		Pointer< ostream >	out_solver_p_ = out_out_p,
		Pointer< ostream >	out_solver_log_p_ = out_log_p
	)			[static]

Gives a local optimizer, if available.

		char *	param_prefix = NULL,
		Pointer< ostream >	out_solver_p_ = out_out_p,
		Pointer< ostream >	out_solver_log_p_ = out_log_p
	)			[static]

Gives a LP solver, if available.

		Pointer< Param >	param,
		char *	param_prefix = NULL,
		Pointer< ostream >	out_solver_p_ = out_out_p,
		Pointer< ostream >	out_solver_log_p_ = out_log_p
	)			[static]

Gives a local optimizer for the original problem, if available.

The given problem should be the original one, only the variable bounds can be different.

)

[inline, virtual]

Reimplemented in IpOpt, and LPSolver.

Definition at line 307 of file opt.h.

virtual dvector LocOpt::get_lag_multipliers

(

)

[pure virtual]

Implemented in gamsLocOpt, IpOpt, and LPSolver.
