   Social behavior is an example of a complex system. Complex systems are typically characterized by multiple interacting components, commonly resulting in nonlinear outcomes. These systems are challenging to analyse using standard linear approaches, but are naturally modeled using Agent Based Models. ABMs are increasingly common in behavioral studies, but principled methods for fitting models to empirical data are needed. Here, we fit behavioral genetic parameters to empirical results of complex group formation in Drosophila melanogaster.
