Detailed Description

Methods for building and solving model_builder models.

The following two sections describe the main
methods for building and solving those models.

* [`Model`](#model_builder.Model): Methods for creating
models, including variables and constraints.
* [`Solver`](#model_builder.Solver): Methods for solving
a model and evaluating solutions.

Additional methods for solving Model models:

* [`Constraint`](#model_builder.Constraint): A few utility methods for modifying
  constraints created by `Model`.
* [`LinearExpr`](#model_builder.LinearExpr): Methods for creating constraints
  and the objective from large arrays of coefficients.

Other methods and functions listed are primarily used for developing OR-Tools,
rather than for solving specific optimization problems.

Function Documentation

◆ _add_enforced_linear_constraint_to_helper()

ortools.linear_solver.python.model_builder._add_enforced_linear_constraint_to_helper	(	Union[bool, mbh.BoundedLinearExpression]	bounded_expr,
		mbh.ModelBuilderHelper	helper,
		Variable	var,
		bool	value,
		Optional[str]	name )

protected

Creates a new enforced linear constraint in the helper.

It handles boolean values (which might arise in the construction of
BoundedLinearExpressions).

If bounded_expr is a Boolean value, the linear part of the constraint is
different.
In that case, the constraint will be immutable and marked as under-specified.
Its linear part will be always feasible or infeasible whether the value is
True or False.

Args:
  bounded_expr: The bounded expression used to create the constraint.
  helper: The helper to create the constraint.
  var: the variable used in the indicator
  value: the value used in the indicator
  name: The name of the constraint to be created.

Returns:
  EnforcedLinearConstraint: a constraint in the helper corresponding to the
  input.

Raises:
  TypeError: If constraint is an invalid type.

Definition at line 115 of file model_builder.py.

◆ _add_linear_constraint_to_helper()

ortools.linear_solver.python.model_builder._add_linear_constraint_to_helper	(	Union[bool, mbh.BoundedLinearExpression]	bounded_expr,
		mbh.ModelBuilderHelper	helper,
		Optional[str]	name )

protected

Creates a new linear constraint in the helper.

It handles boolean values (which might arise in the construction of
BoundedLinearExpressions).

If bounded_expr is a Boolean value, the created constraint is different.
In that case, the constraint will be immutable and marked as under-specified.
It will be always feasible or infeasible whether the value is True or False.

Args:
  bounded_expr: The bounded expression used to create the constraint.
  helper: The helper to create the constraint.
  name: The name of the constraint to be created.

Returns:
  LinearConstraint: a constraint in the helper corresponding to the input.

Raises:
  TypeError: If constraint is an invalid type.

◆ _attribute_series()

pd.Series ortools.linear_solver.python.model_builder._attribute_series	(	*	,
		Callable[[_VariableOrConstraint], NumberT]	func,
		_IndexOrSeries	values )

protected

Returns the attributes of `values`.

Args:
  func: The function to call for getting the attribute data.
  values: The values that the function will be applied (element-wise) to.

Returns:
  pd.Series: The attribute values.

Definition at line 1364 of file model_builder.py.

◆ _convert_to_series_and_validate_index()

pd.Series ortools.linear_solver.python.model_builder._convert_to_series_and_validate_index	(	Union[bool, NumberT, pd.Series]	value_or_series,
		pd.Index	index )

protected

Returns a pd.Series of the given index with the corresponding values.

Args:
  value_or_series: the values to be converted (if applicable).
  index: the index of the resulting pd.Series.

Returns:
  pd.Series: The set of values with the given index.

Raises:
  TypeError: If the type of `value_or_series` is not recognized.
  ValueError: If the index does not match.

Definition at line 1384 of file model_builder.py.

◆ _convert_to_var_series_and_validate_index()

pd.Series ortools.linear_solver.python.model_builder._convert_to_var_series_and_validate_index	(	Union["Variable", pd.Series]	var_or_series,
		pd.Index	index )

protected

Returns a pd.Series of the given index with the corresponding values.

Args:
  var_or_series: the variables to be converted (if applicable).
  index: the index of the resulting pd.Series.

Returns:
  pd.Series: The set of values with the given index.

Raises:
  TypeError: If the type of `value_or_series` is not recognized.
  ValueError: If the index does not match.

Definition at line 1412 of file model_builder.py.

◆ _get_index()

pd.Index ortools.linear_solver.python.model_builder._get_index ( _IndexOrSeries obj )

protected

Returns the indices of `obj` as a `pd.Index`.
