A Nash equilibrium strategy does not assume that an opponents strategy never changes. A Nash equilibrium has the property that if the opponents strategy deviates from a Nash equilibrium, then the opponent will lose.
- xapata 10y agoThat's neither my memory of the phrase from school nor my reading of the Wikipedia article. Nash equilibrium may not exist if one of the players follows, say, a Markov switching process. If that process causes the opponent to stop seeking equilibrium or to settle into a false equilibrium, then the switching process may have been a better strategy than seeking equilibrium.
