Let G be a multidigraph with vertices V (G) and arcs A(G). G is balanced if d+G(v) = d − G(v) for every v ∈ V (G). Let ri, rj be the number of cycles in G that include ai, aj ∈ A(G) respectively, and ri ≥ rj. Local quality index of G is defined as the largest ratio ri rj for opposite arcs ai, aj . Global quality index of G is defined as the largest ratio ri rj for distinct arcs ai, aj . In this...
