Plugin Discovery and Validation

ropt provides helper functions for querying installed plugins at runtime. These are useful for verifying your environment or building dynamic configurations.

get_plugin_name looks up which plugin provides a given method. It takes the plugin area and a method string — the same "plugin/method" or "method" strings used in the configuration (see Configuration) — and returns the plugin name, or None if no plugin supports the method:

from ropt.plugins import get_plugin_name

get_plugin_name("backend", "slsqp")           # "scipy"
get_plugin_name("backend", "scipy/L-BFGS-B")  # "scipy"
get_plugin_name("backend", "unknown")         # None

get_plugin_name("sampler", "scipy/default")   # "scipy"

The area is one of "backend", "sampler", "realization_filter" or "function_estimator".

validate_backend_options checks whether a set of backend-specific options is valid for a given method, raising an error if not. Call it before starting a long optimization to catch configuration mistakes early:

from ropt.utils import validate_backend_options

validate_backend_options("scipy/slsqp", {"maxiter": 200})   # ok
validate_backend_options("scipy/slsqp", {"bogus": 1})       # raises: unknown option
