sourcepub fn maxiter(self, maxiter: usize) -> Self
pub fn maxiter(self, maxiter: usize) -> Self
Set the maximum number of iterations in the optimization process
The Newton’s method is an iterative optimization process, which uses the first and second
order gradients to find optimal A
and B
. This function caps the maximal number of
iterations.
sourcepub fn minstep(self, minstep: F) -> Self
pub fn minstep(self, minstep: F) -> Self
Set the minimum stepsize in the line search
After estimating the Hessian matrix, a line search is performed to find the optimal step size in each optimization step. In each attempt the stepsize is halfed until this threshold is reached. After reaching the threshold the algorithm fails because the desired precision could not be achieved.
