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 IM²C co-founder NeoUnion ESC Organization works with the Institute of Electrical and Electronics Engineers (IEEE) and Hong Kong Society of Industrial and Applied Mathematics (HKSIAM) to co-organize the IM2C 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 Yang WANG, Vice-President for Institutional Advancement and Chair Professor of Mathematics of The Hong Kong University of Science and Technology and a member of HKSIAM Scientific Committee serves as Chairman of the Problem Setting Committee and Grand Jury of the Final Presentation Competition of IM²C 2023 Greater China.

The Hong Kong University of Science and Technology (HKUST) has inspired the participants with its leading research achievements, high quality teaching and top-notch teaching and research talents. In his speech, Professor Yung Hou WONG, Dean of School of Science, said that this was the second time that the HKUST School of Science hosted the competition, and he warmly welcomed everyone to the HKUST campus for face-to-face interaction.

Professor Yang WANG, Vice-President (Institutional Advancement) of HKUST and Chairman of Expert Panel and Grand Jury of IMMC Greater China, congratulated all the finalist teams for their achievements in the 2023 competition. In his speech, he pointed out that mathematics is not only a fundamental subject that encompasses symbols, logic and abstract thinking, but is also used in all areas of technology, engineering and social life today, as shown by the rich variety of IMMC constest problems. He encouraged students to set higher goals and pursue advanced studies.

Prof Yang WANG, Vice-President(Institutional Advancement) of HKUST as Guest of Honour delivered greeting speech.

Besides the competition, a variety of campus tours and workshops were arranged for par research facilities to showcase the latest achievements of HKUST in research and teaching.rticipating students and teachers to learn more about the University. Student volunteers from HKUST took students and teachers visiting the Physics Laboratory, Materials Characterisation and Preparation Centre, Robotics Laboratory and others.

Finalist teams from Mainland, Taiwan, Macau, and Hong Kong attended the opening ceremony of IMMC 2023 Final Presentation Competition on April 28, 2023 ,at the Jockey Club Institute for Advanced Study (IAS) of HKUST

After three years of online competition, the IMMC 2023 Final Presentation Competition was held physically on campus, bringing together students, experts and judges. Out of approximately 900 teams, 52 from the region presented their solution papers on regional-committee-set problems, Self-chosen problem, or International-committee-set problems in front of the Grand Jury on the Final Presentation Competition. Twenty-two teams, including Diocesan Girls’ School, Pui Ching Middle School (Macau), Beijing Academy, Shenzhen College of International Education, Taipei Wesley Girls High School, were awarded the IMMC 2023 Outstanding Award, including 11 teams winning the Outstanding Award in the Regional Contest and 11 teams winning the Outstanding Award in the International competition. Hou Kong, Shanghai World Foreign Language Academy, Shanghai Experimental School, and Pui Kiu College were awarded the Outstanding Award in the Middle School category.

HKUGA College team reported their solutions on 29 April 2023 at Hong Kong University of Science and Technology (Clearwater Bay)

The IMMC 2023 in Greater China is an independent competition as well as functioning as mechanism for the selection of teams for IMMC International Round. IMMC 2023 contest problems include:
