xpress.expression
Class for linear and quadratic expressions. These can be used and combined to create constraints and objective function of an optimization problem. The user cannot explicitly create an object of this class, but applying sum, multiplication, and squaring of variables and constants gives rise to an object of this type.
import xpress as xp p = xp.problem() x = p.addVariable() y = p.addVariable() e = x**2 + 2*y - 5
