Comparison between Merrifield–Simmons Index and Wiener Index of Graphs
文献摘要：
The Merrifield–Simmons indexσ is the total number of independent vertex sets (including the empty set) of the graph G. The Wiener index W is the sum of distances in all unordered pairs of vertices of G. We construct some new graphs satisfyingσ＞W and W＞σ, respectively. In particular, infinite graphs satisfying W ＞σ are invented with graphs with diameter 2 and infinite ones satisfying σ＞ W are discovered with so-called universally diametrical graphs.
