Equivalently, label the vertices from {0, 1} so that the sum over each closed neighborhood is at least one; the minimum value of the sum of all labels, with this restriction, is the domination number. The fractional domination number gamma_f(G) is defined in the same way, except that the vertex labels are chosen from [0, 1]. Given an ordering of the vertex set of G, let gamma_g(G) be the approximation of the domination number by the st","authors_text":"Chris Hartman, Glenn G.
