Minimum edge covering
Webedge cover in G. We will discuss efficient algorithms to find minimum cardinality edge covers, and minimum cost edge covers. Another type of covers usually discussed in graph theory are node covers. These are subsets of nodes X ⊂N that cover all the edges, i.e., every edge in A is incident to at least one node in X.

WebA minimum edge covering is an edge covering using the smallest possible number of edges. In the graphs below, the minimum edge covering is indicated by red edges. … WebBy definition, a directed path is a sequence of edges where each pair of consecutive edges share a vertex and all edges have the same direction. And I'll remind you that in the problem we're discussing now we cover the DAG with vertex-disjoint paths. Covering a DAG with edge-disjoint paths is much easier in fact (it's solvable by a greedy algo).
