N. S. Kukushkin University of Bielefeld, Institute of Mathematical Economics, Working Paper , Nr.307 , 01.1999 , p. 1-25, language: английский  Аннотация Continuing the development of a purely ordinal approach to potential games, we define a strong potential related to coalition improvements and strong equilibrium in the same way as the potential is related to individual improvements and Nash equilibrium. We describe games with perfect information giving rise to potential normal forms. A weaker concept of a semi-potential is introduced, providing an insight into better reply dynamics in models such as games with perfect information and voting by veto.  Ключевые слова potential game, Nash equilibrium, reply dynamics
