template<typename Scalar>

NonlinearCGUtils::ESolveReturn OptiPack::NonlinearCG< Scalar >::doSolve	(	const Ptr< Thyra::VectorBase< Scalar > > &	p,
		const Ptr< ScalarMag > &	g_opt,
		const Ptr< const ScalarMag > &	g_reduct_tol = `Teuchos::null`,
		const Ptr< const ScalarMag > &	g_grad_tol = `Teuchos::null`,
		const Ptr< const ScalarMag > &	alpha_init = `Teuchos::null`,
		const Ptr< int > &	numIters = `Teuchos::null`
	)

Perform a solve.

Parameters

p	[in/out] On input `p` is the initial guess for the solution. On output, will be the final estimate for the solution.
g_opt	[out] On output, `*g_opt` will be set to the final value of the objective function.
tol	[in] If `!is_null(tol)`, then `*tol` will be the tolerance used to determine the convergence of the algorithm by comparing to `norm(g_grad)` (where `norm(...)` is the natural norm defined by the vector spaces scalar product). If `is_null(tol)`, then the tolerance will be determined in some other way.
alpha_init	[in] If `!is_null(alpha_init)`, then `*alpha_init` will be the initial line search step length on the very first nonlinear CG iteration. If `is_null(alpha_init)`, the initial step length will be determined automatically.
numIters	[out] If `nonnull(numIters)`, then on output `*numIters` gives the number of iterations taken by the algorithm.

Returns: Returns true if the solution was found. Returns false if a line search failure is encountered.
