While there has been a large literature on AFC methods, the best in terms of empirical performance was $$DCM_{NJ},$$published in SODA 2001. The main empirical advantage of $${DCM}_{NJ}$$over other AFC methods is its use of neighbor joining (NJ) to construct trees on smaller taxon subsets, which are then combined into a tree on the full set of species using a supertree method; in contrast, the other AFC methods in essence depend on quartet trees that are computed independently of each other, which reduces accuracy compared to neighbor joining. However, $${DCM}_{NJ}$$is unlikely to scale to large datasets due to its reliance on supertree methods, as no current supertree methods are able to scale to large datasets with high accuracy.
