In parametric shape optimization, results usually depend on the choice of the parameterization. In order to reduce this critical dependency, a self-adaptive parameterization methodology is developed, that adapts an initial and perhaps naïve parameterization to the problem studied, on the basis of a first approximation of the optimum shape. The proposed approach is studied in the framework of the Bézier curve representation and the Free-Form Deformation (FFD) approach. It is first applied to a geometrical arc reconstruction problem and then to a three-dimensional shape optimization problem in aerodynamics.
