Table 3. Cross-Validation Results.

15 repetitions	z = 4, ThC = 13	z = 4, no ThC
NRMSE (%)	5.6 ± 1.1	7.4 ± 1.4
$\tilde{E}$ (s)	8.1 ± 1.2	6.9 ± 0.1
$\stackrel{-}{E}$ (s)	9.9 ± 0.6	7.9 ± 0.2
Ep95 (s)	17.6 ± 2.7	14.9 ± 0.2
CR (%)	100	100

Comparison of normalized root mean square error (NRMSE), median efficiency ($\tilde{\mathit{E}}$), mean efficiency ($\stackrel{-}{\mathit{E}}$), 95^th percentile efficiency (E^p95) and completion rate (CR) for the optimal parameters z = 4 Th_C = 13 and z = 4 without Th_C (mean ± standard deviation).
