nash equilibrium
some ratio of both hawks & doves
no individual has an incentive to change its strategy because no other options yields a better overall cost-benefit analysis
what ESS is overall most effective?
nash equilibrium
what ESS is most effective in a population of mostly doves?
to be a hawk (easy to steal/ be aggressive)
what ESS is most effective in a population of mostly hawks?
to be a dove (no cost in losing)
if there is only one encounter, which ESS is most effective?
mathematically, hawk (offers highest energy payoff)
