) → tuple[Model, VariableGenerator]

Load a QPLIB file and construct a model.

The QPLIB format follows a supported subset of the QPLIB specification. Return the loaded model and its associated variable generator.

Parameters:

• filename (str | PathLike) – filename

• penalty_formulation (Literal['Default', 'IntegerVariable', 'RealVariable', 'Relaxation', 'LinearRelaxation', 'QuadraticRelaxation'] | amplify.PenaltyFormulation) – Penalty formulation used for inequality constraints. Defaults to PenaltyFormulation.Default.

Returns:

Loaded model and its associated variable generator.

Return type:

tuple[Model, VariableGenerator]
