A Brief Introduction

CUMCM means Contemporary Undergraduate Mathematical Contest in Modeling (for participants from universities/colleges in China Mainland and Macau SAR, the first "C" means China). It is an annual contest for undergraduates all over the world, organized by CSIAM (China Society for Industrial and Applied Mathematics). It has been held annually since 1992. In the year of 2020, 45680 teams (more than 130000 students) from 1470 institutions participated in the contest.

In the contest, up to three students (they must be from the same institution, but it does not matter they are from majors in mathematics or from non-mathematical fields) advised by at most one teacher (optional) form a team. The team's task is to develop in three days mathematical and/or computer models to solve a simplified real-word problem in engineering, management, etc. During the contest days, the students can use any references or materials they can find (including the materials on the INTERNET), but discussions with the advisor or out-of-team members are forbidden. The role of the contest is to improve students' understanding of mathematics, especially mathematical modeling and mathematical software, and to enhance students' motivation for studying mathematics and to cultivate students' creativity and overall ability.

The Awarding system of the contest

The teams are rewarded as first and second prizes with certifications issued by the organizer. All other teams that successfully participate the contest will get certifications of "Successful Participation". All the certifications will be in electronic version (PDF-format files) only, and will be emailed to you after the contest judging is completed.

PLEASE NOTE: Starting from 2019, the "University" level/type teams (i.e., 3-4 years university students) should choose any one from Problems A, B or C;
The "College" level/type teams (i.e., 2-3 years college students only) can choose any one from Problems A, B, C, D or E.

Contest Dates

The contest is organized every year. In each year (starting from 2019), the contest starts on 6:00 PM (Beijing Time) of a Thursday in early-middle September, and ends on 8:00 PM (Beijing Time) of the Sunday followed. There are totally about 72 hours for the contest time (i.e., the first two hours from 6:00PM to 8:00PM for uploading the contest problems are not included in the 72-hour contest time), and each team must upload the solution package before 8:00 AM (Beijing Time) of the Monday followed (i.e., there are 12 hours for the team to upload the solution package).

Registration

Please register by email before the deadline specified on this website (usually two days before the start of the competition) (Only applicable to participants from outside the Chinese Mainland, Hong Kong SAR, and Macao SAR).A team consists of up to three undergraduate students supervised by up to one advisor (optional). All team members must be from the same institution.Please fill in your valid email address, which will be used to receive your electronic participation certificate after the contest.
