“…As we shall see later on, this case of saddle-point problems appears to be a very specific case where the magnitude of the off-diagonal terms can be, in some sense, arbitrarily large and where the (positive or negative) monotony of the block-diagonal terms is sufficient to prove convergence of algorithms such as those of Uzawa, Arrow-Hurwicz or other more general algorithms (Ref. 2).…”

“…System y computes a movement direction for problem (A.5), using Newton's method, Problem (A1)-(A3) has also been solved using a Lagrangian relaxation procedure [16] and an augmented Lagrangian relaxation one [3,7]. The Lagrangian relaxation procedure uses a simple subgradient updating of multipliers, and the augmented Lagrangian decomposition procedure uses a progressively increasing penalty term and a simple gradient multiplier updating technique.…”

“…Particularly remarkable is the theoretical decomposition framework based on the auxiliary problem principIe ana1yzed in [6][7][8]. An application ofLagrangian relaxation to solve a multi-area OPF is described in [1,9], while in [2,14] an augmented Lagrangian relaxation procedure is used to sol ve a distributed OPF.…”

“…S orne authors replaced the classical metric by a nonlinear fixed metric, based on an entropie method (G. Chen and M. Teboulle [4], J. Eckstein [7], S. Kabbadj [8], ...). Others let the metric change at each itération (G. Cohen [5] and [6], M. Qian [11] and [12], J. R Bonnans, J. C. Gilbert, C. Lemaréchal and C. Sagastizabal [3], A. Renaud [13], ...).…”
