abstract = "In this paper we present a study that analyses the
respective advantages and disadvantages of the
synchronous and asynchronous versions of island-based
genetic programming. We also look at different
measuring systems for comparing parallel genetic
programming with panmitic model. At the same time we
show an interesting relationship between the bloat
phenomenon and the number of individuals we use.
Finally, we study a relationship between the number of
subpopulations in parallel GP and the advantages of the
asynchronous model.",
