We show that subtree prune and regraft (uSPR) distance on unrooted trees is fixed parameter tractable with respect to the distance. We also make progress on a conjecture of Steel [9] on the preservation of uSPR distance under chain reduction, improving on lower bounds of Hickey et al. [7].
Phylogeny, analysis of algorithms, fixed parameter tractability.
