Comparative analysis of symmetric division deg index as potentially useful molecular descriptor

Abstract

© 2018 Wiley Periodicals, Inc. There are several dozens of vertex–degree–based (VDB) molecular structure descriptors currently studied and proposed to be used in quantitative structure-property/activity relationships (QSPR/QSAR) researches. Among them, just a couple are recognized as promising and worth of practical applications. One of the newest is the symmetric division deg index (SDD). This article is devoted to a thorough multifaceted analysis of SDD and its comparison with other VDB topological indices. We show that the applicative potential of SDD is comparable to already well-established VDB structure descriptors. Additionally, some of conducted tests indicate its supremacy over other VDB molecular indices.
