function

`scipy.optimize._trustregion_ncg:_minimize_trust_ncg`

source: /scipy/optimize/_trustregion_ncg.py:11

Signature

def _minimize_trust_ncg(fun, x0, args = (), jac = None, hess = None, hessp = None, **trust_region_options)

Summary

Minimization of scalar function of one or more variables using the Newton conjugate gradient trust-region algorithm.

Parameters

initial_trust_radius : float: Initial trust-region radius.
max_trust_radius : float: Maximum value of the trust-region radius. No steps that are longer than this value will be proposed.
eta : float: Trust region related acceptance stringency for proposed steps.
gtol : float: Gradient norm must be less than gtol before successful termination.
