[HTML][HTML] Reconfiguration in bounded bandwidth and tree-depth

M Wrochna - Journal of Computer and System Sciences, 2018 - Elsevier
We show that several reconfiguration problems known to be PSPACE-complete remain so
even when limited to graphs of bounded bandwidth (and hence pathwidth and treewidth) …

Quasi-polynomial time approximation schemes for the maximum weight independent set problem in H-free graphs

Computing homomorphisms in hereditary graph classes: the peculiar case of the 5-wheel and graphs with no long claws

M Dębski, Z Lonc, K Okrasa, M Piecyk… - arXiv preprint arXiv …, 2022 - arxiv.org
For graphs $ G $ and $ H $, an $ H $-coloring of $ G $ is an edge-preserving mapping from
