CONMIN conjugate gradient optimization method

Specification

• Alias: None

• Arguments: None

Child Keywords:

Required/Optional	Description of Group	Dakota Keyword	Dakota Keyword Description
Optional		max_iterations	Number of iterations allowed for optimizers and adaptive UQ methods
Optional		convergence_tolerance	Stopping criterion based on objective function or statistics convergence
Optional		constraint_tolerance	Maximum allowable constraint violation still considered feasible
Optional		speculative	Compute speculative gradients
Optional		max_function_evaluations	Number of function evaluations allowed for optimizers
Optional		scaling	Turn on scaling for variables, responses, and constraints
Optional		model_pointer	Identifier for model block to be used by a method

Description

The interpretations of the method independent controls for CONMIN are essentially identical to those for DOT.

See topic-package_dot for information related to CONMIN methods, specifically method-dot_frcg.

Expected HDF5 Output

If Dakota was built with HDF5 support and run with the environment-results_output-hdf5 keyword, this method writes the following results to HDF5:

• hdf5_results-best_params

• hdf5_results-best_obj_fncs (when responses-objective_functions) are specified)

• hdf5_results-calibration (when responses-calibration_terms are specified)
