The predator-prey model--based on aspects of the natural interplay of predators and prey--has become an alternative method for tackling multi-objective optimization problems. In this process, each predator targets a single objective, and it is expected that the joint influence of all predators affects the prey population in such a way that good solutions survive. This paper describes PEPPA, a modular software framework for designing and analyzing predator-prey models. It allows to model arbitrary world environments, complex predator behavior and dynamic prey adaptation. Further, PEPPA provides various tools for modeling, visualization and parallelization. We explain the architecture and handling of the framework and provide exemplary results on a simple multi-objective benchmark problem.

Abstract
The predator-prey model--based on aspects of the natural interplay of predators and prey--has become an alternative method for tackling multi-objective optimization problems. In this process, each predator targets a single objective, and it is expected that the joint influence of all predators affects the prey population in such a way that good solutions survive. This paper describes PEPPA, a modular software framework for designing and analyzing predator-prey models. It allows to model arbitrary world environments, complex predator behavior and dynamic prey adaptation. Further, PEPPA provides various tools for modeling, visualization and parallelization. We explain the architecture and handling of the framework and provide exemplary results on a simple multi-objective benchmark problem.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
