Algorithm setup | Execution time [hours] | Savings w.r.t. high-fidelity-based algorithm (%) | Average objective function value [dB] | Standard deviation of objective function [dB] | |
|---|---|---|---|---|---|
High-fidelity (L = Lmax) | 31.7 | – | − 15.7 | 2.5 | |
Variable resolution (cf. (4)) | p = 1.0 | 19.6 | 38.2 | − 18.4 | 2.1 |
p = 2.0 | 16.5 | 47.9 | − 17.9 | 1.5 | |
p = 3.0 | 14.5 | 54.3 | − 15.8 | 2.2 | |
p = 4.0 | 13.4 | 57.7 | − 14.0 | 3.0 | |
