Parameterized Algorithms for Non-separating Trees and Branchings in Digraphs

A well known result in graph algorithms, due to Edmonds, states that given a digraph D and a positive integer ℓ , we can test whether D contains ℓ arc-disjoint out-branchings in polynomial time. However, if we ask whether there exists an out-branching and an in-branching which are arc-disjoint, then...
