Hello everybody !!!
Here are two new functions for the Graph class in Sage : vertex_coloring
and edge_coloring.
If you have no LP Solver installed, you can download GLPK or CBC from this
address : http://www.sagemath.org/packages/optional/
These functions should be ---way--- more efficient than the previous ones,
regardless of the Linear Solver you chose to use.
