[PDF][PDF] Recent developments in kernelization: A survey
S Kratsch - Bulletin of EATCS, 2014 - smtp.eatcs.org
Kernelization is a formalization of efficient preprocessing, aimed mainly at combinatorially
hard problems. Empirically, preprocessing is highly successful in practice, eg, in state-of-the …

Kernelization lower bounds by cross-composition
We introduce the framework of cross-composition for proving kernelization lower bounds. A
classical problem L\and/or-cross-composes into a parameterized problem Q if it is possible …

Compression via matroids: a randomized polynomial kernel for odd cycle transversal
S Kratsch, M Wahlström - ACM Transactions on Algorithms (TALG), 2014 - dl.acm.org
The Odd Cycle Transversal problem (OCT) asks whether a given undirected graph can be
made bipartite by deleting at most k of its vertices. In a breakthrough result, Reed, Smith, and …

Multicut is FPT
N Bousquet, J Daligault, S Thomassé - … of the forty-third annual ACM …, 2011 - dl.acm.org
Let G=(V, E) be a graph on n vertices and R be a set of pairs of vertices in V called requests.
A multicut is a subset F of E such that every request xy of R is cut by F, ie every xy-path of G …

Known algorithms for edge clique cover are probably optimal
In the Edge Clique Cover (ecc) problem, given an undirected graph G and an integer k, we
ask whether one can choose k cliques in G such that each edge of G is contained in at least …

Directed subset feedback vertex set is fixed-parameter tractable
Given a graph G and an integer k, the Feedback Vertex Set (FVS) problem asks if there is a
vertex set T of size at most k that hits all cycles in the graph. The first fixed-parameter …
