On rectangle visibility graphs [chapter]

Prosenjit Bose, Alice Dean, Joan Hutchinson, Thomas Shermer
1997 Lecture Notes in Computer Science  
We study the problem of drawing a graph in the plane so that the vertices of the graph are rectangles that are aligned with the axes, and the edges of the graph are horizontal or vertical lines-of-sight  ...  Our goal is to find classes of graphs that are RVGs. We obtain several results: 1. For 1 < k < 4, k-trees are RVGs. 2. Any graph that can be decomposed into two caterpillar forests is an RVG. 3.  ...  In two-layer routing, one embeds processing components and their connections (sometimes called wires) in two layers of silicon (or other VLSI material). The components are embedded in both layers.  ...

An Approach for Mixed Upward Planarization

Markus Eiglsperger, Michael Kaufmann, Frank Eppinger
2003 Journal of Graph Algorithms and Applications  
In this paper, we consider the problem of finding a mixed upward planarization of a mixed graph, i.e., a graph with directed and undirected edges.  ...  The problem is a generalization of the planarization problem for undirected graphs and is motivated by several applications in graph drawing.  ...  The fastest algorithm was the one based on PQ-trees [11] , but its performance in terms of the solution quality was significantly lower than JM and GT.  ...

A multiple layer contour-based gridless channel router

P. Groeneveld
1990 IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems  
With the continuing advances of VLSI-technology, multiple layer channel routing has become increasingly important. A new n-layer gridless channel router is presented.  ...  Instead of the commonly employed grid it uses a set of contours as routing framework. The contours together with a set of reserved areas prevent short circuits and ensure routability of all nets.  ...  Ralph Otten and Hong Cai for their valuable comments on this topic.  ...
