Global Optimization Algorithms in Multidisciplinary Design Optimization [PDF]
12th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2008 While Multidisciplinay Design Optimization (MDO) literature focuses mainly on the development of different formulations, through the manipulation of design variables, less attention is generally devoted to the combination of specific MDO formulations with existing nonlinear optimization algorithms.

Riemannian optimization and multidisciplinary design optimization [PDF]
Optimization and Engineering, 2016 Riemannian Optimization (RO) generalizes standard optimization methods from Euclidean spaces to Riemannian manifolds. Multidisciplinary Design Optimization (MDO) problems exist on Riemannian manifolds, and with the differential geometry framework which we have previously developed, we can now apply RO techniques to MDO.

Interaction Prediction Optimization in Multidisciplinary Design Optimization Problems [PDF]
The Scientific World Journal, 2014 The distributed strategy of Collaborative Optimization (CO) is suitable for large-scale engineering systems. However, it is hard for CO to converge when there is a high level coupled dimension. Furthermore, the discipline objectives cannot be considered in each discipline optimization problem.
