Yes, I know. But here the situation is that I arrive a place with two packages taken from two different shops, the packages are for this same place, but they are actually delivered individually.

I know here the 2 packages are simultaneously delivered because they start at the same time. I have tried to change the start time of the second delivery to the time after the first one has been delivered. It really solved the "error: for one postman, the solution must be sorted by arrival time!" error. But it still penalizes me a cost of 30 with the error "error: one order must be deliveried one time!". It's just not right.

-------------------------

This is the right answer:
D0001,S631,627,627,6,E4641
D0001,S621,628,629,2,E4490
D0001,B2706,750,759,-2,E4490
D0001,B2706,759,771,-2,E4641

The cost of it is 509, can save 579 - 509 = 70, not to mention the other benefit by saving one individual O2O order. But the evaluation program penalizes me 30 for "error: one order must be deliveried one time!", and that is just not right and should be corrected for fairness.

Yes, you are right. My neglect. So I guess the evaluation program is correct in this one.
