StandardForm

(class from pyomo.core.plugins.transform.standard_form)

class pyomo.core.plugins.transform.standard_form.StandardForm(**kwds)

Bases: IsomorphicTransformation

Produces a standard-form representation of the model. This form has the coefficient matrix (A), the cost vector (c), and the constraint vector (b), where the ‘standard form’ problem is

\[\begin{split}\min/\max\ & c'x \\ s.t.\ & Ax = b \\ & x >= 0\end{split}\]

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
