Lab4 exercise 3 issue

[jlyw1017]

Hey,
As far as I understand, exercise 3 is about finding the best result generated by the given code.
My optimization converged, and the first two exercises passed, but all of the results could not pass the grading.

best_result_index = 0 1 2 3 4 no matter what here
grade_lab4_ex3(res_list[best_result_index])

Can anyone help with this issue?
Thx!

I also have issues with the grader, but I think they will not be addressed. I tried the other route, but it was impossible. I like the challenge but am completely disappointed with the grader system. My only hope is that the answers will be provided in the end.
