WebA total vertex cover is a set which is both a total dominating set and vertex cover. In [5], Dutton studies total vertex covers of minimum size. He proved that, in general, the associated decision problem is NP-complete, and gives some bounds of the size of a minimum total vertex cover of a graph G in terms of t Webτ ( G) := size of minimum vertex cover. v ( G) := number of vertices in G. we prove that: τ ( G) + α ( G) = v ( G) with shows that yes if you start with a minimum vertex cover and take all the vertices it doesn't take you will be left with a …
