IV. Contest Rules
The 2021 MCM/ICM contest period runs between 5:00 p.m. EST Thursday, February 4, 2021 and 8:00 p.m. EST on Monday, February 8, 2021.
Each team may consist of a maximum of three undergraduate (or below) students enrolled full- or part-time at the same school/institution at the time of the contest. Teams may consist of 1, 2, or 3 students and each student may only participate on one team.
Each team must have an advisor who is a staff member, a faculty member, or a student at the team members’ institution. Advisors can serve more than one team. Advisors must register teams prior to 3p.m. EST on Thursday, February 4, 2021.
Teams must obtain and use the Control Number and password assigned to them at registration to participate in MCM/ICM.
Not later than the opening of the contest window, advisors must assign team members to a particular team, and cannot add or change student assignments for the duration of the contest. Teams may, however, remove a team member, if he or she decides not to participate.
Once the contest window opens (5:00 p.m. on Thursday, February 4, 2021), team membership must be set and teams may not use any persons, other than their own team members, to discuss or obtain ideas for working on and solving their problem. Teams may use any “inanimate” resource they find on their own such as: web pages, books, articles, research reports, databases, etc. Teams may not seek help in obtaining answers, ideas, or information, or in locating appropriate resources, from any persons outside of their team to include their advisor, other teachers, other students, and/or experts or professionals in a field relevant to the problem. This restriction includes personal or telephonic contact, as well as use of electronic social media such as, but not limited to: emails, texting, chat rooms, question-answer systems, interactive blogs, Twitter, Weibo, online help or support sites, etc. Additionally, posting or sharing any part or all of the problem statement, your team’s solution process, or any partial or complete work in any form or medium during the contest is strictly prohibited. COMAP will disqualify or deem unsuccessful any team that violates this rule. The relevant issue is one of intent: each team of students is expected to develop all of its substantive analysis and solution without the help of others.
Teams must document any outside sources of information by using footnotes, endnotes, or in-line documentation, and include appropriate citations in a reference list or Bibliography of these sources.
Teams choose to work on one problem (MCM: A, B, or C or ICM: D, E, or F) and submit one solution for the problem of their choice.
The names of the students, advisor, and/or institution must not appear on any page of the solution. The solution must not contain any identifying information other than the team Control Number.
Papers must be submitted as an Adobe PDF electronic file, and typed in English, with a readable font of at least 12-point type. Papers must be within the page limit specified in the problem statement.
Upon closing of the contest window at 8:00 p.m. EST Monday, February 8, 2021, advisors must ensure each team makes no further changes to their solution paper. Advisors must then ensure all solution documents are properly prepared and sent via email to COMAP for judging no later than 9:00 p.m. EST Monday, February 8, 2021.
COMAP follows all accommodations relative to learning conditions for individual students used as part of the local school/institution program in an affected student’s daily learning. If specialized staff is required, the school bears the responsibility for providing any specialized assistan as required by law. If such accommodations are required for a student participating, the school should detail them and the extent to which the were utilized as part of the MCM/ICM activities.
COMAP reserves the right to disqualify or reduce the award level of teams found to have violated the contest rules.

During the Contest - Choosing and Solving the Problem
The contest problems become available for teams to view at precisely 5:00 p.m. EST on Thursday February 4, 2021 on the contest web site:
https://www.comap.com/undergraduate/contests/mcm
No password is needed to view the problems. Simply go to the contest web site at or after 5 p.m. EST on Thursday, February 4, 2021 and you will see a link to view the problems.
The contest problems will also become available for teams to view precisely at 4:50PM EST on Thursday February 4, 2021 on the following mirror sites:
http://www.comap-math.com/mcm/index.html
http://www.mathismore.net/mcm/index.html
http://www.mathportals.com/mcm/index.html
http://www.immchallenge.org/mcm/index.html
If you cannot access any of the sites, there may be a problem with your local Internet connection. Contact your local Internet service provider to resolve the issue.
Each registered team may choose any one of the six problem choices and should submit a solution to only one problem.
• MCM problems are Problem A, Problem B or Problem C.
• ICM problems are Problem D, Problem E or Problem F.
Teams may use any inanimate source of data, materials, computers, software, references, websites, books, etc. Teams should reference all sources used using footnotes, endnotes, or in-line documentation, and include an associated reference list citing all sources.
Teams may not seek help from any person outside of team members as delineated in the Contest Rules (specifically Rule #6).
Teams should keep in mind the following guidelines when solving the problem and developing their solution.
a. Summary Sheet: The summary is an essential part of your MCM/ICM paper and should appear as the first page of your solution report. The judges place considerable weight on the summary, and winning papers are often distinguished from other papers based on the quality of the summary. Click here to download the Microsoft Word Summary Sheet.
• To write a good summary, imagine that a reader will choose whether to read the body of the paper based on your summary: Your concise presentation in the summary should inspire a reader to learn about the details of your work.
• You should write the summary last, as it should clearly describe your approach to the problem and, most prominently, your most important conclusions. Ensure you plan time after solving your problem to write a comprehensive and articulate summary.
• Summaries that are mere restatements of the contest problem, or are a cut-and-paste boilerplate from the Introduction are generally considered to be weak.
b. Overall: The team’s solution should be articulate, concise, and organized in order to allow the reader to easily follow the solution process and conclusions. Key statements should present major ideas and results.
• A Table of Contents assists the reader in previewing the organization of your report.
• Present a clarification or restatement of the problem as appropriate.
• Present a clear exposition of all variables and hypotheses.
• State and justify reasonable assumptions that bear on the problem.
• Present an analysis of the problem, motivating or justifying the model being used.
• Summarize derivations, computations, or illustrative examples in the main body of the solution, and leave lengthy derivations and/or calculations and data in appropriate appendices.
• Include a design of the model. Discuss how the model could be tested, to include error analysis, sensitivity, and/or stability.
•Discuss any apparent strengths or weaknesses to your model or approach.
• Provide a conclusion and report results explicitly.
• Document resources and references.

During the Contest – Preparing a Solution Document
MCM/ICM solutions are judged as varying degrees of successfully completing the contest (from Successful Participant up to Outstanding). There is no passing or cut-off score, and therefore, partial solutions are acceptable and teams are encouraged to complete as much of the problem as they are able to do. MCM/ICM judges are primarily interested in the team’s thought processes, analysis of the problem, modeling approaches, and mathematical methods.
Teams must submit their entire solution in one Adobe PDF electronic file, consisting of written text, figures, charts, and supporting materials. Papers must be typed in English, with a readable font of at least 12-point type. Do not send additional “non solution” files such as data or computer programs.
Each page of the solution must contain the team control number and the page number at the top of the page. Use a page header on each page - for example: Team # 214321, Page 6 of 13.
Your solution report should start with the Summary Sheet followed by the team’s solution. Ensure your solution meets the page limit requirements as stated in the problem. A Table of Contents is encouraged and does not count toward the page limit. Reference list (or Bibliography), notes pages, and any appendices do not count in the page limit and should be included after the solution pages.
Names of the students, advisor, and/or institution must not appear on any page of the solution. The solution file must not contain any identifying information other than the team Control Number.

MCM/ICM论文被视为不同程度的成功完成竞赛（从成功参与者到特等奖）。没有通过或及格分数，因此，部分论文是可以接受的，鼓励团队尽可能多地完成问题。MCM/ICM评委主要对团队的思维过程、问题分析、建模方法和数学方法感兴趣。
团队必须在一个Adobe PDF电子文件中提交他们的整个论文，该文件由书面文本、图表和支持材料组成。论文必须用英文打字，字体至少为12号。不要发送其他“非论文”文件，如数据或计算机程序。
论文的每一页都必须包含团队控制号和页面顶部的页码。在每页上使用页眉-例如：Team # 214321, Page 6 of 13。
你的论文报告应该从摘要页开始，然后是团队的论文。确保您的论文满足问题中所述的页面限制要求。鼓励使用目录，不计入页数限制。参考列表（或参考书目）、注释页和任何附录不在页数限制内，应包含在论文页之后。
学生、指导老师和/或机构的名称不得出现在论文的任何页面上。论文不能包含除团队控制号以外的任何标识信息。
在美国东部时间2021年2月8日（星期一）晚上8:00停止对论文进行任何更改。
