Maintenance of the Microcosm N-System,ossings is one of the most important aesthetic measures for nice drawings of graphs [.]. The aim of this note is to demonstrate on two standard graph drawing models that in provably good drawings, with respect to the crossing number measure, the fractional length criterion is closely related to the crossing number criterion.

The algorithm can be applied without change to cyclic or acyclic digraphs, and even to graphs containing both directed and undirected edges. We also derive a hierarchy index from the input digraph, which quantitatively measures its amount of hierarchy.

Potential applications for this kind of drawing algorithm include the generation of schematic maps from geographic networks and interactive orthogonal graph drawing.

We then describe a separation algorithm for two classes of valid inequalities that we have identified - one of which is facet-defining - and discuss their efficacy.

https://doi.org/10.1007/978-4-431-54508-8We give a linear-time algorithm to decide whether a graph has a planar LL-drawing, i.e. a planar drawing on two parallel lines. This has previously been known only for trees. We utilize this result to obtain planar drawings on three lines for a generalization of bipartite graphs, also in linear time.
