Timerank reward's index may be out of bound.

[uason7]

Thank you for providing your code，
and I think it may need to added a line of code at line 165 in class NAPFDVerdictMetric in “coleman4hcs/evalution.py”.
scheduled_time += row['Duration']
It may cause the unscheduled_testcase to be defined as scheduled_testcase, and "rewards[rank_idx]" at line 53 in "rewards.py" may be error： ’rank_idx' out of bound.
