v2.4.0 #1263

benjamc · 2025-09-26T13:13:02Z

Improvements

Replace random forest from pyrfr with random forest from sklearn (Feat/replace random forest #1246)
Submit trials to runners in SMBO instead of running configs directly (Submit trials to runners in SMBO instead of running configs directly #937)
target_function becomes optional in Facade when using ask and tell exclusively ([Feature] Remove target_function as required when using ask and tell interface #946)

Documentation

Ask and tell without initial design and warmstarting

Examples

Add target function with additional arguments (Example: target function with additional arguments #1134)

Bugfixes

Ask and tell without initial design may no longer return a config from the initial design - if it is not "removed".
Addressing situations where the acquisition function suggests configurations that have already been sampled in prior iterations (Better handling of n_retries #1216)

Misc

Rename retries to max_new_config_tries in ConfigSelector (1088 smac stops before n trials #1207)
