We used several algorithms to obtain the most appropriate results. Our analysis comprises nearly all West Palaearctic species and nearly all genera of the Holarctic Aeshnidae and is by far the largest molecular
2.3. Algorithm Validation In order to determine the validity and accuracy of the developed algorithms, both reference and synthetic data sets [34] have been used. These data are the coordinates (x, z) of a series of points linked to a reference profile. The reference data have been obtained...
