Cornell Mathematical Contest in Modeling

Short summary: CMCM is an annual university-wide competition for undergraduates (from freshmen to seniors). It attracts students from many majors/departments. Each team of 3 undergraduates works on an open-ended ("real-world") problem, builds a mathematical model, obtains a solution based on it, and writes a detailed paper (proving the feasibility of the team's model and solution) - all this in the space of less than 4 days!
You can: brainstorm with your two teammates, use any reference materials either printed or on the web, write your own software or utilize publicly available to validate your model.
You cannot: consult with anyone besides your teammates, submit your solutions after the deadline, or remain bored in the process.

CMCM is usually conducted in November -- the exact schedule for the current year is posted below. Two to four winning teams are then selected to represent Cornell at the international MCM -- an annual contest conducted in January/February and attracting 15,000+ teams from 20+ countries.

Reasons to participate in CMCM:

• research experience;
• $400+ in prizes every year;
• looks cool on your resume;
• winners of CMCM qualify for the International MCM (thousands of teams, prestigious prizes, looks really cool on your resume).

For those interested:

To subscribe to our mailing list: please send an email to join-cmcm-l@list.cornell.edu

To register your team: If you have already formed a team, you can register it by leaving a comment here.
You can also use the same link to tell other participants that you are looking for a team to join.
Alternatively, you can find team-mates at one of our practice sessions.

Practice sessions (listed below) are very useful -- particularly if this is your first time in CMCM -- please consider attending! If you don't have a full team yet, practice sessions are also a good place to find potential team-mates.

The contest problem & manuscript submission instructions will be posted here on November 8, 2024.

Short instructions for CMCM participants:

• If you have not done so yet, please register your team and join our mailing list (see the instructions above).
• The problem statement will be posted here when the contest starts (at 5pm on 11/8/2024).
• Spend the weekend conducting research, building model(s), and writing up your solution(s).
  All published materials, internet resources, and software are fair game - but don't forget to attribute whenever appropriate.
  You cannot discuss your work with anyone besides your team-mates.
• We follow the same policy as COMAP: the use of AI tools in building the model and writing the manuscript is discouraged, but not forbidden. Beware that ChatGPT & suchlike often spit out confident nonsense and their naive use is unlikely to result in a good model. Any team that uses such tools is required to include an appendix with the full record of your generative AI session (all prompts + all answers that you have received). Not doing this will be viewed as an academic integrity violation & will disqualify your submission. Let's try together to postpone the inevitable irrelevance of the humankind.
• Submit an electronic version of your paper here by 9:30am on Monday (11/11/2024).
  The judges & all CMCM participants will be able to read it & will 'reply' with their comments on your manuscript.
• Don't forget to have fun in the process!

Good luck!

Time-line for 2024-25:

Nov 8, 2024: Cornell MCM starts at 5pm. (The assignment will be posted here.)

Nov 11, 2024: Cornell MCM ends at 9:30am.

Jan 23-27, 2025: The winners of CMCM 2024 represent Cornell at the international MCM 2025.

Modeling problems are selected from all fields of science, engineering, and industry.

A quick note to visitors from outside Cornell University.

The full list of problems used in CMCM:

A few representative problems from the international MCM:

• estimating the maximum "safe" number of people for a given type of public facilities;
• studying hunting strategies for velociraptor dinosaurs based on fossil data;
• comparing various grading policies for fighting the "grade inflation";
• providing the guidelines for selecting the design of bicycle wheels to optimize the performance on a given track;
• considering the effects of different airline overbooking strategies on the overall profitability.

• MCM is not so much about what you already know , but more about what you can learn quickly in the new application area.
• Last year 15,105 teams participated representing institutions from 22 countries.
• It's worth noting that one of Cornell teams won the MCM contest in 2009 (they were ranked among the top 9 teams, all of which were rated "Outstanding") and have received a special award from INFORMS. In 2012 one of Cornell teams got the 2nd highest ranking ("Finalist") and a special award from another sponsor (MAA). Yet another team from Cornell won the related "Interdisciplinary Contest in Modeling" (ICM 2012) -- their solution was ranked "Outstanding" (among the top 7) and they also received a special award from INFORMS.
• We will have two to four teams representing Cornell next year (selected among CMCM winners).
• Several preparation sessions will be held for the potential participants.
