On the minmax regret path median problem on trees

作者:

Highlights:

• We study the minmax regret path median problem on a tree.

• The weight of each vertex is uncertain and is characterized by an interval.

• It is required to find a solution minimizing the worst-case loss.

• An improved O(n2)-time algorithm is presented.
