Table 2 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 two levels of ILS and four numbers of genes

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

Number of genes OCTAL better ASTRAL-II better No difference
Moderate ILS (AD = 10%)
 25 genes 177 62 161
 50 genes 420 116 262
 100 genes 685 188 627
 200 genes 1366 363 1271
High ILS (AD = 35%)
 25 genes 228 79 93
 50 genes 398 119 283
 100 genes 624 265 611
 200 genes 1004 524 1472
  1. The RF error rate is 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 when the level of ILS is high and the number of genes is 200, in which case OCTAL and ASTRAL-II are more often equal in their performance
