A student team from the University of Macau (UM) received second prize at the Contemporary Undergraduate Mathematical Contest in Modeling of China (CUMCM). This is the fourth consecutive year that UM has received prizes at this contest. This year’s contest attracted 36375 teams from around the country, including 7 teams from Macao.
The UM team were comprised of three students, namely Poon Tsz Yeung, Luo Ruixiao and Yao Yinlong, the team was led by Dr. Liu Zhi from the Department of Mathematics.
Dr. Liu Zhi also received the excellent advisor award. The award is issued every ten years to the selected advisors around the nation.
Organized by the China Society for Industrial and Applied Mathematics, the CUMCM is a national contest in the field of mathematical modelling. It is also the largest mathematical modelling contest in the world. This is the 15th CUMCM contest, attracted more than 100,000 students in 36375 teams from 34 provinces, cities, and autonomous regions in China, as well as from Australia. Only about 5 percent of the teams received first or second prizes.
This year's contest consisted of two problems: Problem A and Problem B. The awarded team has chosen the Problem B, which is very real-world relevance. The problem is about the photo-taking task pricing. The students were asked to find out the reasons of low rate of successes. The team has employed the logistics regression method to explain the source of low rate of successes and established the task-allocation and pricing model via density based DBSCAN clustering method. Finally, they used the proposed model to conduct forecasting and evaluation.
Department of Mathematics has paid attention to improving the students’ skill of mathematical modelling. To provide consultancy and support to the students around the university, in early 2017, a committee of mathematical modeling consisting of three professors (Prof. Ding Deng, Prof. David Lei and Dr. Liu Zhi) has been established, and a sub-organization of UM Student Union entitled Mathematical and Interdisciplinary Modeling Association is formed. In recent years, in addition to the CUMCM, UM students have also won prizes at the variate modeling contests of United States and China.
