PSYC 472 Lecture Notes - Lecture 5: Sexual Reproduction, Inclusive Fitness, Nash Equilibrium
Document Summary
Using the rare strategy is more successful (you try to do what no one else is doing) Equilibrium when an equal number of people are using each strategy so whichever strategy you use it doesn"t matter (any strategy change will not give you an advantage) this is what nash equilibrium is. Mean payoff from hawk strategy=probability of hawk meeting*payoff vs. hawk + probability of meeting dove*payoff vs. dove. Mean payoff from dove strategy=probability of meeting hawk*payoff vs. hawk + probability of meeting dove*payoff vs. dove. Stable equilibrium will depend on the populations of hawks and doves (if there are equal amounts of each, etc. ) Self is always more related to self than to siblings. Hungry baby bird"s first worm is worth more than the second worm (law of diminishing returns) So mama gets more benefits by giving each baby bird one worm than one two and the other none.
