Though ubiquitous in our daily lives, crumpling is a challenging process to understand and predict: As a thin sheet is confined, stresses spontaneously localize to produce a complex network of vertices and ridges in the sheet. However, past studies have uncovered surprising mathematical order to the length of creases that form as a sheet is crum...

The Burer-Monteiro method is one of the most widely used techniques for solving large-scale semidefinite programs (SDP). The basic idea is to solve a nonconvex program in Y, where Y is an n×p matrix such that X = YYT. We show that this method can solve SDPs in polynomial time in a smoothed analysis setting. More precisely, we consider an S...
