Kernelization of Graph Hamiltonicity: Proper H-Graphs
Chaplick, Steven; Fomin, Fedor; Golovach, Petr; Knop, Dusan; Zeman, Peter (Journal article; Peer reviewed, 2021)We obtain new polynomial kernels and compression algorithms for Path Cover and Cycle Cover, the well-known generalizations of the classical Hamiltonian Path and Hamiltonian Cycle problems. Our choice of parameterization ... -
Recognizing Proper Tree-Graphs
Chaplick, Steven; Golovach, Petr; Hartmann, Tim; Knop, Dusan (Journal article; Peer reviewed, 2020)We investigate the parameterized complexity of the recognition problem for the proper H-graphs. The H-graphs are the intersection graphs of connected subgraphs of a subdivision of a multigraph H, and the properness means ...
