Edge harmonic index He(G) of the (chemical) graph G is based on the end-vertex degrees of edges of the line graph L(G). In this paper, the generalized formula and an algorithm (pseudocode) are given for edge harmonic index. The aim of this paper is to develop edge harmonic index for generalized carbon nanocones.
