On the extremal cactus graphs for variable sum exdeg index with a fixed number of cycles

The variable sum exdeg index, introduced by Vukičević [Croat. Chem. Acta 84 (2011) 87–91] for predicting the octanol-water partition coefficient of certain chemical compounds, of a graph G is defined as where a is any positive real number different from 1, V(G) is the vertex set of G and dv denotes...
