Abstract

In the field of parameterized computation and theory, as a pre-processing technique of algorithms, kernelization has received considerable attention. In this paper, we study the kernelization algorithms for several fixed parameter tractable problems, including Co-Path Set, Path-Contractibility and Connected Dominating Set on \(G_7\) Graphs. For these three problems, based on simple observations, we give simple kernelization algorithms with kernel size of \(4k, 3k+4\) and \(O(k^2)\) respectively, which are smaller than the previous corresponding smallest kernels \(6k, 5k+3\), and \(O(k^3)\).
