Table 1 The number of gene trees for which OCTAL provided an improvement over ASTRAL-II, for which ASTRAL-II provided an improvement of OCTAL, and for which there was no difference between the two methods is provided below for three levels of ILS and three evaluation distance criteria

  1. The RF, matching, and quartet distances are used for evaluating the distance between the completed, estimated trees and the true gene trees. Numbers in italic indicate the largest number of genes. OCTAL improves more genes than ASTRAL-II except in the higher ILS conditions with the RF distance criteria, in which case OCTAL and ASTRAL-II are more often equal in their performance
