Spirality and Rectilinear Planarity Testing of Independent-Parallel SP-Graphs
Walter Didimo, Michael Kaufmann, Giuseppe Liotta +1
We study the long-standing open problem of efficiently testing rectilinear planarity of series-parallel graphs (SP-graphs) in the variable embedding setting. A key ingredient behin…

Rectilinear Planarity Testing of Plane Series-Parallel Graphs in Linear Time
Walter Didimo, Michael Kaufmann, Giuseppe Liotta +1
A plane graph is rectilinear planar if it admits an embedding-preserving straight-line drawing where each edge is either horizontal or vertical. We prove that rectilinear planarity…

Optimal Orthogonal Drawings of Planar 3-Graphs in Linear Time
Walter Didimo, Giuseppe Liotta, Giacomo Ortali +1
A planar orthogonal drawing of a planar graph is a geometric representation of such that the vertices are drawn as distinct points of the plane, the edges are drawn as…
