Kernel(s) for Problems with No Kernel: On Out-Trees with Many Leaves
(Peer reviewed; Journal article, 2009)The {\sc \(k\)-Leaf Out-Branching} problem is to find an out-branching, that is a rooted oriented spanning tree, with at least \(k\) leaves in a given digraph. The problem has recently received much attention from the ... -
Parameterized complexity of the spanning tree congestion problem
(Peer reviewed; Journal article, 2012-09)We study the problem of determining the spanning tree congestion of a graph. We present some sharp contrasts in the parameterized complexity of this problem. First, we show that on apex-minor-free graphs, a general class ...
