together, "Sorry, sorry, I have been working on something very important these past two days, so I have to push this link away."

"However, I think it should not have any impact on our final results." Cheng Nuo added with a faint smile.

Another teammate looked at Cheng Nuo's confident look and couldn't help but smile again and again.

Where does this guy come from?

You know, this seems to be only their second meeting since the formation of the team.

In other words, the cooperation of the three of them is almost zero.

Even if he knew that Cheng Nuo was very strong, could he still be strong enough to delay two?

This is the beauty of the strong like forest!

…………

At 8 o'clock in Kyoto time, the download channel of modeling questions is opened on the official websites.

There are six modeling questions in Meisai. Choose one of them to answer. Each topic has its fixed focus.

Question A, continuous type.

Question B, discrete type.

Question C, big data.

Question D, Operations Research/Network Science.

Question E, Environmental Science.

Question F, policy.

Choose one of the questions A, B, and C, and you will participate in the MCM (Mathematics Contest in Modeling) competition by default.

If you choose D, E, F questions, you will participate in the ICM (Interdisciplinary Contest in Modeling) competition by default.

If you insist on the difference between MCM and ICM, the general MCM contest topic is more specific, the expression is concise, and the requirements are clear.

The ICM competition topics are more open, the problems are more "big", more macro, and longer in length. They are often issues of common concern on a global scale, so they generally do not rely on specific cultural backgrounds or lifestyle habits. A considerable part of the MCM questions are based on life in the United States, which is not familiar to participants from other countries, especially China.

Therefore, in most cases, Chinese contestants will choose one of D, E, and F to answer, that is, participate in the ICM competition!

Of course, the most important thing is to look at the area where the team is good at. This view cannot be taken as a conclusive view.

"The title is downloaded." Cheng Nuo heard the voice coming from his ear and turned his attention here.

The three of them all leaned slightly, staring at the computer screen, carefully scanning each question.

Question A is about road car driving.

Question B, about the placement of wheelchairs in the airport terminal.

Question C is about the US medical system under big data.

Sure enough, the three MCM questions all have a strong "American style". It can be said that the Chinese players are very unfriendly.

Especially for question C, you should know that the medical system in the United States is very different from that in China.

In this case, if the Chinese team chooses this question, it will take at least three or four hours to look up relevant information on the Internet to understand the relevant knowledge of the US medical system.

In a modeling contest where time is so precious, this is indeed a luxury. Unless some teams are very good at modeling big data, no one will choose this topic stupidly.

Cheng Nuo can almost foresee that among the six questions, this question is probably the least the team will choose.

After all, among the players from more than 30 countries participating in the competition, only the U.S. players are knowledgeable about this aspect, so there is no need to waste unnecessary time.

Cheng Nuo then looked down at the last three questions.

Question D, measuring the evolution and influence of the association’s information network.

Question E, the construction of sustainable cities.

Question F, Modeling refugee immigration policy.

"Which way do we choose?" Cheng Nuo's teammate of the Academy of Accounting asked.

The teammate from the Foreign Languages ​​Institute kept his eyes on Cheng Nuo without speaking. The meaning was self-evident.

Although he is skeptical of Cheng Nuo's strength, after all, Cheng Nuo is nominally the captain of the team. At this time, he still has to listen to his opinions.

Cheng Nuo pondered for a few seconds before speaking slowly, "My personal opinion, choose A. Of course, if you don't want to, we can change one."

He is an indifferent attitude.

Anyway, he can come to all six questions, and he has no pressure to reach the level of O award (special award) guaranteed before. The difference is just a matter of time-consuming.

For example, if you choose question C, even though Cheng Nuo's ability is great, it will take some time to check relevant information. This is somewhat inconsistent with Cheng Nuo's concept of saving time.

Therefore, his personal opinion is to choose a road vehicle driving problem that is no stranger to the three.

The road rules in the U.S. and China are the same, driving on the right.

After thinking for a while, the two teammates nodded together, "Okay, just pick A."

In less than five minutes, their group's topic selection was finalized.

Next... officially started!

Cheng Nuo is responsible for modeling, the teammate from the Academy of Planning is responsible for programming, and the teammate from the Foreign Academy is responsible for writing the paper.

The three perform their duties.

Cheng Nuo sat in front of the computer and looked at the modeling topic carefully from beginning to end:

[In some countries where cars are required to drive on the right, multi-lane highways often use such a rule: drivers are required to drive in the rightmost lane when driving, except in the case of overtaking, they should move to the adjacent lane on the left , Overtaking, and then returning to the original driving lane (that is, the rightmost lane). Please build and analyze a mathematical model to analyze the performance of this rule in light and heavy traffic (that is, when there are fewer vehicles and traffic jams)? You can study the balance between traffic flow and safety~www.readwn.com~The effect of maximum or minimum speed limit (ie, too low or too high speed limit)...]

Unlike the other five topics, which are new urban construction and refugee immigration, this is a very confident topic. Cheng Nuo estimates that there are many groups that choose the A topic.

However, the O prize is not evenly distributed to each topic, but the best one gets it. Therefore, it is possible that all 20 O prizes appear in one topic.

This is why the two teammates can happily agree to choose A question.

After reading the topic carefully, Cheng Nuo didn't rush to start modeling.

More haste less speed.

Before modeling, preparations must be done.

He needs to find some papers and books to learn some knowledge about road traffic.

It doesn't take long, about half an hour.
