- Addresses a problem posed by Shub and Smale in 1993
- Advances understanding of polynomial condition numbers

## Abstract

We find an explicit sequence of univariate polynomials of arbitrary degree with optimal condition number. This solves a problem posed by Michael Shub and Stephen Smale in 1993.
