A problem on track runners,
- Adrian Dumitrescu and Csaba D. Tóth,
Consider the unit circle C and a circular arc A of length l=|A|<1. It is shown that there exists k=k(l)∈N, and a schedule for k runners with k distinct but constant speeds so that at any time t ≥ 0, at least one of the k runners is not in A.
