File containing advanced QUESO options

Specification

Alias: none

Argument(s): STRING

Description

Allow power users to override default QUESO and QUESO/GPMSA options such as hyper-parameter priors, initial chain position, and proposal covariance (including hyper-parameters), which might not be accessible through Dakota user input.

Default Behavior No advanced options used.

Usage Tips The options_file offers a final override over other options settings, which are applied with the folowing precedence:

  1. QUESO library defaults
  2. Dakota hard-coded defaults
  3. Settings from Dakota input file
  4. Settings from the advaned options_file
