[Help-glpk] infeasible solution support

[Roman Itskovich]

Hello,

My name is Roman, I #39;m an Economics student at Tel-Aviv University. I
#39;m working on solving a MILP problem which involves devising an
algorithm to solve problems in which initially there are no feasible
solutions.

I #39;ve been using Lindo as a basis for this, but later found your
algorithm - GLPK.

The problem is as follows: Lindo gives feedback when the constraint set
is infeasible (using some sort of IIS module)- it tells you what are the
necessary or sufficient constraints to remove to achieve a solution.
Your algorithm doesn #39;t have this option, or at least I wasn #39;t
able to locate such an option. I find this feedback from Lindo to
be extremely valuable to my work.

Does GLPK has something of this sort?
