A fuzzy graph-based Kulli-Basava descriptor for isomer discrimination and physicochemical property prediction

In this paper, a generalized fuzzy Kulli-Basava index ($$FKB^{*}_1$$) of fuzzy graphs is introduced, which is an extension of the classical index, by introducing a fuzzy vertex degree, fuzzy edge membership value, and fuzzy sum of the degree of incident vertices. Unlike existing fuzzy topological de
