no_hessians

Hessians will not be used

## Specification

Alias: none

Argument(s): none

## Description

The `no_hessians` specification means that the method does not require Dakota to manage the computation of any Hessian information. Therefore, it will neither be retrieved from the simulation nor computed by Dakota. The `no_hessians` keyword is a complete specification for this case. Note that, in some cases, Hessian information may still be being approximated internal to an algorithm (e.g., within a quasi-Newton optimizer such as `optpp_q_newton`); however, Dakota has no direct involvement in this process and the responses specification need not include it.
