WebWhen we work with graphs, it's helpful to be able to talk about the set of vertices and the set of edges. We usually denote the vertex set by V V V V and the edge set by E E E E. When we represent a graph or run an … Web5. A vertex cover may not be a dominating set if you have a degree zero vertex outside your vertex cover. The vertex cover 'covers' all the edges, but the degree zero vertex is not adjacent to the vertex cover. A dominating set may not be a vertex cover if there is an edge, say e = (u,v), where u and v are both outside the dominating set.
