TY - JOUR T1 - COMPUTING WIENER INDEX OF HAC5C7[p, q] NANOTUBES BY GAP PROGRAM TT - JF - IJMSI JO - IJMSI VL - 3 IS - 1 UR - http://ijmsi.ir/article-1-40-en.html Y1 - 2008 SP - 1 EP - 12 KW - Nanotube KW - Wiener Index KW - Adjacent Vertices. N2 - The Wiener index of a graph Gis defined as W(G) =1/2[Sum(d(i,j)] over all pair of elements of V(G), where V (G) is the set of vertices of G and d(i, j) is the distance between vertices i and j. In this paper, we give an algorithm by GAP program that can be compute the Wiener index for any graph also we compute the Wiener index of HAC5C7[p, q] and HAC5C6C7[p, q] nanotubes by this program.
