no_hessians

Hessians will not be used

Specification

  • Alias: None

  • Arguments: 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.
