In order to start solving mip the glpk mip solver needs optimal solution
of its lp relaxation, which is obtained by the simplex-based solver.
If the relaxation has no feasible solution, the mip also cannot have any
integer feasible solutions, in which case the mip solver does not start
the search.
Please note that the most recent version of glpk is 4.22.
