virtual bool lpint::LinearProgramSolver::parameter_supported ( const Param param ) const

pure virtual

Check whether the solver backend supports the given parameter.

Parameters

param The parameter to check support for.

Returns: true The solver supports the given parameter.; false The solver does not support the given parameter.

Implemented in lpint::SoplexSolver, and lpint::GurobiSolver.

virtual void lpint::LinearProgramSolver::set_parameter	(	const Param	param,
		const int	value
	)

pure virtual

Set an integer-valued parameter in the internal LP solver. This method will fail with LpError::UnsupportedParameterError if param is not a valid parameter for the internal solver.

Parameters

param	The parameter to change.
value	The value to which to set the parameter.

Implemented in lpint::SoplexSolver, and lpint::GurobiSolver.

virtual void lpint::LinearProgramSolver::set_parameter	(	const Param	param,
		const double	value
	)

pure virtual

Set a double-valued parameter in the internal LP solver This method will fail with LpError::UnsupportedParameterError if param is not a valid parameter for the internal solver.

Parameters

param	The parameter to change.
value	The value to which to set the parameter.

Implemented in lpint::SoplexSolver, and lpint::GurobiSolver.
