An Invitation to Secondary School Students in the Greater China Region for IMMC2020


      We warmly invite secondary school students from Mainland China, Taiwan, Hong Kong and Macau to participate in the 6th Annual International Mathematical Modeling Challenge- IM2C 2020. The registration for the Greater China Regional contest has started. Let’s join our hands together and pursue a journey of creation and discovery in the coming season.


      International Mathematical Modeling Challenge (IMMC or styled as IM2C) is an innovative contest in mathematical modeling for secondary school students all over the world. The aim of IM2C is to promote mathematical modeling education and enhance students’ core competencies in mathematics and innovation, encouraging participants to explore the application of mathematical modeling in real life situations to solve problems of importance. IM2C in this Region is an inclusive and sharing platform both for secondary school students to practice mathematical modeling, and for schools to demonstrate and exchange their educational accomplishments in mathematics and STEM. 

      IM2C in Greater China Region is an interdisciplinary practice integrating mathematics with science, technology and engineering which reflects the essence of STEM education. The co-founder of IM2C NeoUnion ESC Organization works with the Institute of Electrical and Electronics Engineers (IEEE China) and Hong Kong Society for Industrial and Applied Mathematics to co-organize the IM2C 2020 in Greater China. The Problem Setting Committee and the Judging Panel consist of experts and professors from IM2C Committee (Zhonghua), IEEE and HKSIAM whose disciplinary fields cover mathematics, science, technology, and engineering. Prof Raymond Chan, Dean of School of Science of City University of Hong Kong, Fellow and Council Member of SIAM serves as Chairman of IM2C 2020 Greater China; Prof Yang WANG, a member of IM2C International Expert Panel, Dean and Chair Professor of School of Science at The Hong Kong University of Science and Technology acts as Chairman of the Problem Setting Committee and Grand Jury of the Final Presentation Competition of IM2C 2020 Greater China.

      IM2C 2020 and its Rules

      To cater for the diversity in school calendar across the Region, two seasonal contests, namely Autumn and Winter Contest, will be open for IM2C 2020. Teams may choose one of the seasonal contests according to their schedule to compete for the yearly awards in the region of Greater China and qualification to proceed to the international round. 

      IM2C encourages interdisciplinary innovation and teamwork for students and teachers.  IM2C requires each team to be composed of 2-4 students from the same secondary school, and at least one teacher from the same school to serve as team advisor. Participating teams from all over the world will be selected by a national/regional selection process before they enter into the international round of IM2C. For both the national/regional and the international round of competition, winning teams will be recognized as different levels of awards.

      Participating teams from Greater China region can choose: 1) to work on a problem created by the Problem Setting Committee of IM2C Greater China starting from 8:00 pm on November 21st (Thu) 2019 (GMT/UTC+8 hours), Autumn Contest, or January 16th (Thu) 2020 (GMT/UTC+8 hours), Winter Contest. During the following consecutive period of 96 hours, teams must complete and submit a solution paper of mathematical modeling; 2) alternatively, register for a self-challenging problem, i.e., the team can choose freely a problem set by the team members themselves. Note that such problem must be a real-world problem discovered and identified by the team. To work on the freely-chosen problem, teams 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 8:00 pm November 25th (Mon) 2019 (GMT/UTC+8 hours), or January 20th (Mon) 2020 (GMT/UTC+8 hours), 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 2020.

      IM2C 2020 International Round in the Greater China Region will start at 8:00 pm March 10th (Tue) 2020 (GMT/UTC+8 hours), and end at 8:00 pm March 15th (Sun) 2020 (GMT/UTC+8 hours). Within a consecutive period of 120 hours, teams entering the IM2C international round will work on the problem set by the International Expert Panel, complete and submit their solution paper on or before the end of the contest period. Teams from over 30 countries and regions will be selected by their country/region to enter IM2C 2020 International Round.

      Final Presentation Competition

      The finalist teams of IM2C 2020, both for the Greater China Regional and the International rounds, will receive invitation from the IM2C Committee to come to Hong Kong/ Greater Bay city during April 24 - 25, 2019, and attend the Final Presentation Competition, presenting and defending their works in front of the Grand Jury.

      IM2C Committee Greater China will also select the best two papers from each of the Mainland, Taiwan, Hong Kong and Macau finalists in the International Round (totally 8 papers) for recommendation to the International Expert Panel. (Each participating country or region will select the best two papers for the International Panel’s Judgement.) 

      Recognition and Award Ceremony

      The participating teams from Greater China Region will have the equal chances to be recognized with different awards at both regional and international levels. The papers will be judged as per categories of Greater-China-Committee-set problem, freely-chosen problem, and International-Expert-Panel-set problem, respectively. Each participating team, no matter whether or not they are selected into the International Round, will have the chances to compete for the awards of the Greater China Region.

      An IM2C 2020 Greater China Summit cum Summer Workshop and Award Ceremony will be held in the summer of 2020. This will be a prestigious academic conference of the Region for secondary school students and teachers exclusively. Teams winning the Outstanding Award of the Regional and/or International contests will be invited to deliver plenary speeches at the Summit. Members of IM2C Committee and the Problems Setting Committee along with renowned experts in relevant fields will also be present, so as to interact and exchange with the secondary school students and teachers. Winning teams of the International Outstanding Award  or Global Top 5 teams will be invited to attend the themetic activities and award ceremony on The 14th International Conference on Mathematics Educaiton to be held in Shanghai ( ).


      IM2C 2020 Greater China will adopt the bilingual policy. The solution paper and presentation for both IM2C Greater China regional and the international contests can be written and conducted in either Chinese or English. But papers which are submitted to the International Expert Panel for international final judgement must be written in English or translated into English before submission.

      Registration and Submission

      The registration fee for IM2C 2020 Greater China is US$ 55 per team, for either Greater China Committee-set problem or freely-chosen problem. The International Round is free of charge.
