BetweenSteps_Transformation

(class from pyomo.gdp.plugins.between_steps)

class pyomo.gdp.plugins.between_steps.BetweenSteps_Transformation[source]

Bases: Transformation

Transform disjunctive model to equivalent MI(N)LP using the between steps transformation from Konqvist et al. 2021 [1].

This transformation first calls the ‘gdp.partition_disjuncts’ transformation, resulting in an equivalent GDP with the constraints partitioned, and then takes the hull reformulation of that model to get an algebraic model.

Methods

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

Member Documentation

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
