 **Nota bene**: All PoissonGroups share the same random number generator which is seeded by default the same for each run of a simulation. To create differnt runs it has to be seeded randomly using the ''​seed''​ function. **Nota bene**: All PoissonGroups share the same random number generator which is seeded by default the same for each run of a simulation.

 To seed the random number generator shared by all [[PoissonGroups]] the function ''​seed(int s)''​ has to be called. Rate changes can be implemented by calling the method ''​set_rate(rate)''​ where ''​rate''​ is given in Hertz. Regular re-setting of the rate will impair the performance of the PoissonGroup. To seed the random number generator shared by all [[PoissonGroups]] the function ''​seed(int s)''​ has to be called.
