[Help-glpk] Getting exact solution and starting from infeasible basis

[Sergio Giro]

Hi,

I started using glpk a couple of weeks ago and there are some
questions whose answers I couldn't find in the reference manual. In
case I overlooked it, please feel free to point me to the relevant
sections avoiding long answers.

- Is there any way to get the exact solution computed by glp_exact?
For big numbers, getting the double 1.2345 doesn't necessarily mean
that the exact solution was 12345/10000...

- In case the initial basis provided with the basis constructing
methods corresponds to an unfeasible solution, is this basis used in
Phase I of the simplex method as a the starting point?

Many thanks,
Sergio
