On Multiset Selection With Size Constraints

  title={On Multiset Selection With Size Constraints},
  author={Chao Qian and Y. Zhang and K. Tang and X. Yao},
This paper considers the multiset selection problem with size constraints, which arises in many real-world applications such as budget allocation. Previous studies required the objective function f to be submodular, while we relax this assumption by introducing the notion of the submodularity ratios (denoted by αf and βf ). We propose an anytime randomized iterative approach POMS, which maximizes the given objective f and minimizes the multiset size simultaneously. We prove that POMS using a… Expand
