Abstract

We discuss consistency of vanishingly smooth fictitious play , a strategy in the context of game theory, which can be regarded as a smooth fictitious play procedure , where the smoothing parameter is time dependent and asymptotically vanishes. This answers a question initially raised by Drew Fudenberg and Satoru Takahashi.
