No. Not their sum. For example this problem:

Object: minimize X
Constraint:  X+Y>=8, Y=min(Z1,Z2) Z1=...., Z2<.....

Do I describe Y as "Y<=Z1, Y<=Z2" ? That is not correct unless I maxmize Y in my object at the same time as minimizing X. So I asked whether multiple objects are functional.

I am running a project that need to minimize more than one variable in
LP solver. Can GLPK do that? If yes, how to do so?

Minimize their sum?
