Five Elmhurst students advance to finals in international math competition

Team from York Community High School will win a portion of $100,000 in scholarships in MathWorks Math Modeling Challenge

For 14 straight hours in early March, a small group of York Community High School students came together to participate in an international online math competition.

A combination of math smarts and creative thinking has added up to a spot in the finals for the team, whose submission was selected as one of the best solutions to the double whammy crises of affordable housing and homelessness with which local and national governments are currently grappling.

The students — Nick Cifelli, Timothy Flisk, Jeffrey Lu, Taylor Melind, and Steven Piotrowski of Elmhurst-based York Community High School — make up one of the nine finalist teams in MathWorks Math Modeling Challenge (M3 Challenge), a competition that drew nearly 3,000 11th- and 12th-graders in the U.S. and sixth-form students in the United Kingdom this year.

The team, whose work underwent intense scrutiny by judges in the first two rounds of assessment, has one last hurdle when they head to New York City on April 29 to present their findings to a panel of professional mathematicians for final validation.

Using mathematical modeling, students had to come up with solutions to real-world questions: How do we solve the intertwined crises of homelessness and a shortage of affordable housing, especially given that they are often exacerbated by unforeseen circumstances such as natural disasters, humanitarian crises, and economic downturns? Can we predict long-term changes in the housing supply and unhoused population? If so, how can we use this information to devise real, long-term solutions for homelessness?

Now in its 19th year, M3 Challenge is a program of Philadelphia-based Society for Industrial and Applied Mathematics (SIAM) and is sponsored by MathWorks. It spotlights applied mathematics as a powerful problem-solving tool and motivates students to consider further education and careers in applied math, computational and data sciences, and technical computing.

Winning teams will be awarded a share of $100,000 in scholarships, with the champion team receiving $20,000.

A total of 643 teams submitted papers detailing their recommendations. Roughly 45% of those submissions included technical computing to support and enhance their solutions, and those coding skills make them eligible for additional scholarship prizes.

“The cost of housing in the U.S. and the U.K. has increased faster than people’s incomes, making rent or mortgage payments challenging for many,” said Dr. Karen Bliss, senior manager of education and outreach at SIAM. “This issue is often due to a shortage of available housing, which has reached crisis levels and has been associated with a significant increase in homelessness in many large cities.”

“Stable housing can ease homelessness and is often an important first step in helping people tackle other challenges like addiction, mental health issues, and unemployment, but increasing the housing supply is slow and requires significant financial investment,” Bliss said. “There are also other complex issues to consider, such as land restrictions, population growth, financial constraints, and longevity of a housing structure.”

According to Elmhurst team coach and math teacher Ella Sak, the York Community High School students have been dedicated to developing their problem solving skills throughout the year. “I am proud to see them use these skills to solve a real-world problem in M3 Challenge,” she said.

Team member Taylor Melind said that she found M3 Challenge to be instrumental in expanding the team’s problem-solving capabilities beyond conventional boundaries.

“M3 Challenge gave us the opportunity to utilize unconventional problem solving skills and techniques, typically used for abstract data sets and competition problems, for tangible, real-world situations. Through this challenge, we were able to develop our knowledge on one of society’s greatest problems and the possible solutions for it,” Taylor said.

In addition to York Community High School, the other finalist teams hail from schools in Alexandria, Virginia; Andover, Massachusetts; Basking Ridge, New Jersey; Gainesville, Florida; Livingston, New Jersey; Minneapolis, Minnesota; San Diego, California; and Watford, Hertfordshire.
