In the following empirical study, the survivability of diverse individuals are studied to understand the guiding forces in search. The phrase diverse individuals refers to those individuals in the population that account for the majority of dissimilarity. These individuals are found by comparing their average dissimilarity to the population's average dissimilarity. Following this study, many adjustments may be possible to improve efficiency or performance. Additionally, there is another important motivation for studying the survivability of diverse individuals in standard genetic programming populations: the role of the migrant in distributed models. Generalising these results to describe the expected behaviour of migrants in a distributed model is not a stretch of applicability. Distributed models are commonly defined in a way to mimic several single population runs with periodic exchange of individuals. The following study, which also considers the most dissimilar individuals as migrants, is probably being conservative as migrants are likely to be much more dissimilar in real distributed models. Next, the genetic outlier definition and the measure of survivability are described.
