Graph colouring remains a central topic in graph theory, providing the mathematical framework for assigning colours to the elements of a graph under specific constraints. In particular, the colouring ...

Two computer scientists found — in the unlikeliest of places — just the idea they needed to make a big leap in graph theory. This past October, as Jacob Holm and Eva Rotenberg were thumbing through a ...

Jacob Holm was flipping through proofs from an October 2019 research paper he and colleague Eva Rotenberg—an associate professor in the department of applied mathematics and computer science at the ...

This example shows how to use a SAS/GRAPH Web driver to generate a drill-down graph (see About Drill-down Graphs). The example uses the HTML driver, but the principles would be the same for using the ...

* Why do you want to base this on Dijkstra's algorithm, which is designed to find a single shortest-path? Surely there are better options for your base implementation. A quick Google search suggests a ...

This example shows you how to create a drill-down graph in which the user can select an area of the graph in order to display additional information about the data. The program creates one vertical ...
