Fair Submodular Cover

CoRR
Submodular optimization is a fundamental problem with many applications in machine learning, often involving decision-making over datasets with sensitive attributes such as gender or age. In such settings, it is often desirable to produce a diverse solution set that is fairly distributed with respect to these attributes.

A hierarchical evolutionary deep reinforcement learning algorithm for influence maximization in multilayer hypergraphs

Frontiers in Physics
Multilayer hypergraphs provide a unified representation of influence diffusion in complex networks by coupling relation layers through shared entities and encoding higher-order group interactions as hyperedges.

Fairness-Aware Opinion Seeding in Undirected Signed Friedkin–Johnsen Networks

Mathematics
Opinion-maximization methods often optimize an aggregate network response and may therefore distribute target-aligned intervention gains unevenly across groups.

Ordinal notions of submodularity

We consider several ordinal formulations of submodularity, defined for arbitrary binary relations on lattices. Two of these formulations are essentially due to Kreps [Kreps, D.M., 1979.

Submodularity and supermodularity in contest games

This paper presents various examples of two-player submodular or supermodular contest games. Emphasizing the three main elements of a contest model, our examples revolve around situations where (i) contest success function allows for a draw, (ii) winning
