https://doi.org/10.1007/978-3-031-12292-7We propose a planarization algorithm for clustered graphs and experimentally test its efficiency and effectiveness. Further, we integrate our planarization strategy into a complete topology-shape-metrics algorithm for drawing clustered graphs in the orthogonal drawing convention.

Fast and Simple Horizontal Coordinate AssignmentWe present a simple, linear-time algorithm to determine horizontal coordinates in layered layouts subject to a given ordering within each layer. The algorithm is easy to implement and compares well with existing approaches in terms of assignment quality.

Planarization of Clustered GraphsWe propose a planarization algorithm for clustered graphs and experimentally test its efficiency and effectiveness. Further, we integrate our planarization strategy into a complete topology-shape-metrics algorithm for drawing clustered graphs in the orthogonal drawing convention.

A Characterization of DFS Cotree Critical GraphsWe give a characterization of DFS-cotree critical graphs which is central to the linear time Kuratowski finding algorithm implemented in PIGALE..

Detecting Symmetries by Branch & CutWe present a new approach for detecting automorphisms and symmetries of an arbitrary graph based on branch & cut. We derive an IP-model for this problem and have a first look on cutting planes and primal heuristics. The algorithm was implemented within the ABACUS framework; its experimental runtimes are promising.

Drawing Graphs Symmetrically in Three DimensionsIn this paper, we investigate symmetric graph drawing in three dimensions. We show that the problem of drawing a graph with a maximum number of symmetries in three dimensions is NP-hard. Then we present a polynomial time algorithm for finding maximum number of three dimensional symmetries in planar graphs.

F. C. Michel Jr,T. J. Marsh,C. A. Reddyends and portions of the edge routing have optimal height. While developing a solution, we explore the subproblems of determining the order of the layers in the diagram, assigning . and . coordinates to nodes, and routing the edges.
