The graph G,a weighted graph wG = , as follows:
wV = {(A, (1, 23)), (B, (2, 17)), (C, (3, 14)), (D, (4, 6)), (J,(5, 13)), (K, (6, 10)), (P, (5, 1)), (Q, (3, 7)), (R, (2, 5)), (X,(1, 12)), (Y, (4, 13)), ( Z, (6, 19))};
wE = {((A, B), 5), ((A, K), 4), ((A, P), 3), ((B, C), 6), ((B, Q),3), ((C, D), 2), ((C, R), 3), ((D, J), 4) ((D, X), 2), ((J, K), 2),((J, Y), 5), ((K, Z), 6), ((P, R),3), ((P, Y), 5), ((Q, X), 4),((Q, Z), 4), ((R, Y), 1), ((X, Z), 6)}
