That idea of a Nash equilibrium is very interesting. I wonder if there really are multiple Nash equilibriums for many systems. At least in the prisoner example the article talked about it seemed more like there is a single optimal N.E. and it only changed once the circumstances/system changed

Equilibria concepts in game theory are many and varied. A system may have many Nash Equilibria, in mixed strategies and in pure strategies. Nash equilibria are where no one player has an incentive to deviate from their current strategy.

Game theory is a fascinating topic I highly encourage interested folks to investigate.
