Polynomial-Size Enumeration Kernelizations for Long Path Enumeration
摘要
Enumeration kernelization for parameterized enumeration problems was defined by Creignou et al. [Theory Comput. Syst. 2017] and later refined by Golovach et al. [J. Comput. Syst. Sci. 2022] to polynomial-delay enumeration kernelization. We consider Enum Long-Path, the enumeration variant of the Long-Path problem, from the perspective of enumeration kernelization. Formally, given an undirected graph G and an integer k, the objective of Enum Long-Path is to enumerate all paths of G having exactly k vertices. We consider the structural parameters vertex cover number, dissociation number, and distance to clique and provide polynomial-delay enumeration kernels of polynomial size for each of these parameters.
