abstract = "A black box model is a numerical simulation that is
used in optimisation. It is computationally expensive,
so it is convenient to replace it with surrogate models
obtained by simulating only a few points and then
approximating the original black box. Here, a recent
approach, using Symbolic Regression via Genetic
Programming, is compared experimentally to neural
network based surrogate models, using test functions
and electromagnetic models. The accuracy of the model
obtained by Symbolic Regression is proved to be good,
and the interpretability of the function obtained is
useful in reducing the optimisation's search space.",
