CSSO is that subspace optimization is not carried out in BLISS.

9.3 MDO Framework

Different MDO architectures were presented in the previous section. One

question that arises here is, how do we know which architecture is more ef-

cient? To answer this, one needs a platform in which different MDO archi-

tectures can be compared. The MDO framework provides this platform. The

MDO problem is rst input in standard form. The user then has to select the

architecture through which the problem needs to be solved. The framework

then casts ...
