## The results of 2019 MCM have been announced. Six
teams from CAS-JXUST achieve 2 Honorable Mentions and 3 Successful Participants.

#### The Mathematical Contest in
Modeling (MCM) is a multi-day mathematics competition held annually in
USA, during the first or second weekend in February, since 1985 by COMAP and sponsored by SIAM, the NSA, and INFORMS.
It is distinguished from other major mathematical competitions such as Putnam
by its strong focus on research, originality, teamwork, communication and
justification of results. It runs concurrently with the Interdisciplinary Contest in Modeling (ICM).
At the beginning of the contest, teams have a choice between two problems.
Problem A involves a system that requires the use of continuous mathematics,
and thus often involves concepts from geometry, physics, or engineering.
Problem B involves a system that requires the use of discrete mathematics. In 2016, a
"data insights" problem was added, where teams are given access to
database files and tasked with using them to answer a question. This problem
was designated as Problem C, though previously, Problem C referred to an ICM
problem. These problems tend to be open-ended, and are drawn from all fields of
science, business, and public policy. Thousands of international teams of three
undergraduates compete to produce original mathematical papers in response to
one of two modeling problems. Initially, participation was largely from the
United States, however in recent years international participation has grown
significantly, particularly from the People's Republic of China, so that in
2007 teams from the United States comprised only 24% of total participation. In
2014, the percentage of teams from the People's Republic of China reached a
record high of 92.9%.
