bool cppad_ipopt::cppad_ipopt_nlp::eval_f	(	Index	n,
		const Number *	x,
		bool	new_x,
		Number &	obj_value
	)		[virtual]

Evaluate the objective fucntion f(x).

Parameters:

[in]	n	is the dimension of the argument space for f(x); i.e., must be equal n_.
[in]	x	is a vector of size n containing the point at which to evaluate the function f(x).
[in]	new_x	is false if the previous call to any one of the Evaluation Methods used the same value for x.
[out]	obj_value	is the value of the objective f(x) at this value of x.

Returns:

The return value is always true; see Evaluation Methods.

Efficiency

This routine could be more efficient (for certain when when L[k] > 1 and retape[k] is true) if the users also provided a version of the function fg_info->eval_r(k, u) where u was of type NumberVector.
