How can we tighten the bounds of the $\ell_1$-norm of $\mathbf{A}x$ where $\mathbf{A}\in\mathbb{Z}^{m\times p}$ and $x \in \{0,1\}^p$?
I am curious about the upper bound of $\|\mathbf{A}x\|_1$ where $\mathbf{A}\in\mathbb{Z}^{m\times p}$ and $x \in \{0,1\}^p$, for a specific $\mathbf{A}$ as defined below.
I know this is an NP-hard ...
