virtual void LpParser::LpDataBase::add_constraint	(	string const &	cname,
		TermArray const &	terms,
		char	compare,
		double	constant
	)

pure virtual

add constraint that terms compare constant.

Parameters

cname	constraint name
terms	array of terms in left hand side
compare	operator '<', '>', '='
constant	constant in the right hand side

Implemented in LpDataBase.

virtual void LpParser::LpDataBase::add_objective	(	bool	minimize,
		TermArray const &	terms
	)

pure virtual

add object terms

Parameters

minimize	true denotes minimizing object, false denotes maximizing object
terms	array of terms

Implemented in limbo::solvers::LinearModel< T, V >, limbo::solvers::lpmcf::LpDualMcf< T >, and LpDataBase.

virtual void LpParser::LpDataBase::add_variable	(	string const &	vname,
		double	l = `limbo::lowest< double >()`,
		double	r = `std::numeric_limits< double >::max()`
	)

pure virtual

add variable that l <= vname <= r.

Parameters

vname	variable name
l	lower bound
r	upper bound

Implemented in limbo::solvers::lpmcf::LpDualMcf< T >, and LpDataBase.

virtual void LpParser::LpDataBase::set_integer	(	string const &	vname,
		bool	binary
	)

pure virtual

set integer variables

Parameters

vname	integer variables
binary	denotes whether they are binary variables

Implemented in LpDataBase.
