Thus, by exploring the space of geometric parameters by genetic algorithm, we can modify the shapes of moving objects, to optimize their drag and lift force.

The modification of the shape of a front spoiler, in automotive external aerodynamics, is an example of reducing energy consumption on the motorway. The increase in pressure on the tailgate window, by regulating the underbody flow, results in a recoil or a suppression of the vortex downstream of the rear bumper.

The algorithm presented below shows the possibility of integrating acoustic optimization criteria with this same method.
