Our algorithm can achieve the solutions close to the best known
solutions for the cluster problem set C1 and C2. Also, our
algorithm can obtain the comparable solutions for the problem
set R1, R2, RC1 and RC2 compared with other meta-heuristics.
However, our algorithm requires more vehicle for most sets. This
can be attributed that our aim is to minimize the total distance
for VRPTW, i.e., there is no additional cost as adding a vehicle.
