The following page in the documentation
[http://www.sagemath.org/doc/reference/sage/graphs/graph.html]
refers to the need to install GLPK, and that chromatic_number uses the
less efficient DLX algorithm by default, as opposed to the MILP algorithm.
It's my understanding that sage now includes GLPK by default.
I'd recommend that the current version (4.8) documentation be changed to
remove the sentence:
''"This method requires you to install an optional Sage package like GLPK
or COIN-OR’s CBC."''
Additionally, we should check for other references to installing
"optional" GLPK in the documentation
