For the illustration purpose of proposed model, we have shown the comparison of sample results with those
of two heuristic methods in Table 3. The best solutions of three approaches in terms of total travel distance
and the number of generations. It is known that the proposed approach is potentially efficient and useful in
solving VRP-type problem especially for the problem with a large number of nodes. In case of problem with
node 99, the total travel distance of proposed model is given by 1368 with 1752 iterations but that of heuristic
