DualTransformation

class pyomo.duality.lagrangian_dual.DualTransformation(**kwds)[source]

Creates a standard form Pyomo model that is equivalent to another model

Options: dual_constraint_suffix Defaults to _constraint dual_variable_prefix Defaults to p_ slack_names Defaults to auxiliary_slack excess_names Defaults to auxiliary_excess lb_names Defaults to _lower_bound ub_names Defaults to _upper_bound pos_suffix Defaults to _plus neg_suffix Defaults to _minus

__init__(**kwds)[source]: DEPRECATED.

Deprecated since version 5.6.2: Use of the pyomo.duality package is deprecated. There are known bugs in pyomo.duality, and we do not recommend the use of this code. Development of dualization capabilities has been shifted to the Pyomo Adversarial Optimization (PAO) library. Please contact William Hart for further details (wehart@sandia.gov).

Methods

`__init__`(**kwds)	DEPRECATED.
`apply`(model, **kwds)	DEPRECATED.

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.
