[Help-glpk] Optimality!

[Bernt-Ola Sandström]

Hello!

Is there a way one can tell if (using glpsol) a solution is unique or if
the optimum lies along an edge for example?

I had a test problem where I got a optimum solution, but when I tried
the problem using the Interior point solver I got the same optimum value
but different values for the variables. Trying Clp from coin-or gave a
third results for the variables but the same optimum. And when I ran
this problem as an integer problem I got an answer but when I tried the
same with Symphony and Sbb both said there is no integer solution.

Regards!
