The study of topological indices based on distance in a graph in biological sciences, physical - chemistry and QSAR and QSPR studies started from 1947 when Harold Wiener introduced the Wiener index to establishing the relationships between physico-chemistry properties of alkenes and the structures of their molecular graphs. Recent progresses in nano technology caused more attention in calculating topological indices of important molecular graphs such as nanotubes, nanocones and fullerenes. In this monograph, we present an algorithm for computing topological indices based on distance in a...
