Sparse covers for sums of indicators

For all \(n, \epsilon >0\), we show that the set of Poisson Binomial distributions on \(n\) variables admits a proper \(\epsilon \)-cover in total variation distance of size \(n^2+n \cdot (1/\epsilon )^{O(\log ^2 (1/\epsilon ))}\), which can also be computed in polynomial time. We discuss the implications of our construction for approximation algorithms and the computation of approximate Nash equilibria in anonymous games.
