" Many interesting problems can be reduced to graph-theoretic terms, so computational questions arising in searching graphs remain important. The problem of finding minimum feedback vertex sets (that is, the lowest cardinality set of vertices containing at least one node from every directed cycle) in a graph is NP-complete. A new paper unifies previous work on some types of graphs for which the problem can be solved in polynomial time.
