One MDO architecture that has such sound mathematical formulation is augmented Lagrangian co- ordination (ALC), developed by Tosserams et al [2]. This report will discuss the implementation of ALC for quasiseparable problems in the Opensource Multidisciplinary Design Analysis and Opti- mization (...
In this paper, we extend the AKKT conditions to nonlinear optimization on Riemannian manifolds and propose an augmented Lagrangian (AL) method that globally converges to points satisfying such conditions. In addition, we prove that the AKKT and KKT conditions are indeed equivalent under a certain ...
(28), the cross-sectional warping problem can be formulated as a constrained Lagrangian optimization problem. The Lagrange functional reads (30)L=∫Ω0ψ̄(F)+λ⋅ρXˆCS+μ⋅mdX1dX2,where the Lagrange multipliers λ∈R3 and μ∈R4 are defined globally on the domain. Since this ...
