A Sharp Barrier for Consistent Submodular Maximization: Any Improvement over Entails Exponential Queries or Linear Recourse
Shi Fu, Qixin Zhang, Dacheng Tao
Consistent submodular maximization studies the tradeoff between solution quality and stability when elements arrive over time. For a monotone submodular objective, which models dim…
