Résumé: 

In this talk I will report on some recent developments to particle approximations of transport problems. A first technique is the Forward-Backward Lagrangian (FBL) scheme that computes accurate grid densities based on a reconstructed backward flow. The second development is a local optimization method that improves the particle approximation to better fit the FBL grid density.
