## ◆ LBFGSBSolver()

template<typename Scalar , template< class > class LineSearch = LineSearchMoreThuente>
 LBFGSpp::LBFGSBSolver< Scalar, LineSearch >::LBFGSBSolver ( const LBFGSBParam< Scalar > & param )
inline

Constructor for the L-BFGS-B solver.

Parameters
 param An object of LBFGSParam to store parameters for the algorithm

## ◆ minimize()

template<typename Scalar , template< class > class LineSearch = LineSearchMoreThuente>
template<typename Foo >
 int LBFGSpp::LBFGSBSolver< Scalar, LineSearch >::minimize ( Foo & f, Vector & x, Scalar & fx, const Vector & lb, const Vector & ub )
inline

Minimizing a multivariate function subject to box constraints, using the L-BFGS-B algorithm. Exceptions will be thrown if error occurs.

Parameters
 f A function object such that f(x, grad) returns the objective function value at x, and overwrites grad with the gradient. x In: An initial guess of the optimal point. Out: The best point found. fx Out: The objective function value at x. lb Lower bounds for x. ub Upper bounds for x.
Returns
Number of iterations used.
