sci.evolutionary-stable-strategy Calculator
Calculates the Evolutionarily Stable Strategy (ESS) for the Hawk-Dove game from payoff matrix values and the mixed-strategy ESS frequency. ESS hawk frequency = V/C where V is resource value and C is injury cost — when V < C, a mixed ESS exists; when V > C, all-hawk is the ESS.
Inputs
V Value
Reference formula or conversion factor shown for context.
C Cost
Reference formula or conversion factor shown for context.
Results
ESS proportion of Hawks
Sample size or count used in the calculation.
ESS proportion of Doves
Sample size or count used in the calculation.
average payoff at ESS (Hawk)
The arithmetic mean -- sum divided by count.
average payoff at ESS (Dove)
The arithmetic mean -- sum divided by count.
ESS Hawk freq = V/C (if V<C)
