# Evolutionarily Stable Strategy It’s like a Nash equilibrium but arrived at and enforced not by people thinking “ah this is the best strategy” but through evolutionary mechanisms where any incremental change is less ‘fit’ No mutant strategy can invade Note that it explicitly depends on a population and environment.
