✦ Synopsis

The aim of this paper is to present and discuss the used of genetic algorithms and geometric modeling by means of -splines surface representation in order to solve tri-dimensional shape optimization problems. Genetic algorithms have demonstrated to be a very robust search tool that models the evolution in arti"cial creatures. On the other hand, -spline surface representation allows a very simple description on a high level of abstraction, and it is well suited to capture interactive in#uence. Other advantages are the validity of the shape description for large changes and the possibility of to generate optimal meshes. Finally, a numerical example is presented and discussed in order to show the great applicability of the developed tool.
