Run n times was designed to run several simulations on the same init. When
you select your initialisation method Cormas consider this initialisation
method as the active initialisation method.
This init is activated before the "evolve" method, thus ignoring the n
value.
For your application what you should do I suppose is:
- keep an intilisation method which will be run for each n, iindependent of
the value of n.
- create an new method in "Prepare and schedule"to initialize you parameters
depending on n value, let's say "initparameters: x"
- in your evolve method start with the first instruction
t= 0 ifTrue: [ self initparameters :n].
To test my answer I have implemented an example based on the Pursuit model .
It is attached.
