We revisit crown decomposition for the Vertex Cover problem by giving a simple 2k-kernelization algorithm. Previously, a 2k kernel was known but it was computed using both crown decomposition and linear programming; moreover, with crown decomposition alone only a 3k kernel was known. Our refined crown decomposition carries some extra property and could be used for some other related problems. (C) 2018 Elsevier B.V. All rights reserved.
