Assigning Entities to Teams as a Hypergraph Discovery Problem
Guilherme Ferraz de Arruda, Wan He, Nasimeh Heydaribeni +3
We propose a team assignment algorithm based on a hypergraph approach focusing on resilience and diffusion optimization. Specifically, our method is based on optimizing the algebra…
