Abstract
We consider connectivityaugmentation problems in a setting where each potential new edge has a nonnegative cost associated with it, and the task is to achieve a certain connectivity target with at most p new edges of minimum total cost. The main result is that the minimum cost augmentation of edgeconnectivity from k1 to k with at most p new edges is fixedparameter tractable parameterized by p and admits a polynomial kernel. We also prove the fixedparameter tractability of increasing edgeconnectivity from 0 to 2, and increasing nodeconnectivity from 1 to 2. © 2013 SpringerVerlag.
