Integrating niching into the predator-prey model using epsilon-constraints
Christian Grimme, Joachim Lepping · 2011
The Predator Prey Model (PPM) for multi-objective evolutionary optimization features a simple abstraction from natural species interplay: predators represent different objectives and collectively hunt for prey solutions which have to adapt to all predators in order to survive. In this work, we start from previous insights to motivate significant changes in predators by enabling adaptation of selection behavior. For this, we integrate aspects of the ε-Constraint method into the PPM mechanisms. Our results show that this model extension results in good Pareto-fronts for bi-objective test problems.
