[sumo-user] --seed and --random

[ali mirzaei <alimrz222@xxxxxxxxx>]

Hello,

My new questions are in two parts:

1- Despite reading --seed and --random in https://sumo.dlr.de/docs/sumo.html#input, unfortunately, I didn't get the point. I mean the difference between these two tools of making a run randomized. Which one precedes the other? What is the relationship between them? What shall I do if I want to make my run completely randomized? 

2- What attributes of flow are randomized when I change the seed(random) tool?

Regards,

Ali
