Research Type Theoretical We study the deletion robust version of submodular maximization under matroid constraints. The goal is to extract a small-size summary of the data set that contains a high-value independent set even after an adversary deletes some elements. We present constant-factor approximation algorithms, whose space complexity depends on the rank k of the matroid, the number d of deleted elements, and the input precision ε. In the centralized setting we present a (4.494 + O(ε))-approximation algorithm with summary size O( k+d ε ) that improves to a (3.582 + O(ε))-approximation with O(k + d ε ) summary size when the objective is monotone.
