Hi,
I have a graph whose number of nodes and number of edges are 2676 and 5622 respectively. I convert this graph to DAG with feedback vertex set algorithm. Then I verified the result whether it is acyclic or not. Unfortunately, it is not acyclic.
I used Python and I use the following line to convert it.
G.delete_edges(G.feedback_arc_set())
Is this a bug or did I miss something?
