# Metadata - Title: On maximizing a monotone k-submodular function subject to a matroid constraint - Authors: Shinsaku Sakaue - Year: 2016 - Venue: arXiv preprint (`arXiv:1607.07957v3`, August 22, 2016) - Primary group: k-submodular - Secondary tags: matroid, monotone, greedy, constrained-maximization - Problem: monotone k-submodular maximization under a matroid constraint on the support - Main guarantee: a simple greedy algorithm gives a `1 / 2`-approximation for monotone k-submodular maximization subject to a matroid constraint, in `O(M |E| (MO + k EO))` oracle time, where `M` is the basis size - Key techniques: greedy element-label selection, basis exchange inside a matroid, orthant-submodular comparison, monotonicity, and step-by-step hybrid optimal solutions - Status: processed-deep - Tags: #k-submodular #matroid #monotone #greedy #approximation #arXiv - Inbox source: inbox/1607.07957v3.pdf
