Constructor

Parameters:
  • tae_runner (ExecuteTARun) – Target algorithm execution object.
  • scenario (Scenario) – Scenario with all meta information (including configuration space).
  • stats (Stats) – Statistics of experiments; needed in case initial design already exhausts the budget.
  • traj_logger (TrajLogger) – Trajectory logging to add new incumbents found by the initial design.
  • runhistory (RunHistory) – Runhistory with all target algorithm runs.
  • rng (np.random.RandomState) – Random state
  • configs (typing.List[Configuration]) – List of initial configurations.
  • intensifier (Intensifier) – Intensification object to issue a racing to decide the current incumbent.
  • aggregate_func (typing:Callable) – Function to aggregate performance of a configuration across instances.
run() → ConfigSpace.configuration_space.Configuration[source]

Run the initial design.

Returns:incumbent – Initial incumbent configuration
Return type:Configuration
