Upward and orthogonal planarity are W [1]-hard parameterized by treewidth

BMP Jansen, L Khazaliya, P Kindermann… - … Symposium on Graph …, 2023 - Springer
Upward planarity testing and Rectilinear planarity testing are central problems in graph
drawing. It is known that they are both NP-complete, but XP when parameterized by …

[HTML][HTML] Parameterized complexity of graph planarity with restricted cyclic orders

G Liotta, I Rutter, A Tappini - Journal of Computer and System Sciences, 2023 - Elsevier
We study the complexity of testing whether a biconnected graph G=(V, E) is planar with the
constraint that some cyclic orders of the edges incident to its vertices are allowed while …

Grid recognition: Classical and parameterized computational perspectives

S Gupta, G Sa'ar, M Zehavi - Journal of Computer and System Sciences, 2023 - Elsevier
Over the past few decades, a large body of works studied the (in) tractability of various
computational problems on grid graphs, which often yield substantially faster algorithms …

Drawn tree decomposition: New approach for graph drawing problems

S Gupta, G Sa'ar, M Zehavi - arXiv preprint arXiv:2310.05471, 2023 - arxiv.org
Over the past decade, we witness an increasing amount of interest in the design of exact
exponential-time and parameterized algorithms for problems in Graph Drawing …

Parameterized approaches to orthogonal compaction

W Didimo, S Gupta, P Kindermann, G Liotta… - … Conference on Current …, 2023 - Springer
Orthogonal graph drawings are used in applications such as UML diagrams, VLSI layout,
cable plans, and metro maps. We focus on drawing planar graphs and assume that we are …
