Fig. 5

Maximum/minimum values of studied quantities corresponding to best performance. The minimum achieved values of \(\left\langle {f_{MEI} } \right\rangle\) for all clustering strategies with combination of \(D_{1}\) or \(D_{2}\) values are visualized on sub-figures (a) and (b), the maximum achieved values of \(\left\langle {N_{ic} } \right\rangle\) are visualized on sub-figures (c) and (d), the minimum achieved values of \(\left\langle s \right\rangle\) are visualized on sub-figures (e) and (f) and the maximum achieved values of \(f_{HWeq}\) are visualized on sub-figure (g)
