populations. The Dunn index and DB index the best values most often are achieved for
FFT and FFD populations.
The best solutions - summary For the selected and analyzed datasets the best solu-
tions relative to β-index have been achieved for CCD and FCD populations. In case of the
Dunn and DB indices, the populations of FFT and FFD performed better.
In this subsection, selected rough indices from analyzed populations have been presented in
graphical form. In Figure 11.3 the values of the best rough index from all 300 populations
have been diagrammatically presented. In the diagram average F2 rough measure as de-
scribed in Table 11.1 in each of the 300 population has been given. From the graph shape
general increasing tendency has been depicted.
