This article is mainly about what you know about the event and how to prepare a small group of digital and analog strategies. You can make do with it. Recently, you are tired and panic. You can share with the comment section of better experience. I am Cai Feihua, I wish you and I have a brilliant life, if you like, you can follow me!
Read more excellent papers before the game is fine! ! It's useless to look at knowledge points, and you may not use them when you read them, but there are many points to learn from excellent papers. Be sure to read more excellent papers! !
Public account: your brilliant life

5. Start time for uploading competition papers: September 21, 2020 14:00, deadline: September 22, 2020 24:00 (Don’t delay, because everyone wants to submit it later, but in the end the system will always be busy, the official I just said that if you did not submit it because of your own reasons, the competition will not give you the opportunity to make up the submission!!! Be sure to pay attention)

Key Points of Paper Review
1. Data processing
Including data mining, data processing, data analysis, etc. In this era, there is often a large amount of data processing, so data processing capabilities need to be improved, and data-driven problems need to be solved. The data that needs to be used in the process of answering questions may need to be mined and processed by yourself.
2. Use of tools
Including a variety of software tools, such as programming software MATLAB, Python, writing software word, latex, etc. It is not only required to be able to use it, but also to be able to know the application of these software in mathematical modeling.
3. Demonstration ability
A good paper requires both pictures and texts. It not only requires data support, but also combines writing and scientific computing visualization to demonstrate the ability.

Key points
The topics of the competition involve all disciplines such as liberal arts, sciences, engineering, medicine, etc. One of the six major questions from A to F is selected, and each major question contains three or four small questions. The topic selection is very important. The difficulty of each question is different. Some of the questions seem simple. When you do it, you will find that the simple model cannot solve the problem perfectly. Suddenly, you can't write the paper. Change the question carefully. First, time does not allow, and less time is not the advantage; second, the changed question may not be done.
The beginning of these questions all involve topic selection skills, but there is no fixed routine for this kind of skills. After all, every year, all topics including question types will have relatively large changes. Carry out basic simulation training based on interest and expertise.
1. Common question types
竞赛题目涉及文、理、工、医等所有学科内容，A~F六道大题选一道，每道大题包含三、四个小题。选题非常重要，每题的难度不一样，有些题看似简单，做着做着会发现本来认为简单的模型无法完美解决问题，论文忽然无从下笔。换题要慎重，一是时间不允许，更少的时间不占优势；二是换的题目也不一定做得出来。 这些问题的开端都牵扯到选题的技巧，但是这种技巧又没有固定的套路，毕竟每年的所有题目包括题型都会有比较大的变化。根据兴趣与擅长，进行基本的模拟训练。 Common question types are as follows:
1. This professional competition question
Familiar, easy to learn, but hard to be new.
2. Mass competition questions
It seems simple, but it is actually very difficult.
3. Unfamiliar questions
A large number of references are often provided, but the ability to learn quickly is required.

Entry notes
1. Be sure to take a good rest before the game. The last day or two of the game may need to be overnight, which is slightly more intense.
2. Don't wait until the end of the paper to write, write as you do, the icon is clear, write the abstract at the end, and double check.
3. Choose a location with internet access 24 hours a day. The ideal state is:
Day 1: Go through all the questions in the morning and choose the topic; solve the first problem in the afternoon.
Day 2: Continue to solve the first question in the morning; continue to do the second question in the afternoon, while starting to write the paper.
Day 3: In the morning, continue to solve the second minor problem while writing a paper; in the afternoon, start to solve the third problem while writing a paper.
Day 4: In the morning, continue to solve the third small problem while writing the paper; in the afternoon, finish the paper and complete the typesetting.
Day 5: Check the papers continuously, correct minor errors, and upload the papers to the system!
If there are only three small questions for a big question, two small questions can basically be awarded, and the rest of the time depends on the team's persistence and then persistence!
4. In the final evaluation, the award is based on the same topic, not all topics are evaluated together.
5. To cite the work of others, you must have references and indicate them in the corresponding position in the text.
6. Discuss rationally when encountering disagreements, give in appropriately, and go around problems first.
7. Honesty is required. Fraudulent behaviors without modeling calculation construction results will not be scored, and the qualifications will be directly deprived of awards.
8. Model assumptions, problem analysis, model establishment, and problem solving process must be detailed and complete (for example: how to adjust parameters, etc.), and there must be no results. The workload of the team must be reflected in the paper, including the process of adjusting the algorithm parameters. Only writing the results has a great disadvantage in scoring.
9. More comparative analysis: advantages and disadvantages of models and algorithms, such as complexity, computing time, etc. Especially for problems that cannot be done, the analysis algorithm is insufficient and limited.
10. Innovation: Improve the algorithm (otherwise the possibility of winning is unlikely).

Final summary
Before the game, you must have a good rest and prepare supplies. It is recommended that you do not stay up late for the first three days and complete the task on time. You can stay up late for the last two days. Otherwise, staying up late at the beginning will affect your work efficiency. Get up at 1 am and then at 7 or 8 am to continue the game.
