I'm solving binary MIPs using these basic steps:
mip = glp_create_prob();
glp_read_lp(mip, NULL, filename);
parm.presolve = GLP_ON;
glp_intopt(mip, &parm);
status = glp_mip_status(mip);
For all my MIPs, GLPK always says:
Problem data seem to be well scaled
Apparently it tries to scale it, and figures out it's unnecessary. I'm solving
many similar MIPs and would like it to skip this scaling step.
I tried this before calling glp_intopt():
glp_scale_prob(mip, GLP_SF_SKIP);
But, it still tells me it's well scaled. How can I skip it?
Thanks,
