		double	t_ub,
		VarType	t_type,
		double	t_obj = `0.`,
		std::string	t_name = `""`
	)

Constructor.

Creates a new variable in the optimization environment.

If no name is given, a unique name in the environment is given.

Parameters

t_env	The optimization environment.
t_lb	The lower bound (possibly `-Inf`) for the default version of the variable.
t_ub	The upper bound (possibly `+Inf`) for the default version of the variable.
t_type	The type for the default version of the variable.
t_name	The given name of the variable.

◆ Var() [2/3]

idol::Var::Var	(	Env &	t_env,
		double	t_lb,
		double	t_ub,
		VarType	t_type,
		double	t_obj,
		LinExpr< Ctr, double > &&	t_column,
		std::string	t_name = `""`
	)

Constructor.

Creates a new variable in the optimization environment.

If no name is given, a unique name in the environment is given.

Parameters

t_env	The optimization environment.
t_lb	The lower bound (possibly `-Inf`) for the default version of the variable.
t_ub	The upper bound (possibly `+Inf`) for the default version of the variable.
t_type	The type for the default version of the variable.
t_column	The column for the default version of the variable.

		VarType	t_type,
		double	t_obj,
		const LinExpr< Ctr, double > &	t_column,
		std::string	t_name = `""`
	)

t_name	The given name of the variable.

Member Function Documentation

◆ create_version()

void idol::Object< VarVersion , Var >::create_version	(	const Model &	t_model,
		unsigned int	t_index,
		ArgsT &&...	t_args
	)		const

inlineprotectedinherited

Definition at line 34 of file Object.h.

◆ get()

const ValueT & idol::Object< VarVersion , Var >::get ( const Annotation< ValueT > & t_annotation ) const

inlineinherited

Returns the value of the given annotation t_annotation associated to the object.

If no value is found, the default value of the annotation is returned. If no default value was set, an exception is thrown.

Template Parameters

ValueT The value type of the annotation.

Parameters

t_annotation The annotation.

Returns: The value of the annotation.

Definition at line 78 of file Object.h.

◆ id()

unsigned int idol::Object< VarVersion , Var >::id ( ) const

inlineinherited

Returns the id of the optimization object.

Returns: The id of the optimization object.

Definition at line 60 of file Object.h.

◆ is_in()

bool idol::Object< VarVersion , Var >::is_in ( const Model & t_model ) const

inlineinherited

Returns true if the optimization object is part of the model t_model, false otherwise.

Parameters

t_model The model.

Returns: True if the optimization object is part of the model t_model, false otherwise.

Definition at line 67 of file Object.h.

◆ make_vector()

template<unsigned int N = 1, unsigned int I = 0>

static Vector< Var, N - I > idol::Var::make_vector	(	Env &	t_env,
		const Dim< N > &	t_dim,
		double	t_lb,
		double	t_ub,
		VarType	t_type,
		double	t_obj,
		const std::string &	t_name = `""`
	)

inlinestatic

Creates a (nested) vector of variables.

Example:

Env env;
 
auto x = Var::make_vector(env, Dim<2>(m, n), 0., 1., Continuous, "x");
 
std::cout << x[1][4].name() << std::endl; // "x_1_4"

Template Parameters

N	The dimension of the (nested) vector.
I	Used for recursion.

Parameters

t_env	The environment to store the variables.
t_dim	The number of elements in each dimension.
t_lb	The lower bound.
t_ub	The upper bound.
t_type	The type of the variables.
t_name	The given name of the variables.

Returns: A (nested) vector of variables.

Definition at line 104 of file Var.h.

◆ name()

const std::string & idol::Object< VarVersion , Var >::name ( ) const

inlineinherited

Returns the name of the optimization object.

Returns: The name of the optimization object.

Definition at line 54 of file Object.h.

◆ remove_version()

void idol::Object< VarVersion , Var >::remove_version ( const Model & t_model ) const

inlineprotectedinherited

Definition at line 38 of file Object.h.

◆ set()

void idol::Object< VarVersion , Var >::set	(	const Annotation< ValueT > &	t_annotation,
		ArgsT &&...	t_args
	)		const

inlineinherited

Sets the value of the given annotation t_annotation associated to the object.

Template Parameters

ValueT	The value type of the annotation.
ArgsT	The parameter pack types for constructing the value of the annotation.

Parameters

t_annotation	The annotation.
t_args	The parameter pack arguments used to construct "in place" the value of the annotation.
