Simple Randomized Rounding for Max-Min Eigenvalue Augmentation

We consider the *max-min eigenvalue augmentation* problem: given $n \times n$ symmetric positive semidefinite matrices $M,A_1,\ldots, A_m$ and a positive integer $k < m$, the goal is to choose a subset $I \subset \{1,\ldots,m\}$ of cardinality at most $k$ that maximizes the minimum eigenvalue of the…
