Newton's Method - Hessian Modification (Antonio Frangioni)
More on Newton's method. How to deal with the nonconvex case: Hessian modifications (two versions), trust region (hint). Convergence properties. MATLAB code, behavior on some examples: fantastically fast convergence, but tendency of getting trapped into local minima (and high iteration cost).
