CADETProcess.optimization.ResultsCache

class CADETProcess.optimization.ResultsCache(use_diskcache: bool = False, directory: str | None = None, n_shards: int = 1)

Cache to store (intermediate) results.

Optinally uses diskcache library to store large objects in sqlite database.

Internal structure: [evaluation_object][step][x]

For example: [EvaluationObject 1][Evaluator 1][x] -> IntermediateResults 1 [EvaluationObject 1][Evaluator 2][x] -> IntermediateResults 2 [EvaluationObject 1][Objective 1][x] -> f1.1 [EvaluationObject 1][Objective 2][x] -> f1.2 [EvaluationObject 1][Constraint 1][x] -> g1.1

[EvaluationObject 2][Evaluator 1][x] -> IntermediateResults 1 [EvaluationObject 2][Evaluator 2][x] -> IntermediateResults 2 [EvaluationObject 2][Objective 1][x] -> f2.1 [EvaluationObject 2][Objective 2][x] -> f2.2 [EvaluationObject 2][Constraint 1][x] -> g2.1

[None][Evaluator 1][x] -> IntermediateResults 1 [Objective 3][x] -> f3 [Constraint 2][x] -> g2
