Yes, especially if it can be used to speed up the graph colouring code
in some cases (at the moment it uses my C++ dlx solver but I'm sure
that LP etc could be useful in some other cases).
This is a fantastic addition of functionality to the Graph class.
Thanks!! I could have used some of these functions before, but had to
do without because I didn't have time to write them.
I think Nathann Cohen has done a very valuable service with the GLPK and
That said, I have a "point of order" question. Is is true or false that the
process for a package to become standard we
(1) use trac to do nomination, testing, and acceptance as an optional
(2) someone (William say) posts the spkg to
(3) after a period of a few months, voting is done for making it standard.
In any case, I vote +1 for Nathann's GLPK spkg being moved to optional
and the currently posted GLPK spkg on experimental removed, with the
idea that it be proposed for inclusion as a standard package.
If the above process is correct then there is nothing more to say.
If not, I think someone (not me) look into this PyGLPK (I am
not an OR person and have never heard of this before). By
compare, I mean, look at the license, compare Nathann's wrappers and
docstrings to PyGLPK's, etc. Maybe there are other wrappers
on the internet (I have not done a google search, just mentioning
