OCTAL: Optimal Completion of gene trees in polynomial time

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

Error metric	OCTAL better	ASTRAL-II better	No difference
Moderate ILS (AD = 10%)
RF	1366	363	1271
Matching	1666	522	812
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%)
RF	906	520	1574
Matching	1643	1143	214
Quartet	1552	1371	77

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
