horizontal strategy transmission in Demographic PD

[Anfisa Rekina]

Hy, dear collegues,

First of all, sorry for my english and a silly question (I am an ambitious zero in programming) .

I am working with Epstein,s original code of "Demographic prisoner,s dilemma". His code assumes vertical strategy transmission, while I am also interested in horizontal transmission (an agent compares his payoff with a payoff of a random neighbor after every iterartion, if neighbor,s payoff is higher, agent changes his strategy on the one of neighbor in the next iteration).
Here is what I have done - after an original description of "Play one round of the game with another agent" I have added some code "my art").
And I want to ask you, is it right? does it satisfy what I wanted it to do? There are no errors in Eclipse, and visually there are some changes in a final model in Ascape. But still, I am not qualified enough (at all) to be sure it is right.

// Play one round of the game with another agent.

public void play(Agent partner) {
    if (this.strategy == PD2D.COOPERATE) {
        if (((Player) partner).strategy == PD2D.COOPERATE) {
            this.wealth += ((PD2D) scape.getRoot()).getPayoff_C_C();
            ((Player) partner).wealth += ((PD2D) scape.getRoot()).getPayoff_C_C();

        } else { //partner defects
            this.wealth += ((PD2D) scape.getRoot()).getPayoff_C_D();
            ((Player) partner).wealth += ((PD2D) scape.getRoot()).getPayoff_D_C();}

    } else { //this defects
        if (((Player) partner).strategy == PD2D.COOPERATE) {
            this.wealth += ((PD2D) scape.getRoot()).getPayoff_D_C();
            ((Player) partner).wealth += ((PD2D) scape.getRoot()).getPayoff_C_D();

        } else { //partner defects
            this.wealth += ((PD2D) scape.getRoot()).getPayoff_D_D();
            ((Player) partner).wealth += ((PD2D) scape.getRoot()).getPayoff_D_D();

** // my art!**

            { List neighbors = findNeighborsOnHost();
            for (Object neighbor : neighbors) {
        if (this.wealth < ((Player) neighbor).wealth) {             
            this.strategy = ((Player) neighbor).strategy;}
        }

    }}}
    }
