The `TorchExperiment._evaluate()` method returns a metadata dictionary, but it's always empty `{}`. See [this line](https://github.com/SimonBlanke/Hyperactive/blob/main/src/hyperactive/experiment/integrations/torch_lightning_experiment.py#L180) (the empty dict is never updated). This is inconsistent with other Hyperactive integrations (sklearn, sktime)...

Following up on issue #84: Decreasing `step_size` parameter does not lead to the expected improvement in convergence precision for local optimization algorithms **Expected Behavior** When decreasing `step_size`, optimizers should be...

Following up on issue #84: PSO fails to fully converge on simple convex problems. **Expected Behavior** PSO should converge effectively on simple convex optimization problems like the sphere function. **Actual...

Search-space API change in version 2.0

1

Introduce a dataclass API for defining search spaces. This replaces the v1 “dict of numeric arrays” API and unlocks continuous ranges, SciPy distributions, categorical values, constants, and unions of spaces...
