In a specialized single-commodity network flow solver,
the arithmetic is normally exact even if done in floating point.
That is usually not true with multi-commodity flows.
If glpk floating point gives you the correct basis,
glpk exact should give you the exact answer in fairly short order.
So long as the glpk floating point basis is near-optimal and feasible,
a subsequent call to glok exact should be fairly quick.
