We consider an evolutionary method applied to a topology optimization problem. We compare two material distribution formalisms (static vs. Voronoi-based dynamic), and two sets of reproduction mechanisms (standard vs. topology-adapted). We test those four variants on both theoretical and practical test cases, to show that the Voronoi-based formalism combined with adapted reproduction mechanisms performs better and is less sensitive to its parameters.
