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 ...

This example specifies a plot symbol on a SYMBOL statement and rotates the symbol through the colors list. Temperature values in the data are represented by the same plot symbol in a different color.

For graph coloring, we report on three simulated annealing schemes, all of which can dominate traditional techniques for certain types of graphs, at least when large amounts of computing time are ...
