Abstract:In this paper, we mainly investigate the optimization model that minimizes the cost function such that the cover function exceeds a required threshold in the set cover problem, where the cost function is additive linear, and the cover function is non-monotone approximately submodular. We study the problem under streaming model and propose three bicriteria approximation algorithms. Firstly, we provide an intuitive streaming algorithm under the assumption of known optimal objective value. The intuitive streaming… Show more
