Summary

Minimization of scalar function of one or more variables using a trust-region algorithm.

Extended Summary

Options for the trust-region algorithm are:

initial_trust_radius: initial_trust_radius
max_trust_radius: max_trust_radius
eta: eta
gtol: gtol
maxiter: maxiter
disp: disp
inexact: inexact
workers: workers
subproblem_maxiter: subproblem_maxiter

This function is called by the minimize function. It is not supposed to be called directly.
