Performance Bounds for Nash Equilibria in Submodular Utility Systems with User Groups
Yajing Liu, Edwin K. P. Chong, Ali Pezeshki
In this paper, we consider variations of the utility system considered by Vetta, in which users are grouped together. Our aim is to establish how grouping and cooperation among use…
