Talk:Graph colouring

Thanks for open source

I am investigating a few graph algorithms hence this task. The ASCII diagrams of graphs came from this Perl CPAN module:

graph-easy

Graphviz doesn't do ASCII output so would be difficult to add its output to RC.

Any tougher problems?

Are there any ready-made problems knocking about which might (frinst) give exhaustive search pause for thought? --Pete Lomax (talk) 22:37, 14 March 2020 (UTC)

If you mean larger data sets you may take a look at here, I haven't tried yet but did take a peek at one sample and it seems ready to be used. Hope this helps. --Hkdtam (talk) 03:39, 15 March 2020 (UTC)

Hmm, 317,080 nodes and 1,049,866 edges (for the example you peeked at) is far more than I would ever have imagined... --Pete Lomax (talk)

317,080 nodes and 1,049,866 edges in 114 colours according to the Python prog. --Paddy3118 (talk) 10:00, 16 March 2020 (UTC)
