Abstract

The Maximum Cycle Packing problem is an important class of NP-hard problems, which has lots of applications in many fields. In this paper, we study Parameterized Planar Vertex-Disjoint Cycle Packing problem, which is to find k vertex-disjoint cycles in a given planar graph. The current best kernel size for this problem is \(1209k-1317\). Based on properties of maximal cycle packing, small cycles, degree-2 paths, and new reduction rules given, a kernel of size \(415k-814\) is presented for Parameterized Planar Vertex-Disjoint Cycle Packing problem.
