Center node: "turing kernelization for finding long paths and cycles in restricted graph classes"
  Abstract: The k-Path problem asks whether a given undirected graph has a (simple) path of length k. We prove that k-Path has polynomial-size Turing kernels when restricted to planar graphs, graphs of bounded degree, claw-free graphs, or to K 3 , t -minor-free graphs. This means that there is an algorithm that, given a k-Path instance ( G , k ) belonging to one of these graph classes, computes its answer in polynomial time when given access to an oracle that solves k-Path instances of size polynomial in k in a single step. Our techniques also apply to k-Cycle, which asks for a cycle of length at least k. Polynomial-size Turing kernels are developed for k-Path and k-Cycle.These problems do not have polynomial-size traditional kernels.We introduce the Decompose-Query-Reduce framework for preprocessing.For bounded-degree graphs, colored k-Path is more difficult than normal k-Path.
