Majorizing Measures for the Optimizer

no code implementations24 Dec 2020 Sander Borst, Daniel Dadush, Neil Olver, Makrand Sinha

In this paper, we return to majorizing measures as a primary object of study, and give a viewpoint that we think is natural and clarifying from an optimization perspective.

On the Integrality Gap of Binary Integer Programs with Gaussian Data

no code implementations15 Dec 2020 Sander Borst, Daniel Dadush, Sophie Huiberts, Samarth Tiwari

For a binary integer program (IP) ${\rm max} ~ c^\mathsf{T} x, Ax \leq b, x \in \{0, 1\}^n$, where $A \in \mathbb{R}^{m \times n}$ and $c \in \mathbb{R}^n$ have independent Gaussian entries and the right-hand side $b \in \mathbb{R}^m$ satisfies that its negative coordinates have $\ell_2$ norm at most $n/10$, we prove that the gap between the value of the linear programming relaxation and the IP is upper bounded by $\operatorname{poly}(m)(\log n)^2 / n$ with probability at least $1-2/n^7-2^{-\operatorname{poly}(m)}$.

The Gram-Schmidt Walk: A Cure for the Banaszczyk Blues

1 code implementation3 Aug 2017 Nikhil Bansal, Daniel Dadush, Shashwat Garg, Shachar Lovett

An important result in discrepancy due to Banaszczyk states that for any set of $n$ vectors in $\mathbb{R}^m$ of $\ell_2$ norm at most $1$ and any convex body $K$ in $\mathbb{R}^m$ of Gaussian measure at least half, there exists a $\pm 1$ combination of these vectors which lies in $5K$.
