Publications related to 'kernelization' : Kernelization is a method used in fixed-parameter complexity to reduce the instance to get one whose size depends only on the value of the parameter k, and is as small as possible (polynomial, or even quadratic or linear). Then, any exact algorithm solving the problem, applied on this smaller instance obtained by applying reduction rules, will directly provide an FPT algorithm for parameter k.

"It has recently been shown that the NP-hard problem of calculating the minimum number of hybridization events that is needed to explain a set of rooted binary phylogenetic trees by means of a hybridization network is fixed-parameter tractable if an instance of the problem consists of precisely two such trees. In this paper, we show that this problem remains fixed-parameter tractable for an arbitrarily large set of rooted binary phylogenetic trees. In particular, we present a quadratic kernel. © 2013 Elsevier B.V."
