Why your next date might be decided by an algorithm
In short: Mathematics is often associated with cold calculations, but it also governs the messy dynamics of human romance. From assigning university housing to pairing people for dates, non-numerical mathematical algorithms provide the framework for finding stable matches in a complex world.
While many view mathematics as a tool for high-stakes engineering—such as flying aircraft, executing financial transactions, or designing racing cars—it is equally adept at solving logistical human problems. Professor Tony Mann explores how these techniques can be applied to social structures, specifically in determining how computer dating agencies can most effectively pair off their clients. These non-numerical mathematical algorithms are presented in simple terms for public understanding. Gresham College has hosted free public lectures since 1597 to share such knowledge.
The core challenge lies in creating 'stable' matches. This involves finding a balance where individuals are paired in a way that satisfies specific preferences or constraints. These same mathematical principles are used in other organizational settings, such as assigning students to university halls of residence or matching workers to available employment vacancies. By using non-numerical algorithms, computers can navigate these multi-variable problems more efficiently than human intuition alone. The lecture series began on February 17, 2014. These methods help manage complex systems where multiple preferences must be balanced simultaneously.
The intersection of math and romance is often met with skepticism due to the public perception of mathematicians as being unromantic. Mann notes that popular culture has even suggested avoiding mathematicians in romantic pursuits entirely. However, he argues that the underlying logic of mathematics is inherently valuable for understanding love. He illustrates this by showing a heart shape described by the equation (x2 + y2 – 1)3 – x2y3 = 0, suggesting that romance and mathematical structure are not mutually exclusive but deeply intertwined. Mann references a specific book that lists mathematicians as the top profession to avoid in romance. He also uses the Möbius strip as a physical demonstration of mathematical properties.
