Short-step Methods Are Not Strongly Polynomial-Time

Optimization and Control 2022-01-11 v1

Abstract

Short-step methods are an important class of algorithms for solving convex constrained optimization problems. In this short paper, we show that under very mild assumptions on the self-concordant barrier and the width of the 2\ell_2-neighbourhood, any short-step interior-point method is not strongly polynomial-time.
