      abstract = {In a haystack-type representation of a heterogeneous  population that is evolving according to a payoff structure  of a prisoner’s dilemma game, migration is modeled as a  process of “swapping” individuals between heterogeneous  groups of constant size after a random allocation fills the  haystacks, but prior to mating. Migration is characterized  by two parameters: an exogenous participation-in-migration  cost (of search, coordination, movement, and  arrangement-making) which measures the migration effort,  and an exogenous technology - of coordinating and  facilitating movement between populated haystacks and the  colonization of currently unpopulated haystacks - which  measures the migration intensity. Starting from an  initially heterogeneous population that consists of both  cooperators and defectors a scenario is postulated under  which “programmed” migration can act as a mechanism that  brings about a long-run survival of cooperation.},
