add_constraint()

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.

add_objective()

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::LinearModel< float, int32_t >, limbo::solvers::lpmcf::LpDualMcf< T >, and LpDataBase.

add_variable()

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.

set_integer()

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.
