`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.
