IMMC2019 distinguished guests, Organizing Committee and Grand Jury members

Mr. Leo Liu emphasized that mathematical modeling is not only about mathematics knowledge, but also concerns interdisciplinary integration, computational thinking and creativity. Mr Leo Liu said, "We are in the Era of Digital and Artificial Intelligence where Cloud Computing, Big Data and Artificial Intelligence are developing rapidly. Because of the fast development of the intelligent technology, many types of job will disappear in the coming future. Some jobs with repeatable duties may be replaced by AI. But, the problem-solving ability and creativity is specific and precious competency that human beings possess. Therefore, IMMC is a valuable platform which provides a place not only to test your basic knowledge, but also for you to solve the real problems with the knowledge and skills you have. This will practice your computational thinking and creativity."

He remarked "Alibaba pays much attention on nurturing mathematical talents. Alibaba Cloud as the cloud computing platform, we work for promoting the innovative change in society through using technology. We combine data analytics, AI, machine learning and Internet of Things (IoT) to help our customers to realize digitalization."

Mr Liu added that Alibaba Cloud promotes the cooperation with schools for assisting the youth innovation and fostering the technological talents to satisfy the needs nowadays and for the future as well. He said, "Promoting the digitital transformation and Smart City is a continuous process of efforts. We hope that the students participating in IMMC will join us in the future."

Prof. Martin D.F. Wong congratulated and praised the students for their passion and creativity shown in their high quality papers. Prof. Wong quoted from the 18th century great mathematician Carl Friedrich Gauss, “Mathematics is the Queen of Science” and pointed, "Science is the foundation of Engineering. Therefore, mathematical modelling is immensely critical for solving scientific and engineering problems. In fact, applications of mathematical modelling go beyond science and engineering. Today, mathematical modelling is also widely used in economics, business, linguistics, psychology, sociology, political science etc. etc."
  
As a fellow of Institute of Electrical and Electronics Engineers(IEEE) and a fellow of Association for Computing Machinery(ACM), Prof. Wong used the system of linear equation as an example to illustrate the role of mathematical modeling that "modelling by a system of equations are responsible for keeping commercial airplanes on the sky, satellites in orbit, designing computer chips, keeping your computer runs (operating system), auto-driving cars, robotics, AI, GPS, financial forecasting, study of social behaviour, etc."

Prof. Wong pointed out that mathematical modelling is a useful tool/skill that will open doors for students in many fields. He encouraged young secondary school students to pursue their life as our next generation of scientists, engineers, and entrepreneurs as a generation of the future of China.

The Representative of Huawei Hong Kong Research Center - Dr. Michael Zhang told the audience an discovery when he worked in Huawei: "Math is important and mathematical modeling is more important because it provides a bridge that connects various math tools and practical problems. "The tools such as convex optimization, stochastic process, statistical learning, and control theory. Using such tools, they on one hand solve problems in existing products and on the other hand exploit what will happen in the future so as to point directions to the future development of the next‐generation products."

Dr. Zhang shared his personal growth experience driven by curiosity and pointed out, "a lifelong learning attitude is critical to maintain your competence in this fast‐changing world and if you have a dream, stick to it and try your best to work on it." Dr. Zhang emphasized that Huawei has various platforms to help innovators realize their dreams. He concluded, "we believe only through collaboration can we together solve  world‐level problems, break more technology limits, and make more contributions to  the entire human beings.".

Mr. Steven Deng introduced IEEE, the largest professional organizaton in the world, with its development and influence in the advancement of technology for humanity.

The programming team from the Department of Computer Science and Engineering won a bronze medal at the 43rd Annual World Finals of the International Collegiate Programming Contest (ICPC) held in Porto, Portugal. The team consists of three undergraduate students: Yik Wai-Pan (Computer Science major), Ho Ngan-Hang (Computer Science minor, Mathematics major), and Poon Lik-Hang (Computer Science minor, Quantitative Finance major). This is the third time CUHK has won medals at the ICPC. 

Established in 1970, the ICPC (formerly named as ACM-ICPC) is the oldest, largest and most prestigious programming contest in the world. This contest is a multi-tier competition from local, national, and regional contests leading to the world finals. The competition attracts the best and brightest students from around the world every year. It fosters creativity, teamwork, and innovation in building new software programmes, and enables students to test their ability to perform under pressure. This year over 52,000 contestants from over 3,200 universities from 110 countries took part in the competition, and only 135 teams advanced to compete in the world finals. The CUHK team ranked 12th and won a bronze medal in the world finals, defeating traditional prestigious teams from Stanford University, Princeton University, Harvard University, Carnegie Mellon University, University of Cambridge, Tsinghua University, Shanghai Jiaotong University and Peking University. 

Formed in the early 90’s, CUHK’s programming team has entered the ICPC world final 17 times, the first time being 1994. In 2000 they won a bronze and in 2012 a silver medal. Former, graduated team members are still contributing by passing on their experience, knowledge and techniques to serving members. Professor Chan Siu On, the team’s current coach and Assistant Professor of the Department of Computer Science and Engineering of CUHK, was in fact a key programming team member during his undergraduate studies at CUHK from 2002 to 2006. 

Prof. Chan said, “Students coming from different major programmes have to work as a team to solve the problems in the competition by making use of their programming, communications and problem solving skills. It is definitely a great experience for them to compete with top-tier college students. As a former member of the CUHK programming team, I am also very proud of the students’ achievement.” 

ICPC has become a platform for prestigious international IT enterprises to hire the most outstanding students. Many of the CUHK programming team members have been employed by global IT enterprises such as Google, Apple, Facebook, Microsoft and IBM while some received scholarships to pursue their master or PhD studies in prestigious graduate schools including UC Berkeley, Stanford University, Princeton University, University of Washington, University of Toronto, Brown University, University of Maryland, UCLA, and University of Southern California. The three team members this year, who are all final year students, have received job offers. Yik Wai-Pan and Ho Ngan-Hang have offers from Google, and Poon Lik-Hang will work for a hedge fund.
