the higgest score must be directly related to the best solution

Suprayitno Suprayitno

the best solution should in the last iteration. depend on your problem, minimizing or maximizing.

Abdikarim Said Sulub

Ensure that your best solution is stable and has converged. If the best solution from one of the 50 iterations significantly outperforms the others, this might indicate a good solution.
