Fig. 3.

The performance of OCTAL and ASTRAL-II across three levels of ILS evaluated under three tree distance metrics. Each subfigure shows the performance of OCTAL in red (using ASTRID as the reference tree) and ASTRAL-II in blue under one of three distance metrics. Under each distance metric, a lower value indicates the estimated completed tree is closer to the true gene tree. The median distance is reported above each boxplot, and so the outliers are not shown. OCTAL shows the largest improvement over ASTRAL-II under the moderate ILS condition in each case
