problem.setObjective

Purpose

Sets the objective function of the problem.

Synopsis

problem.setObjective(expr, sense=xpress.minimize)

Arguments

expr	A linear or quadratic function of the variables that were added to the problem prior to this call. An error will be returned if any variable in the linear or quadratic part of the objective was not added to the problem via addVariable.
sense	Either xpress.minimize or xpress.maximize.

Example

The following example sets the objective function of the problem to [2x₁² + 3x₁x₂ + 5x₂² + 4x₁ + 4]:

x1 = xpress.var()
x2 = xpress.var()
p = xpress.problem()
p.addVariable(x1, x2)
p.setObjective(2*x1**2 + 3*x1*x2 + 5*x2**2 + 4*x1 + 4)

Further information

Multiple calls to setObjective are allowed, and each replaces the old objective function with a new one.
