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

From: OCTAL: Optimal Completion of gene trees in polynomial time

Moderate ILS (AD = 10%)
 RF 1366 363 1271

 Quartet 1540 594 866
High ILS (AD = 35%)
 RF 1004 524 1472
 Matching 1501 920 579
 Quartet 1473 1092 435
Very high ILS (AD = 75%)

 Quartet 1552 1371 77
  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
