In the case of solving the problem using glp_simplex, is there any way

retrieve the solution in between iterations?
Look up callbacks.
Thanks for the advice.
I've tried to use the simplex algo to obtain an optimal basis.
Then, I made attached the callback listener, implemented printout of
solution at GLP_IBINGO, and used glp_intopt but i seem to be getting
solutions that do not relate to the original problem data.
I was mistaken. glp_simplex does not do callbacks.
If, as I previously inferred, you have a continous LP,
one solves it with glp_simplex.
To get the behaviour requested, one would have to edit the source code.
Print every solution after phase 1.
If you have an MILP, GLP_IBINGO is probably what you want.
Why it is not working for you, I do not know.
IIRC there are differences in how one fetches
solutions from glp_simplex and from glp_intopt.
