Hello Pietro,

your message had to be forwarded manually because you are not subscribed
to the GLPK help list, cf.

Yes, glp_mip_col_val will return the best known integer
feasible solution.

You can use glp_mip_status to find out if any integer solution exists
and if this solution is optimal.

For a description see glpk-4.60/doc/glpk.pdf of the source distribution
available at
http://ftp.gnu.org/gnu/glpk/glpk-4.60.tar.gz

Best regards

Heinrich

Hello to everybody. I am using GLPK as a library in a software I am writing. My 
question is: if I set a timeout to a MIP search (tm_limit field in a glp_iocp 
structure) and then glp_intopt times out, how do I obtain the best known 
integer feasible solution found so far? Is it ok to use glp_mip_col_val?
Thank you
Pietro
