Summary: In the Cluster Editing problem, a graph is to be changed to a disjoint union of cliques by at most \(k\) operations of edge insertion or edge deletion. Improving on the best previously known quadratic-size polynomial-time kernelization, we describe how a crown-type structural reduction rule can be used to obtain a \(6k\) kernelization bound.
