AbstractWe study the parameterized complexity of the following SPLIT CONTRACTION problem: Given a graph G, and an integer k as parameter, determine whether G can be modified into a split graph by contracting at most k edges. We show that SPLIT CONTRACTION can be solved in FPT time 2(0(k2))n(5), but admits no polynomial kernel unless NP C coNP/poly. (C) 2015 Elsevier B.V. All rights reserved.
