The
competence of the proposed approach in providing quality solution for a small population
size and less number of iterations, in this work, statistical analysis for two
cases is carried out. Case 1 consists of population size 20 and itmax 20 while Case 2 has selected
population size of 30 and itmax 40 as
in Section 4.2. For both cases 50 trials
are run and results obtained are shown in Fig 4. It is clear from Fig 4 that Case
1 provides a solution which is comparable with Case 2. Case 2 has bigger population
size and more iterations but solution is not significantly better.
