Comparison between Merrifield-Simmons Index and Wiener Index of Graphs
In a graph \(G=(V,E)\), the Merrifield-Simmons index of \(G\), \(\sigma(G)\), is the total number of independent sets (including the empty set) in \(G\). The Wiener index of \(G\) is defined as \(W(G)= \sum_{\{u,v\} \subseteq V}d_G(u,v)\). It is known that these two invariants are not comparable, i.e.\ there exist graphs \(G\) with \(\sigma(G) < W(G)\)

Maxima and Minima of the Hosoya Index and the Merrifield-Simmons Index
The Hosoya index and the Merrifield-Simmons index are typical examples of graph invariants used in mathematical chemistry for quantifying relevant details of molecular structure. In recent years, quite a lot of work has been done on the extremal problem for these two indices, i.e., the problem of determining the graphs within certain prescribed classes
