From: Two-stage variable-fidelity modeling of antennas with domain confinement
Procedure of the random trial point rendition for an exemplary dual-band antenna (the objective and parameter space are two- and three-dimensional, respectively). The random designs whose resonant frequencies reside within the required confines of the objective space are retained, the remaining ones are discarded. The inverse regression model sr(⋅) is built using the ultimate trial point set {xr(j)}j = 1,…,Nr.
