Wiener and Randić Indices of two types of graphs associated to some finite groups of order at most 16 / Siti Rosllydia Dania Roslly, Nur Fatimah Az Zahra Ab Halem and Nur Syasya Sahira Zailani

Topological index is a type of a molecular descriptor that is calculated based on the molecular graph of chemical compound, where molecular graph can be represented as a graph in graph theory. This research is conducted to compute degree and distance-based topological indices of two types of graphs...
