kandi X-RAY | Graph-Drawing Summary

Graph-Drawing is a C++ library typically used in User Interface, Example Codes applications. Graph-Drawing has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This repository contains the report and code for my senior thesis paper on graph drawing algorithms. In mathematics, graphs are a collection of nodes connected to each other by vertices. More concretely, a social network (e.g. Facebook) can be thought of a graph if nodes represent people and vertices represent friendships. Because of the importance of graphs in many fields outside math, including computer science, algorithms for the visualization of graphs have been widely studied. In my paper, I give extra attention to three selected algorithms. And of course, for my original inspiration read this book.

The lists within the nlist define groupings of nodes that are going to be placed on concentric circles (shells). The nodes are defined by their ID which we defined in the grafoPetersen: 1, 2, ..., 10

QUESTION

Boost C++ - Ordering size not the same as graph size

Asked 2017-Jan-13 at 20:00

As a follow up to my question Boost graph segmentation fault and to the older question Planar graph drawing C++, I have a planar graph in Boost that is not maximal planar but it has at least three edges. I call make_connected, make_biconnected_planar and make_maximal_planar on it so that it should now be maximal planar.

When I call planar_canonical_ordering on it, the ordering should be the same size as the original graph, but it is not for certain graphs, which causes a segmentation fault in chrobak_payne_straight_line_drawing because the ordering is of size < 3.

What I don't understand is why the planar canonical ordering is not the same size as the graph itself. Certainly, there are specific edges that could be added to the graph to increase its ordering size, as noted in the answer to the first question, but that is not a general case. If the graph is maximal planar, why is its ordering (ordering.size()) not the same size as the graph (num_vertices(g)) itself?

Although as in Boost graph segmentation fault I was calling all the functions necessary to make the graph maximal planar, I was not storing the vertices in the graph.
