An Evolutionarily Stable Set (ESS) is a concept from evolutionary game theory that describes a strategy or set of strategies that, if adopted by a population, cannot be invaded or displaced by any alternative strategy that is initially rare. The idea centers around the stability of certain behaviors or traits in a population and how they can endure against competing strategies over time.
