For problems with noisy or otherwise insufficient data, an optimal solution has slightly different parameter values and sometimes also different structure than the source model. To clarify this for our solutions, Table 2 gives the error of the source model from which data was simulated. We can see that for all problems based on simulated data the found solutions have approximately equal or lower error than that of the source model. We also give the number of FP and FN interactions, to indicate if the found structure is the same as the source model. If the structure is the same as for the source model, we also give the largest deviation (LD) in percent for any parameter compared with the source model. For the problems based on real data, no source model is available, and no such comparisons can be made.
