7th International Mathematical Modeling Challenge
IM2C 2021 Instructions and Rules
To participate in the International Mathematical Modeling Challenge (IMMC or IM2C), all team members must be coming from the same school. There are several steps that a team advisor must go through before, during and after the contest. Please read this instructions and rules document carefully and ensure to complete all the procedures involved. It is the teacher advisor's responsibility to make sure that the team will follow all steps required for participation in IM2C.
A team may consist of 2-4 secondary school students, enrolled in the same school. There must be at least 1 faculty teacher from that school as an advisor. There is no limit of the number of participating teams from one school.
Participating teams in IM2C from all over the world will be selected by a national/regional selection process before they enter the IM2C International Round. Teams from Mainland, Taiwan, Hong Kong and Macau of China will firstly be selected from the IM2C Greater China Round.
Teams who work on the Committee-Set-Problem must complete and submit the solution paper within 96 consecutive hours (4 days) at the assigned period of time. Teams working on the Self-Chosen Problem can decide on their own about the starting time and schedule; however, they must complete and submit their solution paper of modeling on or before the deadline of the seasonal contest in Greater China. Solution papers of the two categories will be judged separately. Teams whose papers are judged as among the top 20% of the two categories of papers respectively will automatically proceed to the International Round of IM2C 2021.
Registration process, downloading problem/control sheet and uploading papers/materials for participation in Greater China should be performed on the online contest system: www.immchallenge.org.hk. Teams who participate first time have to sign up to the system to create their account with username (valid email address) and password. By logging in with the email address and password, the team can register for the ongoing contest under the “Event” column. Successful registration will grant the team a Control Number for the chosen contest. (Note: Signatures of parents/guardians is not required on the control sheet; but their names must be filled. The teacher advisor is required to sign off the control sheet with authorization by and on behalf of parents/guardians.)
The registration fee for IM2C 2021 Greater China is US$ 100 per team, for either Greater China Committee-set problem or freely-chosen problem. If the team needs an individual review report of their solution paper, they should pay extra US$50 when registering. The fees are used for cost sharing and non-profit purpose only. The International Round and Final Presentation are free of charge.
Teams who choose Committee-Set-Problem can start at 8:00 p.m. on Thursday 19 November 2020 (GMT/UTC +8 time zone) for the Greater China autumn contest; and/or 8:00 p.m. on Sunday 31 January 2021 (GMT/UTC +8 time zone) for the Greater China winter contest. Teams must complete and submit a solution paper on the problem within the consecutive 96 hours. For the teams who choose Self-Chosen Problem, they can decide the starting time and the work schedule by themselves. All teams (of both Committee-Set-Problem and Self-Chosen Problem) must submit their papers on or before the deadline - 8:00 p.m. on Monday 23 November 2020 (GMT/UTC +8 time zone) of Greater China autumn contest; 8:00 p.m. on Thursday 4 February 2021 (GMT/UTC +8 time zone) of Greater China winter contest.

The advisor must upload the signed control sheet to the contest system in PDF or jpeg/png format along with the paper submission.
School should address students’ learning and living needs due to the participation in the IM2C contest. All accommodations relative to learning conditions for individual students would follow the accommodations used as part of the local school program in an affected student's daily learning. If specialized staff is required by local regulation and law, the school bears the responsibility for providing any specialized assistance as required by law or regulation.
Preparing a Team
Please read the IM2C Instructions and Rules document carefully before joining the competition. For more information and sample problems of the contest, please visit immchallenge.org.cn, immchallenge.org.hk or immchallenge.org. Providing the necessary training and coaching for students before the contest is allowed and beneficial.
Ensure that students have access to computers that enable them to word process, use a spreadsheet and relevant software, and dynamically compute and model both graphs and geometric relationships. In addition, students should have access to graphing calculators.
The advisor is required to obtain the consent from parents/guardians of all students of the participating team and sign on the control sheet on behalf of them. By signing the form, parents/guardians agree their child's work are available (with confidentiality assurance) for use as model paper and training materials for IM2C professional development activities. Additionally, should their team be designated as an Outstanding or other award winner, the student's solution paper (or solution abstract) will be published. Signed form should be submitted in PDF or jpeg/png format along with the solution paper for review by the Expert Panel judges.
Preparing a Solution Paper
When teams are ready for the contest, the team advisors may login to the IM2C Greater China website after the starting time to download the problem and distribute it to the team. The problem of IM2C 2021 (Great China Round) for Committee-Set Problem will be released at 8:00 p.m. on 19 November 2020 for Greater China autumn contest and 8:00 p.m. on 31 January 2021 for Greater China winter contest on the IM2C Greater China contest website. For teams who choose Self-Chosen Problem, they can decide the start date and the work schedule by themselves, but need to submit their solution paper before the deadline of the contest. After the IM2C International Round begins, the international problem can be downloaded from the IM2C Greater China website.
Teams may use any inanimate source of data, materials, computers, software, references, websites, books, etc. However, all sources must be credited properly in the paper.
Whether teams choose Committee-Set Problem or Self-Chosen Problem, they may not use any person (other than team members) to discuss or obtain ideas for solving their problem nor may they seek help in obtaining an answer from the teams' advisor or anyone else. Any team that discusses the problem with anyone in a position to supply them with information reflecting experience or professional expertise will be disqualified. The relevant issue is one of intent: each team of students is expected to develop all of its substantive analysis without the help of others.
Partial solutions are acceptable. There is no passing or failing cut-off score, nor will numerical scores be assigned. The judges are primarily interested in a teams’ approach and methods and also how the team defines a problem and solves the problem (especially for Self-Chosen Problem).
For the IM2C (Greater China Round and International Round), teams can submit the paper and deliver finalist presentation in English or Chinese. However, papers submitted to the International Expert Panel via the International Round must be in English or translated into English. Papers must be typed and in English. That means, if a paper in Chinese is selected by the Greater China Expert Panel and will represent the region to join the international judging, the paper must have been translated into English. Note: Teams from Mainland, Taiwan, Hong Kong and Macau of China can submit papers in Chinese at the International Round on or before the deadline of the IMMC 2021 of International Round, but papers selected for review by the International Expert Panel must be submitted in English translation. The teacher advisor must ensure that any translation is of the actual paper submitted, i.e. no changes have been made during the time it takes to translate the paper. The translation must be a word for word translation and no improvements may be made.
The paper you submit should include a one-page summary sheet which should be the first page of your solution paper. Your full solution should be no more than 21 pages (with summary page, excluding appendices and references). The summary is a very important part of your paper. The judges place considerable weight on the summary; the winning papers are always distinguished from other papers based on the quality of the summary. A summary is a first step for judges to decide whether they will continue the reading of the paper. Thus, a summary should clearly describe your approach to address the problem and, most prominently and what your most important conclusions were. Your concise presentation of the summary should inspire a reader to learn the details of your work. 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.
The solution must consist entirely of written text and possibly figures, charts, or other written material only. Supporting materials such as computer disks will not be accepted except that materials such as computer program are required specifically and clearly.
Each page of the solution paper must contain the team’s Control Number and the page number at the top of the page; we suggest using a page header on each page for example: Team # IMMC20010101 page 8 of 18.
The names of the students, advisor, or school/institution must not appear on any page of the solution. The solution must not contain any identifying information except the team control number.
Any rule not followed is ground for disqualification.
Teams should keep in mind the following guidelines while preparing their solution papers:
