The Hosoya indices and Merrifield–Simmons indices of graphs with connectivity at most k [PDF]

open access: yes, 2012
The Hosoya index and the Merrifield–Simmons index of a graph are defined as the total number of the matchings (including the empty edge set) and the total number of the independent vertex sets (including the empty vertex set) of the graph, respectively ...

Algorithmic generation of molecular graphs with large Merrifield-Simmons index

open access: yes, 2014
The Merrifield-Simmons index is related to several physicochemical characteristics and is thus of use in combinatorial chemistry, e.g. in drug design and molecu-lar recognitions.

Merrifield-Simmonsův index lineárních oktagonálních řetězců

open access: yes, 2019
The Merrifield-Simmons index for a simple undirected graph G=(V,E) is given by the number of subsets U of V such that no two vertices in U are adjacent. This number is one of the most popular topological index in chemistry, which was firstly defined and ...
