INPUTS
The inputs consist in an objective function f used to check validity of the
Hessian approximation as well as an evaluation point x and the Newton decrement
lambda_newton. Furthermore, the descent direction Delta_x needs to be pro-
vided together with some options on (alpha, beta, tolerances) that feature
in backtracking line search algorithms.
Name Interpretation Type
f The objective function for which the Function handle
Armijo optimality condition is to be
checked. Calculates the objective values
f(x) and f(x+t Delta_x).
x The position at which gradients and Matrix [n_exp,n_exp]
search directions are evaluated.
lambda_newton The Newton decrement quantifying the A positive real number
decrease of the objective function in
the direction of Delta_x
Delta_x Provides the descent direction, for Matrix [n_exp,n_exp]
which a reasonable stepsize t is to be
determined. The recommended update is
then x = x + t Delta x
options Tuple containing the values for alpha, Tuple (alpha,beta,max_iter)
beta and maximum iterations to arrive
at a reasonable stepsize.
OUTPUTS
The outputs consist in the stepsize t, a real number guaranteeing that
Newton updates do not leave the psd cone.
Name Interpretation Type
t Stepsize for a robust damped Newton Real number in [0,1]
