Abstract
Although our arguments appear to be very technical, we explain the intuitive background by relating our results to those on unweighted sum of distances. Indeed, along with other consequences, it is easy to see that previously established extremal results on the sum of unweighted distances are simply the special cases when all edge weights are 1. Related interesting questions for potential future work are also mentioned.
