Parallelization is becoming a more and more important issue for solving difficult optimization problems. Various implementations of parallel evolutionary algorithms (EAs) have been applied in the past decades. Island models combine phases of independent evolution with migration where genetic information is spread out to neighbored islands. Compared to panmictic models, this mechanism can lead to an increased diversity within the population. We perform a first rigorous runtime analysis for island models and construct a function where phases of independent evolution as well as communication among the islands is essential. A simple island model with migration finds a global optimum in polynomial time, while panmictic populations as well as island models without migration need exponential time, with very high probability. Our results lead to new insights on the usefulness of migration and contribute to the theoretical foundation of parallel EAs
