exchange of individuals between subpopulations. Migration is used in the regional population model. The spread of information among subpopulations is influenced by the migration topology (i.e., which subpopulations exchange individuals?), the migration interval (i.e., how often does an exchange take place?), and the migration rate (i.e., how many individuals are exchanged?). These parameters determine whether the subpopulations evolve in a relatively independent way or rather behave like a panmictic population.
