When recursion is better than iteration: A linear-time algorithm for directed acyclicity with few error vertices

Planarity, bipartiteness and (directed) acyclicity are basic graph properties with classic linear-time recognition algorithms. However, the problems of testing whether a given graph has k vertices whose deletion makes it planar, bipartite or a directed acyclic graph (DAG) are all fundamental NP-comp...
