Class LazyRandomState

Namespace

OptunaSharp.Samplers

Assembly

OptunaSharp.dll

Lazy Random State class. Port of optuna/samplers/_lazy_random_state.py.

This is a class to initialize the random state just before use to prevent duplication of the same random state when a sampler instance is copied.

Every sampler consumes randomness through this wrapper over NumSharp's NumPy-exact MT19937 RandomState — never Random — which is what makes differential testing against Python bit-exact (plan §2 RNG discipline).
