Characterization of the equilibrium strategy of the bimatrix game with fuzzy payoff. (English) Zbl 0974.91004
This paper deals with bimatrix games with fuzzy payoff matrices. Two concepts of Nash equilibrium strategies are introduced and their properties are investigated. Finally the author gives an existence theorem of these Nash equilibrium strategies in any bimatrix game with fuzzy payoff.
