Attached are the three toy models used in the book by Grant and Swannack.
The "hunter-gatherer" model (Example 1),
the "population extinction" model (Example 2)
and the "managing the commons" model (Example 3).
Each model has a .sml file with the model in it and a .shf file with the output interface.
This material will form part of an undergraduate course on ecological modelling, to be run at University College Dublin, so any feedback would be very much welcomed.
