| 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. |

| Abstract | Augmented Lagrangean Relaxation Method (ALRM) is one of the most powerfull technique to solve the ShortTerm Hydrothermal Coordination Problem (STHC Problem ). A crucial step when using the ALR Method is the multipliers updating. In this paper we present an efficient new multiplier updating procedure: the Gradient Method with Radar Step. The method has been successfully tested solving large scale exemples of the STHC Problem |

| Abstract | The NOXCB package is an optimization code for the Nonlinear Network flow problem with Linear side Constraints (NNLC). It is based on an active set method which exploits the network structure through primal partitionning techniques. This paper presents the results arising from the solution of a set of about 100 (NNLC) problems, ranging from medium to large scale. |
