Algorithmic generation of molecular graphs with large Merrifield-Simmons index

, 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.

Extreme Star of Phenylenes for the Merrifield-Simmons Index

Contemporary Mathematics
We identify extremal graphs concerning the number of independent sets for polyphenylene dendrimers. Specifically, we demonstrate that for a certain number of phenylenes, for example to k phenylenes, the compound formed as a star  with a phenylene core achieves the maximum Merrifield-Simmons (M-S) index for a 1-connected component with an equal number ...

Merrifield-Simmonsův index lineárních oktagonálních řetězců

, 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 ...
