What to do after mathematical modeling gets the competition problem and some ("crooked ways") tips - must see before the competition

First of all, let's make a statement , The following introduction of this article is not to say how awesome you are B, It's all my own experience —— You can learn from it ;

One 、 How to arrange after getting the competition question

First of all, let's talk about the three days after you participated in the mathematical modeling competition and got the competition questions ( Usually ) How to do ？

Most of the time to send questions is in the evening ( Such as National Games ： At six o'clock in the evening )、 Eight in the morning. ( Such as may day mathematical modeling ), Take the example of giving out questions at eight in the morning .

Schedule the process ：

The first stage （ At eight in the evening —— Before you go to bed ）： Choose a good topic , And find a lot of relevant information , Then go to bed . Don't rush to do the problem , Carefully choose the topic that suits you , There are many teams that will change the question when they are half done ...emmmm... Basically say goodbye to the Award , Remember to sleep the first night ( Keep your strength , First, don't sleep , In the next few days, I was confused , Do more harm than good ).

The second stage ( The first day —— Before you go to bed )： The first question is relatively simple , About from morning to twoorthree o'clock in the afternoon, the first question is over ( Including papers ). Then start to analyze the second question , The second question is more important , Often the following questions are done on the basis of the second question , Try to determine the problem-solving steps before going to bed , And finish processing the data . The second night is still recommended to go to bed ( But go to bed a little later ), Don't always think about Gan , Not efficient .

The third stage ( The second day —— The third day morning )： About noon the next day, the second question ( Including papers ), Do the third in the afternoon and evening 、 Four questions ( Usually four questions ). The third night, I suggest you not to sleep , Gan night , Hold on , Victory is at hand .

The fourth stage ( The third day morning —— At eight in the evening )： Change the paper 、 Typesetting 、 Optimize , If you pay attention to this aspect in the process of writing the paper before , This stage is relatively simple .

Two 、 Competition tips

There are also many sharing tips on the Internet . I also saw it in those days , It's just some serious reading questions 、 Don't make any mistakes 、 The layout should be beautiful . I feel these are not what you really want to see , I want to see some applicable tips ——“ Be opportunistic ”.

I remember when I was competing, I also found practical tricks , Want to “” Opportunistic . Hey, hey, hey , Words cannot be too plain , Afraid of being sealed , ah , Um. , Um. , It's the kind of people want to take a shortcut , Ha ha ha ha ！！！

Here are some of the modeling competitions you really want to see “ Tips ”—— Crooked ways

Especially for some contestants .

One 、 What will you do if you get the title

1、 Copy the title directly 、 Paste on Baidu , Learn about .

2、 About half a day after the question is issued , You can visit Zhihu more ,（ Such as direct search “2022 May day mathematical modeling ”）

There are many of these , And the ideas are different , That's for sure , A problem can be done with many models , So we need to screen , Draw on ideas , Extract something useful to yourself .

Two 、 Write a paper

Find a template between competitions , Apply the template directly during the competition .

  I found a better template for you here , You will be prompted how to write each part .

link ：https://pan.baidu.com/s/1UtuN0KTLULQvQU-AcSE5aw 
Extraction code ：yzh0

Be sure to use professional vocabulary when writing papers , Don't be colloquial ( for instance ： Do not appear “ We ” Such words , use “ this paper ”、“ This group ” Instead of )

When everyone is forming a team , The author tries to choose girls , Because girls' minds are more delicate , The article written is very good .

3、 ... and 、 Make an article on the model

for instance , An evaluation model , You can do it with analytic hierarchy process , It can also be used. topsis do , Because analytic hierarchy process is too subjective , It is greatly influenced by us , Let's choose topsis Law , In combination with entropy weight method to calculate the weight , Constitute entropy weight method +topsis Model . Is it more effective than a single model , And there is something written in the paper .

Analytic hierarchy process —— Grey Analytic Hierarchy Process

topsis—— Entropy weight method +topsis

Principal component analysis —— Principal component analysis +topsis etc.

Of course , We should not blindly add , Be consistent .

Four 、 How to please the marking teacher and add points

Data visualization 、 flow chart

1、 flow chart

First, let's talk about the flow chart ： Here are a lot of words and a picture for you to see , Which one do you choose , Should be able to choose pictures , Who can read that pile of words .... The marking teacher also thinks so , So we can do a lot of flow charts .

There are two types of flow charts ： One is modeling thought flow chart , One is program flow chart .

        ① Modeling thought flow chart ： Describe the idea of problem solving , Let the teacher intuitively see how he solves the problem .

        ②： Program flow chart ： How to realize the function of the established model .

2、 Data visualization

Show the data results in a graph , Most forms are made of three line tables , Make it beautiful , We must do more and be advanced , It's really important .

5、 ... and 、 Problem solving procedure

Many people worry that the program can't be written , Let's think about it , Thousands or even tens of thousands of teams , The judge teacher will read the paper again , We have to run the submitted programs one by one , How much work will be done .

So basically, which papers are particularly well written , The first prize winner , The teacher will open the program to have a look . I don't need to say more about the rest .

Of course, I hope you can take it seriously ,“ Unless you really can't write it ”.

The above is just for you to share your experience , Not to teach you how to exploit loopholes , Please understand correctly .

If there is any new idea , Welcome to discuss in private letters .
