Exploring the relation between translayer ratio and ${\overline{F}}_0$ and $\overline{\text{SPL}}$ for a three layer vocal fold based on solutions from 500 generations of NSGA-II algorithm. (a, b) Scatter plots of ${\overline{F}}_0$, $\overline{\text{SPL}}$ across ${{\mu }^{\prime }}_2/{{\mu }^{\prime }}_1$. (c, d) Cluster plots of ${\overline{F}}_0$, $\overline{\text{SPL}}$ across ${{\mu }^{\prime }}_2/{{\mu }^{\prime }}_1$.
