A feedback vertex set is a subset of vertices whose deletion makes the remaining graph a forest. We show that the minimum FVS (MFVS) in star convex bipartite graphs is NP-hard to find, and give a tighter lower bound on the size of MFVS in sparse random graphs, to provide further evidence on the hardness of random CSPs.
