Enzo,

Were you able to solve your problem?  Or could you still use assistance?

The usual way to access information in another class when initializing an
object in ECJ is to use the global EvolutionState object to walk through
the program's state and find what you want.

So, in the 'setup()' method of your BusProblemLine class, you would
retrieve the Species object with something like this:

final GeneVectorSpecies species = (GeneVectorSpecies)
state.population.subpops[0].species;
