Existence and computation of Berge equilibrium and of two refinements


  • Courtois, Pierre
  • Nessah, Rabia
  • Tazdaït, Tarik


This paper presents existence conditions as well as computation methods for Berge equilibrium and two refinements: Berge–Vaisman equilibrium and Berge–Nash equilibrium. Each equilibrium concept is interpreted and illustrated on the basis of relevant examples and general existence conditions satisfying weak continuity and quasi-concavity conditions are provided.
