Middle-level data storage module for standard ALC.

This module provides data storage for coupling parameters in standard Augmented Lagrangian Coordination.

Classes

MiddleLevelDataStorageALC

Inherits from: MiddleLevelDataStorageBasis

Middle level data storage for augmented Lagrangian coordination.

Stores coupling data between subsystems using augmented Lagrangian coordination method with thread-safe access.

Methods

init(self, idparent: str, idchild: str, multiprocessing_lock: object) → None

📐 Pseudocode: Require hyperparameters γ, β and initial coupling parameters (Lines 1, 2, 3) → Augmented Lagrangian Coordination

Initialize the middle level data storage.

Args:

idparent: Identifier of the parent subsystem.
idchild: Identifier of the child subsystem.
multiprocessing_lock: Manager-created lock for multiprocessing.

createManagedMiddleLevel(self, manager: Any, lock: Any) → Any

Create a managed proxy copy of this middle level for multiprocessing.

Args:

manager: Multiprocessing manager for creating shared objects.
lock: Multiprocessing lock for synchronization.

Returns:

Managed proxy instance of this middle-level data storage.

update_state(self, other_storage: Union[MiddleLevelDataStorageALC, MiddleLevelDataStorageProxy]) → None

Update the state from another data storage instance.

This method updates the numerical information stored in the class's attributes without changing the original memory address location. This is necessary for multiprocessing, where executed subsystems return from separate processes and their state must be transferred back to the original objects in the main process.

Args:

other_storage: Source instance to copy state from.

Note:

This class defines no additional attributes beyond the base class.
The _couplingdata attribute is updated via the base class update_state(),
which iterates over each coupling object and calls its update_state() method.
