SIAM Journal on Discrete Mathematics, Volume 26, Issue 4, Page 1635-1656, January 2012. We show that the problem of computing the hybridization number of two rooted binary phylogenetic trees on the same set of taxa $X$ has a constant factor polynomial-time approximation if and only if the problem of computing a minimum-size feedback vertex set in a directed graph (DFVS) has a constant factor polynomial-time approximation. The latter problem, wh...
