Dear Andrew,
When running the glpsol command line for the MIP model.mps everything is
OK, optimal solution is found.
But when I launch it with the --intopt option, GLPK crashes (see
crash.txt file).
It seems that for a column, ipp_tight_bnds() function returns 0, because
bounds are unchanged, which is not alloweed in reduce_bounds().
Why is it an error ?
I worked with GLP 4.28 on windows XP
Thank you very much for giving me an explanation, and best regards,
--
