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…
A Walk on the Wild Side: a Shape-First Methodology for Orthogonal Drawings
Giordano Andreola, Susanna Caroppo, Giuseppe Di Battista +3
Several algorithms for the construction of orthogonal drawings of graphs, including those based on the Topology-Shape-Metrics (TSM) paradigm, tend to prioritize the minimization of…
Unit Edge-Length Rectilinear Drawings with Crossings and Rectangular Faces
Patrizio Angelini, Carla Binucci, Giuseppe Di Battista +5
Unit edge-length drawings, rectilinear drawings (where each edge is either a horizontal or a vertical segment), and rectangular face drawings are among the most studied subjects in…
Ranking and Unranking of the Planar Embeddings of a Planar Graph
Giuseppe Di Battista, Fabrizio Grosso, Giulia Maragno +1
Let be the set of all the planar embeddings of a (not necessarily connected) -vertex graph . We present a bijection from to the natural number…
