Inseparables: exact potentials and addition


  • Nikolai S. Kukushkin

    () (Dorodnicyn Computing Centre, FRC CSC RAS; Moscow Institute of Physics and Technology)


In both universal classes of exact potential games described in the existing literature, congestion games and games with structured utilities, the players sum up their common local utilities. This paper shows that no other method to aggregate local utilities could guarantee the existence of an exact potential.
