Enum FidelitySource 

pub enum FidelitySource {
    Dehb(Arc<Dehb>),
    Fixed(u64),
}

Where a trial’s fidelity (its run.steps budget) comes from.

The two arms are the two sides of the comparison the DEHB demonstration makes: Dehb lets the sampler pick a cheap or full budget per trial, Fixed always pays the full budget — plain full-fidelity search, the baseline DEHB is measured against.

Variants

Dehb(Arc<Dehb>)

The Dehb sampler decides each trial’s target fidelity via its bracket schedule (Dehb::target_fidelity). The same Arc must be handed to the study as its sampler, so the sampler that bred the configuration is the one asked what budget it was bred for.

Fixed(u64)

Every trial runs at this fixed run.steps — full-fidelity search.

Implementations

impl FidelitySource

pub fn fidelity_for(&self, trial_number: u64) -> Option<u64>

The fidelity for trial trial_number, or None when a Dehb source has no recorded job for it (only reachable for an empty space, where the caller falls back to the full fidelity).
