linopy.model.Model.add_objective

linopy.model.Model.add_objective#

Model.add_objective(expr, overwrite=False, sense='min', scaling=1)#

Add an objective function to the model.

Parameters:

  • expr (linopy.LinearExpression, linopy.QuadraticExpression) – Expression describing the objective function.

  • overwrite (False, optional) – Whether to overwrite the existing objective. The default is False.

  • sense ("min" or "max", optional) – Objective sense. The default is “min”.

  • scaling (float, optional) – Positive finite scaling factor for the objective. Solver-side objective coefficients are multiplied by this factor and reported objective values are divided back. The default is 1.

Returns:

linopy.LinearExpression – The objective function assigned to the model.
