The last week! Summary of pre competition preparation for digital model American Games

​ Bloggers are also preparing for the digital model competition recently , I know the efficiency of winter vacation at home , But there is still one week left xdm！ Although I am not very good at mathematical modeling , Before, I had only one experience of saving one , But I still want to sort out and summarize some things about preparing for the US games for you .

Important time

​ Because the competition time is very short , Every minute counts , So it is very necessary to know the time point in advance .

2022 Date and time of the annual competition ：

• Registration deadline ： Beijing time. 2022 year 2 month 18 In the early morning of Friday, Sunday 4:00 Before .
• Starting time ： Beijing time. 2022 year 2 month 18 Friday morning 6:00.
• End... End ： Beijing time. 2022 year 2 month 22 Tuesday morning 9:00.
• Submission deadline ： Beijing time. 2022 year 2 month 22 Tuesday morning 10:00.
• Results release time ： The results of the competition will be announced in late May .

About team building

​ First , There are at most three people in a team . Be careful ！ These three people must all belong to the same school , In other words, it is not allowed to form teams across schools . And all three members must be undergraduates （ Or middle school students ）, Graduate students are not allowed to attend . There should also be a tutor in the team , The instructor must complete the registration process for each team .

Some important rules

• Before the competition , Teams must fill in the form of a team member , And you cannot add or change team members during the competition . however , If the team member decides not to participate in the competition , The team can delete it .
• The paper must be written in Adobe PDF Submit in electronic form , And write in English , The font size must be at least 12pt, The paper must be in 25 Within the page .
• Student 、 Mentors and / Or the name of the organization must not appear on any page of the solution . The solution must not contain any identification information other than the team control number .

writing

​ First , It is strongly recommended that you prepare a paper template before the competition , And set it according to the required format .

The page ： Summary is MCM/ICM An important part of the thesis , Should appear as the first page of the solution report . Abstract accounts for a high proportion in the review , Award winning papers are often distinguished from other papers according to the quality of abstracts . Click here to download Microsoft Word The page , Or click here download LaTeX The page .

• To write a good summary , Imagine the jury choosing whether to read the text of the paper based on your abstract ： Your concise statement in the abstract should inspire the judges to understand the details of your work .
• You should write the final summary page , Because it should clearly describe your solution to the problem , Especially your most important conclusion . Make sure you take the time to write a comprehensive and clear summary after solving the problem .
• Just a restatement of the competition , Or cutting a part of the previous statement as an abstract is usually considered not to be feasible .

​ The team's solution should be clear 、 concise 、 Organized , So that readers can easily understand the process and conclusion of the solution . Key statements should present the main points and results .

• The table of contents helps readers preview the organizational structure of the report .
• Refine or restate the problem according to the situation .
• Articulate all variables and assumptions .
• State and prove reasonable assumptions related to the problem .
• Give problem analysis , Explore or justify the model used .
• The main part of the solution should include the summary and derivation of the theory 、 Calculation or illustrative example , And leave a lengthy derivation and... In the appropriate appendix / Or calculation and data .
• Including the construction of the model . Discuss how to test the model , Including error analysis 、 Sensitivity and / Or stability analysis .
• Discuss any obvious advantages or disadvantages of your model or approach .
• Provide conclusions and clearly report results .
• Document resources and references .

Topic selection

​ It is very necessary to pre select the topic before the competition ！ You need to look at the questions of previous years to understand the six types of questions and their characteristics , Choose the appropriate question type in advance , So as not to spend too much time on topic selection during the race .

Massey is currently divided into two types ,MCM and ICM. The two types of competitions are conducted according to unified standards , After the competition topic comes out , The parameter team selects topics through the official website of Massey , Divided into 6 Types of questions .

MCM:

The participants' mathematical model literacy and modeling ability are required to be high ,

commonly A It is called continuous problem 、B It is called discrete problem .C topic , It is related to big data and data mining .

ICM:

Generally, the problems involved are macro and complex . For the contestants, grasp the main line of the problem 、 The ability to balance macro and micro wholeness and details is highly required .

ICM Yes 3 Problem ,D Questions are generally related to network science or optimization ,

E The question is related to environmental science ,

F Problems and policies 、 Social science related , This paper mainly discusses modeling in social sciences .

Software preparation

• MATLAB： Matrix lab , The simulation effect is very good , Received a lot of tool kits , Experiments are often done
• SPSS： Data analysis and evaluation models are commonly used
• lingo： Commonly used for operational research optimization

Drawing tools

The mainstream of Matlab、R、Origin、Python etc. , Need a certain programming foundation . Those with poor programming foundation can also choose the following ：

• Visio： Microsoft products , Vectorgraph 、 High definition 、 No watermark 、 free
• Excel： Broken line diagram 、 The pie chart 、 Scatter plot 、 Radar charts can be drawn
• Tableau： The characteristic map is like the distribution map （ With China 、 The kind with the world map as the background ）, Free trial 14 God .
• PPT： It is said that those who use this are cruel people .
• A hundred million diagrams ： Many templates , Online drawing , Very convenient ！
