The following comments should work: 1) The effect of different vector norm such as on the convergence speed of the algorithm. 2) The effect of the rank-based ratio on the convergence speed of the algorithm. 3) We all know that there are different methods used in the selection schemes while the authors listed only one, so the authors are recommended to list at lease another selection methods such as the tournament selection (with and without replacement) and study the effect of these on the convergence speed of the algorithm. 4) Reference [18] "O. Abu Arqub, Z. Abo-Hammour, H. Rashaideh, Application of continuous genetic algorithm for second-order singular boundary value problems, The 5th International Conference on Information Technology, Jordan, (2011)" Should be cited correctly according to the journal format.
