Adaptive Sampling for Fast Constrained Maximization of Submodular Function

no code implementations12 Feb 2021 Francesco Quinzan, Vanja Doskoč, Andreas Göbel, Tobias Friedrich

Our algorithm is suitable to maximize a non-monotone submodular function under a $p$-system side constraint, and it achieves a $(p + O(\sqrt{p}))$-approximation for this problem, after only poly-logarithmic adaptive rounds and polynomial queries to the valuation oracle function.
