Product Structure Meets Track Layouts
Michael A. Bekos, Giordano Da Lozzo, Petr Hliněný +1
A track layout of a graph is a partition of its vertices into linearly ordered independent sets, called tracks, such that no two edges between the same pair of tracks cross. Given…
Extending Biconnected Straight-Line Planar Drawings
Giordano Andreola, Susanna Caroppo, Giordano Da Lozzo +5
The Partial Drawing Extensibility problem, for short PDE, takes as input a triple , where is a planar graph, is a subgraph of , and is a st…
Beyond Degree Four: Near-Orthogonal Planar Drawings
Patrizio Angelini, Sabine Cornelsen, Giordano Da Lozzo +2
Orthogonal planar drawings constitute a classical and mainstream research topic in graph drawing due to their clarity and wide applicability. In an orthogonal planar drawing of a g…
Internally-Convex Drawings of Outerplanar Graphs in Small Area
Michael A. Bekos, Giordano Da Lozzo, Fabrizio Frati +2
A well-known result by Kant [Algorithmica, 1996] implies that -vertex outerplane graphs admit embedding-preserving planar straight-line grid drawings where the internal faces ar…
Upward Pointset Embeddings of Planar st-Graphs
Carlos Alegria, Susanna Caroppo, Giordano Da Lozzo +5
We study upward pointset embeddings (UPSEs) of planar -graphs. Let be a planar -graph and let be a pointset with . An UPSE of …
