Fictitious play, Shapley polygons, and the replicator equations. (English) Zbl 0841.90143

Summary: For many normal form games, the limiting behavior of fictitious play and the time-averaged replicator dynamics coincide. In particular, we show this for three examples, where this limit is not a Nash equilibrium, but a Shapley polygon.
