Individual-based simulation of hawk-dove game

Hi all,

I am doing an individual-based simulation of the continuous hawk-dove game using the subpopulation model to model individual reproduction and mortality and the inheritance model to deal with genetic inheritance and mutation. For each individual I calculate the payoff of a focal individual (payoff) and the payoff for a random interactant (payoffopponent). All this I got working. But now I would like to let each individual reproduce if its payoff is higher than that of an interactant (payoff>payoffopponent), and after that I would like to let all parents die. If the payoff is the same as the payoff of the opponent it should reproduce with a 50% chance. Does anyone know how I should specify the reproduction and destruction processes then in the subpopulation model? Also, which one is evaluated first, reproduction of destruction/mortality, because in general the order in which things are evaluated matters in discrete time models?

Anyway, any help with this would be much appreciated!

cheers,
