Shallit Constant
Summary
The Shallit constant is a mathematical constant that arises from an optimization problem involving a function of positive numbers and the reciprocals of their consecutive products. As the number of variables grows, the smallest possible value of this function approaches the expression $3n − C$, where $C ≈ 1.369451403937$ is the Shallit constant. This means that the constant represents the fixed correction term in the asymptotic behavior of the minimum value, revealing a surprisingly stable pattern hidden within an increasingly complex optimization problem.
The constant was introduced by Jeffrey Shallit in 1995 through a problem published in SIAM Review, where a solution by C. C. Grosjean and H. E. De Meyer significantly simplified the analysis. Although the Shallit constant is not as widely known as famous constants such as π or e, it is an elegant example of how deep mathematical constants can emerge naturally from optimization and asymptotic analysis.
