Lipschitz continuity conjecture for the convex QCQP reformulation. If the paper's assumptions $Cref{assum:Ab}$ and $ref{assum:main}$ hold and $k>0$, then for every…

Let $\text{\sc Beta}$ denote the convex relaxation of the ball-constrained nonconvex quadratic program defined in the paper, with matrix variable $W$ and vectors $\ell_1,\ell_2$ as…

Let $n$ be a positive integer, let $P_x$ be the region associated with a sign vector $x\in\{-1,+1\}^n$, and let $(C,c)$ be a quadratic-programming input. The preceding proposition…

Let $n$ be the dimension parameter, and let $(C,c)$ be the randomly sampled input used by algorithm. The algorithm repeatedly applies Step. The iteration-bound conjecture. terminat…
