| Abstract | Recents numerical experiments show that the resolution of the
Nonlinear network Flow problem with side Constraints (NFC) can
be significantly sped up, when the side constraints are linear,
by specialised codes based on a conjunction of primal partitioning
techniques and active set methods. A natural extension of these methods
one is to be used into a Projected Lagrangian Algorithm (PLA). A specialised
(PLA) will solve the general (NFC) problem through the optimization
of a sequence of (NFC) with linear side constraints, taking benefit
of the efficiency of the linear side constraints codes. The description of
this methodology will be presented together with the preliminary
numerical results. |
