Video Tutorials
Wherever you see the
eye icon
on this site,
it is a link to a video tutorial.
You can download a copy of the completed model here.
Using your model, try out some of the following:
- Try altering the starting population. (You could add in
another slider for initial population if you like.) Are the devils
more likely to become extinct if the initial population is larger or
smaller?
- Try adjusting the speed the devils move around (Make the forward
steps 0.5 instead of 1). What difference does this make to the
spread of the disease?
- Try altering the territory size. Does the disease spread
faster if the territories are smaller or larger?
- Under what conditions can some devils survive?
- Alter the rate at which the Devils die after infection. What difference does it make?
Think of a question of your own that you could use your model to answer.
In what ways is your model different from the situation of Devils in the real world? What factors are missing that might be important?
Extension
Add in a Devil breeding program, so that healthy Devils can reproduce. You can get some ideas about how to set up breeding from the Fish and Plankton example that comes packaged with Starlogo TNG.
