| dc.description.abstract | For a collection F of graphs, the F-CONTRACTION problem takes a graph G and an integer k as input and decides if G can be modified to some graph in F using at most k edge contractions. The F-CONTRACTION problem is NP-Complete for several graph classes F. Heggernes et al. (2014) [4] initiated the study of F-CONTRACTION in the realm of parameterized complexity. They showed that it is FPT if F is the set of all trees or the set of all paths. In this paper, we study F-CONTRACTION where F is the set of all cactus graphs and show that we can solve it in 2O(k) center dot |V(G)|O(1) time. | en_US |
