I have a large-scale MIP proble which can have 300 thousand interger variables, 400 thousand continous variables and 200 thousand constraints. it runs well and i can get the result. However, I want to figure out why the result acts like this. For example, some interger variables are 1 and some are 0. I want to know what constraints affect this interger variables. I can do it myself if it is a small MIP proble. For a large one, is there an efficient way?
I will appreciate if there is any idea.
