create_using(model, ostream=None, **kwds)

Take linear programming dual of a model

Return type:

ConcreteModel containing linear programming dual

Parameters:

• model (ConcreteModel) – The concrete Pyomo model to take the dual of

• ostream (None) – This is provided for API compatibility with other writers and is ignored here.

get_dual_constraint(model, primal_var)

Return the dual constraint corresponding to ‘primal_var’

Return type:

Constraint

Parameters:
