Given a graph G and an integer k, the Feedback Vertex Set (FVS) problem asks if there is a vertex set T of size at most k that hits all cycles in the graph.
Our main result is that SUBSET FEEDBACK VERTEX SET in digraphs is also fixed-parameter tractable parameterized by the size of the solution: Theorem 1. (main ...
