Figure 1.

Genes size term in volume evaluation. This figure represent the term $\mathit{\text{Vo}}{l}_g\left(\mathcal{ℬ}\right)=\frac{-ln\left(\right|I\left|\right)}{ln\left(\right|I\left|\right)+w_g}$ in equation 8, for different values of w_g. For smaller values of w_g, Vol_g decreases slower from a smaller value of the number of genes than for greater values of w_g, implying that greater values of w_g should be selected in order to favour major number of genes.
