Quasi-Hessian Approximation

bfgs

Use BFGS method to compute quasi-hessians

sr1

Use the Symmetric Rank 1 update method to compute quasi-Hessians

Description

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.
