Question: What is the purpose of the model?
There are 11 design concepts.
Textbook has one chapter for each.
What is the initial state of the model world?
Time \(t = 0\) of a simulation run
Does the model use input from external sources
(data files, other models, human interaction)
to represent processes that change over time?
If so, what data?
Where did they come from?
Provide references, citations.
If the process scheduling step contains a list of processes,
explain, in detail what submodels represent those processes.
What are the model parameters?
How were the submodels designed or chosen?
How were they tested?

Ecologists observe that as butterflies move uphill, they concentrate into narrow and well-definied virtual corridors rather than following any old path to the top of the hill.
Explore the concept of virtual corridors:
Can concentrations of migrating animals emerge spontaneously from movement behavior and topography, instead of being a special habitat?
