On the Complexity of uSPR Distance

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].
