  1. The CPU time is normalized using the Linpack benchmark table and is in case of the multistarts of the single shooting (SS) and multiple-shooting (MS) method the sum over all restarts. As in the case of the STAT5 example the improved robustness of multiple-shooting gives rise to increased computational cost compared to single shooting. The benefit of the hybrid becomes evident by the fact that the computational cost of the hybrid is about 8 times lower than DE for the Box 5, 60 times lower for the Box 10 and around 40 for Box 100.
