Hi SAS/OR users,
First of all, thanks to SAS developpers for amazing works done for the OPTMODEL procedure. Really impressive!
Just one question, I currently "play" with presolver optmodel to detect constraints eliminated in a LP problem
eg : reset presolver = none; solve; expand / con;
but i didn't see any differences in SAS outputs with
solve; expand / con;
Is there any options to see the constraints removed by OPTMODEL presolver? by OPTLP presolver?
thank you
