- `seed`: Seed for random number generator.
- `seed`: A seed for the initialization of `HEBOSampler`. Please note that the Bayesian optimization part is not deterministic even if seed is fixed due to the backend implementation.

- `constant_liar`: If `True`, penalize running trials to avoid suggesting parameter configurations nearby. Default is `False`.
