Abstract: In nonlinear optimisation, using exact Hessian computations (full-Newton) hold superior convergence properties over quasi-Newton methods or gradient-based methods. However, for medium and large scale problems, computing the Hessian can be computationally expensive and thus time-consuming.… read more here.
