Bases: Transformation

__init__()[source]

Methods

`__init__`()
`apply`(model, **kwds)	DEPRECATED.
`apply_to`(model, **kwds)	Apply the transformation to the given model.
`create_using`(model, **kwds)	Create a new model with this transformation
`reduce_collocation_points`(instance[, var, ...])	This method will add additional constraints to a model to reduce the number of free collocation points (degrees of freedom) for a particular variable.

apply(model, **kwds): DEPRECATED.

Deprecated since version 4.3.11323: Transformation.apply() has been deprecated. Please use either Transformation.apply_to() for in-place transformations or Transformation.create_using() for transformations that create a new, independent transformed model instance.

apply_to(model, **kwds): Apply the transformation to the given model.

create_using(model, **kwds): Create a new model with this transformation

reduce_collocation_points(instance, var=None, ncp=None, contset=None)[source]

This method will add additional constraints to a model to reduce the number of free collocation points (degrees of freedom) for a particular variable.

Parameters:

instance (Pyomo model) – The discretized Pyomo model to add constraints to
var (pyomo.environ.Var) – The Pyomo variable for which the degrees of freedom will be reduced
ncp (int) – The new number of free collocation points for var. Must be less that the number of collocation points used in discretizing the model.
contset (pyomo.dae.ContinuousSet) – The ContinuousSet that was discretized and for which the var will have a reduced number of degrees of freedom
