As mentioned above, the whole test ({{{-long}}}) of {{{generic_graph.py}}}
- with ''in theory'' '''the same''' LP program (30 vertices) - took 281
seconds on a much slower machine.
I still don't know if the GLPK library or the Sage interface/code that
builds the LP program structure is broken on the other (very similar, btw)
machine.
(I've killed the Python process running the solver after 42138+ seconds,
which was still searching for a solution.)
Nathann, could you take a look at the variable name generation which
causes the MPS and LP file errors? (These should be reproducible on all
systems I think, at least I've met them on a 64-bit system, running Ubuntu
9.04.)
