Pull Request Overview

This PR improves the OpenMDAO (OM) driver interface by adding support for configuring optimization settings through the driver configuration. The change allows users to specify opt_settings alongside regular driver options, providing more granular control over optimization parameters.

• Adds handling for opt_settings within driver configuration options
• Maintains backward compatibility with existing driver option configuration

Using a string literal comparison for special option handling creates a magic string. Consider defining a constant like OPT_SETTINGS_KEY = "opt_settings" to make this more maintainable and reduce the risk of typos.

Suggested change

	if option == "opt_settings":
	if option == OPT_SETTINGS_KEY:

The variable name opt_setting suggests a single setting, but it's being used as a key to access value[opt_setting]. This should be prob.driver.opt_settings[opt_setting] = value[opt_setting] where value is the opt_settings dictionary. However, the current code uses the outer value which is the entire opt_settings dictionary, making this line correct but confusing due to variable naming.

Suggested change

	prob.driver.options[option] = value
	for option, opt_settings in analysis_options["driver"]["options"].items():
	if option == "opt_settings":
	for opt_name in opt_settings:
	prob.driver.opt_settings[opt_name] = opt_settings[opt_name]
	else:
	prob.driver.options[option] = opt_settings
