Optimization voronoi diagram galapagos

Hi guys,
I carried out an optimization through Galapagos where I put as genomes the subdivisions and the strength and as fitness the minimization of nodal displacements.
I think there is something wrong because the simulation runs but I suppose that the results are not reliable due maybe to the fact that the subdivision is not directly connected in the Galapagos simulation (as you can see, Voronoi is successively applied on the mesh).
My aim is to optimize the Voronoi subdivision and improving its structural performance but as it is applied to my shell, it really does not influence my simulation.

Any kind of suggestion/correction is really appreciated.

Thanks a lot,

Did I write in a wrong place?
Anyway thank you
