چکیده
|
The graovac-pisanski number is defined in 1991 e.g. more than 50 years after the definition of wiener number by graovac and pisanski. they called this new index as modified wiener number based on the sum of distances between all the pairs (u,α(u)) where α stands in the automorphism group of given graph. in this paper, we investigate some results on the graovac-pisanski number.
