The id_analytic_hessians
list specifies by number the functions which have analytic Hessians, and the id_numerical_hessians
and id_quasi_hessians
lists specify by number the functions which must use numerical Hessians and secant Hessian updates, respectively. Each function identifier, from 1 through the total number of functions, must appear once and only once within the union of the id_analytic_hessians
, id_numerical_hessians
, and id_quasi_hessians
lists.
