    • A generally accepted view is that G As are efficient only when the stochastic operators have been adapted to the particular problem under study. It is thus surprising that GAs perform very well in this case generally without any tuning of the stochastic operators.

    • There exist situations when the derivatives are so expensive, either to determine or to implement, that one prefers to avoid them.

    • note
    • Since the function evaluations are so cheap, one may ask why not use them to determine first derivatives through finite difference schemes. To some extent, the strategies we suggest reflect this remark, but only in a loose way. Indeed, calculating gradients often is not attractive in the optimization of highly nonconvex functionals such as the ones expected to exist in general quantum control problems.

    • Inversion of quantum control data is one circumstance in which reducing the number of experiments is of interest. The inversion operations can be far more time consuming than the experiments, and a premium would be placed on the efficiency of the inversion algorithm. In this case the control field would be chosen to reduce the uncertainty in the extracted Hamiltonian information [18,19].

    • This approach is based on the fact that the estimation of the relative ordering between two noisy values converges much more rapidly than the estimation of their difference. This remark is exploited by looking for ordinal rather than cardinal optimization, i.e., concentrating on finding good designs - relative to all possible designs - rather than on accurately estimating (by optimizing directly) the performance value of these designs. The solution obtained will therefore score conveniently in terms of percentile rank among all designs, but its precise performance with respect to the global optimum value is not known in advance.

    • note
    • We also used the modified simplex algorithm on signal averaged surfaces, and we confirmed that it does converge to good quality solutions.
