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) | 50.9 | – | − 10.2 | 1.2 | |
Variable resolution (cf. (4)) | p = 1.0 | 25.4 | 50.1 | − 10.5 | 1.0 |
p = 2.0 | 19.5 | 61.7 | − 10.1 | 1.2 | |
p = 3.0 | 17.0 | 66.6 | − 10.3 | 1.4 | |
p = 4.0 | 15.4 | 69.7 | − 10.5 | 1.7 | |
