Abstract
Both continuous and discrete sensititivites and gradient evaluations carry important information in the building of an optimal shape loop. This is particularly true for the smoothness of objective functionals and the functions representing their gradients. The main application addressed here is the choice of a preconditioner for the optimisation loop.


Résumé
Gradient continu, gradient discret, tous deux nous apportent des informations importantes pour les boucles de conception optimale de forme, notamment en ce qui concerne la régularité des fonctionnelles et des fonctions constituées par leur gradients. La principale application présentée est le choix d'un préconditionneur pour la boucle d'optimisation.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
