Center hyperedge (induced by source paper "tight space approximation tradeoff for the multi pass streaming set cover problem"):
  Abstract: We study the classic set cover problem in the streaming model: the sets that comprise the instance are revealed one by one in a stream and the goal is to solve the problem by making one or few passes over the stream while maintaining a sublinear space $o(mn)$ in the input size; here $m$ denotes the number of the sets and $n$ is the universe size. Notice that in this model, we are mainly concerned with the space requirement of the algorithms and hence do not restrict their computation time. #R##N#Our main result is a resolution of the space-approximation tradeoff for the streaming set cover problem: we show that any $\alpha$-approximation algorithm for the set cover problem requires $\widetilde{\Omega}(mn^{1/\alpha})$ space, even if it is allowed polylog${(n)}$ passes over the stream, and even if the sets are arriving in a random order in the stream. This space-approximation tradeoff matches the best known bounds achieved by the recent algorithm of Har-Peled et.al. (PODS 2016) that requires only $O(\alpha)$ passes over the stream in an adversarial order, hence settling the space complexity of approximating the set cover problem in data streams in a quite robust manner. Additionally, our approach yields tight lower bounds for the space complexity of $(1- \epsilon)$-approximating the streaming maximum coverage problem studied in several recent works.
