Depending on the noise model that is assumed to underlie the data acquisition, these optimization problems may be non-smooth. Another source of lack of smoothness (differentiability) of the cost function may arise from the regularization method chosen to handle the ill-posed nature of the inverse...
Entering into the mathematical details of numerical optimization would lead us too far astray. For concreteness, the next sections address in a qualitative fashion some practical issues that anyone dealing with maximum likelihood algorithms should be aware of. After discussing these issues, we will pro...

the accuraciesof the surrogate models are calculated to determine whether the model can be used for the following optimization design. If the model accuracy cannot satisfy the optimization requirements, new samples will be obtained by sequential sampling algorithms to improve the surrogate model until...
