Approximation Algorithms for Forests Augmentation Ensuring Two Disjoint Paths of Bounded Length
Given a forest F = (V, E) and a positive integer D, we consider the problem of finding a minimum number of new edges E such that in the augmented graph H = (V, E∪E ) any pair of...

Adapting to a reliable network path
We consider the model of unreliable network links, where at each time unit a link might be either up or down. We consider two related problems. The first, establishing end to end...
