Hi @ryznefil
Yes this is correct. Given the time limit of the episodes it is hard to finish with all agents in time. Thus if you are able to manage traffic as good as possible by finishing the most agents your solution is considered better.
As in round 1 we expet many participants to achieve similar or the same score. Therefor we rank the same scores according to how fast the agents reach their target by looking at the normalized reward.
Hope this helps.
Best regards,
Erik
