2013 Mathematical Contest in Modeling® Press Release—April 5, 2013 COMAP is pleased to announce the results of the 29th annual 2. Maximize even distribution of heat (H) for the pan Mathematical Contest in Modeling (MCM). This year, 5636 teams 3. Optimize a combination of conditions (1) and (2) where weights p and representing institutions from fourteen countries participated in the contest. (1- p) are assigned to illustrate how the results vary with different values of Eleven teams from the following institutions were designated as W/L and p. OUTSTANDING WINNERS: In addition to your MCM formatted solution, prepare a one to two page Beijing Univ. of Posts and Telecomm, China advertising sheet for the new Brownie Gourmet Magazine highlighting Bethel University, Arden Hills, MN your design and results. Colorado College, Colorado Springs, CO Fudan University, China The B problem was authored by Professor Dave Olwell, entitled “Water, Nanjing University, China Water, Everywhere”. Fresh water is the limiting constraint for development Peking University, China in much of the world. Build a mathematical model for determining an Shandong University, China effective, feasible, and cost-efficient water strategy for 2013 to meet the Shanghai Jiaotong University, China projected water needs of [pick one country from the list below] in 2025, Tsinghua University, China and identify the best water strategy. In particular, your mathematical model University of Colorado Boulder, Boulder, CO (2) must address storage and movement; de-salinization; and conservation. If possible, use your model to discuss the economic, physical, and This year’s contest ran from Thursday, January 31 to Monday, February 4, environmental implications of your strategy. Provide a non-technical 2013. During that time, teams of up to three undergraduate or high school position paper to governmental leadership outlining your approach, its students researched, modeled, and submitted a solution to one of two feasibility and costs, and why it is the “best water strategy choice.” modeling problems. The 2013 MCM was primarily an online contest. Countries: United States, China, Russia, Egypt, or Saudi Arabia Teams registered, obtained contest materials, and downloaded the problem and data at the prescribed time through COMAP’s MCM Website. The eleven Outstanding solution papers will be featured in The UMAP Journal, along with commentary from the authors and other judges. All This year the two MCM problems represented significant challenges. The 5636 of the competing teams are to be congratulated for their excellent author of the A problem is Veena Mendiratta. The problem was “The work and enthusiasm for mathematical modeling and interdisciplinary Ultimate Brownie Pan”. problem solving. When baking in a rectangular pan heat is concentrated in the 4 corners and the product gets overcooked at the corners (and to a lesser extent at the 2013 MCM Statistics edges). In a round pan the heat is distributed evenly over the entire outer edge and the product is not overcooked at the edges. However, since most ovens are rectangular in shape using round pans is not efficient with respect • 5636 teams participated to using the space in an oven. Develop a model to show the distribution of • 4 high school teams (1%) heat across the outer edge of a pan for pans of different shapes - rectangular • 375 US Teams (7%) to circular and other shapes in between. • 5261 Foreign Teams (93%) from Canada, China, Finland, Germany, Hong Kong, India, Indonesia, Mexico, Malaysia, Assume Singapore, South Korea, Sweden, United Kingdom 1. A width to length ratio of W/L for the oven which is rectangular in shape. • 11 Outstanding Winners (1%) 2. Each pan must have an area of A. • 13 Finalist Winners (1%) 3. Initially two racks in the oven, evenly spaced. • 858 Meritorious Winners (15%) • 1650 Honorable Mentions (29%) Develop a model that can be used to select the best type of pan (shape) • 3094 Successful Participants (55%) under the following conditions: 1.

Major funding for the MCM is provided by COMAP. Additional support is provided by the Institute for Operations Research and the Management Sciences (INFORMS) and Two Sigma Investments. COMAP's Mathematical Contest in Modeling and Interdisciplinary Contest in Modeling are unique among modeling competitions in that they are the only international contests in which students work in teams to find a solution. Centering its educational philosophy on mathematical modeling, COMAP uses mathematical tools to explore real-world problems. It serves the educational community as well as the world of work by preparing students to become better informed—and prepared—citizens, consumers, and workers.
